Abstract:
A touch sensor includes a touch panel, a driver for supplying a driving signal to each of driving lines of the touch panel, and a sensor electrically connected to sensing lines of the touch panel, for detecting capacitance of a node capacitor of the touch panel, wherein the sensor includes a first amplifier including a first input terminal, a second input terminal, and an output terminal, the first input terminal being connected to the corresponding sensing line, a feedback capacitor connected between the output terminal and the first input terminal of the first amplifier, and an inverting amplifier for invert-amplifying an output signal of the output terminal of the first amplifier and supplying the invert-amplified output signal to the second input terminal of the first amplifier.
