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 a plurality of sub-frames, the organic light emitting diode display comprising:
- 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 to at least two of said scan lines during each of the sub-frames, the at least two of the scan lines receiving the scan signals at different time periods in the each of the sub-frames;
- a data driver to supply data signals corresponding to said scan signals;
- and
- a plurality of first power sources connected to said pixels, one of the first power sources being connected to anode electrodes of light emitting devices of pixels connected to the at least two of said scan lines, a number of the first power sources being the same as a number of the sub-frames.
A method of driving an organic light emitting diode display including a plurality of scan lines provided in a pixel portion, comprising:
- dividing one frame into at least two sub-frames;
- and
- supplying scan signals to at least two of the scan lines during each of the sub-frames, the at least two of the scan lines receiving the scan signals at different time periods in the each of the sub-frames, pixels connected to the at least two of the scan lines not emitting light during the each of the sub-frames.
A method of driving an organic light emitting diode display including a plurality of scan lines provided in a pixel portion, comprising:
- dividing one frame into a plurality of sub-frames;
- and
- supplying scan signals to at least two of the scan lines during each of the sub-frames, the at least two of the scan lines receiving the scan signals at different time periods in the each of the sub-frames, pixels connected to the at least two of the scan lines being in a non-emission state during the each of the sub-frame, rest of the pixels being in an emission state during the each of the sub-frame.
A method of driving an organic light emitting diode display including a plurality of scan lines provided in a pixel portion, comprising:
- dividing one frame into a plurality of sub-frames;
- setting a number of first power sources connected to anode electrodes of light emitting devices provided in pixels to be equal to a number of the sub-frames;
- supplying scan signals to at least two of the scan lines during each of the sub-frames the at least two of the scan lines receiving the scan signals at different time periods in the each of the sub-frames;
- and
- supplying data signals to pixels connected to the at least two of the scan lines during the each of the sub-frame, the pixels not emitting light during the each of the sub-frames.
