Claim 5:
6. An operation method of a display control device, comprising:
performing arithmetic operation, by a data analyzing circuit of the display control device, on a plurality of sub-pixel data output by a target driving channel of a source driver in an active data period of a current frame period to obtain a resultant value corresponding to the target driving channel;
determining, by a data compensation circuit of the display control device, at least one compensation grayscale value corresponding to the resultant value;
detecting a frame rate by a frame rate detection circuit of the display control device; and
determining the at least one compensation grayscale value as a single compensation grayscale value or a plurality of compensation grayscale values according to the frame rate,
wherein the at least one compensation grayscale value is to be displayed by the target driving channel in a vertical blank period of a frame period in which the current frame is displayed, and
wherein the target driving channel of the source driver outputs at least one compensation voltage corresponding to the at least one compensation grayscale value in the vertical blank period of the frame period.
