Classification: CPC G | IPC G

Claim 9:
10. A drive board for a display screen, comprising:
a timing controller, configured to determine, based on a source image, compensated grayscales by the method as defined in claim 1, and generate a timing control signal;
a voltage conversion circuit, configured to generate a reference voltage signal and a row drive signal based on a power supply; and
a grayscale voltage generation circuit, connected to the voltage conversion circuit, and configured to generate grayscale voltages required by grayscales of pixels of a panel based on the reference voltage signal;
wherein the timing control signal and the row drive signal are supplied to a row drive circuit of the panel, and the compensated grayscales, the timing control signal, and the grayscale voltages required by the grayscales of the pixels of the panel are supplied to a column drive circuit of the panel.
