Classification: CPC G | IPC G

Claim 13:
14. The display driving device of claim 12, wherein the display control device further comprises:
a frame rate detection circuit, coupled to the data compensation circuit, configured to detect the frame rate;
wherein the data compensation circuit determines the at least one compensation grayscale value as the single compensation grayscale value or the plurality of compensation grayscale values according to the frame rate;
when the data compensation circuit outputs the single compensation grayscale value to the source driver during the vertical blank period of the frame period, the target driving channel of the source driver outputs a grayscale voltage corresponding to the single compensation grayscale value during the vertical blank period of the frame period; and
when the data compensation circuit outputs the plurality of compensation grayscale values to the source driver during the vertical blank period of the frame period, the target driving channel of the source driver outputs a plurality of compensation grayscale voltages corresponding to the plurality of compensation grayscale values at different line periods in the vertical blank period of the frame period.
