Technical Examples

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. Therefore, electrical coupling between devices is reduced and aperture ratio is increased, thereby enhancing a display quality.
