<p><P>PROBLEM TO BE SOLVED: To prevent an application sequence of a gradation voltage in each of a plurality of signal line driving circuits from not being in conformity to one another in an electronic apparatus, in which the plurality of signal line driving circuits executes update control of the application sequence of the gradation voltage to each signal line in a wiring block. <P>SOLUTION: Individual control circuits 30 of electro-optical devices 100R, 100G and 100B execute update control of an application sequence of a gradation voltage in an asynchronous manner with one another. A host CPU 60 supplies an initialization synchronizing signal ISYNC with respect to the individual control circuits 30 of the electro-optical devices 100R, 100G and 100B at a timing that occurs in a cycle of an integer multiple of an update cycle of the application sequence of the gradation voltage and is synchronized with a vertical synchronization signal VSYNC, and simultaneously initializes operation of the update control of the application sequence of the gradation voltage in the individual control circuits 30 of the electro-optical devices 100R, 100G and 100B. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
