Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0058] In addition, if there are descriptions involving "first", "second" and so...

Abstract

The invention discloses a manufacturing method of a flexible display and the flexible display. The manufacturing method of the flexible display comprises the steps that a release layer is formed in the middle area of a hard substrate, a flexible substrate is formed on the release layer and the hard substrate, and in the process of stripping the flexible substrate and the hard substrate, laser is utilized to irradiate a non-display area so that the non-display area can be stripped from an edge area, and then, a display area is stripped from the middle area of the hard substrate by using mechanical force. According to the technical scheme, the non-display area of the flexible substrate is irradiated by laser to separate the flexible substrate from the hard substrate, and due to the existence of the release layer, the display area of the flexible substrate can be separated from the hard substrate by using mechanical force, so that the display area of the flexible substrate is prevented from being damaged, and the yield of the manufactured flexible display is improved.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a method for manufacturing a flexible display and the flexible display. Background technique [0002] In recent years, flexible display (Flexible Display) and foldable display (Foldable Display) technologies have developed rapidly. , the forms of flexible displays are becoming more and more abundant, and while the screen size is constantly increasing, the display quality is also constantly improving. [0003] The flexible display includes a flexible substrate, a thin film transistor (Thin Film Transistor, TFT for short) array, a display device, and an encapsulation layer. Flexibility. Compared with ordinary displays, flexible displays have many advantages, such as light weight, small size, thinner, easy to carry, high and low temperature resistance, impact resistance, strong shock resistance, and rollability. [0004] At present, flexible display displays are mainly pre...
