<P>PROBLEM TO BE SOLVED: To simplify the configuration of a signal output circuit outputting a video signal to a signal line, in adopting a precharge technique. <P>SOLUTION: The signal output circuit 60 is configured so that selection switches 61-r, 61-g and 61-b are used in common for selecting a signal voltage Vsig and a first reference potential Vofs1 and selection switches 62-r, 62-g and 62-b are used in common for selecting a second reference potential Vofs2 and a precharge potential Psig. Thus, in adopting the precharge technique, exclusive wiring transmitting the precharge potential Psig and an exclusive selection switch for selectively outputting the precharge potential Psig to the signal line 33 are dispensed with to simplify the circuit configuration of the signal output circuit 60. <P>COPYRIGHT: (C)2009,JPO&INPIT |
