Description

光电功能组件、包含光电功能组件的触摸显示屏和电子装置
本申请要求于2023年5月25日提交到国家知识产权局、申请号为202310600408.1、发明名称为“光电功能组件、包含光电功能组件的触摸显示屏和电子装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及触控显示技术，特别涉及光电功能组件、包含该光电功能组件的触摸显示屏和电子装置。
背景技术
随着智能交互应用场景的普及，电容触摸、书写等功能被集成到显示屏内，亦或还会在屏幕表面进一步增加拓宽视角、减少反射或抗指纹等功能。业内通常的做法是，将单一功能的组件进行逐层贴合装配在一起。此类方式增加了产品的应用成本。比如，通常会将触摸屏与显示屏进行全贴合组装，即在触摸屏和显示屏之间填充透明胶体材料，好处是可以提高屏幕显示效果，缺点是制造成本较高，而且若成品不良很难返工。
因此，从业者提出将触摸屏直接贴近于显示屏表面的方式进行组装，也称为零贴合方式。虽然触摸屏与显示屏之间的距离有所减小，但仍然存在空气间隙，使得触摸屏界面存在光学反射的现象。
进一步地，特别是对于显示屏采用垂直配向(Vertical Alignment，VA)类型的液晶模组，当观察角度超过40度以上时，观察的图像亮度明显下降并影响观察效果，并且长时间观察会损害观察者视力。

按照本申请的一个方面，将电学功能层和光学功能层设置于同一基底上，由此可借助于光学功能层对入射至组件的光的散射作用，在扩大观看视角的同时抑制画面亮度的明显衰减，同时还可借助于电学功能层实现触摸交互。
基底可以由透光率较高的透明材料构成，例如聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)材料、聚碳酸酯(Polycarbonate，PC)或聚甲基丙烯酸甲酯(polymethylmethacrylate，PMMA)材料等，本申请对此不做限制。
