Description

一种可折叠显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种可折叠显示装置。
 背景技术
目前柔性OLED以其可弯曲以及可挠曲受到广泛关注。目前，搭载柔性OLED的主流可折叠显示装置的折叠方式为内折和外折。采用内折叠方式的显示装置中，显示装置弯折后，由于支撑柔性显示屏的支撑机构的内表面尺寸减小，导致支撑机构的内表面尺寸与柔性显示屏的尺寸不匹配，弯折的过程中，支撑机构会对柔性显示屏位于弯折区的部分产生挤压，容易导致柔性显示屏失效甚至损坏。
 技术问题
现有的可折叠显示装置在内折叠的过程中，支撑机构会对柔性显示屏位于弯折区的部分产生挤压，从而导致柔性显示屏失效甚至损坏。
 技术解决方案

在一些实施例中，所述支撑座包括上支撑部、下支撑部以及连接上支撑部和下支撑部的连接部，所述第一传动部位于所述上支撑部与所述下支撑部之间。
在一些实施例中，所述折叠机构处于展开状态时，所述上支撑部的外表面与所述支座的表面齐平。
在一些实施例中，所述上支撑部的外表面的形状大小与所述开口的形状大小相匹配。
在一些实施例中，所述柔性显示屏具有固定区和弯折区，所述折叠机构处于展开状态时，所述固定区贴附固定于所述支座上，所述弯折区可分离的设置于所述上支撑部上。

 有益效果
折叠机构处于展开状态时，柔性显示屏也处于展开状态，利用支撑座对柔性显示屏的弯折区的部分进行支撑；折叠机构处于折叠状态时，同时柔性显示屏被弯折，折叠折叠机构的过程中，两个支座绕第一方向转动相互靠近，通过第一传动部和第二传动部的相互配合，带动支撑座沿远离开口的方向滑动，为柔性显示屏的弯折区的部分让出空间，从而避免柔性显示屏弯折的过程中支撑座对柔性显示屏弯折的部分产生挤压导致柔性显示屏失效甚至损坏。
