Abstract
An organic light emitting diode display device including: a display panel including a plurality of pixels, a scan driving unit configured to supply a scan signal to the pixels via a plurality of scan lines, a data driving unit configured to supply a data signal to the pixels via a plurality of data lines, an emission driving unit configured to supply an emission control signal to the pixels via a plurality of emission control lines, and a timing control unit configured to control the scan driving unit, the data driving unit, and the emission driving unit, and to control the emission driving unit to gradually change an off-period of the emission control signal each time a number of image frames are displayed.
Claims20
An organic light emitting diode display device comprising:
- a display panel comprising a plurality of pixels;
- a scan driving unit configured to supply a scan signal to the pixels via a plurality of scan lines;
- a data driving unit configured to supply a data signal to the pixels via a plurality of data lines;
- an emission driving unit configured to supply an emission control signal to the pixels via a plurality of emission control lines;
- and
- a timing control unit configured to control the scan driving unit, the data driving unit, and the emission driving unit, the timing control unit controlling the emission driving unit to gradually and periodically change a length of time of an off-period of the emission control signal with a fixed period of a number of image frames being displayed, when frame data does not represent a stop image.
A method of driving an organic light emitting diode display device comprising a plurality of pixels, the method comprising:
- generating an emission control signal to allow the pixels to emit light;
- and
- gradually and periodically changing a length of time of an off-period of the emission control signal with a fixed period of a number of image frames being displayed, when frame data does not represent a stop image.
