Description

一种显示模组和显示装置、以及一种透明光学胶层结构
本申请要求在2017年07月05日提交中国专利局、申请号为201710543991.1、公开名称为“一种显示模组和显示装置、以及一种透明光学胶层结构”的中国专利申请的优先权，该申请的全部内容通过引用结合在本公开中。
技术领域
本公开涉及显示技术领域，特别是涉及一种显示模组和显示装置、以及一种透明光学胶层结构。
背景技术
随着显示技术的飞速发展，人们对显示装置的要求越来越高，目前，手机等显示装置都在向超薄、窄边框的方向发展，为实现超薄设计，显示装置的显示面板厚度越来越薄。
现有的显示模组一般包括依次设置的显示面板和盖板，其中，显示面板包括阵列基板、彩膜基板，以及填充于阵列基板和彩膜基板之间的液晶层。在显示面板的端子侧，阵列基板包括超出彩膜基板的边缘的电连接区，该电连接区用于设置驱动芯片和电路板，另外，一般在驱动芯片的两侧设置有泡棉，该泡棉支撑于盖板和阵列基板的电连接区之间，用于防止阵列基板的电连接区受压破损。
现有技术存在的缺陷在于，当对上述显示模组进行机械测试时，由于泡棉具有较好的弹性，受到挤压时极易变形，使泡棉的支撑作用欠佳，从而极易导致阵列基板的单层区破损；此外，现有填充泡棉工序需要人工作业，导致显示模组的生产效率较低。
