Flexible display device

Abstract

The present invention belongs to the display technological field and discloses a flexible display device. The flexible display device comprises a flexible substrate and a flexible-rigid conversion layer formed on one side of the flexible substrate, wherein the flexible-rigid conversion layer comprises a conversion thin film which can undergo flexible-grid conversion under the action of an electricfield and an electrode layer which is used for forming the electric field that drives the change of the conversion thin film. The elastic parameter of the conversion thin film of the flexible displaydevice provided by the invention can be switched under the action of the electric field, the conversion thin film can be switched to a rigid layer from a flexible layer, and therefore, the flatteningof the flexible substrate can be realized; and on the basis of the conversion of the conversion thin film, damage to the flexible substrate during a process of a plurality of times of repeated coiling and unfolding can be decreased, the service life of the display device can be prolonged, and the display quality of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device. Background technique [0002] Flexible display devices are flexible display devices made of flexible materials. Due to their excellent display properties such as flexibility and lightness, flexible display devices can be used in wearable devices, mobile devices, augmented reality and virtual technologies. Devices and other fields are considered to be the mainstream of the future display field. [0003] Flexible display devices are usually made into a structure that can be rolled or folded in a non-operating state and unfolded in an operating state. However, the substrate material of the flexible display device is easily damaged during the artificial curling / folding process, and will also undergo irreversible deformation after long-term folding / curling storage, resulting in creases or warping problems. However, the above-mentioned problems will cause ...

AI Technical Summary

Problems solved by technology

However, the substrate material of flexible display devices is easily damaged during the artificial curling / folding process, and irreversible deformation will occur after long-term folding / curling storage, resulting in creases or warping problems.

The above problems will cause problems such as unevenness of the substrate material after unfolding, which will affect the display effect of the display.

At the same time, the unevenness of the substrate will also affect the working characteristics and life of the internal structure of the display, reducing the reliability of the display
