<P>PROBLEM TO BE SOLVED: To provide a driving structure of a liquid crystal panel, which controls light transmittance of the liquid crystal panel by voltage change. <P>SOLUTION: A feeding circuit having a primary coil of a contactless feeding circuit is provided in a feeding part, and a driving circuit having a secondary coil of the contactless feeding circuit is provided in a driving part. The driving part is separated from the feeding part, and is matched with or relatively displaced with respect to the feeding part in a matching manner. The feeding circuit is connected to a DC power and adjusts series resonance frequency of a capacitor connected in series to the primary coil by a first transmitter provided in the feeding circuit. The driving circuit adjusts parallel resonance frequency of a capacitor connected in parallel to the secondary coil by a second transmitter provided in the driving circuit, and supplies AC rectangular wave voltage in accordance with operation frequency of a liquid crystal panel to the liquid crystal panel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
