Abstract
A display device includes a display panel and a readout circuit. The display panel includes light emitting pixels and light sensing pixels. Each of the light emitting pixels includes a light emitting element, and each of the light sensing pixels includes a photoelectric conversion element. The readout circuit is connected to the light sensing pixels through readout lines. When operating in a photoplethysmography (PPG) sensing mode, the readout circuit may receive first sensing current from one or more of the light sensing pixels in a first sensing area adjacent to a sensing light emitting area that emits light, may receive second sensing current from one or more the light sensing pixels in a second sensing area spaced from the first sensing area, and may generate a PPG signal based on the first sensing current and the second sensing current.
