Abstract

The invention discloses a light-emitting substrate, a display module and a display device, and belongs to the technical field of display. The light-emitting substrate comprises a substrate, a drivingcircuit layer, a light-emitting structure layer and a first reflecting layer; the driving circuit layer comprises a first voltage signal line and a second voltage signal line, and the first reflectinglayer comprises a plurality of first reflecting parts. The display module comprises a display panel and a backlight assembly which are oppositely arranged, the backlight assembly comprises the light-emitting substrate and a plurality of touch electrodes arranged in an array mode, a gap is formed between every two adjacent touch electrodes, and the first reflection part at least partially covers the gaps. The display device comprises the display module. The light-emitting efficiency of the light-emitting substrate can be improved, when the touch function is achieved, a metal layer does not need to be additionally arranged to manufacture the touch wire, thinning development of a module is facilitated, meanwhile, the width of the touch wire can be increased as much as possible, then the impedance of the touch wire can be effectively reduced, and the touch precision can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a light-emitting substrate, a display module and a display device. Background technique [0002] At present, the penetration rate of LED as a backlight in the field of liquid crystal panel display has exceeded 90%. The backlight module structure mainly has two types: side-in type and direct-down type. The side-in type LED backlight is to install the LED light source on the side of the light guide plate. The disadvantage of exporting light is that the contrast of the formed picture is relatively poor, and local dimming cannot be performed. The direct-lit LED backlight has gradually become the mainstream trend in the market because it presents images more accurately and exhibits excellent color and light-dark contrast effects. However, the brightness of some backlight sources in the prior art is generally low due to power limitation, which easily affects the dis...
