Description

一种屏下摄像头液晶屏幕
技术领域
本发明涉及屏下摄像头技术领域,具体为一种屏下摄像头液晶屏幕。
背景技术
随着电子技术的不断发展,摄像头在各种电子设备中的应用越来越广泛。然而,摄像头与周围环境外观不一致,很容易被观察到,很大程度影响了电子设备的美观。为了解决这个问题,屏下摄像头应运而生。屏下摄像头是将摄像头置于液晶显示器下方,可以大大提升电子设备的美观性并且增加摄像头放置位置的自由度的。然而,现有的液晶显示器的透过率较低,周期性液晶排列造成的衍射大大影响了屏下摄像头的成像质量。
通过分析人眼对颜色的感知发现,人眼对绿色比较敏感,所以一般拜耳阵列的G子像素是R和B子像素的和。最常见的模式是由Kodak提出的2*2模式,R,G,B,W四个子像素区呈“田字形”排列。按照理想情况,每个像素点有3个值,而实际上,R和B各只有1/4,G有1/2,因此,拜耳阵列得到的图像中,实际只有1/3的内容是真实的,其他都是根据先验知识插值得到。有鉴于此,本方案结合拜耳阵列的插值补偿方案及RGBW的设计,设计一种屏下摄像头液晶屏幕,其为基于拜耳阵列的RGBGW像素结构,从而实现屏下摄像头的高透过率,从而提高屏下摄像头的成像质量。
发明内容
本发明的目的在于提供一种屏下摄像头液晶屏幕,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种屏下摄像头液晶屏幕,包括液晶显示屏以及设置在液晶显示屏下方的摄像头,摄像头呈圆形设置,且其位于液晶显示屏下方顶部的居中位置处;
所述液晶显示屏上设有与摄像头位置对应的屏下显示区以及除屏下显示区以外的正常显示区;
屏下显示区设有若干组主像素区,每组主像素区包含五个子像素区,依次相邻的四个子像素区沿顺时针方向分别为R子像素区、G子像素区、B子像素区和G子像素区,此四个子像素中间为W子像素区。
屏下显示区中主像素区的密度大于正常显示区中主像素区的密度。
正常显示区包括若干组主像素区,该主像素区包括三个子像素区,包括从左至右依次设置的R子像素区、G子像素区和B子像素区。
与现有技术相比,本发明的有益效果是:本发明结合拜耳阵列的插值补偿方案及RGBW的设计,本发明基于拜耳阵列的RGBGW像素结构,从而实现屏下的摄像头的高透过率,从而提高屏下的摄像头的成像质量。在维持现有彩膜制作工艺流程的前提下,通过设计新型像素结构,有效提高屏下摄像头区域透过率。
