Abstract
A display driver includes a first latch storing first image data, a second latch storing second image data, and a buffer unit including a plurality of output buffers outputting a source voltage corresponding to the first image data. Each of the plurality of output buffers includes an input stage, an output stage, and a pre-charge circuit connected between the input stage and the output stage. A pre-charge control unit compares the first image data with the second image data to control the pre-charge circuit.
