本发明涉及触控技术领域，尤其涉及一种触控电极结构、触控面板、显示装置和定位触控点的方法。The present invention relates to the field of touch technology, in particular to a touch electrode structure, a touch panel, a display device and a method for locating a touch point.
背景技术Background technique
互电容触控屏又称为互电容触摸屏，是一种可接收触头等输入讯号的感应式液晶显示装置，当用户点击互电容触控屏上的图形按钮时，互电容触控屏上的触控反馈系统可根据预先编程的程式驱动各种连结装置，并借助液晶显示画面制造出生动的影音效果。Mutual capacitance touch screen, also known as mutual capacitance touch screen, is an inductive liquid crystal display device that can receive input signals such as contacts. When the user clicks the graphic button on the mutual capacitance touch screen, the The touch feedback system can drive various connected devices according to pre-programmed programs, and create vivid audio-visual effects with the help of LCD screens.
互电容触控屏采用触控电极结构定位触控点。如图1所示，触控电极结构包括为触控驱动电极和触控感应电极，其中，Xj和Xj+1为触控驱动电极，Yi和Yi+1为触控感应电极。当手指接触时，与触控点相对应位置的触控驱动电极和触控感应电极之间的互电容改变，从而可以定位触控点。Mutual capacitive touch screens use a touch electrode structure to locate touch points. As shown in FIG. 1 , the touch electrode structure includes touch driving electrodes and touch sensing electrodes, wherein Xj and Xj+1 are touch driving electrodes, and Yi and Yi+1 are touch sensing electrodes. When a finger touches, the mutual capacitance between the touch driving electrode and the touch sensing electrode corresponding to the touch point changes, so that the touch point can be located.
目前，通过频率为60Hz的帧频(Tearing Effect，TE)信号控制互电容触控屏的显示时间和定位触控点的触控时间，分时驱动触控驱动电极定位触控点。在1帧频内显示时间与触控时间的分布情况如图2所示。以一定尺寸的互电容触控屏搭载M个触控驱动电极与N个触控感应电极为例进行说明，在触控时间内需要分别驱动M个触控驱动电极，驱动每个触控驱动电极的时间为T，则共驱动所有触控驱动电极的时间为M*T。随着互电容触控屏的尺寸增大，触控驱动电极数量M增多，而且触控显示屏本身电阻电容延迟(RC Dealy)增大，使得T相应变大，需要触控时间总时间t＝T*M变大，因此会占用显示的时间，影响互电容触控屏的显示效果。At present, the display time of the mutual capacitance touch screen and the touch time of positioning the touch point are controlled by a frame frequency (Tearing Effect, TE) signal with a frequency of 60 Hz, and the touch driving electrodes are time-divisionally driven to position the touch point. The distribution of display time and touch time within 1 frame rate is shown in Figure 2. Taking a mutual capacitance touch screen of a certain size equipped with M touch driving electrodes and N touch sensing electrodes as an example, it is necessary to drive M touch driving electrodes separately during the touch time, and drive each touch driving electrode The time is T, and the time for driving all the touch driving electrodes is M*T. As the size of the mutual-capacitance touch screen increases, the number of touch-driving electrodes M increases, and the resistance-capacitance delay (RC Dealy) of the touch screen itself increases, making T correspondingly larger, and the total time required for touch control is t= T*M becomes larger, so it will take up the display time and affect the display effect of the mutual capacitance touch screen.

具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
由背景技术可知，以一定尺寸的互电容触控屏搭载M个第一触控电极与N个触控感应触控电极为例进行说明，在触控时间内需要分别驱动M个第一触控电极，驱动每个第一触控电极的时间为T，则共驱动所有第一触控电极的时间为M*T。随着互电容触控屏的尺寸增大，第一触控电极数量M增多，而且触控显示屏本身电阻电容延迟(RC Dealy)增大，使得T相应变大，需要触控时间总时间t＝T*M变大，因此会占用显示的时间，影响互电容触控屏的显示效果。It can be known from the background technology that a mutual capacitance touch screen of a certain size is equipped with M first touch electrodes and N touch-sensitive touch electrodes as an example, and M first touch electrodes need to be respectively driven within the touch time. electrodes, the time to drive each first touch electrode is T, and the time to drive all the first touch electrodes is M*T. As the size of the mutual-capacitance touch screen increases, the number M of the first touch electrodes increases, and the resistance-capacitance delay (RC Dealy) of the touch screen itself increases, making T correspondingly larger, requiring a total touch time t = T * M becomes larger, so it will take up the display time and affect the display effect of the mutual capacitance touch screen.
