Patent ID: 8614702

Claim:
A display controller and driver device for use with a display panel having a plurality of scanning lines and a plurality of signal lines arranged to cross the a plurality of scanning lines, the display controller and driver device comprising: a plurality of external terminals; a drive circuit which provides voltages to the external terminals to be applied to the plurality of signal lines of the display panel on a time division basis, and for each of red, green and blue colors in accordance with a predetermined timing signal; and a register to set display modes, said register configured to set a first value and a second value, wherein the first value enables two or more groups of the drive circuit to supply the voltages at a same timing, and the second value enables the two or more groups of the drive circuit to supply the voltages at mutually different timings in which the sequence of outputs of the different groups is periodically varied, wherein a latch circuit for holding image data to be displayed is disposed at a stage preceding the drive circuit, and wherein output timings of different ones of the two or more groups are staggered by transferring image data to be transferred from the latch circuit to the drive circuit, in synchronization with clock signals each of which differ in timing from one another.
