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.

An organic light emitting display comprising:
- a gate driving circuit that supplies 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,
- the luminance control unit including:
- a first switching element electrically connected to each of the plurality of gate lines;
- a second switching element electrically connected between each of the plurality of gate lines and the power supply line;
- and
- a luminance control signal line electrically connected to the first switching element and the second switching element.
An organic light emitting display comprising:
- a luminance control unit including a part of a plurality of gate lines electrically connecting a gate driving circuit and a display panel and a part of a power supply line,
- the luminance control unit further including:
- a first switching element that determines whether or not to supply a gate signal including a gate high voltage to each of the plurality of gate lines during a particular period of time;
- a second switching element that supplies a gate low voltage to each of the plurality of gate lines during a particular period of time;
- and
- a luminance control signal line electrically connected to the first switching element and the second switching element.
