Abstract: A liquid crystal display includes: a display panel; a signal controller configured to receive an input image signal and an input control signal, output an output image signal and an output control signal, and determine a charge sharing between two or more data lines having voltages in the same polarity; and a data driver configured to convert, based on the output control signal, the image signal into data voltages to be supplied to the data lines connected to the pixels, the data voltages having positive levels and negative levels. The data driver is further configured to perform a first charge sharing by short-circuiting first and second data lines that are adjacent to each other, and a second charge sharing by short-circuiting third and fourth data lines having data voltages in the same polarity, wherein the first charge sharing and the second charge sharing may not temporally overlap with each other.

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.
