Document Type and Number:
WIPO Patent Application WO/2022/073397
Kind Code:
A1
Abstract:
The present application relates to the technical field of display, and provides an electronic device, and a display module and a repair method therefor. The repair method comprises: providing a driving substrate provided with a plurality of pixel units, each of the pixel units comprising three first micro light-emitting diodes and a micro light-emitting diode chip; and if a first micro light-emitting diode in the pixel unit cannot work normally, performing color resist packaging on the first micro light-emitting diode chip to replace a light-emitting function of the first microlight-emitting diode which cannot work normally in the pixel unit. According to the method provided by the present application, a micro light-emitting diode chip is used as a standby in an existing pixel structure to achieve an effect of replacing a first microlight-emitting diode which cannot work normally, thus finally achieving low-cost and high-efficiency mass repair of a display module.
