Description
技术领域
本发明涉及显示技术领域,尤其涉及一种阵列基板及显示面板。
背景技术
高屏占比的电子设备越来越被消费者所青睐。屏占比是指屏幕与电子产品前面板面积的相对比值,它是电子产品外观设计上比较容易获得视觉好感的参数。目前电子产品的状况是屏占比较小,特别是上下边框因听筒、摄像头、HOME键占据了较大的屏占比,导致在外形的前提下,屏占比利用率较低。如何在传统电子产品外形整体尺寸不变的前提下,加大屏占比,减小上下手机边框,以给消费者更好的视觉体验,已成为当前的重要研究方向之一。
为了实现更高屏占比,屏下摄像头是一种可行且有效的方案但是如何实现拍照与显示共存是一项技术难题,尤其是显示面板中存在多种走线,且多种走线形成规律性排布。在高显示密度(PPI)的显示面板中,走线的线宽为微米量级,极为接近可见光的波段,可见光透过显示面板后极容易产生干涉和衍射,对于要求高显示精度的摄像头成像来说,存在极大的干扰风险。因此,如何避免透过光线的干涉、衍射,导致对摄像头的成像造成干扰,是目前急需要解决的重要问题。

进一步地,所述非走线膜层还包括第三膜层,所述第三膜层设置在所述非走线层的顶部,所述第一膜层与所述第三膜层相邻设置,且位于所述第三膜层的底部,所述第二膜层与所述第一膜层相邻设置,且位于所述第一膜层的底部。
进一步地,所述非走线膜层还包括第三膜层,所述第一膜层设置在所述非走线层的顶部,所述第二膜层与所述第一膜层相邻设置,且位于所述第一膜层的底部,所述第三膜层与所述第二膜层相邻设置,且位于所述第二膜层的底部。
进一步地,在所述非走线层的最底层上设置通孔,所述通孔用于增强所述非走线层的透光性。

本发明的优点在于,通过设置一组合结构(第一膜层和第二膜层),使得产生干涉和衍射的光线从光密介质区(第一膜层)射向光疏介质区(第二膜层),入射角较大的光线产生全反射,并且入射角较小的光线,即使未能够被全反射,通过此组合结构时,折射角也会增大,因此能够减少发生干涉和衍射的光线进入摄像头,使屏下摄像头不受干涉、衍射光干扰成像。另外通过设置通孔,以增加了显示面板的透光性,使得摄像头拍摄效果更好。

本发明实施例二的优点在于,通过设置一组合结构(第一膜层和第二膜层),使得产生干涉和衍射的光线从光密介质区(第一膜层)射向光疏介质区(第二膜层),入射角较大的光线产生全反射,即使入射角较小的光线未能够被全反射,通过此组合结构时,折射角也会增大,因此能够减少发生干涉和衍射的光线进入摄像头,使屏下摄像头不受干涉、衍射光干扰成像。
