触摸屏检测装置、触控装置及便携式电子设备Touch screen detection device, touch device and portable electronic equipment

技术领域technical field

本实用新型涉及电子设备设计及制造技术领域，特别涉及一种触摸屏及触控装置、一种便携式电子设备。 The utility model relates to the technical field of electronic equipment design and manufacture, in particular to a touch screen, a touch control device and a portable electronic equipment. the

背景技术Background technique

目前触摸屏的应用范围从以往的银行自动柜员机，工控计算机等小众商用市场，迅速扩展到手机，PDA（个人数字助理），GPS（全球定位系统），PMP（MP3，MP4等），甚至平板电脑等大众消费电子领域。用于触摸屏具有触控操作简单、便捷、人性化的优点，因此触摸屏有望成为人机互动的最佳界面而迅速在便携式设备中得到了广泛应用。 At present, the application range of touch screen has rapidly expanded from the small commercial market such as bank automatic teller machines and industrial computers to mobile phones, PDA (personal digital assistant), GPS (global positioning system), PMP (MP3, MP4, etc.), and even tablet computers. and other mass consumer electronics fields. The touch screen has the advantages of simple, convenient and humanized touch operation, so the touch screen is expected to become the best interface for human-computer interaction and has been widely used in portable devices. the

电容触摸屏通常被分为自电容和互电容两类。如图1所示，为现有技术中常见的一种自电容触摸屏的结构图。该自电容触摸屏主要有双层的菱形结构感应单元100’和200’，其检测原理是对X轴和Y轴分别扫描，如果检测到某个交叉点的电容变化超出了预设范围，则将该行和列的交叉点做为触摸坐标。虽然该自电容触摸屏的线性度较好，但是经常有鬼点出现，难以实现多点触摸。此外，由于采用双层屏，也会导致结构及成本大幅增加，并且菱形结构在电容变化量很小的情况下会出现坐标飘移，受外界干扰影响大。 Capacitive touch screens are generally divided into two categories: self-capacitance and mutual capacitance. As shown in FIG. 1 , it is a structure diagram of a common self-capacitance touch screen in the prior art. The self-capacitance touch screen mainly has double-layer diamond-shaped structure sensing units 100' and 200'. The detection principle is to scan the X-axis and Y-axis respectively. The intersection of the row and column is used as touch coordinates. Although the linearity of the self-capacitance touch screen is good, ghost points often appear, making it difficult to realize multi-point touch. In addition, due to the use of double-layer screens, the structure and cost will also be greatly increased, and the rhombus structure will have coordinate drift when the capacitance change is small, and it will be greatly affected by external interference. the

如图2a所示，为现有技术中常见的另一种自电容触摸屏的结构图。该自电容触摸屏采用三角形图形屏结构。该自电容触摸屏包括基板300’、设置在基板300’之上的多个三角形感应单元400’、和每个三角形感应单元400’相连的多个电极500’。如图2b所示，为三角形自电容触摸屏的检测原理。如图所示，椭圆表示手指，S1、S2表示手指与两个三角形感应单元的接触面积。假设坐标原点在左下角，则横坐标X=S2/(S1+S2)*P，其中，P为分辨率。当手指向右移动时，由于S2不是线性增大，所以X坐标存在一个偏差。从上述原理可以看出，目前的三角形感应单元是单端检测，即只从一个方向检测，然后通过算法算出两个方向的坐标。虽然该自电容触摸屏结构更为简单，但并没有针对屏幕的电容感应进行优化，电容变化量小，从而导致信噪比不够。此外，由于该感应单元为三角形，当手指横向移动时面积不是线性增大，因此线性度较差，导致了坐标计算发生偏移，线性度不够好。 As shown in FIG. 2 a , it is a structure diagram of another common self-capacitance touch screen in the prior art. The self-capacitance touch screen adopts a triangular graphic screen structure. The self-capacitance touch screen includes a substrate 300', a plurality of triangular sensing units 400' disposed on the substrate 300', and a plurality of electrodes 500' connected to each triangular sensing unit 400'. As shown in Figure 2b, it is the detection principle of a triangular self-capacitance touch screen. As shown in the figure, the ellipse represents the finger, and S1 and S2 represent the contact area between the finger and the two triangular sensing units. Assuming that the coordinate origin is at the lower left corner, the abscissa X=S2/(S1+S2)*P, where P is the resolution. When the finger moves to the right, since S2 does not increase linearly, there is a deviation in the X coordinate. It can be seen from the above principles that the current triangular sensing unit is single-ended detection, that is, it only detects from one direction, and then calculates the coordinates of the two directions through an algorithm. Although the structure of the self-capacitance touch screen is simpler, it is not optimized for the capacitive sensing of the screen, and the capacitance change is small, resulting in insufficient signal-to-noise ratio. In addition, since the sensing unit is a triangle, the area does not increase linearly when the finger moves laterally, so the linearity is poor, which leads to offset in the coordinate calculation, and the linearity is not good enough. the

此外，该电容感应单元输出电容变化量很小，达到飞法级，其电缆杂散电容的存在，对测量电路提出了更高的要求。而且，杂散电容会随温度、位置、内外电场分布等诸多因素影响而变化，干扰甚至淹没被测电容信号。此外，对于单层电容来说，由 于Vcom电平信号的影响会对感应电容形成严重的干扰，其中，Vcom电平信号是为了防止LCD屏幕液晶老化而不停翻转的电平信号。 In addition, the output capacitance of the capacitive sensing unit varies very little, reaching the femtofarad level, and the existence of stray capacitance of the cable puts forward higher requirements for the measurement circuit. Moreover, stray capacitance will change with the influence of many factors such as temperature, location, internal and external electric field distribution, etc., which will interfere or even submerge the measured capacitance signal. In addition, for single-layer capacitors, due to the influence of the Vcom level signal, it will cause serious interference to the sensing capacitor. Among them, the Vcom level signal is a level signal that is constantly flipped to prevent the LCD screen from aging. the

本实用新型实施例第四方面还提出了一种便携式电子设备，包括如上所述的触摸屏检测装置。 According to the fourth aspect of the embodiment of the present invention, a portable electronic device is provided, including the above-mentioned touch screen detection device. the

For example, in one embodiment of the present invention, the proportional relationship between the first resistance and the second resistance can be based on the first and/or second electrode detected from the first electrode and/or the second electrode when charging/discharging the self-capacitance. The proportional relationship between the detected value and the second detected value is calculated. Therefore, compared with the existing self-capacitance detection method, this method can greatly improve the detection accuracy and the S/N ratio of the circuit, reduce the circuit noise, and improve the induction linearity. Moreover, since the touched sensing unit is charged or discharged during the detection process, a small current will be generated therein, thereby enhancing the anti-interference ability. the

具体实施方式Detailed ways

下面详细描述本实用新型的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本实用新型，而不能解释为对本实 用新型的限制。 Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiment described below by referring to the accompanying drawings is exemplary, only for explaining the utility model, and can not be construed as the limitation of the utility model. the

