    Abstract: A wiring-disconnection detecting circuit includes a low-power voltage supply, a monitoring wiring, and a wiring-disconnection determiner. The low-power voltage supply supplies a low-power voltage to a low-power voltage wiring that extends along a periphery of a display panel in a normal operating mode of the display panel and supplies a test voltage to the low-power voltage wiring in a wiring-disconnection detecting mode of the display panel. The monitoring wiring includes a first end connected to one point of the low-power voltage wiring and a second end at which a feedback voltage corresponding to the test voltage is output in the wiring-disconnection detecting mode. The wiring-disconnection determiner receives the feedback voltage from the second end, measures an RC delay of the feedback voltage, and determines that the low-power voltage wiring is disconnected when the RC delay is larger than a predetermined reference value.

    Abstract: A display panel includes a base layer, a circuit layer, and a pixel layer. The base layer includes a plurality of light emitting areas, and a plurality of transmitting areas to transmit light incident thereto. The circuit layer includes a plurality of switching devices disposed on the light emitting areas, and a plurality of photosensors disposed on the transmitting areas. The pixel layer includes a light emitting element to emit light based on reception of a current from at least one of the plurality of switching devices. The light emitting element overlaps with one of the plurality of light emitting areas. At least one of the plurality of photosensors is configured to receive a portion of external light reflected from an external object after transmission of the external light through at least one of the plurality of transmitting areas.
