Abstract
A display device includes a display panel and a readout circuit. The display panel includes a pixel including a light emitting element, a sensor including a light sensing element, and a dummy sensor. The readout circuit outputs a readout signal based on a sensing signal received from the sensor and a dummy sensing signal received from the dummy sensor. The readout circuit includes a reference current conveyor that outputs a reference signal corresponding to the dummy sensing signal, and a sensing circuit that outputs the readout signal corresponding to a difference between the sensing signal and the reference signal.