本实用新型实施例提出了一种新颖的自电容检测方式，在感应单元被触摸时，触摸点可以将该感应单元分为两个电阻，在进行自电容检测的同时考虑这两个电阻就可以确定触摸点在该感应单元上的位置。如图3所示，为本实用新型实施例触控装置的检测原理示意图。当手指触摸该感应单元时，将相当于将该感应单元分割为两个电阻，这两个电阻的阻值与触摸点的位置相关。例如，如图所述，当触摸点与第一电极较近时，则电阻R1就较小，而电阻R2就较大；反正，当触摸点与第二电极较近时，则电阻R1就较大，而电阻R2就较小。因此，本实用新型通过对电阻R1和R2的检测就可以确定触摸点在该感应单元上的位置。在本实用新型的实施例中，可通过多种方式检测电阻R1和R2，例如可通过检测第一电极和第二电极的电流检测值、自电容检测值、电平信号检测值和电荷变化量中的一种或多种，从而根据这些检测值获得电阻R1和R2。另外，在本实用新型的实施例中，检测可在充电时进行（即获得第一充电检测值和第二充电检测值），也可在放电时进行（即获得第一放电检测值和第二放电检测值）。此外，在充电和放电时进行的检测可以采用多种方式。但是需要说明的是，充电、放电或者检测中至少有一个步骤是对第一电极和第二电极进行的，这样才能够获得反应第一电阻和第二电阻之间差值的两个检测值，即第一检测值和第二检测值。也就是说，在充电、放电或检测时需要有电流经过第一电阻和第二电阻，这样检测到的第一检测值和第二检测值才能够反应第一电阻和第二电阻之间的差值。在本实用新型的实施例中，通常需要充两次电（包括同时对第一电极和第二电极充电的情况），以及两次检测。在一些实施例中，还可能会进行两次放电。在以下的实施例中均是进行两次充电及两次检测，在以下的实施例中不再赘述。在此需要说明的是，进行两次充电及两次检测仅是本实用新型实施例的一种方案，算法相对比较简单。然而本领域技术人员也可根据上述思想增加充电及检测的次数，例如可进行三次充电和检测，之后根据第一次的充电检测值和第二次的充电检测值计算第一电阻，再根据第一次的充电检测值和第三次的充电检测值计算第二电阻。 The embodiment of the utility model proposes a novel self-capacitance detection method. When the sensing unit is touched, the touch point can divide the sensing unit into two resistors. Determine the position of the touch point on the sensing unit. As shown in FIG. 3 , it is a schematic diagram of the detection principle of the touch device according to the embodiment of the present invention. When a finger touches the sensing unit, it is equivalent to dividing the sensing unit into two resistors, and the resistance of the two resistors is related to the position of the touch point. For example, as shown in the figure, when the touch point is closer to the first electrode, the resistor R1 is smaller and the resistor R2 is larger; anyway, when the touch point is closer to the second electrode, the resistor R1 is smaller Large, and the resistor R2 is small. Therefore, the utility model can determine the position of the touch point on the sensing unit by detecting the resistors R1 and R2. In the embodiment of the present utility model, the resistors R1 and R2 can be detected in various ways, for example, by detecting the current detection value, self-capacitance detection value, level signal detection value and charge change amount of the first electrode and the second electrode One or more of them, so that the resistors R1 and R2 are obtained according to these detection values. In addition, in the embodiment of the present utility model, the detection can be carried out during charging (that is, obtaining the first charging detection value and the second charging detection value), and can also be carried out during discharging (that is, obtaining the first discharging detection value and the second discharge detection value). In addition, detection during charging and discharging can be performed in various ways. However, it should be noted that at least one step in charging, discharging or detection is performed on the first electrode and the second electrode, so that two detection values reflecting the difference between the first resistance and the second resistance can be obtained, That is, the first detected value and the second detected value. That is to say, when charging, discharging or detecting, a current needs to pass through the first resistance and the second resistance, so that the detected first detection value and the second detection value can reflect the difference between the first resistance and the second resistance value. In the embodiment of the present utility model, charging twice (including charging the first electrode and the second electrode at the same time) and two detections are usually required. In some embodiments, two discharges may also be performed. In the following embodiments, charging and detection are performed twice, which will not be repeated in the following embodiments. It should be noted here that performing two chargings and two detections is only a scheme of the embodiment of the present invention, and the algorithm is relatively simple. However, those skilled in the art can also increase the number of times of charging and detection according to the above ideas, for example, three charging and detection can be performed, and then the first resistance is calculated according to the first charging detection value and the second charging detection value, and then according to the second charging detection value The first charge detection value and the third charge detection value are used to calculate the second resistance. the

具体地，本实用新型包括但不限于以下几种测量方式进行检测： Specifically, the utility model includes but is not limited to the following measurement methods for detection:

1、先向感应单元的第一电极和第二电极施加电平信号以对自电容充电（如果该感应单元被触摸则就会产生自电容）；接着从第一电极和/或第二电极进行充电检测以获得第一充电检测值和第二充电检测值。在该实施例中，由于充电是从第一电极和第二电极进行的，因此对于检测来说既可以从第一电极进行检测，也可以从第二电极进行检测，或者也可从第一电极和第二电极分别进行检测。还需要说明的是，在该实施例中，对第一电极和第二电极的充电可同时进行，也可分别进行，例如在第一电极和第二电极同时施加相同的电平信号以对自电容进行充电，在其他实施例中，第一电极和第二电极施加的电平信号也可以不同；或者，也可以先在第一电极上施加一个电平信号，之后再在第二电极上施加同一个电平信号或另一个电平信号。同样地，进行检测时既可以同时进行，也可分别进行。在以下实施例中，充电、放电或检测均可同时进 行，或者分别进行，在此不再赘述。 1. First apply a level signal to the first electrode and the second electrode of the sensing unit to charge the self-capacitance (if the sensing unit is touched, self-capacitance will be generated); then proceed from the first electrode and/or the second electrode Charge detection to obtain a first charge detection value and a second charge detection value. In this embodiment, since the charging is performed from the first electrode and the second electrode, the detection can be performed from the first electrode, the second electrode, or the first electrode. and the second electrode are detected separately. It should also be noted that in this embodiment, the charging of the first electrode and the second electrode can be carried out simultaneously or separately, for example, the same level signal is applied to the first electrode and the second electrode at the same time to charge the self In other embodiments, the level signals applied to the first electrode and the second electrode can also be different; or, a level signal can be applied to the first electrode first, and then applied to the second electrode The same level signal or another level signal. Likewise, detection may be performed simultaneously or separately. In the following embodiments, charging, discharging, or detection can be performed simultaneously, or separately, and will not be repeated here. the

2、向所述感应单元的第一电极或第二电极分别两次施加电平信号以对所述自电容进行两次充电；接着在每次充电之后从所述第一电极和/或第二电极进行充电检测以获得所述第一充电检测值和第二充电检测值。在该实施例中，由于充电是从第一电极或第二电极进行的，因此在检测时需要从第一电极和第二电极分别进行检测，其中，检测可同时进行，也可分别进行。此外，在本实用新型的实施例中，还可以在第一电极进行两次充电，并从第一电极进行两次检测，或者，从第二电极进行两次充电，在第二电极进行两次检测。只要是，在两次充电时，分别将另一个电极接地或接高阻以改变另一个电极的状态。例如当向感应单元的第一电极分别两次施加电平信号以对自电容进行两次充电时，其中，两次充电中的一次将所述第二电极接地，另一次将所述第二电极接为高阻；当向感应单元的第二电极分别两次施加电平信号以对自电容进行两次充电时，两次充电中的一次将所述第一电极接地，另一次将所述第一电极接为高阻。这样即使是在第一电极进行了两次充电，由于第二电极状态的改变，也能够在第一电极进行两次检测，以获得能够反应第一电阻R1和第二电阻R2之间比例关系的第一检测值和第二检测值。 2. Apply a level signal twice to the first electrode or the second electrode of the sensing unit to charge the self-capacitance twice; The electrodes perform charge detection to obtain the first charge detection value and the second charge detection value. In this embodiment, since the charging is performed from the first electrode or the second electrode, the detection needs to be performed separately from the first electrode and the second electrode, wherein the detection can be performed simultaneously or separately. In addition, in the embodiment of the present invention, it is also possible to charge twice at the first electrode and perform two detections from the first electrode, or to charge twice from the second electrode and perform two detections at the second electrode detection. As long as it is, when charging twice, the other electrode is grounded or connected to high resistance to change the state of the other electrode. For example, when a level signal is applied twice to the first electrode of the sensing unit to charge the self-capacitance twice, wherein, one of the two charges connects the second electrode to ground, and the other charges the second electrode to the ground. Connected to high resistance; when applying a level signal to the second electrode of the sensing unit twice to charge the self-capacitance twice, one of the two charges will ground the first electrode, and the other will connect the first electrode to the ground. One electrode is connected to high resistance. In this way, even if the first electrode is charged twice, due to the change of the state of the second electrode, two detections can be performed on the first electrode, so as to obtain a value that can reflect the proportional relationship between the first resistance R1 and the second resistance R2. The first detection value and the second detection value. the

