Abstract
A display driver is connectable with and serves to activate an active matrix type display panel having a plurality of source lines wired to run in an up-and-down direction and a plurality of gate lines wired to run in left and right directions when viewed from a direction perpendicular to a substrate, and a plurality of pixels respectively arranged at intersections where the source and gate lines intersect with one another; electric charges corresponding to display data are transmitted from the source lines to the pixels selected by the driven gate line. The display driver includes a circuit capable of adjusting, in amplitude, first gate drive circuits operable to drive, of the plurality of gate lines, gate lines wired from the left, and second gate drive circuits operable to drive gate lines wired from the right independently of one another.
