Abstract

The invention discloses an LED array and a preparation method thereof. The LED array includes a supporting substrate; a plurality of LED structures arranged in preset positions on the surface of the supporting substrate, wherein each LED structure sequentially comprises a metal reflecting layer, a P electrode, an epitaxial layer and an N electrode; MOS transistors arranged in one-to-one correspondence with the LED structures on the surface of the supporting substrate, the LED structures being connected in series with the MOS transistors through the metal reflecting layers and / or P electrodes,and on-off of each LED structure being controlled through the MOS transistor connected therewith. The LED structures and MOS transistors are arranged on the surface of the supporting substrate in one-to-one correspondence, and are connected in series, one-to-one control is realized, and in the LED array, the LED structures can work independently simply and conveniently, and the normal work of other LED structures in the array is not affected.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an LED array 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 object of the present invention is to provide an LED array 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] An LED array comprising: [0006] supporting substrate; [0007] A plurality of LED structures arranged at preset positions on the surfac...
