摘要 |
<P>PROBLEM TO BE SOLVED: To simplify the configuration of a current output type D/A converter. <P>SOLUTION: A data line driving circuit 200 comprises D/A conversion units U1-Un. Each of the D/A conversion units U1-Un comprises a voltage D/A converter 220 for generating an analog voltage signal Sv based on image data, a V/I converting circuit 230 for converting the analog voltage signal Sv into an analog current signal Si, and a voltage/current selector 240 for selecting one of the analog voltage signal Sv and the analog current signal Si based on a precharge control circuit CTL. The analog voltage signal Sv output from the voltage/current selector 240 then operates as a precharge voltage and the analog current signal Si operates as a driving current of an OLED element. <P>COPYRIGHT: (C)2008,JPO&INPIT |
