本实用新型涉及电子设备技术领域，特别涉及一种触控装置及具有其的移动终端。The utility model relates to the technical field of electronic equipment, in particular to a touch device and a mobile terminal with the same.
背景技术Background technique
电容式电容屏已经广泛的应用于各种领域，例如：手机触摸屏、笔记本touchpad、PDAs、键盘等。该电容式电容屏通过人体手指与电容屏的接触使互电容发生改变，接着通过检测判断出手指在屏幕上的位置。以手机电容屏幕为例，一般来说存在以下缺点。Capacitive capacitive screens have been widely used in various fields, such as: mobile phone touch screens, notebook touchpads, PDAs, keyboards, etc. The capacitive capacitive screen changes the mutual capacitance through the contact of the finger of the human body with the capacitive screen, and then judges the position of the finger on the screen through detection. Taking the capacitive screen of a mobile phone as an example, generally speaking, there are the following disadvantages.
第一，当手指未接触或者接近屏幕的时候，屏幕都在不断的进行扫描工作，也就是说在不停的进行电容变化量的检测与判定，使芯片处在一个不断扫描的工作状态，会消耗相当一部分的能源。First, when the finger is not touching or close to the screen, the screen is constantly scanning, that is to say, it is constantly detecting and judging the capacitance change, so that the chip is in a continuous scanning working state, which will Consume a considerable amount of energy.
第二，手指不会时刻停留在屏幕上，更多的情况是在屏幕上方移动或做预按的动作，当决定选择一个操作时才会点击屏幕，当手指接近屏幕但未接触时互电容已经在发生变化，就可能使控制器，如手机触摸屏的控制芯片判断为有效的触碰，进而执行错误的操作。Second, the finger will not stay on the screen all the time. More often, it will move above the screen or do a pre-press action. When it is decided to choose an operation, it will click the screen. When the finger is close to the screen but not in contact, the mutual capacitance has already passed. If there is a change, the controller, such as the control chip of the touch screen of the mobile phone, may be judged to be a valid touch, and then perform an erroneous operation.
第三，手指相对屏幕上的各种图标按键来说普遍偏大，当手指触摸屏幕时经常会出现覆盖两个或者以上的图标，通常会造成操作上的失误。Third, fingers are generally too large for various icon keys on the screen. When the finger touches the screen, two or more icons often appear, which usually causes operational errors.
现有技术的缺点为，以上三种情况很可能会造成时间的浪费和不必要的能耗，并且会严重影响使用者的心情。The disadvantage of the prior art is that the above three situations are likely to cause waste of time and unnecessary energy consumption, and will seriously affect the user's mood.

以下结合附图1-2首先描述本实用新型实施例的触控装置的控制方法。The control method of the touch device according to the embodiment of the present invention will be firstly described below with reference to FIGS. 1-2 .
如图1所示，为本实用新型实施例的触控装置的控制方法的流程图。根据本实用新型实施例的触控装置的控制方法，包括以下步骤：As shown in FIG. 1 , it is a flowchart of a control method of a touch device according to an embodiment of the present invention. A control method for a touch device according to an embodiment of the present invention includes the following steps:
步骤S101，检测所述触控装置的触摸屏上的电容变化，并获得电容变化处的电容变化量。Step S101 , detecting the capacitance change on the touch screen of the touch device, and obtaining the capacitance change amount at the place where the capacitance changes.
在本实用新型的一些实施例中，例如通过电容检测单元检测触控装置的触摸屏上的电容变化并获得电容变化处的电容变化量。由于电容检测单元可以持续地检测触摸屏的电容变化情况，因此可以随时地获得触摸屏电容变化处的电容变化量。In some embodiments of the present invention, for example, the capacitance change on the touch screen of the touch device is detected by the capacitance detection unit, and the capacitance change at the capacitance change is obtained. Since the capacitance detection unit can continuously detect the capacitance change of the touch screen, the capacitance change at the touch screen capacitance change can be obtained at any time.
