Patent ID: 7511691

Claim:
A display drive device for driving a display panel based on display data including display data of a plurality of different color components, wherein the display panel includes a plurality of signal lines, a plurality of scanning lines intersecting the signal lines, and display pixels which are arranged adjacent to intersections, respectively, of the signal lines with the scanning lines, said display drive device comprising: a data holding circuit which acquires the display data including the display data of the plurality of different color components and holds the display data of the plurality of different color components in parallel with one another; a first data conversion circuit which arranges, in time-series and in a predetermined arranging order, the display data of the plurality of different color components held by said data holding circuit; a display signal voltage generation circuit which generates display signal voltages, which correspond respectively to the display data of the plurality of different color components, and which are to be applied to the display pixels via the signal lines; a second data conversion circuit which is provided for each predetermined number of signal lines, the predetermined number corresponding to a number of said color components, and which sequentially selects, in the predetermined arranging order, the display signal voltages corresponding respectively to the display data of the plurality of different color components, and which applies each said selected display signal voltage to one of the predetermined number of signal lines that corresponds to the same color component as the selected display signal voltage; and a control section which changes, at a predetermined cycle, said predetermined arranging order in which the display data of the plurality of different color components are arranged by the first data conversion circuit.
