<P>PROBLEM TO BE SOLVED: To perform high-speed current drive of light emitting elements formed on a display panel, even when the load on the display panel has become large, as a screen is enlarged, relating to the display panel. <P>SOLUTION: It becomes possible to supply an arbitrary quantity of current to the light emitting elements EL, by allowing an application voltage source VA1 and a charge storage capacity C1, to be connected to the light emitting elements EL via a switch S1, and supplying a control signal W1 of a predetermined cycle to the switch S1 by a control circuit, to perform arbitrary amount of charge transfer, to the charge storage capacity C1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
