具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一 部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
目前，触摸屏多采用单层多点触摸屏结构，如图1所示，原因在于单层多点触摸屏结构的成本和厚度优势，但是由于其走线曲折、不同通道之间的走线长短差距非常大，造成信号衰减非常严重，导致触摸屏的触控灵敏性较低。此外，单层多点触摸屏结构的图案(pattern)中也有走线通道，上述信号的衰减又将导致芯片(IC)无法判别图案(pattern)和走线之间的电压变化，放大了信号之间的干扰，从而导致误触和不灵敏现象的发生，基于此，本申请实施例提供的一种触控面板、触摸屏及显示装置，可以缓解现有技术中存在的触控灵敏性较低的技术问题，提高触控的灵敏性。
为便于对本实施例进行理解，首先对本申请实施例所公开的一种触控面板进行详细介绍。
实施例一：
本申请实施例提供了一种触控面板，可应用于触摸屏，具体应用于电容式触摸屏。
如图2所示，该触控面板包括基材100以及设置在所述基材上的触控电极，触控面板分为至少两个分区200，相邻的分区中的触控电极分别设置在基材的相反的两个面上。
具体的，基材可以选用玻璃等刚性基材或PI(Polyimide，聚酰亚胺)等柔性基材，触控电极可以选用氧化物导电膜。
分区内的触控电极在该分区内进行走线。具体的，当触控面板分为两个相邻的分区时，其中，这两个分区内的触控电极分别在其所在的分区内通过内部走线通道进行连接；当触控面板分为至少三个分区时，必然存在至少两个位于同一面的两个不同的分区，此时，同一面的至少两个不同的分区之间的触控电极可以通过外部连接线进行连接。通过划分分区以及分区连接的走线方式，降 低走线的距离差异，防止由于线路过长而导致的信号功率衰减以及严重的信号干扰的问题，有利于提高触控灵敏性。
需要说明的是，分区的数量可以根据实际要控制的触摸屏的信号衰减量来确定，即可以通过合理的分屏数确保信号的衰减在合理的范围内，提高触控的灵敏性。
本申请实施例提供的触控面板包括基材以及设置在基材上的触控电极，触控面板分为至少两个分区，相邻的分区中的触控电极分别设置在上述基材相反的两个面上。该触控面板通过采用分屏的方式，将信号的衰减控制在预设的范围内，提高了触控的灵敏性。而且该触控面板采用分区走线的方式，能够减少边框走线长短差距，从而防止由于线路过长而导致的信号衰减严重，有效降低信号干扰，缓解了现有的触摸屏存在触控灵敏性较低的问题，提高了触控灵敏性。此外，该触控面板可以使用阻抗大的基材，避免现有触摸屏为了提高灵敏性采用降低膜材阻抗导致显示效果降低的问题，能够提高触摸屏的穿透率，提高了显示效果。
进一步的，在同一个分区内的触控电极仅设置在基材的一个面上，换言之，以一个分区为例，该分区的触控电极仅设置在基材的一个面上，基材的另一面没有设置该分区的触控电极，即该分区的设置在基材的另一面的触控电极已经被清空。
进一步的，上述的分区均设置于触控面板的视窗区(VA区)，即对触控面板的视窗区进行分屏。
进一步的，上述的触控电极呈菱形、条形或网格形。本实施例中，触控电极呈菱形。
考虑到如何提高显示效果，进一步的，这里的基材的材质为玻璃。
鉴于在氧化物导电膜中，掺Sn的In 2O 3(即ITO)膜的透过率最高和导电性能最好，而且容易在酸液中蚀刻出细微的图形，其中透光率达90％以上。进一 步的，所述触控电极的材质为ITO。ITO中其透光率和阻值分别由In 2O 3与SnO 2之比例来控制，通常SnO 2:In 2O 3＝1:9。
通过将基材的材质选为玻璃，触控电极的材质选用ITO，使得屏幕的穿透率较高，从而提高触摸屏的显示效果。
为了便于理解，结合图3对本实施例提供的触控面板进行简要说明：
