Abstract:
1. A liquid crystal display, comprising: pixels; a signal controller configured to receive an input image signal and an input control signal and to output a processing image signal and a control signal; a data driver configured to change the processing image signal to data voltages based on the control signal; to supply the data voltages to the pixels; and to share charges of an odd channel data voltage and an even channel data voltage which have different polarities; a first charge sharing unit configured to output a first charge share control signal; and a second charge sharing unit configured to output a second charge share control signal, wherein: the input control signal comprises an inversion signal such that charge sharing occurs only when a polarity inversion of the odd channel data voltage or a polarity inversion of the even channel data voltage occurs at room temperature on the basis of the inversion signal and the first charge share control signal; the input control signal comprises a horizontal synchronizing signal such that the charges are shared every 1 horizontal period (1 H) on the basis of the horizontal synchronizing signal and the second charge share control signal even if there is no inversion of the polarity of the odd channel data voltage or the polarity of the even channel data voltage, at a temperature less than the room temperature; and at room temperature, the first charge share control signal has a high value and the second charge share control signal has a low value and, at a temperature less than the room temperature, the first charge share control signal has the low value and the second charge share control signal has the high value.
