摘要： A liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer. The first substrate includes a plurality of pixels and a plurality of sensing parts. Each of the sensing parts generates an output signal containing location information in response to an input signal. The location information indicates a location where the input signal is inputted. The second substrate is connected to the first substrate. The second substrate faces the first substrate. The liquid crystal layer is interposed between the first substrate and the second substrate. The liquid crystal display device needs no additional touch panel, so that no air space exists between the liquid crystal display panel and the touch panel. Therefore, a display quality is enhanced.

摘要： 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.

摘要： In a light sensor test unit, a test circuit is built in a display panel and connected to an output node of a light sensor which senses an intensity of an external light. When external light having a predetermined intensity is provided to the light sensor, the test circuit outputs a driving signal in response to a sensing signal output from the output node. A test pixel part includes pixels selected from a plurality of pixels arranged in the display panel and receives the driving signal from the test circuit to display a gray-scale corresponding to the driving signal. A brightness measurer measures a brightness corresponding to the gray-scale displayed in the test pixel part to compare the measured brightness with a predetermined brightness, thereby testing whether the light sensor built in the display panel is normally operated.
