Abstract: Provided is an organic light emitting display. The organic light emitting display can include a gate driving circuit configured to supply a gate signal through each of a plurality of gate lines connected to a display panel, and a luminance control unit between the gate driving circuit and the display panel and electrically connected to the plurality of gate lines and a power supply line. A gate signal is supplied to the pixels in a distributed manner during a plurality of refresh periods. Therefore, it is possible to reduce a luminance decrease in the pixels during the entire refresh period.

Abstract: The present disclosure relates to a sensing device and a display device including the sensing device. The sensing device includes a transducer including first and second driving electrodes and a piezoelectric material layer; first and second transmission transistors for alternatively supplying first and second driving voltages to the first driving electrode; and first and second reception transistors electrically connected between a readout line and a power supply line to which a power supply voltage is supplied. During an interval in which at least one pixel is driven, the first and second driving voltages are DC voltages with a voltage level different from each other, and the first and second transmission transistors repeat turn-on and turn-off at a timing different from each other. Through this, it is possible to reduce unnecessary power consumption, and therefore, a large area fingerprint sensor can be more efficiently implemented.

Abstract: Provided is an organic light emitting display (OLED) device that can include a timing controller configured to generate control signals to be applied to a plurality of pixels, each pixel including a pixel driving circuit. An adjusted initialization voltage is input to a circuit driving circuit of the OLED device during an initialization period. Thus, a delay of a current flowing in an organic light emitting diode can be improved such that a flicker phenomenon can be suppressed or minimized.
