ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD THREROF

摘要

The present invention relates to an organic light emitting display device which improves display quality. The organic light emitting display device of the present invention includes pixels which are located in a region divided by scan lines and data lines and control current flowing from a first power source to a second power source via the light emitting diode by corresponding a data signal; a power source part which supplies an initialization power source from a driving transistor included in each pixel. An initial power source part controls the initialization power source to maintain a constant voltage different to the second power source.
