Patent ID: 8896572

Claim:
A display device, comprising: a first sensor data line extending in a row direction and configured to transmit a first sensing signal, according to a touch to a first output unit, via a first sensing switching element; a second sensor data line extending in a column direction and configured to transmit a second sensing signal, according to a touch to a second output unit, via a second sensing switching element; a first reset switching element connected between the first sensor data line and a reset voltage; a second reset switching element connected between the second sensor data line and the reset voltage, wherein the first sensing switching element and the second reset switching element are simultaneously turned on during a first period, and wherein the second sensing switching element and the first reset switching element are simultaneously turned on during a second period, wherein the first output unit comprises: a first amplifier including a first inversion terminal and a first output terminal; a first capacitor connected between the first inversion terminal and the first output terminal of the first amplifier; and a third reset switching element connected in parallel to the first capacitor, and wherein the second output unit comprises: a second amplifier including a second inversion terminal and a second output terminal; a second capacitor connected between the second inversion terminal and the second output terminal of the second amplifier; and a fourth reset switching element connected in parallel to the second capacitor, wherein the first sensor switching element and the third reset switching element are simultaneously turned off during a third period between the first period and the second period, and the first output voltage is processed during the third period, and wherein the second sensor switching element and the fourth reset switching element are simultaneously turned off during a fourth period between the second period and the first period, and the second output voltage is processed during the fourth period.
