Abstract

The invention discloses a display module and a display device. The display module includes: a display panel, a backlight module, and an adhesive tape for fixing the display panel and the backlight module; wherein, the adhesive tape has a first bending axis and a second bending axis extending in a first direction and parallel to each other. A bending axis and a second bending axis divide the adhesive tape into the first part, the second part and the third part which are sequentially connected; when the adhesive tape is unfolded into a flat state, the adhesive tape includes multiple auxiliary functions which are superimposed on each other in the third direction Layers, at least one auxiliary function layer includes a plurality of auxiliary units extending along a first direction and arranged sequentially along a second direction, and the third direction is respectively perpendicular to the first direction and the second direction. The display module and the display device provided by the present invention reduce the risk of the adhesive tape lifting from the surface of the display panel, thereby reducing the risk of poor display of the display module, and improving the performance reliability of the display module and the display device.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and more particularly, to a display module and a display device. Background technique [0002] In the production of the existing display module, the display panel and the backlight module need to be fixed by adhesive tape. figure 1 A cross-sectional schematic diagram of a display module in the prior art, such as figure 1 As shown, the display panel 11 and the backlight module are arranged oppositely. The backlight module includes: an optical film set 121, a light guide plate 122, a reflector 123, a light source 124, a plastic frame 125 and a back plate 126. The adhesive tape 13 is attached to the display edge of the panel 11, and wrap the top of the plastic frame 125 and the outer surfaces of the side panels and the bottom panel of the back panel 126 to realize the fixing of the display panel 11 and the backlight module 12. However, in the prior art, when the adhesive tape 13 wra...
