Abstract
A data driver and an organic light emitting display having the same. The data driver has a switch unit provided between output terminals of respective output buffers that are provided in the data driver and data lines corresponding thereto. Here, the switch unit is also coupled to a source for providing a middle voltage, and allows the output terminals of the output buffers to be coupled to receive the middle voltage before data signals are output from the data driver by the operation of the switch unit, making it possible to improve the slew rate of the output buffer and to reduce power consumption, and an organic light emitting display having the same. The switch unit may includes a first switch coupled between the source for providing the middle voltage and the output terminals, and a second switch coupled between the output terminals and the respective data lines.
