Description

一种公共电极结构及其应用 技术领域
本发明涉及柔性显示面板技术领域，尤其是，其中的一种公共电极结构及其应用。
 背景技术
已知，目前业界的主要Incell触摸屏方案，都是将LCD面板中采用的公共电极（Vcom电极）切割成若干个小方块，作为触摸感应的电极。然后通过检测手指或者触控笔触摸时与无触摸时该电极与GND之间的电容变化，来识别触摸位置。
这其中，如图5所示，在Incell触摸屏方案中，所述Vcom电极在整体上会被切割成多个很小的方块形状的子电极10’，然后这些子电极10’在分别通过各自的通道（channel）走线20’与驱动IC模块30’电性连接。
而由于切割后的每个子电极10’的方块形状的尺寸会比较小，相应的，连接这些方形子电极10’的通道走线20’，对应所述子电极10’的尺寸形状也就只能更为细小。因此，这也就使得这些通道走线20’对于静电防护的能力一般。
进一步的，在已知的Incell触摸屏方案的显示面板的工艺制程中，所述Vcom电极上方是无法镀阻抗较小的ITO层来做静电防护。因此，上述通道线细小以及无ITP层两相结合，使得业界常见的这种Incell模组结构的触控屏方案的静电防护能力较弱。
因此，确有必要来开发一种新型的公共电极结构，来克服现有技术的缺陷。
 技术问题

进一步的，在不同实施方式中，其中所述子电极上设置有2个或以上数量的尖角，这些尖角为相互连续设置在所述子电极上。
进一步的，在不同实施方式中，其中所述子电极上设置有2个或以上数量的尖角，这些尖角为相互间隔设置在所述子电极上。
