Problems solved by technology

[0004] Now, after the product is designed in the bending process, if the quality of the bending area is not up to standard, it needs to be disassembled. Because the adhesive tape of the bending reinforcement board is strong, it will cause serious damage to the metal circuit after dismantling, making it impossible to rework the product and reducing the product quality. Utilization

Embodiment Construction

[0029] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0030] The present invention is aimed at the design of existing products. After the bending process, if the quality of the bending area is not up to standard, it needs to be disassembled. Because the adhesive tape of the bending reinforcement board has strong viscosity, it will cause serious damage to the metal circuit after disassembly. This embodiment can solve this ...

Abstract

The invention provides a reinforcing plate adhesive layer structure, a screen bending area structure and a display screen. The reinforcing plate adhesive layer is a three-layer structure, the upper layer is a first viscous adhesive layer, the middle layer is a hard plate layer, and the lower layer is a second viscous adhesive layer. The first and second viscous adhesive layers are segmented structures, both ends of the first viscous adhesive layer and the second viscous adhesive layer adopt a strong viscous material, and the middle parts adopt a weak viscous material. The reinforcing plate adhesive layer can be easily dismantled during disassembly, the risk of newly increased fracture of lines can be avoided, and the product repair yield is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a structure of a glue layer of a reinforcing plate, a structure of a bending area of ​​a screen, and a display screen. Background technique [0002] At present, the smart consumer electronics industry is in a stage of rapid development. Consumers are increasingly favoring electronic products with high technical content, and their requirements for innovation in electronic products are getting higher and higher. In recent years, the concept of folding screen mobile phones has become popular, and has gradually been valued by major manufacturers, becoming the direction of future smartphone development. [0003] In the modern communication industry, the market demand for mobile phones, TVs, tablets, notebooks, digital cameras and other products is increasing, and various display devices are also developing towards being bendable. In the manufacture of flexible full-screen display mod...
