Abstract:
In a touch sensible display device, a first sensing unit is connected to a row sensor data line and outputs a first sensing signal according to a touch, and a second sensing unit is connected to a column sensor data line and outputs a second sensing signal according to the touch. A sensing signal processor alternately applies a reset voltage to the row sensor data line and the column sensor data line and generates a sensing data signal according to the first sensing signal and the second sensing signal, and a touch determiner processes a sensing data signal to generate touch information.
