Abstract: A display driver and a driving method thereof is disclosed. The display driver includes at least one first latch, at least one second latch, an output buffer, and a comparator. The first latch receives input data. The input terminal of the second latch is coupled to the output terminal of the first latch. The output buffer, including at least one variable current source, is coupled to the second latch. The comparator is coupled to the first latch, the second latch, and the variable current source. The comparator generates at least one control signal of the variable current source.
