Abstract

The invention discloses an LED array structure and a preparation method thereof, the structure comprising: a plurality of LED structures, wherein the LED structures sequentially comprise a metal reflecting layer, a P-type ohmic contact layer, an epitaxial layer and a transparent N electrode; MOS transistors arranged in one-to-one correspondence with the LED structures, the LED structures being bonded or adhered to the surfaces of the MOS transistors through the metal reflecting layer, and on-off of each LED structure being controlled through the MOS transistor connected therewith; and a commontransparent conductive layer provided on the N electrode surfaces of the plurality of LED structures. The MOS transistors which control the on-off of the LED structures are connected through bondingor bonding, so as to realize one-to-one control. In the LED array structure, the independent work of the LED structures is realized simply and conveniently, and the normal work of other LED structuresin the array structure is not affected.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an LED array structure and a preparation method thereof. Background technique [0002] As a new generation of display technology, Mini LED and micro LED are derived from the miniaturization of the LED structure, inheriting the characteristics of the LED, with low power consumption, high brightness, ultra-high resolution and color saturation, fast response, ultra-saving However, there is no good solution for the independent control of mini LED and micro LED on-off. Contents of the invention [0003] The purpose of the present invention is to provide an LED array structure and a preparation method thereof, which realize independent control of on-off of mini LED and micro LED. [0004] The technical scheme provided by the invention is as follows: [0005] A LED array structure, comprising: [0006] A plurality of LED structures, which sequentially include a metal reflect...
