Abstract
A timing controller and an operation method thereof are provided. The timing controller is used to control a signal timing of a display panel. The timing controller includes an analysis circuit and a decision circuit. The analysis circuit analyzes the content of an image frame to obtain an analysis result. The decision circuit is coupled to the analysis circuit to receive the analysis result. The decision circuit determines a global gray level according to the analysis result. In a blanking interval in which a plurality of sub-pixel circuits of the display panel are turned off, a data voltage corresponding to the global gray level is applied to at least one data line of the display panel corresponding to the sub-pixel circuits.
