Problems solved by technology

[0003] Although BM can reduce the reflection coefficient of the panel, the light emitted inside the panel is also blocked and unable to exit, which leads to the deterioration of the viewing angle of the panel; The reflectivity of the screen is also correspondingly increased, which is not conducive to the realization of the integrated black effect of the display screen

Abstract

The invention provides a display module and a display device. The display module comprises a display panel and a light adjusting layer located on one side of the light emitting direction of the display panel. The display panel comprises a plurality of sub-pixels, an opening is formed in the position, corresponding to any sub-pixel, of the light adjusting layer, and the openings are filled with color resistors. The light adjusting layer comprises a reflecting layer and a light shielding layer located on the side, away from the display panel, of the reflecting layer. The openings comprise first openings located in the reflecting layer and second openings located in the light shielding layer, the cross section areas of the first openings are gradually decreased in the light emitting direction, and incident light is reflected through the reflecting layer. The maximum visual angle of the display module is enlarged, the problem that the visual angle of the display module is poor is solved, and the light emitting efficiency is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] Polarizer (POL, Polarizer) can effectively reduce the reflectivity of the panel under strong light, but loses nearly 58% of the light output; on the other hand, the thickness of the polarizer is large and the material is brittle, which is not conducive to the development of dynamic bending products. The purpose of using color filter (CF, color filter) and black matrix (BM, black matrix) instead of polarizer to achieve light output and reduce screen reflectivity is called POL-less (depolarizer) technology. [0003] Although BM can reduce the reflection coefficient of the panel, the light emitted inside the panel is also blocked and unable to exit, which leads to the deterioration of the viewing angle of the panel; The reflectivity of the screen is also correspondingly increased, which is not conducive...
