Abstract

A micro-LED panel, an operating method thereof, and a pixel compensation circuit are provided. The pixel compensation circuit includes: a main LED; a backup LED; a first transistor coupled to the main LED and receiving an emission control signal; a second transistor coupled to the backup LED; and a first capacitor coupled to the second transistor and receiving the emission control signal. When the main LED fails, the first capacitor is fused and damaged to be short-circuited, and the second transistor drives the backup LED to emit light.
