Abstract

The invention provides a repairing device of a display panel, and the device comprises a defect sensor which is used for carrying out the defect inspection of the display panel, and obtaining defect information; a chip picking and placing part which is used for picking up, storing and releasing the light-emitting chips, wherein the chip taking and placing part comprises a chip accommodating cavityand a controller, the chip accommodating cavity is used for storing the light-emitting chips, and the controller is used for picking up and releasing the chips; a chip moving part which is connectedwith the chip taking and placing part and is used for moving the chip taking and placing part to the position of the defect according to the defect information; and a chip binding part which is used for binding the light-emitting chip on the display panel.

Description

technical field [0001] The present application relates to the display field, in particular to a repairing device for a display panel. Background technique [0002] Micro-light emitting diodes (Micro-light emitting diodes, MicroLED) have the advantages of high brightness, good luminous efficiency, low power consumption, long life and thinness. It is expected to become the mainstream display technology of the next generation. [0003] The manufacturing method of Micro LED is mainly to arrange arrays of LEDs of several microns to tens of microns after miniaturization on the substrate to form an LED array with high density and small size. However, the lighting yield of Micro LED display devices manufactured by mass transfer still cannot meet the technical requirements of 99.9999% in the mass production stage. Therefore, the display panel needs to be repaired after the transfer process is completed. In the repair process, different process fixtures need to be prepared for subs...
