Abstract
An organic light emitting diode display and a driving method thereof, has an image displayed with uniform brightness. The method of driving a organic light emitting diode display, includes dividing one frame into one or more sub-frames, and supplying scan signals in sequence to some of plural scan lines provided in a pixel portion per sub-frame. The scan lines receiving the scan signals are differently set per sub-frame. With this configuration, an image is displayed with uniform brightness.
Claims35
An organic light emitting diode display capable of dividing one frame into one or more sub-frames, the organic light emitting diode display comprises:
- a plurality of scan lines;
- a plurality of data lines;
- a plurality of pixels connected to said scan lines and said data lines;
- a scan driver to supply scan signals in sequence to at least some of said scan lines per sub-frame;
- a data driver to supply data signals corresponding to said scan signals;
- and
- a plurality of first power sources connected to anode electrodes of light emitting devices provided in said pixels and provided as the same number as the sub-frames, with the scan lines receiving the scan signals being differently set per sub-frame.
A method of driving an organic light emitting diode display, comprising:
- dividing one frame into at least one sub-frame;
- and
- supplying scan signals in sequence to some of a plurality of scan lines provided in a pixel portion per sub-frame, with the scan lines receiving said scan signals are differently set per sub-frame.
A method of driving an organic light emitting diode display, comprising:
- dividing one frame into three or more sub-frames;
- and
- setting some pixels of a pixel portion as a non-emission state and the rest of the pixels as an emission state per sub-frame.
A method of driving an organic light emitting diode display, comprising:
- dividing one frame into one or more sub-frames;
- setting the number of first power sources connected to an anode electrode of a light emitting device provided in a pixel to be equal to the number of sub-frames;
- and
- supplying data signals to some pixels provided in a pixel portion per sub-frame, with the pixels receiving the data signals do not emit light during each sub-frame.