步骤S102，根据所述电容变化量判断触碰物体是否临近所述触摸屏，并分别触发物体临近信号和物体未临近信号。Step S102 , judging whether the touching object is close to the touch screen according to the amount of capacitance change, and triggering an object approaching signal and an object not approaching signal respectively.
换句话说，由于触碰物体与触摸屏表面的距离的改变，该触碰物体与触摸屏将要接触的触摸屏上的点的位置电容将改变并产生一个电容变化量，这样，可以将该点的电容变化量与一个预定电容阈值进行比较，从而可以大致确定该触碰物体与触摸屏表面之间距离的一个范围区间，进而，可以确定该触碰物体是否临近触摸屏，并根据确定结果分别触发物体的邻近信号和物体的未临近信号。In other words, due to the change of the distance between the touching object and the surface of the touch screen, the position capacitance of the point on the touch screen where the touching object and the touch screen will be in contact will change and produce a capacitance variation. In this way, the capacitance of the point can be changed The amount is compared with a predetermined capacitance threshold, so that a range interval of the distance between the touching object and the surface of the touch screen can be roughly determined, and then it can be determined whether the touching object is close to the touch screen, and the proximity signal of the object is respectively triggered according to the determination result and non-adjacent signals of objects.
步骤S103，如果所述触控装置的控制器接收到所述物体未临近信号且在预定时间周期之内持续接收到所述物体未临近信号，则控制所述触控装置的控制器进入休眠状态，并返回执行步骤S101。Step S103, if the controller of the touch device receives the signal that the object is not approaching and continues to receive the signal that the object is not approaching within a predetermined period of time, then controlling the controller of the touch device to enter a sleep state , and return to step S101.
具体地，如果所述触控装置的控制器在上一次接收到的信号为临近信号，且在这一次接收到的信号为所述物体未临近信号时，开始计时，并在预定时间周期之内持续收到所述物体未临近信号，则控制所述触控装置的控制器进入休眠状态。Specifically, if the last signal received by the controller of the touch control device is an approach signal, and the signal received this time is a signal that the object is not approaching, start timing, and within a predetermined time period After continuously receiving the signal that the object is not approaching, the controller for controlling the touch device enters a dormant state.
在本实用新型的一个实施例中，如该预定时间周期可以为5秒。这样，可以防止因物体在短暂的某一时刻未临近触摸屏，导致控制器休眠，从而防止该触控装置的控制器在休眠与正常工作状态之间转换过于频繁而降低触控装置使用寿命，并减少了如果有触摸时，控制器从休眠状态再进入正常工作状态导致的触摸操作延迟。In an embodiment of the present invention, for example, the predetermined time period may be 5 seconds. In this way, it is possible to prevent the controller from sleeping due to the fact that the object is not close to the touch screen at a short moment, thereby preventing the controller of the touch device from switching between sleep and normal working states too frequently and reducing the service life of the touch device, and Reduced the touch operation delay caused by the controller entering the normal working state from the dormant state if there is a touch.
步骤S104，如果所述触控装置的控制器接收到所述物体临近信号，则控制所述触控装置的控制器进入工作状态。Step S104, if the controller of the touch device receives the object approach signal, control the controller of the touch device to enter the working state.
在本实用新型的一些示例中，例如在控制器进入工作状态后，可以计算触碰物体在所述触摸屏上的位置，并根据该位置的位置坐标执行与物体临近信号相关联的指令。如放大触摸屏上的该点坐标处的局部区域，由于触碰物体相对触摸屏上的各种图标按键来说普遍偏大，很可能导致触碰物体触碰触摸屏时出现覆盖两个或者更多图标，进而浪费时间。这样，通过放大触摸屏上的该点坐标处的局部区域，可有效防止误操作，进而增强用户体验效果。In some examples of the present invention, for example, after the controller enters the working state, the position of the touch object on the touch screen can be calculated, and the instruction associated with the object proximity signal can be executed according to the position coordinates of the position. If you zoom in on the local area at the coordinates of the point on the touch screen, since the touch object is generally larger than the various icon buttons on the touch screen, it is likely to cause two or more icons to appear when the touch object touches the touch screen. Thus wasting time. In this way, by enlarging the local area at the coordinates of the point on the touch screen, misoperations can be effectively prevented, thereby enhancing user experience.
