ABSTRACT:
A data driving circuit and method for an organic light emitting diode display. Data lines transmit first digital data in a first cycle, and subsequent digital data in a second cycle. A D/A converter electrically connected to the data lines converts the first digital data to first analog data, and converts the subsequent digital data to second analog data. Each analog sampling storage circuit electrically coupled to the D/A converter, in the first cycle, stores the first analog data, in the second cycle, outputs the first analog data and stores the second analog data, and in a third cycle, outputs the second analog data.
