Abstract

The invention relates to the technical field of mass transfer, in particular to a mass transfer method and device for a light emitting diode. The invention is used for solving problems that in the prior art, the placing direction of a light-emitting diode in a groove cannot be controlled, and in order to control the placing direction of the light-emitting diode, special-shaped design needs to be conducted on the light-emitting diode, so that the manufacturing cost is increased, and the manufacturing difficulty is increased. The method comprises the following steps: forming a hydrophobic layeron a first surface of a to-be-transferred light emitting diode; placing a transfer device at the bottom of a liquid storage container, and forming an underwater adhesive in a part of or all grooves ofthe transfer device; forming a plurality of bubbles in the first liquid; adhering the bubbles by utilizing the first surface of the light emitting diode, and enabling the second surface of the lightemitting diode adhered with the bubbles to sink downwards into part or all of the grooves; taking out the transfer device, and transferring the light emitting diode to the substrate to be transferredthrough overturning, aligning and degumming treatment.

Description

technical field [0001] The invention relates to the technical field of mass transfer, in particular to a method and device for mass transfer of light-emitting diodes. Background technique [0002] The light-emitting diode display device has the characteristics of independent control of the picture, independent light emission control, high luminance, low power consumption, ultra-high resolution and high chromaticity. It will become one of the hot spots in the development of display technology in the future. Contents of the invention [0003] The main purpose of the present invention is to provide a method and device for mass transfer of light emitting diodes. It is used to solve the problem in the related art that it is impossible to control the placement direction of the light emitting diodes in the groove, and in order to control the placement direction of the light emitting diodes, it is necessary to design the light emitting diodes with special shapes, which increases ...