该触控面板包括三个分区，其中，两个分区位于基材的正面(该两个分区的触控电极仅设置在基材的正面)，另一个分区位于基材的反面(即该另一个分区的触控电极仅设置在基材的反面)；基材的材质为玻璃，触控电极的材质为ITO，触控电极呈菱形。
图4示出了分屏前后的列触控电级的走线长度对比图，其中(a)分屏前的列触控电极的走线长度，(b)分屏后的列触控电极的走线长度，从图4可以看出，通过将触控面板分屏，极大的减少了走线长度。
应当注意的是，在基材反面的分区的设置于基材正面的触控电极(或者说图案化的ITO)已被清空，以防止信号被屏蔽而无法让手指触发信号被感应。
进一步的，如图5、图6和图7所示，所述触控电极包括若干行触控电极300和若干列触控电极400。
具体的，每个分区包含行触控电极300(又称为Tx电极或X轴电极)和列触控电极400(又称为Rx电极或Y轴电极)两种；行触控电极和列触控电极呈菱形。其中，当分屏区域为两个时，分屏区域内的行触控电极和列触控电极分别在该分屏区域内通过内部走线通道走线连接；当分屏区域为至少三个时，每个分屏区域内的行触控电极和列触控电极分别在该分屏区域内通过内部走线通道走线连接，同一面的分屏区域之间的行触控电极和列触控电极分别通过外部连接线连接。
在一实施例中，每个分区的左右两侧边缘设置有第一走线区(又称为边缘走线区)；其中，用于连接所述行触控电极的若干条行触控电极线301(又称 为第一内部走线通道)汇集于所述第一走线区；用于连接所述列触控电极的若干条列触控电极线401(又称为第二内部走线通道)汇集于所述第一走线区。
进一步的，若干行触控电极从分区左侧边缘的第一走线区走线，其他若干行触控电极从分区右侧边缘的第一走线区走线；若干列触控电极从分区左侧边缘的第一走线区走线，其他若干列触控电极从分区右侧边缘的第一走线区走线。换言之，上述第一走线区包括左侧走线区和右侧走线区；行触控电极包括若干左侧走线的行触控电极和若干右侧走线的行触控电极；同样的，列触控电极包括若干左侧走线的列触控电极和若干右侧走线的列触控电极。
具体的，以分区宽度(沿X方向)的1/2处作为分界线，左半部分的行触控电极从第一走线区的左侧走线，右半部分的行触控电极从第一走线区的右侧走线；左半部分的列触控电极从第一走线区的左侧走线，右半部分的列触控电极从第一走线区的右侧走线。
需要指出的是，鉴于分界线处的行触控电极(或者列触控电极)被一分为二的情况，此时，分界线处的行触控电极(或者列触控电极)既可以从左侧的第一走线区走线，也可以从右侧的第一走线区走线，对此本申请不作限制。
在另一实施例中，每个分区的中部(具体为纵向轴线位置)设置有第二走线区(又称为中部走线区)；其中，用于连接行触控电极的若干条行触控电极线汇集于第二走线区；和/或，用于连接列触控电极的若干条列触控电极线汇集于第二走线区。
具体的，第二走线区右侧的行触控电极从第二走线区走线，第二走线区左侧的行触控电极从第二走线区走线；同样的，第二走线区右侧的列触控电极从第二走线区走线，第二走线区左侧的列触控电极从第二走线区走线。
进一步的，每个分区的顶端或底端边缘设置有第三走线区，每个分区的列触控电极经第三走线区连接至栅极驱动电路。
需要说明的是，第三走线区的宽度不大于第二走线区的宽度。
在本实施例中，参照图6和图7，分区设置有第一走线区500和第二走线区600，第一走线区设置于该分区的边缘，第二走线区设置于该分区的纵向轴线位置；
其中，若干行触控电极从分区左侧边缘的第一走线区走线，若干行触控电极从分区右侧边缘的第一走线区走线；若干行触控电极从第二走线区走线；若干列触控电极从分区左侧边缘的第一走线区走线，若干列触控电极从分区右侧边缘的第一走线区走线；若干列触控电极从第二走线区走线。