3、向感应单元的第一电极和第二电极施加电平信号以对自电容充电；接着控制第一电极和/或第二电极接地以对自电容放电；之后从第一电极和/或第二电极进行放电检测以获得所述第一放电检测值和第二放电检测值。在该实施例中，由于对自电容充电是从第一电极和第二电极进行的，因此放电或检测就可从第一电极和/或第二电极进行。具体地，例如可同时向第一电极和第二电极施加电平信号以对自电容进行充电，或者也可不同时施加。在放电时两次放电可均将第一电极接地，或者均将第二电极接地。 3. Apply a level signal to the first electrode and the second electrode of the sensing unit to charge the self-capacitance; then control the first electrode and/or the second electrode to be grounded to discharge the self-capacity; then from the first electrode and/or the second electrode The two electrodes perform discharge detection to obtain the first discharge detection value and the second discharge detection value. In this embodiment, since charging of the self-capacitance is performed from the first electrode and the second electrode, discharging or detection can be performed from the first electrode and/or the second electrode. Specifically, for example, level signals may be applied to the first electrode and the second electrode at the same time to charge the self-capacitance, or may not be applied at the same time. When discharging, the two discharges may both ground the first electrode, or both ground the second electrode. the

4、向感应单元的第一电极或第二电极施加电平信号以对自电容充电；接着分别控制第一电极和第二电极接地以对自电容放电；之后分别从第一电极和/或第二电极进行放电检测以获得第一放电检测值和第二放电检测值。在该实施例中，由于对自电容放电是从第一电极和第二电极进行的，因此充电或检测就可从第一电极和/或第二电极进行。在该实施例中，两次充电也可均用第一电极，而将第二电极分别接地或接为高阻。同样地，两次充电也可均用第二电极，而将第一电极分别接地或接为高阻。 4. Apply a level signal to the first electrode or the second electrode of the sensing unit to charge the self-capacitance; then respectively control the first electrode and the second electrode to be grounded to discharge the self-capacity; then respectively from the first electrode and/or the second electrode The two electrodes perform discharge detection to obtain a first discharge detection value and a second discharge detection value. In this embodiment, since the self-capacitance discharge is performed from the first electrode and the second electrode, charging or detection can be performed from the first electrode and/or the second electrode. In this embodiment, the first electrodes can also be used for both charging, and the second electrodes are respectively grounded or connected to high resistance. Similarly, the second electrode can also be used for both charging, and the first electrodes are respectively grounded or connected to high resistance. the

5、向感应单元的第一电极或第二电极施加电平信号以对自电容充电；接着分别控制第一电极或第二电极接地以对自电容放电，之后分别从第一电极和第二电极进行放电检测以获得第一放电检测值和第二放电检测值。在该实施例中，由于对自电容检测是从第一电极和第二电极进行的，因此充电或放电就可从第一电极和/或第二电极进行。在该实施例中，两次充电也可均用第一电极，而将第二电极分别接地或接为高阻。同样地，两次充电也可均用第二电极，而将第一电极分别接地或接为高阻。 5. Apply a level signal to the first electrode or the second electrode of the sensing unit to charge the self-capacitance; then respectively control the first electrode or the second electrode to be grounded to discharge the self-capacity, and then respectively from the first electrode and the second electrode A discharge detection is performed to obtain a first discharge detection value and a second discharge detection value. In this embodiment, since the self-capacitance detection is performed from the first electrode and the second electrode, charging or discharging can be performed from the first electrode and/or the second electrode. In this embodiment, the first electrodes can also be used for both charging, and the second electrodes are respectively grounded or connected to high resistance. Similarly, the second electrode can also be used for both charging, and the first electrodes are respectively grounded or connected to high resistance. the

或者，在上述实施例的基础之上，还可以在充电时进行一次检测以获得第一充电检测值，在放电时进行第二次检测以获得第二放电检测值，再根据第一充电检测值和第二放电检测值获得第一电阻和第二电阻之间的比例关系。 Or, on the basis of the above-mentioned embodiments, it is also possible to perform a detection during charging to obtain the first detection value of charging, and perform a second detection during discharge to obtain the second detection value of discharge, and then according to the first detection value of charging and the second discharge detection value to obtain a proportional relationship between the first resistance and the second resistance. the

需要说明的是，在本实用新型的实施例中，上述第一电极和第二电极的功能相同，且二者可以互换，因此在上述实施例中，既可以从第一电极检测也可以从第二电极检测，只要能满足在充电、放电或检测时需要有电流经过第一电阻和第二电阻这一要求即可。 It should be noted that, in the embodiment of the present utility model, the functions of the above-mentioned first electrode and the second electrode are the same, and the two can be interchanged. The detection of the second electrode only needs to meet the requirement that a current needs to pass through the first resistor and the second resistor during charging, discharging or detection. the

从上述描述中可以看出，对于本实用新型的上述充电及检测方式有很多种变化，但本实用新型的核心就是根据第一电阻和第二电阻之间的关系，例如比例关系或者其他关系来确定触摸点的位置。进一步地，该第一电阻和第二电阻之间的关系需要通过自电容的充电和/或放电来检测。如果感应单元没有被触摸，则就不会与手产生自电容，因此检测到自电容的数据会很小，不满足触摸的判断条件，对于此本实用新型实施例中会不断扫描，等待手指触摸到感应单元之后才开始计算，在此不再赘述。 It can be seen from the above description that there are many changes to the above-mentioned charging and detection methods of the present invention, but the core of the present invention is based on the relationship between the first resistor and the second resistor, such as a proportional relationship or other relationships. Determine the location of the touch point. Further, the relationship between the first resistance and the second resistance needs to be detected through charging and/or discharging of the self-capacitance. If the sensing unit is not touched, it will not generate self-capacitance with the hand, so the data detected from the self-capacitance will be very small, which does not meet the judgment conditions of touch. For this, in the embodiment of the utility model, it will continue to scan and wait for the finger to touch The calculation starts after the sensing unit is reached, and details will not be described here. the

在本实用新型的实施例中，可以以扫描的方式依次向多个感应单元施加相应的电压，同时在检测时也可以以扫描的方式依次进行检测。 In the embodiment of the present invention, the corresponding voltage can be applied to the plurality of sensing units sequentially in a scanning manner, and at the same time, detection can also be performed in a scanning manner during detection. the

另外还需要说明的是，上述检测方式仅为本实用新型的一些优选方式，本领域技术人员还可根据上述思想进行扩展或修改，这些均应包含在本实用新型的保护范围之内。 In addition, it should be noted that the above-mentioned detection methods are only some preferred methods of the present invention, and those skilled in the art can also make extensions or modifications based on the above ideas, which should be included in the protection scope of the present invention. the

如图4所示，为本实用新型实施例的触摸检测方法流程图，该流程图结合图3所示的原理图一同进行说明。该方法包括以下步骤： As shown in FIG. 4 , it is a flow chart of a touch detection method according to an embodiment of the present invention, and the flow chart will be described together with the schematic diagram shown in FIG. 3 . The method includes the following steps:

