ABSTRACT:
A data driver adapted to display an image with substantially uniform brightness is provided. The data driver includes a holding latch unit including holding latches for storing data, a signal generator including digital-analog converters for receiving the data to generate data signals, a first switching unit provided between the holding latch unit and the signal generator, and a second switching unit coupled to the signal generator to transmit the data signals to data lines. The first switching unit couples the holding latches to the digital-analog converters during a horizontal period in a manner different from the manner in which the holding latches and the digital-analog converters are coupled to each other during a previous horizontal period. Therefore, errors of the digital-analog converters are diffused so that it is possible to display an image with substantially uniform brightness.
