Document Type and Number:
WIPO Patent Application WO/2021/132842
Kind Code:
A1
Abstract:
The present application relates to an LED display device and, more particularly, to an LED display device including a repair structure for defective pixels. The present invention is intended to stack and position a sub-micro-LED on a micro-LED in which a defect has occurred, wherein the sub-micro-LED is electrically connected to first and second connection electrodes for applying voltage to the micro-LED. Accordingly, it is possible to prevent image quality degradation from occurring due to defective pixels, and since it is not necessary to separately remove the micro-LEDs in which defects have occurred, it is possible to reduce process costs and improve process efficiency.