步骤S401，向感应单元的两端施加电平信号，即向感应单元的第一电极和/或第二电极施加电平信号。在该实施例中，可向第一电极和第二电极施加相同的电平信号，也可施加不同的电平信号。在其他实施例中，也可仅从第一电极或第二电极进行充电两次，或者第一次从第一电极充电第二次从第二电极充电，或者第一次从第二电极充电第二次从第一电极充电。 Step S401, applying a level signal to both ends of the sensing unit, that is, applying a level signal to the first electrode and/or the second electrode of the sensing unit. In this embodiment, the same level signal may be applied to the first electrode and the second electrode, or different level signals may be applied. In other embodiments, it is also possible to charge only twice from the first electrode or the second electrode, or charge from the first electrode for the first time and charge from the second electrode for the second time, or charge the second electrode from the second electrode for the first time. Second charge from the first electrode. the

如果此时该感应单元被手指或其他物体触摸，则该感应单元将会产生自电容C1（参照图3），通过施加的电平信号就可对自电容进行充电。在本实用新型的实施例中，通过对自电容的充电，可以提高自电容的检测精度。 If the sensing unit is touched by a finger or other objects at this time, the sensing unit will generate a self-capacitance C1 (refer to FIG. 3 ), and the self-capacitance can be charged by applying a level signal. In the embodiment of the present invention, the detection accuracy of the self-capacitance can be improved by charging the self-capacitance. the

并且，所述触摸屏控制芯片包括一个或两个电容检测器件CTS。 Moreover, the touch screen control chip includes one or two capacitance detection devices CTS. the

需要说明的是，如果向感应单元的两端同时施加电平信号的话，则需要相应的两个电容检测器件CTS同时从感应单元的两端进行检测。而如果分别向两端时间的话，则仅需要一个电容检测器件CTS即可。在本实用新型的一个实施例中，第一检测值和第二检测值可以为从第一电极和/或第二电极检测到的电容电荷变化量ΔQ1和ΔQ2。通过ΔQ1与ΔQ2，即检测到得自电容变化量，就可以算出R1与R2的比例，由于图形的规则线性关系，则可以算出触摸点所在的横坐标的位置，及自电容C1所在的位置。 It should be noted that, if a level signal is applied to both ends of the sensing unit at the same time, two corresponding capacitance detection devices CTS are required to simultaneously detect from both ends of the sensing unit. However, if the two ends are clocked separately, only one capacitance detection device CTS is needed. In an embodiment of the present invention, the first detected value and the second detected value may be the capacitive charge variations ΔQ1 and ΔQ2 detected from the first electrode and/or the second electrode. Through ΔQ1 and ΔQ2, that is, the detection of the capacitance change, the ratio of R1 to R2 can be calculated. Due to the regular linear relationship of the graph, the position of the abscissa of the touch point and the position of the self-capacitance C1 can be calculated. the

步骤S402，从感应单元的两端对感应单元进行检测，以获得第一检测值和第二检测值。在该实施例中，检测可在充电时进行，也可在放电时进行。在上述例子中，第一检测值和第二检测值分别为ΔQ1和ΔQ2。以下以第一检测值和第二检测值为电荷变化量为例进行描述，但是能够反应电阻R1和R2关系的其他检测值，例如电平信号、 电流等也均可采用。在本实用新型的实施例中，既可以同时检测，也可以分别检测。 Step S402, detecting the sensing unit from both ends of the sensing unit to obtain a first detection value and a second detection value. In this embodiment, detection can be performed during charging or discharging. In the above example, the first detection value and the second detection value are ΔQ1 and ΔQ2, respectively. In the following, the first detection value and the second detection value are described as an example of charge variation, but other detection values that can reflect the relationship between resistors R1 and R2, such as level signals, currents, etc., can also be used. In the embodiment of the present invention, it can be detected simultaneously or separately. the

在本实用新型的一个实施例中，如果进行同时检测，则需要两个自电容触摸屏控制芯片同时对第一电极和第二电极进行检测。 In one embodiment of the present invention, if simultaneous detection is performed, two self-capacitance touch screen control chips are required to simultaneously detect the first electrode and the second electrode. the

在本实用新型的另一个实施例中，也可采用一个自电容触摸屏控制芯片进行检测，参照步骤S401中，在通过第一电极对自电容C1充满之后，即该自电容触摸屏控制芯片通过第一电极对自电容C1进行检测。接着再通过第二电极对自电容C2充电，接着该自电容触摸屏控制芯片再通过第二电极对自电容C1进行检测。 In another embodiment of the present invention, a self-capacitance touch screen control chip can also be used for detection. Referring to step S401, after the self-capacitance C1 is fully charged through the first electrode, that is, the self-capacitance touch screen control chip passes through the first electrode. The electrodes detect the self-capacitance C1. Then the self-capacitance C2 is charged through the second electrode, and then the self-capacitance touch screen control chip detects the self-capacitance C1 through the second electrode. the

由于自电容触摸屏控制芯片扫描该感应单元时采用的相位和电平信号均一致，因此对于同一个自电容C1来说充电时的电荷就等于它们电阻的反比。假设，从感应单元的第一电极和第二电极对感应单元检测获得的电荷变化量分别是ΔQ1与ΔQ2。在本实用新型的实施例中，自电容触摸屏控制芯片可为目前已知的自电容触摸屏控制芯片。在本实用新型的一个实施例中，如果采用两个自电容触摸屏控制芯片的话，则由于两个自电容触摸屏控制芯片可工艺多个器件，因此不会增大芯片的整体功耗。 Since the self-capacitance touch screen control chip uses the same phase and level signals when scanning the sensing unit, the charge when charging the same self-capacitance C1 is equal to the inverse ratio of their resistances. Assume that the amount of change in charge detected by the sensing unit from the first electrode and the second electrode of the sensing unit is ΔQ1 and ΔQ2 respectively. In an embodiment of the present invention, the self-capacitance touch screen control chip may be a currently known self-capacitance touch screen control chip. In one embodiment of the present invention, if two self-capacitance touch screen control chips are used, since the two self-capacitance touch screen control chips can process multiple devices, the overall power consumption of the chip will not be increased. the

步骤S403，根据第一检测值和第二检测值判断该感应单元是否被触摸。具体地，在本实用新型的一个实施例中，可通过判断电荷变化量ΔQ1与ΔQ2是否大于阈值来确定是否被触摸。当然，在本实用新型的其他实施例中，还可设置其他判断方式，例如判断电荷变化量ΔQ1与ΔQ2是否小于阈值，如果小于，则判断感应单元被触摸。同样地，该阈值也需要根据触摸屏的大小和类型，感应单元的尺寸确定。 Step S403, judging whether the sensing unit is touched according to the first detection value and the second detection value. Specifically, in an embodiment of the present invention, it can be determined whether it is touched by judging whether the charge variation ΔQ1 and ΔQ2 are greater than a threshold. Of course, in other embodiments of the present invention, other judging methods can also be set, such as judging whether the charge change amounts ΔQ1 and ΔQ2 are smaller than a threshold, and if so, judging that the sensing unit is touched. Similarly, the threshold also needs to be determined according to the size and type of the touch screen and the size of the sensing unit. the

