Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0032] Since the flexible display device has variable and bendable properties, the flexible display device can be bent, and a bending protection layer is arranged in the bending area of ​​the flexible display device, so that during the bending process, the bending area of ​​the flexible display device can be bent. parts are protected. However, the bending protection layer is coated before the display device is bent, and there will be a certain tensile strain in the bending protection layer after bending. However, when the bending...

Abstract

Embodiments of the present invention provide a flexible display device and a manufacturing method thereof. The flexible substrate of the flexible display device has a first straight region, a bending region and a second straight region; The first bending protective layer is set in the bending area to reduce the bending difficulty and the bending stress; the second bending protective layer is set in the bending area of ​​the flexible substrate after bending, which can prevent the first bending protective layer from bending Creep that occurs after bending, and can further provide protection for the bending area, thereby preventing the flexible substrate and the wiring layer on the flexible substrate from being reduced due to the first bending protectant. The wiring provided on the flexible substrate cracks, thereby improving the display effect of the flexible display device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a flexible display device and a preparation method thereof. Background technique [0002] The variable bendability of flexible display devices makes them widely used. The current production of flexible display devices mainly uses a carrier substrate as a carrier to carry a flexible substrate, and a display device is formed on the flexible substrate; then the flexible substrate and the carrier substrate are separated to obtain a display panel of the flexible display device; Panels are bonded with flexible circuit boards and / or chips, etc. [0003] The display panel of the flexible display device includes a display area and a non-display area. The display area is used to display images and characters, and the non-display area is provided with wiring, bound flexible circuit boards and / or chips, and the like. In order to realize the narrow frame of the flexible displa...
