Abstract
A display apparatus includes a display panel, sensor circuits, and a detection circuit. Each sensor circuit senses at least two external signals different from each other and outputs a sensing signal. The detection circuit receives the sensing signal to detect a position to which the external signals are applied. Each sensor circuit includes sensors commonly connected to an output terminal, a scan line which receives a scan signal, a capacitor disposed between the scan line and the output terminal, charged with a first voltage in response to the scan signal, and charged with a second voltage greater than the first voltage in response to the current signal after the scan line is floated, a switching device which outputs the sensing signal in response to the second voltage, and a readout line which applies the sensing signal output from the switching device to the detection circuit.
