Abstract
Disclosed is a touch sensor including a touch panel including driving lines and sensing lines, a node capacitor being formed between the neighboring driving and sensing lines, and a sensing unit electrically connected to the sensing lines to sense variation in the capacitance of the node capacitor. The sensing unit includes an amplifier including a first input terminal configured to receive a signal from any one of the sensing lines, a second input terminal connected to a first power source, and an output terminal, a feedback capacitor connected between the first input terminal and the output terminal, and a current controller connected in parallel to the feedback capacitor between the first input terminal and the output terminal to control current flowing to the feedback capacitor.
