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: A display device can include a light emitting element, and a pixel driving circuit connected to the light emitting element and configured to include first to fourth nodes. The pixel driving circuit can include a driving transistor connected to the first to third nodes, a plurality of switching transistors, and a storage capacitor. Among the plurality of switching transistors, the switching transistor connected to a source node of the driving transistor is controlled by a second scan signal, and is configured to apply a data voltage to the source node of the driving transistor. The second scan signal can be applied one or more times during one frame.

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.
