摘要：
A liquid crystal display includes a liquid crystal panel that has a plurality of pixels and a plurality of sensors, and a touch sensing circuit that compares a sensing voltage detected by at least one sensor with a reference voltage that corresponds to the at least one sensor to determine the at least one sensor is touched. A level of the reference voltage is calibrated by taking operation characteristics of the sensors into consideration.
