Claim 0:
1. A display control device for controlling a driving operation of a source driver to drive a display panel, comprising:
a data analyzing circuit, configured to perform arithmetic operation on a plurality of sub-pixel data outputted by a target driving channel of the source driver in an active data period of a current frame period to obtain a resultant value corresponding to the target driving channel;
a data compensation circuit, coupled to the data analyzing circuit for receiving the resultant value, and configured to determine at least one compensation grayscale value corresponding to the resultant value, 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 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; and
a frame rate detection circuit, coupled to the data compensation circuit, configured to detect a frame rate,
wherein the data compensation circuit determines 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.
