AI Technical Summary

Problems solved by technology

When the cutting error Δ cannot be effectively reduced, it will lead to difficulties in cutting and trimming
It is not feasible to leave too many borders due to cutting difficulties, because if you want to do display splicing, the borders will affect the splicing effect

Abstract

A display device (4), a splicing display device (5) and a display backplane (1), the display backplane (1) is provided with a plurality of pixel regions (2), each pixel region (2) comprising three different emission Light-emitting diodes (21) for color light; the display backplane (1) includes at least two backplanes, wherein the light-emitting diodes (21) emitting light of any color are arranged on one backplane; the light-emitting diodes emitting light of the other two colors (21) The remaining backplanes are arranged on the at least two backplanes; the at least two backplanes are stacked and arranged, and the other backplane located on the side where the light emitting diodes (21) are provided on one backplane is a light-transmitting plate.

Description

technical field [0001] The present invention relates to the technical field of Micro-LED displays, in particular to a display backplane, a display device and a splicing display device. Background technique [0002] As a new type of solid-state light source, LED (Light Emitting Diode, light-emitting diode) has been widely used in display devices. [0003] Micro light emitting diode (MicroLED) usually refers to reducing the size of the MicroLED chip to a size within 200 microns on the basis of the traditional MicroLED chip structure, and arranging the red, green and blue MicroLEDs in accordance with certain rules. Micro-devices capable of realizing full-color display are formed on thin film transistors (Thin Film Transistor, TFT) or complementary metal oxide semiconductors (Complementary Metal Oxide Semiconductor, COMS). This kind of display has independently controlled display pixels, independent light-emitting control, high brightness, low power consumption, ultra-high reso...