步骤S404，如果判断该感应单元被触摸，则此时进一步计算相应的感应单元中所述第一电极至所述自电容的第一电阻与所述第二电极至所述自电容的第二电阻之间的比例关系。并根据第一电阻和所述第二电阻之间的比例关系确定触摸物体（例如手指）的触摸位置。在本实用新型的实施例中，第一电阻和所述第二电阻之间的比例关系根据在对自电容充电/放电时，从第一电极和/或第二电极进行检测获得的第一检测值和第二检测值之间的比例关系计算得到。同上，C1所在的感应单元上的坐标即为ΔQ2/(ΔQ1+ΔQ2)。 Step S404, if it is determined that the sensing unit is touched, further calculate the first resistance from the first electrode to the self-capacitance and the second resistance from the second electrode to the self-capacitance in the corresponding sensing unit The proportional relationship between them. And determine the touch position of the touch object (such as a finger) according to the proportional relationship between the first resistance and the second resistance. In an embodiment of the present invention, the proportional relationship between the first resistance and the second resistance is based on the first detection obtained from the detection of the first electrode and/or the second electrode when charging/discharging the self-capacitance The proportional relationship between the value and the second detection value is calculated. As above, the coordinate on the sensing unit where C1 is located is ΔQ2/(ΔQ1+ΔQ2). the

在本实用新型的实施例中，如果感应单元为门形感应单元或L形感应单元，则通过第一电阻和第二电阻之间的比值就可确定在触摸屏上的触摸位置，以下将结合具体的例子进行详述。但在本实用新型的其他实施例中，如果感应单元为矩形感应单元或蛇形（但整体上看相当于矩形）感应单元，触摸位置为在第一方向上的触摸位置，则步骤S404只能计算出在触摸屏第一方向上的触摸位置，该第一方向可以是感应单元的长度方向（例如触摸屏的水平方向）。 In an embodiment of the present invention, if the sensing unit is a door-shaped sensing unit or an L-shaped sensing unit, the touch position on the touch screen can be determined by the ratio between the first resistance and the second resistance, and the following will be combined with specific Examples are described in detail. However, in other embodiments of the present utility model, if the sensing unit is a rectangular sensing unit or a snake-shaped (but generally equivalent to a rectangle) sensing unit, and the touch position is the touch position in the first direction, then step S404 can only The touch position in the first direction of the touch screen is calculated, and the first direction may be the length direction of the sensing unit (for example, the horizontal direction of the touch screen). the

如果感应单元为矩形感应单元或蛇形（但整体上看相当于矩形）感应单元，则还需要根据感应单元的位置确定在第二方向上的触摸位置。在本实用新型的一个实施例中，第一方向为感应单元的长度方向，第二方向为垂直于感应单元的方向，感应单元水平设置或垂直设置。 If the sensing unit is a rectangular sensing unit or a snake-shaped (but generally equivalent to a rectangular) sensing unit, it is also necessary to determine the touch position in the second direction according to the position of the sensing unit. In one embodiment of the present invention, the first direction is the length direction of the sensing unit, the second direction is the direction perpendicular to the sensing unit, and the sensing unit is arranged horizontally or vertically. the

具体地，可采用质心算法计算触摸点在第二方向上的触摸位置，以下对质心算法 进行简单介绍。 Specifically, the centroid algorithm can be used to calculate the touch position of the touch point in the second direction, and the centroid algorithm is briefly introduced below. the

在滑条和触摸板应用中，经常有必要在具体感应单元的本质间距以上确定出手指（或其他电容性物体）的位置。手指在滑条或触摸板上的接触面板通常大于任何个感应单元。为了采用一个中心来计算触摸后的位置，对这个阵列进行扫描以验证所给定的传感器位置是有效的，对于一定数量的相邻感应单元信号的要求是要大于预设触摸阈值。在找到最为强烈的信号后，此信号和那些大于触摸阈值的临近信号均用于计算中心： In slider and touchpad applications, it is often necessary to determine the position of a finger (or other capacitive object) beyond the intrinsic pitch of a particular sensing element. The contact surface of a finger on a slider or touchpad is usually larger than any number of sensing elements. In order to use a center to calculate the post-touch position, the array is scanned to verify that a given sensor position is valid, and the requirement for a certain number of adjacent sensing unit signals to be greater than a preset touch threshold. After finding the strongest signal, this signal and those neighboring signals greater than the touch threshold are used to calculate the center:

${\mathrm{<span><span>N</span>N</span>}}_{\mathrm{<span><span>Cent</span>Cent</span>}}<span><span>=</span>=</span>\frac{{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}<span><span>-</span>-</span>\mathrm{<span><span>1</span>1</span>}}<span><span>(</span>(</span>\mathrm{<span><span>i</span>i</span>}<span><span>-</span>-</span>\mathrm{<span><span>1</span>1</span>}<span><span>)</span>)</span><span><span>+</span>+</span>{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}}\mathrm{<span><span>i</span>i</span>}<span><span>+</span>+</span>{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}<span><span>+</span>+</span>\mathrm{<span><span>1</span>1</span>}}<span><span>(</span>(</span>\mathrm{<span><span>i</span>i</span>}<span><span>+</span>+</span>\mathrm{<span><span>1</span>1</span>}<span><span>)</span>)</span>}{{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}<span><span>-</span>-</span>\mathrm{<span><span>1</span>1</span>}}<span><span>+</span>+</span>{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}}<span><span>+</span>+</span>{\mathrm{<span><span>n</span>no</span>}}_{\mathrm{<span><span>i</span>i</span>}<span><span>+</span>+</span>\mathrm{<span><span>1</span>1</span>}}}$

其中，Ncent为中心处感应单元的标号，n为检测到被触摸的感应单元的个数，i为被触摸感应单元的序号，其中i大于等于2。 Wherein, Ncent is the label of the sensing unit at the center, n is the number of sensing units that are detected to be touched, and i is the serial number of the sensing unit that is touched, wherein i is greater than or equal to 2. the

例如，当手指触摸在第一条通道，其电容变化量为y1，第二条通道上的电容变化量为y2和第三条通道上的电容变化量为y3时。其中第二通道y2电容变化量最大。Y坐标就可以算是： For example, when a finger touches the first channel, its capacitance variation is y1, the capacitance variation on the second channel is y2, and the capacitance variation on the third channel is y3. Among them, the capacitance variation of the second channel y2 is the largest. The Y coordinate can be regarded as:

本实用新型实施例根据上述思想提出了一种触控装置。该触控装置包括基板、多个不相交的感应单元。在本实用新型的实施例中，不相交的感应单元之间可以相互平行，或者不相交的感应单元之间也可以部分地平行。其中，多个感应单元形成在基板之上，且多个感应单元的每个均具有相对设置的第一电极和第二电极。如图5所示，为本实用新型一个实施例的触控装置示意图。该触控装置包括基板100、多个不相交的感应单元200和触摸屏控制芯片300。在本实用新型的实施例中，基板100可为单层基板。其中，如图所示，该触控装置采用矩形的感应单元200，该矩形感应单元200具有较高的长宽比，且感应单元200具有相对设置的第一电极210和第二电极220。采用平行的矩形感应单元200可以降低装置的结构复杂度，从而可以在保证检测精度的基础上降低制造成本。但是在此需要说明的是，对于多个感应单元来说，并不限制其为图5的结构，该感应单元200还可采用其他的结构，例如感应单元的一部分或全部具有一定的弧度等，这些均可应用在本实用新型中。触摸屏控制芯片300分别与多个感应单元200的第一电极210和第二电极220相连。且触摸屏控制芯片300向多个感应单元200的第一电极210和/或第二电极220施加电平信号，使得该电平信号能够在感应单元200被触摸时向感应单元200产生的自电容充电，且触摸屏控制芯片300在检测到多个感应单元200中一个或部分被触摸时，计算相应的感应单元中第一电极210至自 电容的第一电阻与第二电极220至自电容的第二电阻之间的比例关系，并根据第一电阻和第二电阻之间的比例关系确定在第一方向上的触摸位置，以及根据被触摸的感应单元200的位置确定在第二方向上的触摸位置。 The embodiment of the utility model proposes a touch device based on the above idea. The touch device includes a substrate and a plurality of disjoint sensing units. In an embodiment of the present invention, the disjoint sensing units may be parallel to each other, or the disjoint sensing units may also be partially parallel. Wherein, a plurality of sensing units are formed on the substrate, and each of the plurality of sensing units has a first electrode and a second electrode disposed opposite to each other. As shown in FIG. 5 , it is a schematic diagram of a touch device according to an embodiment of the present invention. The touch device includes asubstrate 100 , a plurality ofdisjoint sensing units 200 and a touchscreen control chip 300 . In an embodiment of the present invention, thesubstrate 100 may be a single-layer substrate. Wherein, as shown in the figure, the touch device adopts arectangular sensing unit 200 with a high aspect ratio, and thesensing unit 200 has afirst electrode 210 and asecond electrode 220 disposed opposite to each other. The use of parallelrectangular sensing units 200 can reduce the structural complexity of the device, thereby reducing manufacturing costs while ensuring detection accuracy. But what needs to be explained here is that for multiple sensing units, it is not limited to the structure shown in FIG. These all can be applied in the utility model. The touchscreen control chip 300 is respectively connected to thefirst electrodes 210 and thesecond electrodes 220 of the plurality ofsensing units 200 . And the touchscreen control chip 300 applies a level signal to thefirst electrode 210 and/or thesecond electrode 220 of the plurality of sensingunits 200, so that the level signal can charge the self-capacitance generated by thesensing unit 200 when thesensing unit 200 is touched. , and when the touchscreen control chip 300 detects that one or part of a plurality of sensingunits 200 is touched, it calculates the first resistance from thefirst electrode 210 to the self-capacitance and the second resistance from thesecond electrode 220 to the self-capacitance in the corresponding sensing unit. The proportional relationship between the resistances, and determine the touch position in the first direction according to the proportional relationship between the first resistance and the second resistance, and determine the touch position in the second direction according to the position of the touchedsensing unit 200 . the

