Description

自电容式触摸屏结构、内嵌式触摸屏以及液晶显示器 技术领域
本发明涉及触控技术领域,尤其涉及一种自电容式触摸屏结构、内嵌式触摸屏以及液晶显示器。
背景技术
触摸显示屏作为一种输入媒介,是目前最简单、方便的一种人机交互方式，因此触摸显示屏越来越多地应用到各种电子产品中。基于不同的工作原理以及传输信息的介质，触摸屏产品可以分为四种：红外线触摸屏、电容式触摸屏、电阻触摸屏和表面声波触摸屏；其中电容式触摸屏由于具有寿命长、透光率高、可以支持多点触控等优点成为目前主流的触摸屏技术。电容式触摸屏包括表面电容式和投射电容式，其中投射电容式又可以分为自电容式和互电容式。对于自电容触摸结构，由于其触控感应的准确度和信噪比比较高，因而受到了各大面板厂家青睐。
目前，自电容触摸结构利用自电容的原理实现检测手指触摸位置，具体为：在触摸结构中设置多个同层设置且相互绝缘的自电容电极，当人体未触碰屏幕时，各自电容电极所承受的电容为一固定值，当人体触碰屏幕时，触碰位置对应的自电容电极所承受的电容为固定值叠加人体电容，触控侦测芯片在触控时间段通过检测各自电容电极的电容值变化可以判断出触控位置。
图1为现有的一种自电容式触摸屏结构的示意图，如图1所示的，该自电容式触摸屏结构包括M行×N列的自电容电极Rxy(R11～RM1～R1N～RMN)以及触控侦测芯片1，每一个自电容电极Rxy需要通过单独的连接走线Lyx与触控侦测芯片1连接。具体地，自电容电极Rxy和连接走线Lyx为异层设置，且自电容电极Rxy与对应的连接走线Lyx通过过孔2电性连接，每一列自电容电极R1y～RMy分别由一组连接走线Ly1～LyM按顺序依次连接。例如图1中的第一列自电容电极R11～RM1，按照从下到上的顺序，对应的一组连接走线L11～L1M从左到右的顺序，每根连接走线L1x均与相应的一个自电容电极Rx1相连接，且与其他的自电容电极相断开，实现每个自电容电极Rx1的信号单独控制。即，每根连接走线L1x接 到相应的自电容电极Rx1前均不与前面的自电容电极R11～R(x-1)1相连，连接相应的自电容电极Rx1后该连接走线L1x将不与后面的自电容电极R(x+1)1～RM1继续连接。具体地，该列自电容电极R11～RM1中的第一个自电容电极R11由该组连接走线L11～L1M中的第一根连接走线L11连接到触控侦测芯片1，第二个自电容电极R21由第二根连接走线L12连接到触控侦测芯片1，以此类推，第M个自电容电极RM1由第M根连接走线L1M连接到触控侦测芯片1。其中，以上的符号标示中，x＝1、2、3、…、M，y＝1、2、3、…、N。
如上所述的自电容式触摸屏结构中，由于每一列自电容电极R1y～RMy分别由一组连接走线Ly1～LyM按顺序依次连接，对于同一列的自电容电极R1y～RMy，对应的一组连接走线Ly1～LyM的长度呈递增的形式，离触控侦测芯片1越远的自电容电极RMy，对应的连接走线LyM越长。最终，从整个触摸屏结构的显示情况来看，一组连接走线Ly1～LyM的末端会呈现出斜线mura，如图1中的A区域，影响了显示品质。
发明内容
鉴于现有技术存在的不足，本发明提供了一种自电容式触摸屏结构，通过对其中的自电容电极的连接走线方式进行改进，减小了现有技术中因连接走线问题引起的斜线mura，提高了产品显示品质。
为了实现上述目的，本发明采用了如下的技术方案：
一种自电容式触摸屏结构，包括阵列设置的相互绝缘的多个自电容电极以及触控侦测芯片，每一自电容电极通过一连接走线与所述触控侦测芯片连接，所述自电容电极与对应的连接走线通过至少一过孔电性连接；其中，将连接于同一列自电容电极的一组连接走线分为奇数组和偶数组，奇数组连接走线从该列自电容电极的一端依次连接到对应的自电容电极，偶数组连接走线从该列自电容电极的另一端依次连接到对应的自电容电极。
其中，所述自电容电极与所述连接走线为异层结构设置。
其中，所述自电容电极的形状为方形。
其中，所述过孔的数量为3～5个。
其中，所述触控侦测芯片位于所述多个自电容电极的下端，每一列自电容电极包括从下到上的第1至第M个自电容电极，连接于该列自电容电极的一组 连接走线包括从左到右的第1至第M跟连接走线，其中，第1、3、5、…根连接走线依次连接到第1、2、3、…个自电容电极，第2、4、6、…根连接走线依次连接到第M、M-1、M-2、…个自电容电极。

具体实施方式
如前所述，本发明的目的是为了改善了现有的自电容式触摸屏结构中，由 于连接到同一列自电容电极的一组连接走线的长度递增的形式，其引起的斜线mura的问题，提出了一种自电容式触摸屏结构。该自电容式触摸屏结构包括阵列设置的相互绝缘的多个自电容电极以及触控侦测芯片，每一自电容电极通过一连接走线与所述触控侦测芯片连接，所述自电容电极与对应的连接走线通过至少一过孔电性连接；其中，将连接于同一列自电容电极的一组连接走线分为奇数组和偶数组，奇数组连接走线从该列自电容电极的一端依次连接到对应的自电容电极，偶数组连接走线从该列自电容电极的另一端依次连接到对应的自电容电极。