具体的，第一走线区设置于分区的左右两侧边缘，第二走线区设置于分屏区域的宽度(沿X轴方向)的1/2处且垂直于X轴，相邻两行触控电极中的其中一行的左半部分的行触控电极从第一走线区的左侧走线，相邻两行触控电极中的其中一行的右半部分的行触控电极从第一走线区的右侧走线；相邻两行触控电极中的另一行的左半部分的行触控电极从第二走线区走线，相邻两行触控电极中的另一行的右半部分的行触控电极从第二走线区走线；同一列的列触控电极依次串联连接，每一列的列触控电极线呈蛇形(或者称毛毛虫形)，列触控电极线沿行触控电极的边缘走线或者说列触控电极线的走线紧贴行触控电极的边缘。
具体的，列触控电极线包括依次连接的第一折线部、第二直线部、第三折线部和第四直线部，其中第一折线部和第三折线部相互平行，第二直线部和第四直线部相互平行，第一折线部和第二直线部相互垂直，第一折线部和第三折线部沿相邻行的行触控电极边缘呈折线形，第二直线部位于第一走线区，且呈直线形；第四直线部位于第二走线区且呈直线形。左半部分的列触控电极的一端从第一走线区的左侧走线，左半部分的列触控电极的另一端从第二走线区走线；右半部分的列触控电极的一端从第一走线区的右侧走线，右半部分的列触控电极的另一端从第二走线区走线。
需要指出的是，鉴于第二走线区附近的行触控电极(或者列触控电极)被一分为二的情况，此时，分界线处的行触控电极(或者列触控电极)既可以从 左侧的第一走线区走线，也可以从右侧的第一走线区走线，对此本申请不作限制。
如图6所示，本实施例中，分区的底端边缘设置有第三走线区700，分区的列触控电极经第三走线区连接至栅极驱动电路。
第三走线区700的宽度小于第二走线区的宽度，换言之，分区的底端走线不大于图案中间的走线宽度，其中图案中间的走线宽度可以是一个能够避免触摸盲区的阈值。
进一步的，当分屏区域的数量大于2时，可以将同一面的不同分区的行触控电极和列触控电极分别相对应的连接起来，以减小边框的宽度。
具体的，参照图8，所述触控面板包括三个分区，其中，间隔设置的两个分区处于该基材的同一面(正面)，一个分区处于该基材的另一面(反面)，一个分区将两个分区分隔开，基材的与该反面的一个分区相对的一面(即两个分区所处的基材的正面)上无触控电极(即ITO被清空)。其中，同一面的两个分区中相对应的行触控电极通过第一外部走线相连接；同一面的两个分区的相对应的列触控电极通过第二外部走线相连接。
需要指出的是，第一外部走线和/或第二外部走线沿分区的外侧边缘排布在基材之外。
如图8所示，同一面的两个分区的左半部分中的相对应的行触控电极：Tx01与Tx11、Tx02与Tx12、Tx03与Tx13、Tx04与Tx14分别通过第一外部走线相连。这样分屏距离足够远且大于一个手指的间距，所以不会对触摸产生不良影响，提高了触控效果。
同时，同一面的两个分区中左半部分中的相对应的行触控电极：Rx01与Rx11、Rx02与Rx12、Rx03与Rx13、Rx04与Rx14通过第二外部走线相连，起到减小RX走线通道的数量。
应当理解的是，同一面的两个分区的右半部分中的相对应的行触控电极：Tx05与Tx15、Tx06与Tx16、Tx07与Tx17、Tx08与Tx18分别通过第一 外部走线相连；同一面的两个分区中右半部分中的相对应的行触控电极：Rx05与Rx15、Rx06与Rx16、Rx07与Rx17、Rx08与Rx18通过第二外部走线相连。
需要说明的是，反面的分区的走线与正面的分区的走线相似，区别仅在于在基材反面的分区内的触控电极在反面进行走线。
如图9所示，本实施例中所有的列触控电极线的图案走线宽度为0.5200mm，分区列触控电级的底端走线宽度(简称分屏的底端走线)为0.7359mm，第二走线区宽度(即图案中间的走线宽度)为1.0935mm。可见，由于不用再采用双边出线的方案，故可以保证分屏的底端走线不大于图案中间的走线宽度。
