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.

Abstract: A display apparatus includes a first substrate including a plurality of pixels, and a second substrate facing the first substrate, the second substrate comprising a sensor area and a peripheral area, the sensor area comprising a plurality of sensors. The second substrate includes an insulating layer, and a plurality of lines disposed on the insulating layer corresponding to the peripheral area and connected to the sensors. A void is formed in the insulating layer between two adjacent lines of the plurality of lines at a boundary of the sensor area and the peripheral area.
