Abstract:
1. A display panel driver for being supplied with digital data for displaying red, green, and blue on a display panel having display elements, correcting differences between light-emission characteristics of the display elements for red, green, and blue using m gradation voltages for each of red, green, and blue, and generating and outputting drive voltages for data lines of the display panel, said display panel driver comprising: voltage generating means for generating reference voltages, said voltage generating means having a plurality of resistors connected in series between a first voltage power supply which supplies high-voltages and a second power supply which supplies low-voltage, and n reference voltage terminals, which are more than said m gradation voltages, connected to respective junctions at which said resistors are connected; and voltage selecting means for selecting and outputting m red gradation voltages, m green gradation voltages, and m blue gradation voltages from the reference voltages supplied from said n reference voltage terminals.
