Patent ID: 8471827

Claim:
A display device, comprising: at least one row sensor data line extending in a row direction; at least one column sensor data line extending in a column direction; a first sensing unit that is connected to the row sensor data line, the first sensing unit to output a first sensing signal on a first output terminal according to a touch; a second sensing unit that is connected to the column sensor data line, the second sensing unit to output a second sensing signal on a second output terminal according to the touch; a sensing signal processor to alternately apply a reset voltage to the row sensor data line and the column sensor data line, generate a sensing data signal according to the first sensing signal and the second sensing signal, initialize the first output terminal to a reference voltage while the reset voltage is applied to the row sensor data line, and initialize the second output terminal to the reference voltage while the reset voltage is applied to the column sensor data line; and a touch determiner to process the sensing data signal to generate touch information, wherein the sensing signal processor comprises: a first output unit to process the first sensing signal during a first period and apply the reset voltage to the row sensor data line during a second period; and a second output unit to process the second sensing signal during the second period and apply the reset voltage to the column sensor data line during the first period.
