Abstract:
1. A liquid crystal display having touch sensing functionality, the liquid crystal display comprising: a scan line for transmitting a scan signal; a gate line for transmitting a gate signal; a sensing unit, electrically connected to the scan line and the gate line, for providing a first analog readout signal according to the scan signal and the gate signal, the sensing unit comprising: a second transistor having a first end directly coupled to the gate line, a gate end electrically connected to the voltage boost unit for receiving the secondary sense voltage, and a second end for outputting the first analog readout signal; and a first readout line, electrically connected to the second end of the second transistor, for transmitting the first analog readout signal; wherein capacitance of the second capacitor changes during a touch event for generating the first analog readout signal corresponding to the touch event.