有鉴于此，本发明实施例提供了一种触控电极结构、触控面板、显示装置和定位触控点的方法，以解决由于在1帧频内触控时间长，造成显示时间缩短，从而影响互电容触控屏的显示效果的技术问题。具体通过以下实施例进行说明。本发明实施例提供了一种触控电极结构，如图3(a)所示，多个第一触控电极31、多个第二触控电极32和多个第三触控电极33；其中，各个第一触控电极31与各个第二触控电极32平行且间隔设置，第三触控电极33与第一触控电极31交叉设置，且第三触控电极33与第二触控电极32交叉设置；第一触控电极31、第二触控电极32和第三触控电极33之间电绝缘。In view of this, the embodiments of the present invention provide a touch electrode structure, a touch panel, a display device, and a method for locating a touch point, so as to solve the problem that the display time is shortened due to the long touch time within 1 frame rate, thereby A technical problem that affects the display effect of the mutual capacitance touch screen. Specifically, it is illustrated by the following examples. The embodiment of the present invention provides a touch electrode structure, as shown in FIG. 3(a), a plurality of first touch electrodes 31, a plurality of second touch electrodes 32 and a plurality of third touch electrodes 33; wherein , each first touch electrode 31 is arranged parallel to each second touch electrode 32 at intervals, the third touch electrode 33 is arranged intersecting with the first touch electrode 31 , and the third touch electrode 33 and the second touch electrode 32 are arranged across; the first touch electrodes 31 , the second touch electrodes 32 and the third touch electrodes 33 are electrically insulated.
在上述触控电极结构中，如图3(a)所示，X1为第一触控电极31，Z1为第二触控电极32，Y1、Y2和Y3为第三触控电极33，其中，第一触控电极31与第二触控电极32为直线型。In the above touch electrode structure, as shown in FIG. 3(a), X1 is the first touch electrode 31, Z1 is the second touch electrode 32, Y1, Y2 and Y3 are the third touch electrode 33, wherein The first touch electrodes 31 and the second touch electrodes 32 are linear.
需要进行说明的是，每个第一触控电极对应平行设置一个第二触控电极，每两个第一触控电极之间间隔一个第二触控电极。第一触控电极、第二触控电极和第三触控电极之间填充有绝缘材料，实现第一触控电极和第二触控电极之间电绝缘，第一触控电极和第三触控电极之间电绝缘，第二触控电极和第三触控电极之间。It should be noted that each first touch electrode corresponds to a second touch electrode arranged in parallel, and a second touch electrode is spaced between every two first touch electrodes. An insulating material is filled between the first touch electrode, the second touch electrode and the third touch electrode to realize electrical insulation between the first touch electrode and the second touch electrode, and the first touch electrode and the third touch electrode Electrical insulation between the control electrodes, between the second touch electrodes and the third touch electrodes.
本发明提供的实施例与现有技术相比，增加了与第一触控电极数量相同的第二触控电极，可以仅通过驱动第一触控电极或未被第一触控电极包围的第二触控电极，同时检测第一触控电极与第二触控电极之间的第一参数，第一触控电极或未被第一触控电极包围的第二触控电极与第三触控电极的之间的第二参数，初步定位触控点位置。并可以进一步通过依次驱动被触发的第一触控电极或被触发且未被第一触控电极包围的第二触控电极，检测其与第三触控电极之间的第三参数，精确定位触控点位置。因此在较大尺寸屏幕中使用较少数量的第一触控电极，降低驱动第一触控电极的时间，从而延长显示时间，提高互电容触控屏的显示效果。Compared with the prior art, the embodiment provided by the present invention adds the same number of second touch electrodes as the first touch electrodes, and can only drive the first touch electrodes or the first touch electrodes not surrounded by the first touch electrodes. Two touch electrodes, simultaneously detect the first parameter between the first touch electrode and the second touch electrode, the first touch electrode or the second touch electrode not surrounded by the first touch electrode and the third touch electrode The second parameter between the electrodes is to initially locate the touch point. Furthermore, by sequentially driving the first touch electrode that is triggered or the second touch electrode that is triggered and not surrounded by the first touch electrode, the third parameter between it and the third touch electrode can be detected to precisely locate Touch point location. Therefore, a smaller number of first touch electrodes is used in a larger-sized screen to reduce the time for driving the first touch electrodes, thereby prolonging the display time and improving the display effect of the mutual-capacitance touch screen.
在实际应用中，第一触控电极、第二触控电极和第三触控电极可以设置在同一层级上，也可以位于不同层级上。如图3(a)所示，第一触控电极31和第二触控电极32设置于第一层级上，第三触控电极33设置于第二层级上。每一第三触控电极33包括多段，各段之间被第一触控电极31和第二触控电极32隔开，各段之间通过设置于第一层级上的过孔34进行跨桥连接。第一触控电极31、第二触控电极32、第三触控电极33处于同一层。另如图3(b)所示，第一触控电极31与第二触控电极32位于第一层级，第三触控电极33位于第二层级，第二层级与第一层级相对设置。第一触控电极31、第二触控电极32为直线型。In practical applications, the first touch electrodes, the second touch electrodes and the third touch electrodes can be arranged on the same layer or on different layers. As shown in FIG. 3( a ), the first touch electrode 31 and the second touch electrode 32 are disposed on the first level, and the third touch electrode 33 is disposed on the second level. Each third touch electrode 33 includes multiple segments, each segment is separated by the first touch electrode 31 and the second touch electrode 32, and each segment is bridged by the via hole 34 arranged on the first level. connect. The first touch electrode 31 , the second touch electrode 32 and the third touch electrode 33 are in the same layer. Also as shown in FIG. 3( b ), the first touch electrode 31 and the second touch electrode 32 are located on the first level, the third touch electrode 33 is located on the second level, and the second level is opposite to the first level. The first touch electrodes 31 and the second touch electrodes 32 are linear.
