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 including unit areas. Each of the unit areas includes pixels arranged in a matrix formation; and data lines (DLs) connected to the pixels. The display device is configured to: apply data voltages of a same polarity to first DLs positioned between adjacent pixel columns; and apply DVs of different polarities to second DLs positioned at respective sides of each pixel column. Each of the pixels is connected to one of the second DLs. A connection direction between the pixels and the DLs in each of a plurality of pixel rows is changed in a determined pixel column interval. Connection directions between the pixels and the DLs are opposite each other in odd-numbered pixel rows adjacent in a column direction. Connection directions between the pixels and the DLs are opposite each other in even-numbered pixel rows adjacent in the column direction.

During the first frame, each of the pixels provides a second capacitor with the right eye image signal, and a first capacitor with the left eye image signal. During the second frame, each of the pixels provides the first capacitor with the right eye image signal, and the second capacitor with the left eye image signal. A backlight unit maintains a turn-on state during the first and second frames.
