PIXEL AND ORGANIC LIGHT EMITTING DISPLAY USING THE PIXEL

摘要

PURPOSE: A pixel and an organic electroluminescent display device thereof are provided to prevent the generation of light which is not required for an organic light emitting diode by setting initial power to a voltage which is a level capable of enabling an organic light emitting diode to be turned off. CONSTITUTION: A scan driving part(110) receives a scan driving control signal(SCS) from a timing control part(150). A data driving part(120) receives a data driving control signal(DCS) from the timing control part. The timing control part generates the data driving control signal and the scan driving control signal corresponding to synchronization signals which are supplied from the outside. The timing control part supplies data supplied from the outside to the data driving part. A pixel part(130) receives a first power source(ELVDD), a second power source(ELVSS), a reference power source(Vref), and an initial power source(Vint) and supplies them to each pixel.
