A liquid crystal display, comprising a plurality of pixels, a data driver and a sense signal generator, where each of the pixels comprises a switch coupled to a data line and a liquid crystal capacitor. The liquid crystal capacitor is coupled to the switch and its capacitance is varied in response to external touch. The gate driver provides a gate signal to the pixel and the data driver provides data voltage to a data line. The sense signal generator generates a sensing signal by sensing a capacitance of the liquid crystal capacitor.
