Abstract
A data driver and a method of driving the same. The data driver includes a shift register for generating sampling signals; sampling latches for sampling digital data applied to output channels, respectively, in accordance with the sampling signals; holding latch units for receiving the sampled digital data of the channels from the sampling latches to hold the digital data for a first period; first digital-to-analog converters for receiving the held digital data of the channels from the holding latch units to generate currents corresponding to the digital data; a second digital-to-analog converter commonly connected to the channels and the first digital-to-analog converters to receive the digital data provided from the holding latch units for a second period and to generate correction currents for the data currents; and output stages for sampling, correcting, and driving final currents using the data currents and the correction currents.
