Abstract:
1. A driving apparatus for driving a display optical device, said display optical device having (a) a variable-optical-characteristic layer with an optical characteristic which varies in accordance with a strength of an electrical field, (b) a plurality of pixel electrodes provided at respective pixel-electrode positions, and (c) a facing electrode having a position so as to face said pixel-electrode positions and so as to sandwich said variable-optical-characteristic layer, said driving apparatus comprising: a driving section configured to vary said optical characteristic of said variable-optical-characteristic layer in accordance with a moving-image signal by application of a voltage signal representing said moving-image signal between said pixel electrodes and said facing electrode; and an inversion control section configured to invert a polarity of said voltage signal applied between said pixel electrodes and said facing electrode, said inversion control section also configured to shift a phase of a polarity-switching control signal every phase change period, wherein,
