Abstract: A display device includes a display panel including a plurality of pixels, an illuminance sensor to measure illuminance, and a display controller which includes a processor a brightness controllers. The processor calculates an external illuminance value with reference to a signal from the illuminance sensor. The brightness controller turns off at least one of the pixels and controls the brightness of the display panel when the calculated external illuminance value is in a first region. The first region may be, for example, in a mesopic region.

Abstract: A display device includes: a display panel; an emission driver; a scan driver; and a timing controller. The display panel includes light emitting pixels and photosensitive pixels, where the photosensitive pixels are operated in an initialization period, a light exposure period and a sensing period. The emission driver supplies emission control signals to emission control lines connected to the light emitting pixels, based on an emission start signal. The scan driver supplies scan signals to scan lines connected to the light emitting pixels and the photosensitive pixels, based on a scan start signal. The timing controller generates the emission start signal having a single pulse of a gate-off level and the scan start signal having a single pulse of a gate-on level in a last frame period among frame periods corresponding to the light exposure period and in each of frame periods corresponding to the sensing period.

Abstract: A display device comprises a display panel which comprises scan lines, sensing lines, pixels electrically connected to each of the scan lines, and photo sensors electrically to each of the scan lines and the sensing lines, a scan driver which outputs scan signals to the scan lines according to a scan control signal, a timing controller which outputs the scan control signal to the scan driver, and a readout circuit which receives light sensing signals of the photo sensors from the sensing lines. The timing controller sets a frame frequency of the scan control signal to a first frame frequency in a first mode in which the display panel displays an image. The timing controller sets the frame frequency of the scan control signal to a second frame frequency in a second mode in which the photo sensors sense a fingerprint.
