Abstract: A data driver includes a first latch, a second latch, a digital-to-analog converter, and an output buffer. The first latch sequentially stores first line data in response to a first sampling signal and outputs the stored data in parallel. The second latch sequentially stores second line data in response to a second sampling signal and outputs the stored data in parallel. The digital-to-analog converter converts the parallel data provided from one of the first and second latches to data voltages. The output buffer outputs the data voltages in response to a delay clock.
