Embodiments of a current range control circuit, data driver and organic light emitting display are disclosed, wherein the current range control circuit is configured to adjust a range of an input current in the data driver according to a type of display device. One embodiment of the data driver comprises a data latch configured to sequentially receive video data according to a latch control signal and output the video data in parallel. A multiplexer multiplexes the outputted video data, and a D/A converter converts the multiplexed video data into analog current signals. The data driver further comprises a current range control circuit configured to receive data current signals from the D/A converter and output a demultiplexed data current. The current range control circuit is further configured to adjust a range of the data current according to a current range control signal.
