Embodiment Construction

[0024] As mentioned in the background art, in the prior art, the lifespan of the roll-up flexible display device decreases with the increase of the number of rolls, thus making the roll-up flexible display device have a low lifespan. The inventors have found that the reason for this problem The non-display area at one end of the flexible display body in the roll-up flexible display device is bonded and fixed on the roll shaft, but due to the small non-display area of ​​the flexible display screen, the bonding between the flexible display body and the roll shaft The fixed area is small, and when the flexible display screen is pulled for many times, the flexible display screen body is easy to loosen from the curling shaft, thereby reducing the service life of the roll-up flexible display device.

[0025] Based on this, the present invention provides a roll-up flexible display device. By making the length of the polarizer in the flexible display body longer than the length of the ...

Abstract

The invention provides a crimped flexible display device, and solves the technical problem of short service life of a crimped flexible display device in the prior art. According to the crimped flexible display device, the length of a polarizer in a flexible display screen body is enabled to be larger than the length of a substrate, so that the part, longer than the flexible display substrate, in the polarizer can be bonded and fixed on a crimping device; compared with the prior art that a non-display region (the area of the non-display region is small) of the flexible display screen body is fixed in the crimping device, the bonding area of the flexible display screen body and the crimping device is enlarged, and after being pulled for multiple times, the flexible display screen body is still bonded and fixed on the crimping device, so that the service life of the crimped flexible display device is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a rollable flexible display device. Background technique [0002] With the expansion of the application field of flexible display screens, flexible screen curling terminals have gradually entered the public's field of vision, and flexible screen curling can meet the needs of users in pursuit of large screens, large vision and portability to a greater extent. However, the lifespan of the rollable flexible display will decrease as the number of rolls increases, so that the lifespan of the rollable flexible display is short. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a rollable flexible display device, which solves the technical problem of short life of the rollable flexible display device in the prior art. [0004] In order to make the purpose, technical means and advantages of the present invention clearer, the present i...