具体地，第一电阻和第二电阻之间的比例关系根据在对自电容充电/放电时，从第一电极和/或第二电极进行检测获得的第一检测值和第二检测值之间的比例关系计算得到，如上所述对第一电极和第二电极的充电、放电或检测可同时进行，也可分开进行。当触摸屏控制芯片300根据第一检测值和第二检测值确定对应的感应单元被触摸时，则触摸屏控制芯片300根据第一检测值和第二检测值计算第一电阻和第二电阻的比例关系，从而进一步判断在第一方向上的触摸位置，并根据对应的感应单元200的位置确定在第二方向上的触摸位置。最后触摸屏控制芯片300根据第一方向上的触摸位置和第二方向上的触摸位置就可确定触摸点在触摸屏上的位置。在此还需要说明的是，在本实用新型的实施例中对于对感应单元的充电和放电次序来说没有限制，例如在一个实施例中，可以以扫描的方式对所有的感应单元200依次进行充电，接着再依次地对其进行放电检测；在另一个实施例中，可以逐个对感应单元200进行充电和放电，例如对一个感应单元200充电之后，接着就对其进行放电检测，对该感应单元200处理完成之后，再对下一个感应单元200进行处理。在本实用新型的一个实施例中，触摸屏控制芯片300向感应单元200的第一电极210和第二电极220施加电平信号以对自电容充电，触摸屏控制芯片300从第一电极210和/或第二电极220进行充电检测以获得第一充电检测值和第二充电检测值。 Specifically, the proportional relationship between the first resistance and the second resistance is based on the relationship between the first detection value and the second detection value obtained from the detection of the first electrode and/or the second electrode when charging/discharging the self-capacitance The proportional relationship is calculated. As mentioned above, the charging, discharging or detection of the first electrode and the second electrode can be performed simultaneously or separately. When the touchscreen control chip 300 determines that the corresponding sensing unit is touched according to the first detection value and the second detection value, the touchscreen control chip 300 calculates the proportional relationship between the first resistance and the second resistance according to the first detection value and the second detection value , so as to further determine the touch position in the first direction, and determine the touch position in the second direction according to the position of thecorresponding sensing unit 200 . Finally, the touchscreen control chip 300 can determine the position of the touch point on the touch screen according to the touch position in the first direction and the touch position in the second direction. It should also be noted here that there is no limitation on the charging and discharging sequence of the sensing units in this embodiment of the present invention.

The pins are connected. the

在本实用新型的实施例中，所谓相互嵌套是指外侧的感应单元部分地包围内侧的感应单元，例如如图7a所示，这样能够在保证精度的同时达到较大的覆盖率，并且降低运算的复杂度，提高触摸屏的响应速度。当然本领域技术人员还可根据图7a的思想采用其他相互嵌套的方式排列感应单元。在本实用新型的一个实施例中，每个感应单元200的第三部分250与其他感应单元200的第三部分250平行，每个感应单元200的第四部分260与其他感应单元200的第四部分260平行，每个感应单元200的第五部分270与其他感应单元200的第五部分270平行。在本实用新型的一个实施例中，感应单元200的第三部分250、第四部分260和第五部分270中至少一个为矩形，优选地，第三部分250、第四部分260和第五部分270均为矩形。在该实施例中，由于矩形结构图形规则，因此在手指横向或纵向移动时线性度好，此外，两个矩形结构之间的间距相同，便于计算，从而提高计算速度。 In the embodiment of the present utility model, the so-called mutual nesting refers to that the sensing unit on the outside partially surrounds the sensing unit on the inside, such as shown in FIG. The complexity of the calculation improves the response speed of the touch screen. Of course, those skilled in the art can also arrange the sensing units in other mutual nesting manners according to the concept of FIG. 7a. In one embodiment of the present utility model, thethird part 250 of eachsensing unit 200 is parallel to thethird part 250 ofother sensing units 200, and thefourth part 260 of eachsensing unit 200 is parallel to thefourth part 260 ofother sensing units 200. Thesections 260 are parallel, and thefifth section 270 of eachsensing unit 200 is parallel to thefifth sections 270 ofother sensing units 200 . In one embodiment of the present utility model, at least one of thethird part 250, thefourth part 260 and thefifth part 270 of thesensing unit 200 is rectangular, preferably, thethird part 250, thefourth part 260 and thefifth part 270 are all rectangles. In this embodiment, due to the regular pattern of the rectangular structure, the linearity is good when the finger moves horizontally or vertically. In addition, the distance between the two rectangular structures is the same, which is convenient for calculation, thereby improving the calculation speed. the

在本实用新型的一个实施例中，每个感应单元200的第四部分260与第五部分270长度相等。 In an embodiment of the present invention, the length of thefourth part 260 and thefifth part 270 of eachinduction unit 200 are equal. the

在本实用新型的一个实施例中，基板100为矩形，第一边110和第二边120之间相互垂直，且第四部分260和第三部分250之间相互垂直，第五部分270和第三部分250之间相互垂直。 In one embodiment of the present utility model, thesubstrate 100 is rectangular, thefirst side 110 and thesecond side 120 are perpendicular to each other, and thefourth part 260 and thethird part 250 are perpendicular to each other, thefifth part 270 and the The threeparts 250 are perpendicular to each other. the

