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 here 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, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] Since the flexible display device has variable and bendable performance, the flexible display device can be bent, and a bending protection layer is provided in the bending area of ​​the flexible display device to protect the bending area of ​​the flexible display device during the bending process. parts for protection. However, before the display device is bent, the bending protection layer is coated, and there will be a certain tensile strain in the bending protection layer after bending. However, when th...

Abstract

The embodiment of the invention provides a flexible display device and a preparation method of the flexible display device. A flexible substrate of the flexible display device is provided with a firststraight area, a bent area and a second straight area; before bending, a first bending protecting layer is arranged in a bending area of the flexible substrate, so that the bending difficulty can bereduced, and the bending stress can be reduced; after bending, a second bending protecting layer is arranged in the bending area of the flexible substrate, so that creep occurring after the first bending protecting layer is bent can be prevented, meanwhile, a protection role can be further played on the bending area, so that the phenomenon that cracks occur on the flexible substrate and wires on the flexible substrate due to the fact that the protection capacity of a first bending protecting agent for the flexible substrate and a wiring layer arranged on the flexible substrate is reduced is avoided, and further, the display effect of the flexible display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a preparation method thereof. Background technique [0002] The variable and bendable properties of flexible display devices enable them to be widely used. The current production of flexible display devices is mainly to use the carrier substrate as a carrier to carry the flexible substrate, and form a display device on the flexible substrate; then separate the flexible substrate and the carrier substrate to obtain the display panel of the flexible display device; then display Panels are bound together 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 texts, etc., 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 ...
