Abstract: A controller controls the driving frequency and voltages for a display device. If image data corresponds to a moving picture, the controller drives a data driver and a gate driver at a moving picture frequency. If image data corresponds to a still image, drives the data driver and the gate driver at a still image frequency lower frequency than the moving picture frequency. When the still image is to be displayed, the signal controller also controls leakage current of a thin film transistor of a pixel based on a representative value of the image data, such that positive leakage current applied for a positive data voltage is equal to negative leakage current applied for a negative data voltage.

Abstract: A display device includes a display panel, a data driver, a gate driver, and a signal controller. The display panel includes a pixel connected to the gate and data lines, and the pixel includes a liquid crystal capacitor. The signal controller obtains compensation data and normal data based on input data for a still image. The signal controller apples the compensation data and normal data to the pixel during different periods of a frame. The compensation data has a value that reduces a difference of operation characteristics of liquid crystal molecules in the liquid crystal capacitor when a data voltage for the display panel changes between different polarities.