在本实用新型的一个实施例中，相邻两个感应单元200的第三部分250之间的间距相等，相邻两个感应单元200的第四部分260之间的间距相等，相邻两个感应单元200的第五部分270之间的间距相等。这样就可以通过多个感应单元200对触摸屏的第一边110和第二边120均匀划分，从而提高运算速度。当然在本实用新型的其他实施例中，相邻两个感应单元200的第三部分250之间的间距也可不相等，或者，相邻两个感应单元200的第四部分260之间的间距也可不相等，如图7b所示。例如，由于用户往往触摸触摸屏的中心部位，因此可以将触摸屏中心部位的感应单元之间的间距减小，从而提高中心部位的检测精度。 In one embodiment of the present utility model, the spacing between thethird parts 250 of twoadjacent sensing units 200 is equal, the spacing between thefourth parts 260 of twoadjacent sensing units 200 is equal, and the spacing between thefourth parts 260 of twoadjacent sensing units 200 is equal. The distances between thefifth parts 270 of thesensing unit 200 are equal. In this way, thefirst side 110 and thesecond side 120 of the touch screen can be evenly divided by the plurality of sensingunits 200, thereby improving the operation speed. Of course, in other embodiments of the present utility model, the spacing between thethird parts 250 of twoadjacent sensing units 200 may also be unequal, or the spacing between thefourth parts 260 of twoadjacent sensing units 200 may also be equal. may not be equal, as shown in Figure 7b. For example, since the user often touches the center of the touch screen, the distance between the sensing units at the center of the touch screen can be reduced, thereby improving the detection accuracy of the center. the

在本实用新型的一个实施例中，多个感应单元200相对于基板100的中心轴Y对称，如图7a所示，中心轴Y垂直于第三部分250，从而更有利于提高精度。 In one embodiment of the present invention, themultiple sensing units 200 are symmetrical with respect to the central axis Y of thesubstrate 100, as shown in FIG. the

如图7a所示，在该实施例中，感应单元200的第一电极210和第二电极220均位于基板100的第一边110上。在该实施例中，检测到在感应单元上的触摸位置之后，即可获得在触摸屏之上的触摸位置。 As shown in FIG. 7 a , in this embodiment, both thefirst electrode 210 and thesecond electrode 220 of thesensing unit 200 are located on thefirst side 110 of thesubstrate 100 . In this embodiment, after the touch position on the sensing unit is detected, the touch position on the touch screen can be obtained. the

需要说明的是，上述图7a为本实用新型较优的实施例，其能够获得较大的覆盖率， 但是本实用新型的其他实施例可对图7a进行一些等同的变化，例如第四部分260和第五部分270可以是不平行的。 It should be noted that the above-mentioned Fig. 7a is a preferred embodiment of the utility model, which can obtain greater coverage, but other embodiments of the utility model can carry out some equivalent changes to Fig. 7a, for example, thefourth part 260 andfifth section 270 may be non-parallel. the

本实用新型实施例中的感应单元采用类似门形的结构，不仅结构简单，便于制作，所有引线都在同一边，设计方便，减少银浆成本并且制作容易，对减少生产成本有很大帮助。 The induction unit in the embodiment of the utility model adopts a gate-like structure, which is not only simple in structure, but also easy to manufacture. All the leads are on the same side, which is convenient in design, reduces the cost of silver paste and is easy to manufacture, which is of great help to reduce production costs. the

如图8所示，为本实用新型实施例的感应单元被触摸时的示意图。从图8可知，第一电极为210，第二电极为220，触摸位置接近于第二电极，假设感应单元的长度为10个单位长度，且将感应单元均匀地分为10份，其中，感应单元第三部分250的长度为4个单位长度，感应单元第四部分260和第五部分270的长度为3个单位长度。经过检测，获知第一电阻和第二电阻之比为4:1，即第一电极210至触摸位置的长度（由第一电阻体现）为全部感应单元长度的80%。换句话说，触摸点位于距离第一电极210处8个单位长度的位置，获知，触摸点位于距离第二电极220处2个单位长度的位置。当手指移动时，触摸位置会相应移动，因此通过触摸位置的变换就可判断手指相应的移动轨迹，从而判断用户的输入指令。 As shown in FIG. 8 , it is a schematic diagram when the sensing unit of the embodiment of the present invention is touched. It can be seen from Fig. 8 that the first electrode is 210, the second electrode is 220, and the touch position is close to the second electrode. Assume that the length of the sensing unit is 10 unit lengths, and the sensing unit is evenly divided into 10 parts. The length of thethird part 250 of the unit is 4 unit lengths, and the lengths of thefourth part 260 and thefifth part 270 of the induction unit are 3 unit lengths. After testing, it is known that the ratio of the first resistor to the second resistor is 4:1, that is, the length from thefirst electrode 210 to the touch position (represented by the first resistor) is 80% of the length of the entire sensing unit. In other words, the touch point is located at a distance of 8 unit lengths from thefirst electrode 210 , and it is known that the touch point is located at a distance of 2 unit lengths from thesecond electrode 220 . When the finger moves, the touch position will move accordingly, so the corresponding movement track of the finger can be judged through the transformation of the touch position, so as to judge the user's input instruction. the

从图8的以上例子可以看出，本实用新型的计算方式非常简单，因此能够极大地提高触摸屏检测的反应速度。 It can be seen from the above example in FIG. 8 that the calculation method of the present invention is very simple, so the reaction speed of touch screen detection can be greatly improved. the

更为重要的是，本实用新型通过计算第一电阻和第二电阻之间比例实现触摸位置的确定，因此相对于目前的菱形或三角形设计来说，由于在确定触摸位置时，无需计 算自电容的大小，且自电容的大小不会影响触摸位置的精度，对自电容检测精度的依赖降低，从而提高了测量精度，改善了线性度。此外，由于本实用新型实施例的第五部分270、第六部分280和第七部分290中任意一个均可为形状规则的矩形，因此相对于目前的菱形或三角形等不规则的形状来说，也可以进一步地提高线性度。 More importantly, the utility model realizes the determination of the touch position by calculating the ratio between the first resistance and the second resistance. Therefore, compared with the current rhombus or triangle design, there is no need to calculate the touch position when determining the touch position. The size of the capacitance, and the size of the self-capacitance will not affect the accuracy of the touch position, and the dependence on the detection accuracy of the self-capacitance is reduced, thereby improving the measurement accuracy and improving the linearity. In addition, since any one of thefifth part 270, thesixth part 280 and theseventh part 290 of the embodiment of the present invention can be a regular rectangle, so compared to the current irregular shapes such as rhombus or triangle, It is also possible to further improve the linearity. the

在本实用新型的一个实施例中，每个感应单元的第六部分280与第七部分290长度相等，从而能够提高运算速度。优选地，基板100为矩形，第一边110和第二边120之间相互垂直。第一边110和第二边120相互垂直，不仅使得感应单元设计更加规则，例如使得感应单元的第六部分280和第七部分290之间也相互垂直，从而提高对触摸屏的覆盖率，而且第六部分280和第七部分290之间相互垂直也可以提高检测的线性度。 In an embodiment of the present invention, the length of thesixth part 280 and theseventh part 290 of each induction unit are equal, so as to improve the operation speed. Preferably, thesubstrate 100 is rectangular, and thefirst side 110 and thesecond side 120 are perpendicular to each other. Thefirst side 110 and thesecond side 120 are perpendicular to each other, which not only makes the design of the sensing unit more regular, for example, makes thesixth part 280 and theseventh part 290 of the sensing unit also perpendicular to each other, thereby improving the coverage of the touch screen, and the second The fact that the sixparts 280 and theseventh part 290 are perpendicular to each other can also improve the linearity of detection. the

在本实用新型的一个实施例中，相邻两个感应单元200之间的间距相等，这样就可以通过多个感应单元200对触摸屏的第一边110和第二边120均匀划分，从而提高运算速度，提高计算速度。 In one embodiment of the present utility model, the spacing between twoadjacent sensing units 200 is equal, so that thefirst side 110 and thesecond side 120 of the touch screen can be evenly divided by a plurality of sensingunits 200, thereby improving the calculation efficiency. Speed, to increase calculation speed. the

当然在本实用新型的另一个实施例中，相邻两个感应单元200之间的间距也可以不等，如图9b所示，例如由于用户往往触摸触摸屏的中心部位，因此可以将触摸屏中心部位的感应单元之间的间距减小，从而提高中心部位的检测精度。 Of course, in another embodiment of the present utility model, the distance between twoadjacent sensing units 200 can also be unequal, as shown in Figure 9b, for example, because the user often touches the central part of the touch screen, the central part of the touch screen can be The distance between the sensing units is reduced, thereby improving the detection accuracy of the central part. the

