TIMING CONTROLLER TO REDUCE FLICKER AND METHOD OF OPERATING DISPLAY DEVICE INCLUDING THE SAME

A timing controller to reduce a flicker in a display device is provided. The timing controller includes a line pattern detector and a frame pattern detector. The line pattern detector divides received data into a plurality of unit blocks and detects a line polarity of each of a plurality of horizontal lines included in each of the unit blocks. The frame pattern detector generates a polarity control signal to control a data inversion method based on a frame image pattern detected based on line polarities of the respective horizontal lines.
