Patent ID: 8040310

Claim:
A method of driving a display apparatus comprising: providing an image display section for displaying a screen by controlling pixels in accordance with image data per vertical period, the pixels arranged in matrix, and providing a liquid crystal panel for switching between a 2D display and a 3D display of the apparatus so as to comprise an electrode pair sandwiching a liquid crystal layer therebetween, the image display section and the liquid crystal panel assembled together, so that the image display section includes a first liquid crystal layer and the liquid crystal panel includes a second liquid crystal layer spaced apart from the first liquid crystal layer; wherein the image display section and the liquid crystal panel are proximate to each other and are facing each other; and applying an inversion timing signal for inverting polarity of a voltage to be applied on the electrode pair included in the liquid crystal panel, said liquid crystal panel used for switching between a 2D display and a 3D display synchronized with the rising edge of the inversion timing signal, the inversion timing signal occurring once in two or more vertical periods of the image display section.
