Abstract
A display driver that receives display line data of plural display lines to perform drive control on a display panel includes a line memory for storing display line data which is supplied from the outside. The display driver includes a logic circuit that controls write and read-out of the display line data in and from the line memory, and sorts pixel data of the display line data using read out data from the line memory, to generate display drive data. Drive circuits drive the display panel in units of display lines based on the drive data which is output from the logic circuit. The drive circuits are separately arranged on both sides of the logic circuit and the line memory which are interposed therebetween. The storage capacity of the line memory corresponds to the number of lines smaller than the number of display lines of a display frame.
