Abstract: A display driver circuit includes a comparator that is configured to compare first pixel data of a plurality of pixel data with second pixel data of the plurality of pixel data, the plurality of pixel data respectively corresponding to a plurality of pixels connected to a data line, a pre-emphasis controller configured to calculate an offset based on a compare result of the comparator and gamma segment points, which are adjacent to the second pixel data, from among a plurality of gamma segment points used as a reference for dividing the plurality of pixel data, a calculator configured to calculate pre-emphasis pixel data based on the second pixel data and the offset, and an output circuit configured to transmit a pre-emphasis gray scale voltage corresponding to the pre-emphasis pixel data and a target gray scale voltage corresponding to the second pixel data to a display panel through the data line.