根据本实用新型实施例的触控装置的触控方法，通过对该触控装置的触摸屏上电容变化处的电容变化量大小的判断，可以有效地判断出触碰物体是否临近触摸屏，并在触碰物体邻近触摸屏时，使该触控装置的控制器进入工作状态，否则，可以使该触控装置的控制器进入休眠状态。这样，在控制器进入休眠状态后，该控制器的能耗降低，进而提高了该触控装置的使用寿命。According to the touch control method of the touch device according to the embodiment of the present invention, by judging the magnitude of the capacitance change at the capacitance change point on the touch screen of the touch device, it can be effectively judged whether the touch object is close to the touch screen, and when the touch When the touch object is close to the touch screen, the controller of the touch device enters the working state; otherwise, the controller of the touch device enters the sleep state. In this way, after the controller enters the dormant state, the energy consumption of the controller is reduced, thereby increasing the service life of the touch device.
在本实用新型的示例中，触控装置的触摸屏分为自电容触摸屏或互电容屏。进一步地，步骤S102包括如下步骤：In an example of the present invention, the touch screen of the touch device is classified into a self-capacitance touch screen or a mutual-capacitance touch screen. Further, step S102 includes the following steps:
首先将所述电容变化量与第一预定电容阈值进行比较。在具体应用中，第一预定电容阈值可根据相应的自电容触摸屏或互电容屏预先测定。Firstly, the capacitance variation is compared with a first predetermined capacitance threshold. In specific applications, the first predetermined capacitance threshold can be pre-determined according to the corresponding self-capacitance touch screen or mutual capacitance touch screen.
接着当判断所述电容变化量大于所述第一预定电容阈值时，触发所述物体临近信号，否则触发所述物体未临近信号。Then, when it is judged that the capacitance variation is greater than the first predetermined capacitance threshold, the object proximity signal is triggered; otherwise, the object non-proximity signal is triggered.
具体而言，如果电容检测单元检测到触摸屏上某一位置的电容发送变化，且变化量大于第一预定电容阈值，则认为有物体临近触摸屏，则触发所述物体临近信号。如果判断没有物体临近触摸屏，则触发物体未临近信号。例如，当物体临近触摸屏时其采用的第一预定电容阈值为ΔC1，而电容变化量为ΔC，当判断ΔC1≤ΔC，即表示有物体临近触摸屏，此时触发物理临近信号。根据上述实施例，在步骤S104中，当控制器接收到物理临近信号后进入工作状态之后，还用于根据电容变化量判断所述触碰物体是否有效触碰所述触摸屏并触发与所述有效触碰相关联的信号。Specifically, if the capacitance detection unit detects a change in capacitance transmission at a certain position on the touch screen, and the change amount is greater than the first predetermined capacitance threshold, it is considered that an object is close to the touch screen, and the object proximity signal is triggered. If it is judged that there is no object approaching the touch screen, an object not approaching signal is triggered. For example, when an object is close to the touch screen, the first predetermined capacitance threshold value is ΔC1, and the capacitance change is ΔC. When it is judged that ΔC1≤ΔC, it means that an object is close to the touch screen, and the physical proximity signal is triggered at this time. According to the above-mentioned embodiment, in step S104, when the controller enters the working state after receiving the physical proximity signal, it is also used to judge whether the touch object effectively touches the touch screen according to the amount of capacitance change and trigger the touch screen with the effective Touch the associated signal.
如图2所示，判断所述触碰物体是否有效触碰所述触摸屏并触发与所述有效触碰相关联的信号，具体为以下步骤：As shown in FIG. 2 , judging whether the touch object effectively touches the touch screen and triggers a signal associated with the effective touch involves the following steps:
步骤S1041：将所述电容变化量与第二预定电容阈值进行比较。Step S1041: Comparing the capacitance variation with a second predetermined capacitance threshold.
