A display panel includes a plurality of pixels disposed on a first panel substrate of first and second panel substrates that face each other and cooperate to display an image. The second panel substrate includes a base substrate, a read-out line, a first insulating layer, a scan line, a switching device, and a light sensor. The read-out line is disposed on the base substrate and extended in a direction. The first insulating layer is disposed on the read-out line. The scan line is extended to cross the read-out line and disposed on the first insulating layer. The switching device includes a first electrode connected to the scan line, a second electrode connected to a read-out line, and a third electrode spaced apart from the second electrode. The light sensor is structured to selectively detect lights of predetermined wavelengths and connected to the third electrode of the switching device.

Display panel having embedded light sensors

In a display apparatus, a first substrate includes a plurality of pixels and a plurality of first signal lines connected to the pixels. A second substrate includes a plurality of sensors and a plurality of second signal lines connected to the sensors and extended in a direction in which the first signal lines are extended. Each of the second signal lines is disposed between two first signal lines adjacent to each other and disposed closer to a center line, which divides an area between the two first signal lines into two portions, than the two first signal lines. Thus, signal interference between the first and second signal lines may be reduced, thereby preventing mis-operation or malfunction of the display apparatus.

Display apparatus with reduced signal interference

In a display apparatus, one frame includes a first sub-frame in which a previous image is held and a second sub-frame in which a present image is displayed. A plurality of sensors recognizes an object disposed on a display panel and sequentially outputs sensing signals in response to scan signals. Sensing signals are divided into a first sensing signal read out during a first sub-frame and a second sensing signal read out during a second sub-frame, and a control circuit generates a noise free signal using the first and second sensing signals. Thus, a coordinate value indicating the position of the object may be generated based on the noise free signal, thereby preventing mis-operation or malfunction caused by the noise.

Display apparatus

A display device includes a first substrate with pixels for displaying an image and a first wire transmitting a common voltage received from an outside source. A second substrate includes a second wire transmitting the common voltage received from the outside source and a common electrode receiving the common voltage from the first wire and the second wire. Conductive spacers are formed between the first wire and the common electrode in correspondence with a part of an area where the first wire is formed, and electrically connect the first wire to the common electrode.

Display device with display panel having sensors therein

In a display apparatus, a light sensor of a display includes a light sensing layer, a source electrode, a drain electrode, an insulating layer, and a gate electrode to sense light from an external source. The light sensing layer is disposed on the substrate to sense light, and the source and drain electrodes are disposed on the light sensing layer and are covered by the insulating layer. The gate electrode is disposed on the insulating layer. An edge of the gate electrode is disposed on the light sensing layer at least in an area where the light sensing layer is overlapped with the source and drain electrodes.
