Abstract:
1. An organic light emitting display comprising: a scan driver connected to a plurality of scan lines; a data driver connected to a plurality of first data lines; a plurality of sets of second data lines; a plurality of demultiplexers, each of the demultiplexers being connected at its input to a respective one of the first data lines and at its outputs to a respective one set of the second data lines; an image display device connected to the scan lines and the second data lines, the image display device having a plurality of pixels, each of the pixels comprising an organic light emitting diode and a first transistor, the first transistor allowing an electric current to flow therethrough to the organic light emitting diode when the first transistor is turned on, the plurality of pixels comprising red pixels, green pixels, and blue pixels; a common power supply connected to the plurality of pixels, the common power supply being electrically connected to the first transistor of at least one of the pixels when an electric current flows to the organic light emitting diode of the at least one of the pixels; at least one initialization power supply, selectively connected to the first transistors of the pixels, wherein the initialization power supply is configured to generate three different voltages and to provide one of the three generated voltages to the first transistor of each of the pixels of the image display device, the at least one initialization power supply being electrically disconnected from the first transistors of the pixels when electric currents flow to the organic light emitting diodes of the pixels, the at least one initialization power supply comprising: a plurality of data capacitors, each of the data capacitors being coupled with a respective one of the second data lines.
