Abstract: A display device including a plurality of sensing units, a plurality of first sensing signal lines, a first output unit, a first sensing output line, and a sensing signal processor. The sensing units are arranged in a matrix and generate a detection signal according to user contact. The first sensing signal lines transfer the detection signal of the sensing unit arranged in a first direction. The second sensing signal lines transfer the detection signal of the sensing units arranged in a second direction that is perpendicular to the first direction. The first output unit sequentially outputs the detection signals of the first sensing signal lines. The first sensing output line extends in the second direction for transferring the detection signal of the first output unit. The sensing signal processor determines whether contact is made or not by processing the detection signals of the first sensing signal lines and the second sensing signal lines. The non-display area of the liquid crystal panel assembly can be reduced by sequentially outputting the sensing data signals of the row and column sensing signal lines through the small amount of wiring. Therefore, an IC can be reduced in size.

Abstract: A light sensing panel includes a scan line transmitting a scan signal, a power source line transmitting a bias voltage, a readout line transmitting a light sensing signal and a light sensing device. The light sensing device includes a control electrode that is electrically connected to the scan line to receive the scan signal, a first current electrode that is electrically connected to the power source line to receive the bias voltage, and a second current electrode that is electrically connected to the readout line to apply a light sensing signal to the readout line when the light sensing signal senses an external light. The light sensing panel requires only one thin film transistor in order to detect a position wherein the external light is incident.
