Abstract

An embodiment of the invention discloses a Micro-LED display panel and a manufacturing method thereof, that display panel comprise: a bonding substrate; A first color pixel, a second color pixel and athird color pixel inverted on one side of the bonding substrate and electrically connected with the bonding substrate; Wherein the first color pixel comprises a first light emitting medium layer, thesecond color pixel comprises a second light emitting medium layer, and the third color pixel comprises a third light emitting medium layer; The first luminescent medium layer and the second luminescent medium layer are respectively quantum dot electroluminescent materials, and the third luminescent medium layer is a gallium nitride quantum well layer. According to the invention, a first color pixel and a second color pixel in the LED display panel emit light of the first color and light of the second color respectively through the quantum dot electroluminescent material, The third color pixelemits the light of the third color through the GaN quantum well layer, so that the Micro-crystalline GaN quantum well layer emits the light through the quantum dot electroluminescent material. Full color display of the Micro-LED display panel is achieved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a Micro-LED display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, the traditional liquid crystal display (Liquid Crystal Display, LCD) technology is gradually unable to meet the needs of the market in terms of color rendering, luminous efficiency, flexibility and portability. The new generation of lighting and display technology has become an investment and research hotspot. A new generation of lighting and display devices includes light emitting diode (Light Emitting Diode, LED) displays, wherein the light emitting diodes include organic light emitting diodes, quantum dot light emitting diodes, micro light emitting diodes and Micro-LEDs. Among them, the pixel size of Micro-LED is smaller than that of micro-light-emitting diodes, which is suitable for indoor screens and small-sized displays. ...
