Problems solved by technology

[0003] Each sub-pixel in a Micro-LED display is provided with a Micro-LED grain, and each Micro-LED grain is individually addressed and emits light independently. Since the distance between two adjacent Micro-LED grains is extremely small, and There are hundreds of thousands of Micro-LED grains in a Micro-LED display, so at present, the difficulty in the manufacturing process of Micro-LED displays is to transfer a huge amount of Micro-LED grains from the donor substrate to the circuit substrate

Abstract

The embodiment of the invention provides a transfer device, Micro-LED grains and a transfer method and relates to the field of display technology. The transfer device and the transfer method are usedfor transferring a huge quantity of the Micro-LED grains. The transfer device comprises a bearing plate, a first controller and multiple transfer heads arranged on the first surface of the bearing plate; each transfer head comprises a solenoid, wherein the two ends of the solenoid are electrically connected with the first controller through a wire, and the solenoid is used for generating a magnetic field when powered on; and the first controller is electrically connected with the solenoid in each transfer head and used for controlling the solenoid in each transfer head to be powered on or off.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transfer device, Micro-LED crystal grains and a transfer method. Background technique [0002] Micro-LED Display (miniature light-emitting diode display) has the advantages of ultra-high pixels, ultra-high resolution, high brightness, low power consumption, stable material performance, long life, and no image burn-in, and its performance is much higher than that of existing LCD (Liquid Crystal Display, Liquid Crystal Display) and OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode), therefore, are widely used in fields such as micro-projection, transparent display, and head-up display. [0003] Each sub-pixel in a Micro-LED display is provided with a Micro-LED grain, and each Micro-LED grain is individually addressed and emits light independently. Since the distance between two adjacent Micro-LED grains is extremely small, and There are hundreds of thousands of M...
