LIQUID CRYSTAL DISPLAY WITH INTEGRATED TOUCH SENSOR
First Claim
1. A liquid crystal display integrated with a touch sensor, the display comprising,a first substrate including pixels connected to gate wires and data wires;
- a second substrate positioned to face the first substrate;
a plurality of common electrodes corresponding to the pixels;
a plurality of sensing electrodes on the second substrate;
a liquid crystal layer between the first substrate and the second substrate;
a gate drive unit driven corresponding to a gate control signal and configured to supply a gate signal to the pixels through the gate wires;
a common electrode drive unit configured to supply a touch driving signal to the common electrodes during a touch driving period; and
a control unit configured to supply a gate control signal synchronized with the touch driving signal to the gate drive unit.
