Problems solved by technology

However, in the cutting process, only the flexible part can be cut, and the underlying glass cannot be damaged, because once the glass is damaged, there may be a risk of cracks and fragments in the subsequent process, which will affect the overall process yield

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] In order to solve the above-mentioned problems in the prior art, an embodiment of the present invention provides a method for manufacturing a flexible display device, such as figure 1 shown, including:

[0024] Step 11, providing a rigid carrier (such as a glass carrier);

[0025] Step 12, forming a protection pattern on the rigid carrier; in this step, a material layer of the protection pattern can be deposited on the glass substrate, and a protection pattern corresponding to the cutting track is formed through a patterning process; or, the protection pattern is printed on the rigid carrier board;

[0026] Step 13, forming a flexible substrate including a reserved area and a non-reserved area on the rigid carrier on which the protective pattern...

Abstract

The invention provides a flexible display device and a manufacturing method thereof, and relates to the manufacturing field of displays. The manufacturing method includes: providing a rigid carrier board; forming a protection pattern on the rigid carrier board; covering the protection pattern; manufacturing a display device of a flexible display device on the reserved area of ​​the flexible substrate substrate; cutting the flexible substrate substrate to separate the reserved area and the non-reserved area of ​​the flexible substrate substrate; wherein, cutting The traces of the cutouts fall into the area where the protection pattern is located; peel off the cut flexible substrate substrate from the rigid carrier board. In the solution of the present invention, a protection pattern is arranged on the cutting track corresponding to the rigid carrier board, and the protection pattern is used to prevent the cutting from causing damage to the rigid carrier board, thereby preventing the rupture of the rigid carrier board from affecting subsequent production of the flexible display device.

Description

technical field [0001] The invention relates to the field of display manufacturing, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] The existing method for manufacturing flexible display devices is usually to coat a flexible substrate on a glass carrier to form a flexible substrate, and then prepare TFTs and light-emitting elements on the flexible substrate. After the production of the display device is completed, the flexible device (flexible substrate, TFT, and light-emitting element) is usually separated from the glass carrier by using a laser, but since there will be unevenness at the beginning and end of the flexible substrate coating, That is, the properties at the edge of the flexible substrate will be different from those in the central area, so in the process of laser separation, it will be difficult to separate the entire glass from the flexible device, and even cause damage to the flexible device. The s...
