本申请提供一种电子元件区域显示画面的显示面板，如图1所示，所述显示面板包括电子元件显示区1和标准显示区2（即电子元件对应区域1之外的所有显示区）。
所述电子元件显示区1为面板上方，大小、形状和位置不做固定，根据手机终端摄像头需要进行设计，一般电子元件区域1的大小（直径或长宽）为3~8mm，形状为圆形或矩形，也可以是其他满足需要的大小和形状。
图2所示为带有电子元件显示区的显示面板的局部结构示意图，电子元件显示区1的像素密度比标准显示区2的像素密度低，具体的电子元件显示区1与标准显示区2的像素密度比可根据面板透光率及显示效果需求进行确定。
通过降低像素密度，减少了电子元件显示区1内的像素电路金属走线、数据线金属走线和扫描线金属走线等不透光金属走线，同时集中剩余像素电路金属走线、数据线金属走线和扫描线金属走线布局为集中走线设计。如此，所述不透光金属集中走线形成如图2所示的疏松网格状，腾出无金属走线区域用于透光摄像。