进一步，为增加第一触控电极和第二触控电极之间的互电容，提高定位触摸点的准确性，第一触控电极和第二触控电极还可为非直线型，使得第一触控电极与第二触控电极之间的互电容大于第一触控电极与第二触控电极走线为直线型的情况下的互电容。Furthermore, in order to increase the mutual capacitance between the first touch electrode and the second touch electrode and improve the accuracy of locating the touch point, the first touch electrode and the second touch electrode can also be non-linear, so that the first touch electrode The mutual capacitance between the touch electrodes and the second touch electrodes is greater than the mutual capacitance under the condition that the lines between the first touch electrodes and the second touch electrodes are linear.

Control electrode 43. The first touch electrodes 41 and the second touch electrodes 42 are non-linear. Preferably, the shape of the first touch electrodes 41 and the second touch electrodes 42 is a shape, and the second touch electrodes 42 are in the direction of their extension. Protrusions are provided in the vertical direction, and each first touch electrode 41 extends around the depressions and protrusions of the second touch electrodes 42 to form a figure-shaped structure. The plurality of third touch electrodes 43 are intersected with the plurality of second touch electrodes 42 . Therefore, the mutual capacitance between the first touch electrode 41 and the second touch electrode 42 is larger than that under the condition that the two are linear.
为进一步屏蔽定位触摸点过程中第二触控电极对第三触控电极的干扰，提高判断第一触控电极是否为与触控点位置相对应的第一触控电极的灵敏度。可在图4所示触控电极结构的基础上，将为几字型结构的第一触控电极围绕有凹凸部的第二触控电极。In order to further shield the interference of the second touch electrode to the third touch electrode during the process of locating the touch point, the sensitivity of judging whether the first touch electrode is the first touch electrode corresponding to the position of the touch point is improved. On the basis of the structure of the touch electrodes shown in FIG. 4 , the first touch electrodes with a zigzag structure can be surrounded by the second touch electrodes with concavo-convex portions.

通过本发明实施例提供的一种定位触控点的方法，可以在触控发生后，可以仅通过驱动第一触控电极，同时检测第一触控电极与第二触控电极之间的第一互电容和第一触控电极与第三触控电极的第二互电容，初步定位触控点位置。并可以进一步通过初步位置驱动第一触控电极，检测其与第三触控电极的第三互电容，精确定位触控点位置。因此在较大尺寸屏幕中使用较少数量的第一触控电极，降低驱动第一触控电极的时间，从而延长显示时间，提高互电容触控屏的显示效果。According to a method for locating a touch point provided by an embodiment of the present invention, after a touch occurs, the first touch electrode and the second touch electrode can be detected at the same time only by driving the first touch electrode. A mutual capacitance and a second mutual capacitance between the first touch electrode and the third touch electrode initially position the touch point. Furthermore, the first touch electrode can be driven based on the preliminary position, and the third mutual capacitance between it and the third touch electrode can be detected, so as to accurately locate the position of the touch point. Therefore, a smaller number of first touch electrodes is used in a larger-sized screen to reduce the time for driving the first touch electrodes, thereby prolonging the display time and improving the display effect of the mutual-capacitance touch screen.
在实际操作中，用户可能会连续触控显示装置选择所需的图标或者链接，因此需要判断是否为连续触控。In actual operation, the user may continuously touch the display device to select a desired icon or link, so it is necessary to determine whether the touch is continuous.
因此本发明实施例提供一种定位触控点的方法，其中每个第一触控电极包围一个第二触控电极，其定位触控点的步骤S12001-S1208与上述步骤S1101-S1107一致，在此不再赘述，如图12所示，还包括：Therefore, an embodiment of the present invention provides a method for locating a touch point, wherein each first touch electrode surrounds a second touch electrode, and the steps S12001-S1208 for locating the touch point are the same as the above-mentioned steps S1101-S1107. This will not be repeated here, as shown in Figure 12, it also includes:
步骤S1209，计算当前触控点的坐标与前一次记录的触控点的坐标之间的位移；Step S1209, calculating the displacement between the coordinates of the current touch point and the coordinates of the touch point recorded last time;
步骤S1210，比较位移与位移阈值，当位移小于位移阈值时，则为连续触控；当位移大于或等于位移阈值时，则为非连续触控。Step S1210 , comparing the displacement with the displacement threshold. When the displacement is less than the displacement threshold, it is continuous touch; when the displacement is greater than or equal to the displacement threshold, it is discontinuous touch.
通过本发明提供的实施例可以判断在显示装置上发生的触控是否为连续触控，提高了定位触控点的精度。Through the embodiment provided by the present invention, it can be judged whether the touch on the display device is a continuous touch, which improves the accuracy of locating the touch points.
