<P>PROBLEM TO BE SOLVED: To reduce power consumption without deteriorating image quality in response to line-sequential scanning. <P>SOLUTION: Concerning a display data signal supplied to a display panel part, the maximum gray scale value in a range of a predetermined line count (e.g. a range of line count equivalent to one frame) ascended from the current horizontal line is detected at intervals of one line period. At intervals of one line period, power supply voltage information for light emission drive of an organic EL element is generated using the detected maximum gray scale value, and the power supply voltage value supplied to each pixel circuit of the display panel part is changed at intervals of one line period based on the generated power supply voltage value information. <P>COPYRIGHT: (C)2009,JPO&INPIT |