步骤S1042：如果所述电容变化量大于所述第二预定电容阈值，则触发有效触摸信号并提供给所述触控装置的控制器，否则返回执行步骤S101。例如，当物体有效触摸到触摸屏时采用的第二阈值为ΔC2。明显地，ΔC2应大于ΔC1。而此时的电容变化量记为ΔC，当判断ΔC2≤ΔC时，即表示物体有效触摸到触摸屏，触发有效触摸信号并提供给控制器。例如，控制器根据有效触摸信号获得有效触摸点的坐标，从而判断有效触摸的图标，并执行图标相关联的指令。如打开一个应用程序、输入文字等。Step S1042: If the capacitance variation is greater than the second predetermined capacitance threshold, trigger a valid touch signal and provide it to the controller of the touch device, otherwise return to step S101. For example, the second threshold used when the object effectively touches the touch screen is ΔC2. Obviously, ΔC2 should be greater than ΔC1. At this time, the amount of capacitance change is recorded as ΔC. When it is judged that ΔC2≤ΔC, it means that the object effectively touches the touch screen, triggers an effective touch signal and provides it to the controller. For example, the controller obtains the coordinates of the valid touch point according to the valid touch signal, so as to determine the validly touched icon, and execute the instruction associated with the icon. Such as opening an application, entering text, etc.
以下结合附图3描述根据本实用新型实施例的触控装置。The touch device according to the embodiment of the present utility model will be described below with reference to FIG. 3 .
如图3所示，为本实用新型实施例的触控装置的结构图。根据本实用新型实施例的触控装置300包括：触摸屏310、电容检测单元320、临近判定单元330和控制器340。As shown in FIG. 3 , it is a structural diagram of a touch device according to an embodiment of the present invention. The touch device 300 according to the embodiment of the present invention includes: a touch screen 310 , a capacitance detection unit 320 , a proximity determination unit 330 and a controller 340 .
电容检测单元320用于检测所述触控装置300的触摸屏310上的电容变化，并获得电容变化处的电容变化量。由于电容检测单元可以持续地检测触摸屏的电容变化情况，因此可以随时地获得触摸屏电容变化处的电容变化量。The capacitance detection unit 320 is used for detecting the capacitance change on the touch screen 310 of the touch control device 300 , and obtaining the capacitance change amount at the place where the capacitance changes. Since the capacitance detection unit can continuously detect the capacitance change of the touch screen, the capacitance change at the touch screen capacitance change can be obtained at any time.
临近判定单元330用于根据所述电容变化量判断触碰物体是否临近所述触摸屏310，并分别触发物体临近信号和物体未临近信号。The proximity determination unit 330 is configured to determine whether the touch object is close to the touch screen 310 according to the amount of capacitance change, and trigger an object proximity signal and an object non-proximity signal respectively.
换句话说，由于触碰物体与触摸屏310表面的距离的改变，该触碰物体与触摸屏310将要接触的触摸屏310上的点的位置电容将改变并产生一个电容变化量，这样，临近判定单元330可以将该点的电容变化量与一个预定电容阈值进行比较，从而可以大致确定该触碰物体与触摸屏310表面之间距离的一个范围区间，进而，可以确定该触碰物体是否临近触摸屏310，并根据确定结果分别触发物体的邻近信号和物体的未临近信号。In other words, due to the change of the distance between the touching object and the surface of the touch screen 310, the capacitance of the point on the touch screen 310 where the touching object and the touch screen 310 will be in contact will change and generate a capacitance variation. In this way, the proximity determination unit 330 The capacitance variation at this point can be compared with a predetermined capacitance threshold, so that a range interval of the distance between the touching object and the surface of the touch screen 310 can be roughly determined, and then it can be determined whether the touching object is close to the touch screen 310, and The proximity signal of the object and the non-proximity signal of the object are respectively triggered according to the determination result.
控制器340接收到所述物体未临近信号且在预定时间周期之内持续接收到所述物体未临近信号，则控制所述触控装置300的控制器340进入休眠状态，如果所述控制器340接收到所述物体临近信号，则触发所述控制器340进入工作状态。The controller 340 receives the object non-approaching signal and continues to receive the object non-approaching signal within a predetermined time period, then controls the controller 340 of the touch device 300 to enter a sleep state, if the controller 340 Upon receiving the object approach signal, the controller 340 is triggered to enter the working state.
