Abstract

The invention provides a Micro-LED array based on micro-patterned graphene, a preparation method thereof, and a display device. The array includes: a substrate; a patterned graphene layer, the array of which is distributed on one side of the substrate; an electron injection layer located at The substrate is close to the side of the patterned graphene layer, and the electron injection layer is projected on the substrate between adjacent patterned graphene layers; the multi-quantum well layer is located on the side of the electron injection layer away from the substrate; the hole injection layer, The n-type contact electrode is located on the side of the patterned graphene layer away from the substrate; the p-type contact electrode is located on the side of the hole injection layer away from the substrate. In the Micro-LED array of the present invention, the good conductivity of graphene can also be directly used as the bottom electrode of the Micro-LED, and the contact between the patterned graphene layer and the electron injection layer forms a good conductive path, so that electrons can pass through the patterned graphene layer. Efficient injection into Micro‑LEDs.

Description

technical field [0001] The invention relates to the technical field of preparation of LEDs, in particular to a Micro-LED array based on micro-patterned graphene, a preparation method thereof, and a display device. Background technique [0002] Group III nitride materials mainly include InN, GaN and AlN, which can be mixed in any proportion to form ternary and quaternary alloys, and their direct band gaps are adjustable at 0.7-6.2 eV. Based on this, group III nitride materials as the light-emitting layer of LEDs can realize broadband light emission from deep ultraviolet to visible red light, and the corresponding Micro-LED can meet the application requirements of full-color display. Compared with the more mature OLEDs technical solutions on the market, they have the advantages of high luminous brightness, low energy consumption and long service life, and have high application potential in TV, smart phones, car navigation, AR / VR and other fields. [0003] At present, the main...
