Description:

Horizontal lines were discovered during the reliability test of micro-LED display. The basic reason is the short of metal lines with different voltages owing to edge design and film structure. By optimizing process flow and backplane design, the defect is significantly improved. Furthermore, several suggestions of design have been proposed.
