Abstract: A pixel correction circuit includes a signal input circuit, a follower and a reading circuit. The signal input circuit is used to apply a first signal and a second signal to the follower in a correction mode. An input terminal of the follower is coupled to the signal input circuit. The follower is used to receive the first signal and the second signal sequentially, output a first follow-up signal dependent on the first signal, and output a second follow-up signal dependent on the second signal. The reading circuit is coupled to an output terminal of the follower, and reads the first follow-up signal and then generates a first read signal, and reads the second follow-up signal and then generates a second read signal. The reading circuit uses the first signal, the second signal, the first read signal and the second read signal to calculate a compensation gain.
