摘要：
A liquid crystal display with sensing mechanism includes a data line, a sensing unit, a pixel unit, a first gate line, a second gate line, a source driver, a readout signal processing unit and a switch unit. The data line is used to deliver a data signal or a readout signal. The sensing unit is employed to generate the readout signal. The pixel unit functions to control pixel brightness according to the data signal. The first gate line delivers a first gate signal for controlling the sensing unit. The second gate line delivers a second gate signal for controlling the pixel unit. The source driver is utilized for providing the data signal. The readout signal processing unit performs a sensing position analysis on the readout signal received. The switch unit is put in use for connecting the data line with either the source driver or the readout signal processing unit.
