具体实施方式
以下将参照附图更详细地描述本发明的各种实施例。在各个附图中，相同的元件采用相同或类似的附图标记来表示。为了清楚起见，附图中的各个部分没有按比例绘制。
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。
图1示出了根据现有技术提供的触控屏的感应电极层的示意图。
如图1所示，触摸屏的感应电极层100以圆形为例。感应电极层100包括多个感应电极，其中图中每个感应电极中标注的百分比为每个感应电极的面积与参考面积的比值，其中参考面积例如为该感应电极层100中各个感应电极的理想面积。其中感应电极的面积与自身的初始电容值成正比。
进一步地，触摸屏的感应电极层100包括通过均匀分割得到的位于感应电极层中间区域的多个方形的感应电极110和通过异形分割得到的位于感应电极层周边区域的多个异形的感应电极120。其中，感应电极层100中间区域的4*4阵列中的多个感应电极110的面积均为参考面积的111.11％，即分布均匀。中间区域的4*4阵列外围的多个方形感应电极110的面积均为参考面积但与中间区域的4*4阵列中的感应电极的面积不同，两者之间的初始电容值的差距采用软件补偿。位于感应电极层100周边区域的异形的各感应电极120之间存在面积差异，并且与位于感应电极层100中间区域的感应电极之间也存在面积差异，进而感应电极层100中各感应电极之间的初始电容值的一致性差，需要通过软件算法补偿。
图2示出了根据本发明实施例提供的触控屏的感应电极层的示意图。
为适应需求，触摸屏的感应电极层的形状可以为方形、多边形或者圆形。其中Incell(内嵌式)触摸屏因其模组厚度薄、制作成本低被广泛应用。Incell触摸屏利用自电容或互电容的原理检测手指触摸的位置。Incell触摸屏中设置多个位于同层且相互独立的电容阵列，从而实现触控装置的多点触摸。本实施例中的触摸屏以incell结构的触摸屏为例进行说明，但本发明提供的触摸屏不限于此，例如还可以是其他单层结构的触摸屏。
如图2所示，触摸屏的感应电极层200以圆形为例。感应电极层200分为多个第一子区块区域以及至少一个基础区块区域，具体地，包括第一子区块220、230、240以及基础区块210。 第一子区块220中包括多个第二子区块221，第一子区块230中包括多个第二子区块231，第一子区块240中包括多个第二子区块241。第二子区块221、231、241分别与基础区块210的面积比值为99.5％～100.5％。其中上述第二子区块221的数量与第一子区块220的面积和基础区块210的面积相关，上述第二子区块231的数量与第一子区块230的面积和基础区块210的面积相关，上述第二子区块241的数量与第一子区块240的面积和基础区块210的面积相关。优选地，位于同一第一子区块中的多个第二子区块的面积相同。基础区块210作为参考的感应电极以得到多个面积与基础区块210相同或者差距极小的第二子区块作为感应电极，进而使得感应电极层200中的感应电极之间的初始电容值的一致性提高。
进一步地，基础区块210的形状和感应电极层200的形状相同。其基础区块210的几何中心与感应电极层200的几何中心重合。第一子区块220、230、240依次围绕基础区块210，在本实施例中，第一子区块220、230、240的形状为同心圆环形。感应电极层200中的第一子区块区域与基础区块区域之间的上述设置方式，使得分割感应电极层200的方式更简单，并且感应电极层200之间的感应电极的初始电容值的一致性更高。其中，感应电极层200之间的感应电极的初始电容值的一致性与各感应电极之间的面积比值相关，面积比值的精度与各第一子区块的面积和基础区块的面积相关。
在优选的实施例中，触控屏为指纹触摸屏时，感应电极的特征尺寸根据人体使用电子设备的手指接触尺寸设置，即，基础区块210的特征尺寸设为2mm～8mm。
图3示出了根据本发明实施例提供的分割触控屏感应电极层的方法流程图，图4a-4b示出了根据本发明实施例提供的分割触控屏感应电极层在各个步骤中的示意图。
本申请还提供一种触控屏初始值设置方法，因在本申请中，以感应电极的面积与感应电极的初始电容值相关为主要考虑因素。因此该方法主要涉及分割触控屏的感应电极层。以下以感应电极层为圆形为例进行具体说明。
如图3所示，分割触控屏感应电极层的方法包括如下步骤：
