Claim 10:
11. A display driving device, comprising:
a source driver; and
a display control device, coupled to the source driver, configured to control a driving operation of the source driver to drive a display panel, wherein the display control device performs arithmetic operation on a plurality of sub-pixel data output 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, the display control device determines at least one compensation grayscale value corresponding to the resultant value, the display control device detects a frame rate and 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, 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.
