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 fabricating method thereof and relates to the fabricating field of a display. The fabricating method comprises: providing a rigid carrier plate; forming a protective pattern on the rigid carrier plate; forming a flexible supporting base substrate, which comprises a reserved area and a non-reserved area and covers the protective pattern, on the rigid carrier plate where the protective pattern is formed; fabricating a display device of the flexible display device on the reserved area of the flexible supporting base substrate; cutting the flexible supporting base substrate to separate the reserved area of the flexible supporting base substrate from the non-reserved area; enabling a cutting trajectory to fall into an area where the protective pattern is located; and stripping the flexible supporting base substrate, after being cut, off the rigid carrier plate. According to the scheme of the invention, the protective pattern is disposed on the cutting trajectory corresponding to the rigid carrier plate, the rigid carrier plate is prevented from damage, which is caused by cutting, through the protective pattern, and then subsequent fabricating of the flexible display device is prevented from being influenced after the rigid carrier plate is cracked.

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...
