1. A data driver comprising:
output channels configured to output data signals;
output controllers configured to selectively output data signals having a first arrangement or data signals having a second arrangement to output channel groups each of which includes N output channels in response to arrangement control signals, where N is a positive integer greater than or equal to 2; and
a control signal generator configured to output the arrangement control signals to the output controllers to control the output controllers,
wherein a first output controller among the output controllers is configured to selectively output data signals for a first color to a first output channel or a third output channel in response to one of the arrangement control signals;
wherein the first output controller is configured to selectively output data signals for a second color to the first output channel or the third output channel in response to the one of the arrangement signals; and
wherein the first output controller is configured to output data signals for a third color to a second output channel and a fourth output channel.
