Abstract

The invention discloses a pixel structure of an LED back plate, an LED display panel and a manufacturing method of the LED display panel. The pixel structure comprises a plurality of sub-pixel structures, wherein the sub-pixel structures are arranged according to an array structure, the pixel structure of the LED back plate at least comprises N rows and M columns of sub-pixel structures, each sub-pixel structure comprises a scanning line, a data line, a first power supply end, a second power supply end, an IC driving chip and a light emitting element, and in each sub-pixel structure, the light-emitting element is driven and controlled by the IC driving chip.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to a pixel structure of an LED backplane, an LED display panel and a manufacturing method thereof. Background technique [0002] Micro light emitting diode (Micro light emitting diode, referred to as Micro-LED) usually refers to reducing the size of the LED chip to a size within 200 microns on the basis of the traditional LED chip structure, and the red, green, and blue three-color Micro LED according to a certain Regularly arranged on thin film transistors (Thin Film Transistor, TFT for short) or complementary metal oxide semiconductors (Complementary Metal Oxide Semiconductor, COMS for short), form a micro-device capable of realizing full-color display. This kind of display has independently controlled display pixels, and has the characteristics of independent light-emitting control, high brightness, low power consumption, ultra-high resolution and ultra-high color satu...
