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 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.