步骤S01：将感应电极层分为多个第一子区块和至少一个基础区块。参见图4a，将感应电极层200分为第一子区块220、230、240以及基础区块210。基础区块210作为参考的感应电极。
进一步地，基础区块210的形状与感应电极层200的形状形同皆为圆形，其基础区块210的几何中心与感应电极层200的几何中心重合。第一子区块220、230、240依次围绕基础区块210，在本实施例中，第一子区块220、230、240的形状为同心圆环形，其中上述得到的4个圆形从圆心朝外半径依次为a、b、c、d。
在替代的实施例中，感应电极层200的形状可以是多边形、方形等，对应的基础区块210的形状可以是多边形、方形等，而第一子区块围绕基础区块一次设置，其形状为同心环形，该 环形的边缘形状与感应电极层200的形状相同。
步骤S02：将所述第一子区块分割为多个第二子区块。参见图4b，基于每个第一子区块的面积与基础区块210的面积获得该第一子区块包含第二子区块的数量，进而基于该第一子区块包含第二子区块的数量以基础区块210的中心为参照将该第一子区块分割为多个第二子区块。基础区块210和第二子区块作为感应电极，第二子区块的面积与基础区块210的面积的比值为99.5％～100.5％，以使得第二子区块的初始电容值与基础区块210的初始电容值的比值为99.5％～100.5％。
进一步地，依次将第一子区块210分割为多个第二子区块221，以及将第一子区块220、230、240分割为多个对应的第二子区块。进而得到如图2所示的感应电极层200。
具体地，以下是其中一种分割感应电极层的实施方法。其中，基础区块210的面积为S1＝πa 2，第一子区块220的面积为S2＝πb 2-πa 2，第一子区块230的面积为S3＝πc 2-πb 2，第一子区块240的面积为S4＝πd 2-πc 2。其中将第一子区块220平均分割为m份，使得S2/m＝S1，将第一子区块230平均分割为n份，使得S3/n＝S1，将第一子区块240平均分割为q份，使得S4/q＝S1。由于m，n，q均为实际要分割的作为感应电极的第二子区块的数量，所以需要取值为整数。综上，可以得到各第一子区块、基础区块的半径与第二子区块可分割的数量之间的关系，即，
Figure PCTCN2020136372-appb-000001
Figure PCTCN2020136372-appb-000002
优选地，作为一个感应电极的基础区块210的半径根据人体使用电子设备的手指接触尺寸设置，例如，基础区块210的半径a为5mm。内圆不作分割，基础区块210的面积为S1＝78.5398mm 2。并且m，n，q太小时环形的第一个子区块中仅有很少的识别区域，其感应精度差。
本实施例中，以令m＝8，即第一子区块220中分割得到8个第二子区块221作为感应电极，得到b＝15mm，进而第一子区块220的面积为S2＝78.5398mm 2。令n＝10，即第一子区块230中分割得到10个第二子区块231作为感应电极，可得到c≈21.8mm，进而第一子区块230的面积为S3＝78.6253mm 2。令q＝16，即第一子区块240中分割得到16个第二子区块241作为感应电极，可得d≈29.6mm；进而第一子区块240的面积为S4＝78.7205mm 2。本实施例中，S1＝S2面积为100％时，S3面积为100.1％，S4面积为100.2％，即，本实施例中感应电极的面积之间的比值趋向于100％，进而感应电极层200中个感应电极的初始电容值的一致性高，无需软件算法进行补偿，节约了成本和资源。在替代的实施例中，m，n，q的取值也可以根据实际需求进行调整，来实现需求的精度。
本申请还提供一种显示装置，包括上述提供的触摸屏，在该显示装置中触摸屏的感应电极可以复用为显示电极。显示装置包括但不限于LED显示装置、液晶显示装置、micro LED显示装置、OLED显示装置。
本申请还包括一种电子设备，包括上述提供的触摸屏。该电子设备包括但不限于手机、计算机、平板电脑、可穿戴电子设备。
依照本发明的实施例如上文所述，这些实施例并没有详尽叙述所有的细节，也不限制该发明仅为所述的具体实施例。显然，根据以上描述，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本发明的原理和实际应用，从而使所属技术领域技术人员能很好地利用本发明以及在本发明基础上的修改使用。本发明仅受权利要求书及其全部范围和等效物的限制。