该自电容式触摸屏结构中，通过对连接走线布局的改进，对于连接到同一列自电容电极的一组连接走线，采用长度较短的连接走线和长度较长的连接走线交替设置的布局方式，有效减少了斜线mura的问题，提高了产品显示品质。
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详细地描述，显然，所描述的实施例仅仅是本发明一部分实例，而不是全部实施例。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的前提下所获得的所有其他实施例，都属于本发明保护范围。
实施例1
本实施例提供了一种自电容式触摸屏结构。如图2所示，该自电容式触摸屏结构包括M行×N列的相互绝缘的自电容电极Rxy(R11～RM1～R1N～RMN)以及触控侦测芯片10，每一个自电容电极Rxy需要通过单独的连接走线Lyx与触控侦测芯片10连接。具体地，本实施例中，自电容电极Rxy的形状为方形，自电容电极Rxy和连接走线Lyx为异层设置，自电容电极Rxy和连接走线Lyx的材料均为ITO，且自电容电极Rxy与对应的连接走线Lyx通过过孔20电性连接。本实施例中，过孔20的数量为1个，在另外的一些实施例中，为了提高自电容电极Rxy与对应的连接走线Lyx电连接的性能，过孔20的数量也可以设置为多个，比较优选的是3～5个。其中，以上的符号标示中，x＝1、2、3、…、M，y＝1、2、3、…、N。
在本实施例的自电容式触摸屏结构中，如图2所示的，触控侦测芯片10位于多个自电容电极Rxy的下端，每一列自电容电极包括从下到上的第1至第M个自电容电极R1y～RMy，连接于该列自电容电极R1y～RMy的一组连接走线包括从左到右的第1至第M跟连接走线Ly1～LyM，其中采用长度较短的连接走线Lyx和长度较长的连接走线Lyx交替设置的布局方式。具体地，以第一列自电容电极 R11～RM1为例，第一列自电容电极R11～RM1由第一组连接走线L11～L1M连接到触控侦测芯片10。其中，将该组连接走线L11～L1M分为奇数组和偶数组，奇数组连接走线包括第奇数根连接走线L11、L13、…，偶数组连接走线包括第偶数根连接走线L12、L14、…。其中，奇数组连接走线L11、L13、…从该列自电容电极R11～RM1的下端开始，依次连接到自电容电极R11、R21、…，偶数组连接走线L12、L14、…从该列自电容电极R11～RM1的上端开始，依次连接到自电容电极RM1、R(M-1)1、…。最后一根连接走线L1M则连接至该列自电容电极R11～RM1的中间位置的自电容电极。
由此，对于连接到同一列自电容电极R11～RM1的一组连接走线L11～L1M，实现了长度较短的连接走线和长度较长的连接走线交替设置的布局方式(例如L11和L12、L13和L14、…相互交替)，有效减少了斜线mura的问题，提高了产品显示品质。
实施例2
本实施例与实施例1不同的是，奇数组连接走线与偶数组连接走线的连接顺序与实施例1中的正好相反。如图3所示的，还是以第一列自电容电极R11～RM1为例，第一列自电容电极R11～RM1由第一组连接走线L11～L1M连接到触控侦测芯片1。其中，将该组连接走线L11～L1M分为奇数组和偶数组，奇数组连接走线包括第奇数根连接走线L11、L13、…，偶数组连接走线包括第偶数根连接走线L12、L14、…。其中，奇数组连接走线L11、L13、…从该列自电容电极R11～RM1的上端开始，依次连接到自电容电极RM1、R(M-1)1、…，偶数组连接走线L12、L14、…从该列自电容电极R11～RM1的下端开始，依次连接到自电容电极R11、R21、…。最后一根连接走线L1M则连接至该列自电容电极R11～RM1的中间位置的自电容电极。由此，本实施例中对于连接到同一列自电容电极R11～RM1的一组连接走线L11～L1M，实现了长度较短的连接走线和长度较长的连接走线交替设置的布局方式(例如L11和L12、L13和L14、…相互交替)，有效减少了斜线mura的问题，提高了产品显示品质。
实施例3
如图4所示，本实施例提供了一种内嵌式触摸屏200，其包括上基板201、下基板202以及设置于上基板201和下基板202之间的液晶层203。进一步地，该内嵌式触摸屏200还包括如实施例1或实施例2提供的自电容式触摸屏结构204；其中，自电容式触摸屏结构204中的自电容电极和连接走线均设置于所述 上基板201面向所述下基板202的一侧。
如图4中，本实施例还提供了一种液晶显示器，其包括如上所述的内嵌式触摸屏200以及背光模组100，内嵌式触摸屏200与背光模组100相对设置，所述背光模组100提供显示光源给所述内嵌式触摸屏200，以使所述内嵌式触摸屏200显示影像。
综上所述，本发明实施例中提供的自电容式触摸屏结构以及包含该自电容式触摸屏结构的内嵌式触摸屏和液晶显示器，通过对其中的自电容电极的连接走线方式进行改进，对于连接到同一列自电容电极的一组连接走线，采用长度较短的连接走线和长度较长的连接走线交替设置的布局方式，有效减少了现有技术中由于一组连接走线的长度递增的形式引起的斜线mura的问题，提高了产品显示品质。
