摘要： An image display control unit in a three-dimensional image display apparatus is configured to drive gate lines and the data lines so as to provide the display panel with a left eye image signal during a first frame in which a right eye image signal is displayed on the display panel, and with the right eye image signal during a second frame in which the left eye image signal is displayed on the display panel. 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.

摘要： 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.
