Problems solved by technology

[0004] In order to improve this problem, the usual method is to increase the viscosity of the adhesive layer, but the increase in viscosity will decrease the cohesion, which means that the holding force of the colloid will decrease. Under the action of the COF resilience, the colloid itself will pull the glue, and the COF will warp and integrate. machine interference, the risk of bright lines increases, and if it happens at the user end, it will cause incalculable losses

Abstract

The present application provides a display module and a display device, so as to avoid warping of the chip on film after bending, reduce the risk of displaying bright lines, and improve the yield of the display module. The display module display module comprises: a display panel with oppositely arranged light emitting surface and backlight surface; an intermediate film layer covering the backlight surface of the display panel; a fixed connection structure fixed on the side of the intermediate film layer away from the display panel , and one end of the fixed connection structure protrudes from the side of the display panel; one end is connected to the light-emitting surface of the display panel, and the other end is bent to the backlight surface of the display panel. The outer periphery of one end of the side surface of the panel is bent to the backlight surface of the display panel, and the fixed connection structure is used to fix the bent shape of the chip on film and the part of the chip on film that is bent to the backlight surface of the display panel. The display device includes the display module.

Description

Technical field [0001] This application involves the field of display technology, especially a display module and display device. Background technique [0002] At present, the flexible mobile phone module mostly uses Pad Bending (terminal bending) and COF BeENDING solution. In order to ensure the height after Pad Bending or Cof Bending, and protect the IC (the full English English of IC is: Integrated Circuit Corresponding Chinese are: integrated circuits), it is necessary to use the rubber layer to stick to the PAD or COF firmly. Usually COF is hard, and the elasticity is large after bending. At the same time, the COF material is PI (the full English English of PI is: Polyimide, the corresponding Chinese is: polyimide), which can be low on the surface, so that the COF bonding is not solid. Lift up and reduce the module yield. [0003] like figure 1 and figure 2 It shows that the display module 1 'in the existing technology includes the display panel 10', the intermediate membran...
