Display module and display device

Abstract

The invention discloses a display module and a display device. The display module comprises a display panel, a back film, a supporting structure layer, a polaroid and a cover plate, wherein the back film is attached to the surface, away from the display side, of the display panel, the supporting structure layer is arranged on the side, away from the display panel, of the back film, the polaroid is stacked on the display side of the display panel, at least one side edge of the back film covers the end surface of the corresponding side edge of the display panel and is in contact with the polaroid, the supporting structure layer comprises a metal layer and a functional layer arranged on the side, facing the back film, of the metal layer, at least one side edge of the metal layer wraps the end surface of the corresponding side edge of the functional layer and makes contact with the back film, the polaroid and the back film are arranged to be capable of conducting static electricity, and the static electricity of the edge part of the polaroid can be conducted to the metal layer through the back film. The display module disclosed by the embodiment of the invention can prevent the problem of screen greening caused by static electricity generated on the surface of the cover plate.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of display technology, and in particular to a display module and a display device. Background technique [0002] Flexible 3D oled (organic electroluminescent diode) display modules have developed rapidly in recent years, and hyperboloid mobile phones have become a hot topic for domestic mobile phone manufacturers. However, after the green screen incident in the industry, the problem of "green screen doors" has always plagued major panel manufacturers. [0003] The reason for some green screen problems is that a large amount of charge is generated after the front of the cover is rubbed (such as a copper rod friction test), and the charge is accumulated along the edge of the cover at the edge of the adhesive layer on the back of the cover. The charge accumulated at the edge of the composite layer will cause the forward-biased leakage of the driving thin film transistor (DTFT) of the display p...

Problems solved by technology

[0003] The reason for some green screen problems is that a large amount of charge is generated after the front of the cover is rubbed (such as a copper rod friction test), and the charge is accumulated along the edge of the cover at the edge of the adhesive layer on the back of the cover. The charge accumulated at the edge of the composite layer will cause the positive bias leakage of the driving thin film transistor (DTFT) of the display panel on the back of the display panel, which will cause the screen to display low grayscale brightness and green
