Abstract: A display driver and a polarity inversion method thereof are provided. The display driver includes multiple channel pairs and a polarity inversion control circuit. The channel pairs are suitable for driving a display panel. Each of the channel pairs includes a positive polarity channel, a negative polarity channel, and a switching circuit.

Abstract: A control method, suitable for a display panel including M scan lines and a plurality of source lines, include following operations. M is a positive integer. M gate signals are generated sequentially in M time periods during a first display frame to the M scan lines of the display panel.

N gate signals are generated in N time periods selected from the M time periods during a second display frame to N scan lines selected from the M scan lines. (M-N) gate signals are suspended during the second display frame. The level of the data signal is updated in the N time periods and is not updated in the (M-N) time periods during the second display frame. N is a positive integer smaller than M.
