Problems solved by technology

[0003] At present, UV-curable OCA optical glue is often used to adhere the display panel and the protective cover. However, in the curved display panel, since the display panel needs to fit the curved part of the protective cover, at least one side of the display panel Bending is required, and during the bending process, the traces and components of the display panel at the bending position are prone to fracture due to the influence of bending stress, thus affecting the yield of the display panel

Abstract

The invention discloses an adhesive material, a display module and a manufacturing method of the display module. The display module comprises a plane area and a bending area adjacent to the plane area; the display module further comprises a display panel, a cover plate and an adhesion layer. The cover plate is arranged on one side of the display panel; the adhesion layer is arranged between the display panel and the cover plate, and the display panel and the cover plate are attached through the adhesion layer; wherein the adhesion layer comprises a bending part located in the bending area and a plane part located in the plane area, one end of the bending part is connected to the plane part, the other end of the bending part extends in a bent shape, and the thickness of the bending part is smaller than that of the plane part. According to the display module, the curvature radius of the display panel when the display panel is bent in the bending area can be reduced, the bending stress borne by the display panel is reduced, the probability that the display panel is damaged due to the bending stress is effectively reduced, and the yield of the display module is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an adhesive material, a display module and a manufacturing method thereof. Background technique [0002] As customers have higher requirements for the display and touch of smart devices, many well-known manufacturers have tried to adopt the full bonding technology of touch display modules, that is, the Cover Lens (protective cover) and the display panel are bonded with OCA optical glue. Compared with the traditional lamination method, the full lamination technology is thinner and has better light transmission. In addition to providing better display effects, the strength of the protective cover is also improved due to the tight combination with the display panel, and there is no need to consider Dust-proof and waterproof, so the position of the frame of the display module does not need to consider the fit width, which can make the frame of the display module narrower.
