<P>PROBLEM TO BE SOLVED: To provide a display apparatus for allowing a light emitting element to emit light by proper brightness gradation corresponding to display data, and to provide its driving method, a display drive and its driving method. <P>SOLUTION: A data driver 140 stores to a frame memory 146 as correction data corresponding to a variation quantity of element characteristics of a transistor Tr13 or the like for emission drive provided in each display pixel PIX (pixel drive circuit DC) arrayed on a display panel 110 by including an offset voltage generation part 143 and a voltage comparison part 145, and corrects a signal voltage (original gradation voltage Vorg) corresponding to the display data at each display pixel PIX based on the correction data to be applied on data lines Ld of each column as a correction gradation voltage Vpix by including a gradation voltage generation part 142 and a voltage regulation part 144. <P>COPYRIGHT: (C)2008,JPO&INPIT |
