Abstract

The present invention relates to a display device comprising: a display panel having a plurality of pixels and a plurality of source lines, wherein each of the pixels is electrically connected to a respective source line; and an SD IC for providing pixel voltages and receiving a noise storage control signal and a noise output control signal; characterized in that the SD IC further comprises a noise reduce module to store voltage levels of the pixel voltages as compensating voltages based on the noise storage control signal and to output the compensating voltages based on the noise output control signal, wherein during a normal period, the SD IC outputs the pixel voltages to the pixels; during a compensation period, the SD IC outputs the compensating voltages to the pixels; wherein the noise output control signal is phased-delayed with respect to the noise storage control signal.