具体地，如果所述触控装置300的控制器340在上一次接收到的信号为临近信号，且在这一次接收到的信号为所述物体未临近信号时，开始计时，并在预定时间周期之内持续收到所述物体未临近信号，则控制所述触控装置300的控制器340进入休眠状态。Specifically, if the last signal received by the controller 340 of the touch control device 300 is an approach signal, and the signal received this time is a signal that the object is not approaching, start counting, and within a predetermined time period The controller 340 controlling the touch device 300 enters a dormant state if the object is not approaching signal is continuously received within the period.
在本实用新型的一个实施例中，如该预定时间周期可以为5秒。这样，可以防止因物体在短暂的某一时刻未临近触摸屏，导致控制器休眠，从而防止该触控装置的控制器在休眠与正常工作状态之间转换过于频繁而降低触控装置使用寿命，并减少了如果有触摸时，控制器从休眠状态再进入正常工作状态导致的触摸操作延迟。In an embodiment of the present invention, for example, the predetermined time period may be 5 seconds. In this way, it is possible to prevent the controller from sleeping due to the fact that the object is not close to the touch screen at a short moment, thereby preventing the controller of the touch device from switching between sleep and normal working states too frequently and reducing the service life of the touch device, and Reduced the touch operation delay caused by the controller entering the normal working state from the dormant state if there is a touch.
结合图3，在本实用新型的一些示例中，控制器340还包括位置计算模块341，当控制器340进入工作状态后，计算模块341可以计算触碰物体在所述触摸屏上的位置，并根据该位置的位置坐标执行与物体临近信号相关联的指令。如放大触摸屏310上的该点坐标处的局部区域，由于触碰物体相对触摸屏310上的各种图标按键来说普遍偏大，很可能导致触碰物体触碰触摸屏310时出现覆盖两个或者更多图标，进而浪费时间。这样，通过放大触摸屏310上的该点坐标处的局部区域，可有效防止误操作，进而增强用户体验效果。3, in some examples of the present invention, the controller 340 also includes a
根据本实用新型实施例的触控装置300，首先该触控装置300的电容检测单元320检测到的触摸屏310上电容变化处的电容变化量，接着临近判定单元330通过对该电容变化量的大小的判定，可以有效地判断出触碰物体是否临近触摸屏310，并在判断出触碰物体邻近触摸屏310时，使该触控装置300的控制器340进入工作状态，否则，可以使该触控装置300的控制器340进入休眠状态。这样，在控制器340进入休眠状态后，实现了该触控装置300降低能耗的目的，进而提高了该触控装置300的使用寿命。另外，该触控装置300设计简单，成本低。According to the touch control device 300 of the embodiment of the present invention, firstly, the capacitance change amount of the capacitance change position on the touch screen 310 detected by the capacitance detection unit 320 of the touch control device 300, and then the proximity determination unit 330 passes the capacitance change amount The judgment can effectively determine whether the touch object is close to the touch screen 310, and when it is judged that the touch object is close to the touch screen 310, the controller 340 of the touch device 300 can enter the working state; The controller 340 of 300 enters a sleep state. In this way, after the controller 340 enters the dormant state, the purpose of reducing the energy consumption of the touch device 300 is achieved, thereby increasing the service life of the touch device 300 . In addition, the touch device 300 is simple in design and low in cost.
结合图3，在本实用新型的示例中，触控装置300的触摸屏310分为自电容触摸屏或互电容屏。临近判定单元330首先将自电容触摸屏或互电容屏的电容变化量与第一预定电容阈值进行比较。在具体应用中，第一预定电容阈值可根据相应的自电容触摸屏或互电容屏预先测定，接着临近判定单元330当判断所述电容变化量大于所述第一预定电容阈值时，触发所述物体临近信号，否则触发所述物体未临近信号。Referring to FIG. 3 , in an example of the present invention, the touch screen 310 of the touch device 300 is classified into a self-capacitance touch screen or a mutual-capacitance touch screen. The proximity determination unit 330 first compares the capacitance variation of the self-capacitance touch screen or the mutual capacitance screen with a first predetermined capacitance threshold. In a specific application, the first predetermined capacitance threshold can be pre-determined according to the corresponding self-capacitance touch screen or mutual capacitance screen, and then the proximity determination unit 330 triggers the object when it judges that the capacitance change is greater than the first predetermined capacitance threshold. Proximity signal, otherwise, the object is not close to the signal is triggered.
