Title:
DISPLAY DEVICE USING MICRO-LEDS AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/066221
Kind Code:
A1
Abstract:
The present specification provides a display device using semiconductor light-emitting elements mounted on an assembly substrate in fluid, and a method for manufacturing same. The assembly substrate on which semiconductor light-emitting elements are mounted (assembled) comprises first assembly electrodes and second assembly electrodes intersecting the first assembly electrodes. By a dielectrophoretic force generated by applying a voltage to the assembly electrodes, semiconductor light-emitting elements may be mounted at the intersections of the assembly electrodes. In addition, by using the assembly substrate as a repair substrate, a region of the substrate in which assembly defects have occurred can be repaired, after assembly or transfer of the semiconductor light-emitting elements.
