Abstract

An embodiment of the invention discloses a Micro-LED display panel and a method for manufacture that same, the Micro-ED display panel includes: a bonding substrate; Electroluminescence Micro-LED pixelarray is inverted on one side of the bonding substrate and electrically connected with the bonding substrate, wherein, each electroluminescent Micro-LED pixel includes a first class of sub-pixel anda second class of sub-pixels; A luminescent medium lay is located on a side of that first class of sub-pixels away from the bonding substrate, and the material of the luminescent medium layer comprises an organic luminescent material. An embodiment of the invention provides a Micro-LED display panel emits light of its own color through a second class of sub-pixels, and the first class of sub-pixels emits light through an electroluminescent Micro-LED pixel excites the organic luminescent material in the luminescent medium layer to emit light corresponding to the color, so that full color display of the Micro-LED display panel is realized. A problem of difficulty in implementingcolor display of the Micro-LED display panels in the prior art is solved.

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. ...