具体而言，如果电容检测单元320检测到触摸屏310上某一位置的电容发送变化，且变化量大于第一预定电容阈值，临近判定单元330认为有物体临近触摸屏310，则触发所述物体临近信号。如果判断没有物体临近触摸屏310，则触发物体未临近信号。例如，当物体临近触摸屏310时其采用的第一预定电容阈值为ΔC1，而电容变化量为ΔC，当判断ΔC1≤ΔC，即表示有物体临近触摸屏310，此时触发物理临近信号。Specifically, if the capacitance detection unit 320 detects a change in the capacitance transmission at a certain position on the touch screen 310, and the change amount is greater than the first predetermined capacitance threshold, the proximity determination unit 330 considers that there is an object approaching the touch screen 310, and triggers the object proximity signal. . If it is judged that there is no object approaching the touch screen 310, an object non-approaching signal is triggered. For example, when an object is close to the touch screen 310, the first predetermined capacitance threshold value is ΔC1, and the capacitance change is ΔC. When it is judged that ΔC1≤ΔC, it means that an object is close to the touch screen 310, and the physical proximity signal is triggered at this time.
在本实用新型的另一些实施例中，当控制器340接收到物理临近信号进入工作状态之后，用于根据电容变化量判断所述触碰物体是否有效触碰所述触摸屏310并触发与所述有效触碰相关联的信号。In some other embodiments of the present invention, after the controller 340 receives the physical proximity signal and enters the working state, it is used to judge whether the touch object effectively touches the touch screen 310 according to the amount of capacitance change and trigger the contact with the touch screen 310. Effectively touches the associated signal.
具体地，控制器340将所述电容变化量与第二预定电容阈值进行比较，如果判断所述电容变化量大于所述第二预定阈值，则触发有效触摸信号并提供给所述触控装置300的控制器340。例如，当物体有效触摸到触摸屏时采用的第二阈值为ΔC2。明显地，ΔC2应大于ΔC1。而此时的电容变化量记为ΔC，当判断ΔC2≤ΔC时，即表示物体有效触摸到触摸屏310，触发有效触摸信号并提供给控制器。例如，控制器根据有效触摸信号获得有效触摸点的坐标，从而判断有效触摸的图标，并执行图标相关联的指令。如打开一个应用程序、输入文字等。Specifically, the controller 340 compares the capacitance variation with a second predetermined capacitance threshold, and if it is determined that the capacitance variation is greater than the second predetermined threshold, an effective touch signal is triggered and provided to the touch device 300 The controller 340. For example, the second threshold used when the object effectively touches the touch screen is ΔC2. Obviously, ΔC2 should be greater than ΔC1. The capacitance change at this time is recorded as ΔC. When it is judged that ΔC2 ≤ ΔC, it means that the object effectively touches the touch screen 310 , triggering a valid touch signal and providing it to the controller. For example, the controller obtains the coordinates of the valid touch point according to the valid touch signal, so as to determine the validly touched icon, and execute the instruction associated with the icon. Such as opening an application, entering text, etc.
根据本实用新型的控制方法，可通过有效的判断，使控制器在休眠与工作两种状态间转换，降低控制器在休眠时的能耗，进而提高该触控装置的使用寿命。根据本实用新型的控制装置，可使控制器适当地在休眠与工作两种状态间转换，从而达到降低能耗的目的。According to the control method of the utility model, the controller can be switched between the sleep state and the work state through effective judgment, reducing the energy consumption of the controller in sleep state, and further improving the service life of the touch device. According to the control device of the utility model, the controller can be properly switched between the sleep state and the working state, so as to achieve the purpose of reducing energy consumption.
