The disclosure provides a display driving device and a display control device and an operation method thereof. The display control device includes a data analyzing circuit and a data compensation circuit. The data analyzing circuit performs arithmetic operation on multiple sub-pixel data output by a target driving channel of a source driver in a current frame to obtain a resultant value corresponding to the target driving channel. The data compensation circuit determines at least one compensation grayscale value corresponding to the resultant value. The 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. 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.
