Manufacturing method of flexible display devices

Abstract

The invention provides a manufacturing method of flexible display devices. The manufacturing method comprises the following steps of: forming a releasing layer on a transparent hard substrate, wherein the releasing layer is made of an ultraviolet light resolving material added with inert matters; combining a flexible substrate to the transparent hard substrate formed with the releasing layer, wherein the flexible substrate is opposite to one side, at which the releasing layer is formed, of the transparent hard substrate; forming a display component on the flexible substrate; irradiating from one side, far away from the releasing layer, of the transparent hard substrate with the ultraviolet ray so as to trigger the releasing layer to have a photochemical reaction which emits gas, so that the transparent hard substrate is isolated from the flexible substrate. According to the manufacturing method, the production process of the flexible display device can be simplified.

Description

technical field [0001] The invention relates to a method for preparing a flexible display device, in particular to a method for attaching and separating a flexible display device based on the ultraviolet light decomposition material and ultraviolet reaction characteristics. Background technique [0002] Liquid crystal display (LCD) technology has developed rapidly in the past ten years, and great progress has been made in terms of screen size and display quality. After continuous efforts, the performance of LCD in all aspects has reached the level of traditional cathode ray tube display (CRT), and it has a tendency to replace CRT. [0003] With the continuous expansion of LCD production, the competition among various manufacturers is becoming increasingly fierce. While manufacturers are constantly striving to reduce the production cost of products, they are also constantly improving product performance and adding more functions, thereby increasing the added value of product...

Problems solved by technology

[0005] The current method of sticking and removing is to use an adhesive to stick the organic plastic substrate on the glass substrate. After the display device is prepared, a high-energy laser beam is used to scan the back of the display to make the adhesive aging. Decreased adhesion performance, allowing organic plastic substrates to be peeled off from glass substrates

However, due to the need for high-energy laser beam scanning, this method has low production efficiency and poor peeling uniformity.
