Abstract

The invention provides a Micro-LED display substrate, a making method thereof and a display device, and belongs to the technical field of display. The Micro-LED display substrate comprises a circuit substrate, blue light LED arrays, barricades and quantum dot light conversion membranes, wherein the blue light LED arrays are located on the circuit substrate; the barricades are located between adjacent LEDs and define multiple containing parts, and the containing parts correspond to the LEDs one by one; the quantum dot light conversion membranes capable of emitting multiple colors are located inthe containing parts, and the colors can be mixed to form white light. In the technical scheme, a making technology of the Micro-LED display substrate can be simplified, uniformity of light emittingintensity of sub pixels with different colors can be guaranteed, and the service life of the Micro-LED display substrate can be prolonged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a Micro-LED display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Micro (micro)-LED (light-emitting diode) is a display technology that miniaturizes and matrixes the traditional LED structure, and uses integrated circuit technology to make a driving circuit to realize the addressing control and individual driving of each pixel. Since the brightness, life, contrast, response time, energy consumption, viewing angle and resolution of Micro-LED technology are stronger than those of LCD (liquid crystal display) and OLED (organic electroluminescent diode) technologies, plus its With the advantages of self-illumination, simple structure, small size and energy saving, it is regarded as the next-generation display technology, and various leading display technology companies have begun to actively deploy it. [0003] In the prior a...
