摘要： A current range control circuit for a data driver in an organic light emitting display. The data driver includes a shift register for outputting a latch control signal, a data latch for sequentially receiving video data and to output the video data in parallel, a digital to analog converter for converting the outputs of the data latch into analog currents, and the current range control circuit for outputting data currents corresponding to the analog currents and controlling the data current range using current range control signals. Because it is possible to control the range of the data currents output from the data driver, it is possible to use the data driver in various pixel circuits or electroluminescent devices by changing the current range control signals, and to make the drain voltages of the transistors that form a current mirror equal to each other to obtain the desired current values.
