Abstract

The invention provides a preparation method for a flexible display. The preparation method comprises the steps of providing a carrier; forming a sacrificial layer on the carrier; forming a first packaging barrier layer, a display assembly, a second packaging barrier layer and a flexible substrate on the sacrificial layer in sequence; and stripping the carrier from the sacrificial layer, wherein the first packaging barrier layer, the display assembly, the second packaging barrier layer and the flexible substrate form the flexible display. According to the flexible display formed in the invention, the flexible substrate is used as the carrier of the flexible display, and is positioned on the second packaging layer, so that the flexible substrate does not suffer from influence from a high-temperature process in the preparation of the display assembly; and material selection of the flexible substrate is higher in degree of freedom, so that the prepared flexible display can ensure flexibility of the flexible substrate as well as can ensure the water oxygen blocking capability of the first packaging barrier layer, thereby improving the performance of the flexible display.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a method for preparing a flexible display. Background technique [0002] Organic Light Emitting Display (OLED, Organic Light Emitting Display) is an active light-emitting device. Compared with the current mainstream flat-panel display technology Thin Film Transistor-Liquid Crystal Display (TFT-LCD, Thin FilmTransistor-Liquid Crystal Display), OLED has high contrast and wide viewing angle. , low power consumption, thinner volume and other advantages, it is expected to become the next generation of flat panel display technology after LCD, among which flexible OLED is more and more popular in flat panel display technology because of its advantages of bendability, impact resistance, lighter and thinner. more and more attention. The base materials for flexible displays are usually thin metals, soft glass and plastic films. Among them, soft glass and plastic film are the resea...