如图9a所示，在该实施例中，感应单元200的第一电极210位于基板100的第一边110上，第二电极220位于基板100的第二边120上，且第一边110和第二边120相互垂直。在该实施例中，检测到在感应单元上的触摸位置之后，即可获得在触摸屏之上的触摸位置。 As shown in FIG. 9a, in this embodiment, thefirst electrode 210 of thesensing unit 200 is located on thefirst side 110 of thesubstrate 100, thesecond electrode 220 is located on thesecond side 120 of thesubstrate 100, and thefirst side 110 and Thesecond sides 120 are perpendicular to each other. In this embodiment, after the touch position on the sensing unit is detected, the touch position on the touch screen can be obtained. the

如图10所示，为本实用新型实施例的感应单元被触摸时的示意图。从图10可知，第一电极为210，第二电极为220，触摸位置接近于第二电极220，假设感应单元的长度为10个单位长度，且将感应单元均匀地分为10份，其中，感应单元第六部分280的长度为5个单位长度，感应单元第七部分290的长度为5个单位长度。经过检测，获知第一电阻和第二电阻之比为9:1，即第一电极210至触摸位置的长度（由第一电阻体现）为全部感应单元长度的90%。换句话说，触摸点位于距离第一电极210处9个单位长度的位置，获知，触摸点位于距离第二电极220处1个单位长度的位置。 As shown in FIG. 10 , it is a schematic diagram when the sensing unit of the embodiment of the present invention is touched. It can be seen from FIG. 10 that the first electrode is 210, the second electrode is 220, and the touch position is close to thesecond electrode 220. Assume that the length of the sensing unit is 10 unit lengths, and the sensing unit is evenly divided into 10 parts. Among them, The length of thesixth part 280 of the sensing unit is 5 unit lengths, and the length of theseventh part 290 of the sensing unit is 5 unit lengths. After testing, it is known that the ratio of the first resistor to the second resistor is 9:1, that is, the length from thefirst electrode 210 to the touch position (represented by the first resistor) is 90% of the length of the entire sensing unit. In other words, the touch point is located at a position of 9 unit lengths away from thefirst electrode 210 , and it is known that the touch point is located at a position of 1 unit length away from thesecond electrode 220 . the

从图10的以上例子可以看出，本实用新型的计算方式非常简单，因此能够极大地提高触摸屏检测的反应速度。 It can be seen from the above example in FIG. 10 that the calculation method of the present invention is very simple, so the reaction speed of touch screen detection can be greatly improved. the

在本实用新型的一个实施例中，多个感应单元200位于同一层，因此只需要一层ITO即可，从而在保证精度的同时，极大地降低制造成本。 In one embodiment of the present invention, multiple sensingunits 200 are located on the same layer, so only one layer of ITO is needed, thereby greatly reducing manufacturing cost while ensuring accuracy. the

本实用新型实施例的触摸屏检测装置中的感应单元采用双端检测，即感应单元的两端均具有电极，且每个电极均与触摸屏控制芯片的对应管脚相连，在进行触摸检测时通过感应单元自身即可实现对触摸点的定位。 The sensing unit in the touch screen detection device of the embodiment of the utility model adopts double-terminal detection, that is, both ends of the sensing unit have electrodes, and each electrode is connected to the corresponding pin of the touch screen control chip, and the touch detection is performed by sensing The unit itself can realize the positioning of the touch point. the

更为重要的是，本实用新型通过计算第一电阻和第二电阻之间比例实现触摸位置的确定，因此相对于目前的菱形或三角形设计来说，由于在确定触摸位置时，无需计 算自电容的大小，且自电容的大小不会影响触摸位置的精度，对自电容检测精度的依赖降低，从而提高了测量精度，改善了线性度。 More importantly, the utility model realizes the determination of the touch position by calculating the ratio between the first resistance and the second resistance. Therefore, compared with the current rhombus or triangle design, there is no need to calculate the touch position when determining the touch position. The size of the capacitance, and the size of the self-capacitance will not affect the accuracy of the touch position, and the dependence on the detection accuracy of the self-capacitance is reduced, thereby improving the measurement accuracy and improving the linearity. the

综上所述，本实用新型实施例通过对感应单元两端的电极施加电平信号，如果该感应单元被触碰，则会该感应单元会形成自电容，因此本实用新型通过施加的电平信号可对该自电容进行充电，并根据第一电阻和第二电阻之间的比例关系确定在第一方向上的触摸位置。例如在本实用新型的一个实施例中，第一电阻和第二电阻之间的比例关系根据在对所述自电容充电/放电时，从所述第一电极和/或第二电极进行检测获得的第一检测值和第二检测值之间的比例关系计算得到。因此从第一电极和/或第二电极检测该自电容充电/放电时产生的第一检测值和第二检测值。这样，通过第一检测值和第二检测值就能够反应触摸点位于该感应单元的位置，从而进一步确定触摸点在触摸屏的位置。 To sum up, the embodiment of the utility model applies a level signal to the electrodes at both ends of the sensing unit. If the sensing unit is touched, the sensing unit will form a self-capacitance. The self-capacitance can be charged, and the touch position in the first direction can be determined according to the proportional relationship between the first resistance and the second resistance. For example, in one embodiment of the present utility model, the proportional relationship between the first resistance and the second resistance is obtained from the detection of the first electrode and/or the second electrode when charging/discharging the self-capacitance The proportional relationship between the first detection value and the second detection value is calculated. Therefore, the first detection value and the second detection value generated when the self-capacitance is charged/discharged are detected from the first electrode and/or the second electrode. In this way, the position of the touch point on the sensing unit can be reflected by the first detection value and the second detection value, so as to further determine the position of the touch point on the touch screen. the

本实用新型实施例提出了一种新颖的自电容检测方式，在感应单元被触摸时，触摸点就可将该感应单元分为两个电阻，从而在进行自电容检测的同时考虑这两个电阻就可以确定触摸点在该感应单元上的位置。本实用新型实施例的结构简单，并且对于一个感应单元来说，可从其的第一电极和/或第二电极进行充电或放电，并在充电或放电时进行检测，不仅能够降低RC常数，节省时间提高效率，并且还能够保证坐标不会偏移。此外，本实用新型实施例还可以有效提高电路的性噪比，降低电路噪声，提高感应线性度。并且，在检测过程中由于对被触摸的感应单元进行充电，因此其中会产生小电流，能够很好地消除Vcom电平信号对触摸屏中感应单元产生的自电容的影响，因此可以相应地消除屏幕屏蔽层及相关工序，从而可以在增强了抗干扰能力的同时进一步降低成本。 The embodiment of the utility model proposes a novel self-capacitance detection method. When the sensing unit is touched, the touch point can divide the sensing unit into two resistances, so that the two resistances can be considered while performing self-capacitance detection. Then the position of the touch point on the sensing unit can be determined. The structure of the embodiment of the utility model is simple, and for an induction unit, it can be charged or discharged from its first electrode and/or second electrode, and can be detected during charging or discharging, which can not only reduce the RC constant, It saves time and improves efficiency, and it can also ensure that the coordinates will not shift. In addition, the embodiment of the utility model can also effectively improve the SNR of the circuit, reduce the noise of the circuit, and improve the linearity of induction. Moreover, in the detection process, since the touched sensing unit is charged, a small current will be generated in it, which can well eliminate the influence of the Vcom level signal on the self-capacitance generated by the sensing unit in the touch screen, so the screen can be correspondingly eliminated. The shielding layer and related processes can further reduce the cost while enhancing the anti-interference ability. the
