Description

Light-emitting substrate and display device

Technical Field

The present utility model relates to the field of display technologies, and in particular, to a light emitting substrate and a display device.

Background

Compared with the conventional LCD (Liquid Crystal Display, LCD) display technology with light emitting diode (Light Emitting Diode, LED) backlight, the LCD display technology adopting Mini LED backlight technology has better performance in dynamic contrast, brightness, color gamut and visual angle, and has the advantages of light weight, high image quality, low power consumption, energy conservation and the like.

The Mini LED is a direct type display backlight source, has the advantages of high resolution, high brightness and the like, can realize product differentiation, can achieve the display effect from the aspects of image quality, saturation and contrast, and has competitive cost. The Mini LED potential application market comprises an electronic competition screen, a commercial display market, a watch, a vehicle-mounted display, an AR/VR, a projection, a TV market and the like, and the Mini LED display gradually develops to smaller intervals because the small-interval Mini LED screen has the advantages of no visual joint, clearer image quality and the like.

At present, when the Mini LED lamp panel is installed, screws or double faced adhesive tape are usually used for fixing. Because the size is smaller, the screw fixing mode is more troublesome to disassemble and assemble by using the screw, and the lamp panel is easy to damage. The disadvantage of using double-sided adhesive tape for fixation is that the pasting is very troublesome, the positioning is difficult, and the lamp panel is easy to damage. Therefore, the existing mounting method of the lamp panel is low in assembly efficiency and difficult to position.
