Abstract
A data driver to display an image with desired brightness, and an organic light emitting display device using the same. The data driver includes a register to temporarily store external data; a voltage digital-analog converter to generate a data voltage corresponding to the data stored in the register part; a current digital-analog converter to generate a data current corresponding to the data stored in the register part; a buffer part to supply the data voltage as a data signal to pixels via a data line; a data control unit to receive a pixel current corresponding to the data voltage from the pixel via the data line and to control a digital value of the data stored in the register part; and a selection unit to selectively couple the data line with either of the buffer part or the data control unit.
