请一并参阅图1及图2，图1为本申请第一实施方式的电子装置的结构示意图；图2为本申请第一实施方式中触控显示模组的结构示意图。所述电子装置包括但不仅限于为智能手机、互联网设备(mobile internet device，MID)、电子书、便携式播放站(Play Station Portable,PSP)或个人数字助理(Personal Digital Assistant，PDA)等设备。
所述电子装置1包括触控显示模组10。所处触控显示模组10集成有显示功能及触控功能，所述触控显示模组10包括触控显示面板100。所述触控显示面板100包括第一像素区160a及第二像素区160b，所述第一像素区160a包括第一像素165a，所述第一像素165a的RC负载为第一负载，所述第二像素区160b包括第二像素165b，所述第二像素165b的RC负载为第二负载，所述第一负载不等于所述第二负载。所述第一像素区160a对应所述第一像素165a设置有第一电极111a，所述第二像素区160b对应所述第二像素165b设置有第二电极111b，所述第二电极111b与所述第一电极111a间隔设置。所述触控显示面板100包括显示模式，当所述触控显示面板100处于显示模式时，所述第一电极111a和所述第二电极111b电连接，所述第一电极111a及所述第二电极111b均为公共电极。本申请中提到的“第一像素区160a”、“第二像素区160b”中所用到的“第一”、“第二”仅用于描述目的，不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。相应地，本申请中提到的其他涉及“第一”、“第二”的描述，也仅仅用于描述目的，不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
进一步地，所述触控显示面板100还包括触控模式，当所述触控显示面板100处于触控模式时，所述第一电极111a和所述第二电极111b电性绝缘。当所述触控显示面板100处于显示模式时，所述触控显示面板100可以显示图像、文字、视频等。当所述触控显示面板100处于触控模式时，可以接受触控操作 指令。
若第一电极111a及第二电极111b电性绝缘，由于所述第一像素165a的第一负载与所述第二像素165b的第二负载的负载值不等，当所述第一电极111a与第二电极111b上加载相同的电压时，流经所述第一像素165a和所述第二像素165b的电流并不相同，从而使得所述第一像素165a及所述第二像素165b呈现出不同的亮度。即，触控显示面板100在显示画面的时候会出现亮度明暗不均的情况，从而降低了所述触控显示面板100的显示品质。而本申请在所述触控显示模组10处于显示模式时，将作为公共电极的第一电极111a及第二电极111b电连接，从而使得第一像素165a上加载的负载以及所述第二像素165b上加载的RC负载相同，当所述第一像素165a及所述第二像素165b上加载相同的电压时，流经所述第一像素165a及所述第二像素165b的电流相同，从而使得所述第一像素165a与所述第二像素165b呈现相同的亮度，进而提升了所述触控显示面板100的显示品质。
