背景技术Background technique

目前，手机、平板电脑等显示类电子产品，不仅要满足人们的工作需求，还要满足人们的娱乐需求，为使人们享受身临其境的显示效果，大屏幕化成为一种发展趋势。然而，屏幕较大的显示类电子产品，对于其放置空间要求较为严格，造成携带不便。面对大屏幕的显示类电子产品携带不便的问题，柔性的显示类电子产品(以下简称柔性显示装置)应运而生。At present, display electronic products such as mobile phones and tablet computers must not only meet people's work needs, but also meet people's entertainment needs. In order to enable people to enjoy immersive display effects, large screens have become a development trend. However, display electronic products with large screens have relatively strict requirements on their storage space, which causes inconvenience in carrying. Facing the problem of large-screen display electronic products being inconvenient to carry, flexible display electronic products (hereinafter referred to as flexible display devices) have emerged as the times require.

现有的一种柔性显示装置包括柔性显示屏和两个板状支架，其中，两个板状支架通过铰接连接且两个板状支架均与柔性显示屏固定连接。当需要携带上述柔性显示装置出行时，通过两个板状支架的对折可实现该柔性显示装置的折叠，携带十分方便。然而，当该柔性显示装置处于折叠状态时，柔性显示屏的可弯曲部分弯成死弯，导致柔性显示屏的弯曲部分容易出现褶皱。当褶皱明显时会严重影响显示质量，需要更换柔性显示屏，导致上述柔性显示装置中的柔性显示屏的使用寿命短。An existing flexible display device includes a flexible display screen and two plate-shaped supports, wherein the two plate-shaped supports are hingedly connected and both plate-shaped supports are fixedly connected to the flexible display screen. When it is necessary to carry the above-mentioned flexible display device for travel, the folding of the flexible display device can be realized by folding the two plate-shaped brackets in half, which is very convenient to carry. However, when the flexible display device is in a folded state, the bendable portion of the flexible display screen is bent into a dead bend, which causes wrinkles to easily appear on the bendable portion of the flexible display screen. When the wrinkles are obvious, the display quality will be seriously affected, and the flexible display screen needs to be replaced, resulting in a short service life of the flexible display screen in the flexible display device.
