Method for manufacturing flexible display substrate

Abstract

The invention provides a method for manufacturing a flexible display substrate, and relates to the technical field of display. The method for manufacturing the flexible display substrate comprises steps of manufacturing a base layer on a carrier substrate; manufacturing a flexible underlayer substrate on the base layer; manufacturing electronic devices on the flexible underlayer substrate; and removing the base layer from the back of the flexible underlayer substrate so as to obtain the flexible display substrate. By the method for manufacturing the flexible display substrate, the back of the flexible underlayer substrate only contacts with the base layer, the phenomenon that bubbles damage the back of the flexible underlayer substrate is avoided, and accordingly plastic deformation of the flexible display substrate is avoided on the premise that the flatness of the flexible underlayer substrate is guaranteed and the flexible underlayer substrate is fixed accurately.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible display substrate. Background technique [0002] Flexible display (Flexible Display) technology has developed rapidly in the past ten years, which has driven flexible displays to make great progress in terms of screen size and display quality. Flexible displays, also known as rollable displays, are bendable and deformable display devices made of flexible materials and visible flexible panels. Whether it is the CRT that is on the verge of disappearing or the current mainstream LCD, they all belong to the traditional rigid display in essence. Compared with ordinary rigid displays, flexible displays have many advantages: impact resistance and stronger shock resistance; light weight, small size, and more convenient to carry; the tape-and-roll process similar to the newspaper printing process is used, and the cost is lower. [0003] Although th...

[0004] The above-mentioned hard base is usually made of glass. Although the hardness of this base meets the requirements, its surface is not flat enough and often has ups and downs. The bubbles in the space will push up some bubbles on the back of the relatively soft flexible substrate, and even cause irreversible plastic deformation of the flexible substrate, that is, the flexible display substrate will undergo irreversible plastic deformation.

The irregular unevenness of the flexible substrate substrate will lead to uneven characteristics of the device on it, thus affecting the quality of the flexible display substrate
