    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 configured to consume less power is disclosed. In one aspect, the display device includes a display panel comprising a pixel connected to a gate line and a data line, a data driver connected to the data line to apply a data voltage, and a gate driver connected to the gate line to sequentially apply a gate-on voltage. The display device additionally includes a signal controller configured to determine image data as corresponding to one of a motion picture, a still image, and a text screen. Furthermore, the signal controller is configured to drive the display panel, the data driver, and the gate driver at one of a motion picture frequency for displaying the motion picture, a still image frequency lower than the motion picture frequency for displaying the still image, and an ultra-low frequency of about 10 Hz or less for displaying the text screen.
