Abstract

The present application proposes a micro light-emitting diode and a manufacturing method thereof. The manufacturing method includes forming a first monomer composed of LED light-emitting units arranged at intervals on a first substrate, and a combination of an inorganic monomer and an LED light-emitting unit. Combining the monomers and transferring them from the first substrate to the second substrate through the principle that the inorganic monomers and LED light-emitting monomers have different bandgap widths to complete the transfer of the micro light-emitting diodes. The present application transfers the LED light-emitting monomers from the first substrate to the second substrate by using lasers with different wavelengths, which reduces the workload and improves the transfer dispersion rate.

Description

technical field [0001] The present application relates to the display field, in particular to a micro light emitting diode and a manufacturing method thereof. Background technique [0002] Micro light-emitting diode (Micro LED) technology refers to a micro-sized LED array integrated with high density on a substrate. As an emerging display technology, micro-light-emitting diode display has more advantages than LCD and OLED displays, such as lower power consumption, higher color gamut, faster response rate, etc., but its technical difficulty is greater than that of LCD or OLED. At present, micro-LED technology is beginning to develop, and the industry is expecting high-quality micro-LED products to enter the market. High-quality micro-LED products will have a profound impact on traditional display products such as LCD / OLED already on the market. [0003] In the process of manufacturing micro-light-emitting diodes, micro-light-emitting diodes are first formed on a donor wafer...
