Patent ID: 7786953

Claim:
A three-dimensional image display apparatus comprising: a display module having a display surface on which pixels are arranged in rows and columns; a display driver configured to generate field image signals to the display module, the display surface being scanned along the column in accordance with each of the field image signals to display elemental images on the pixels, respectively, and form a field image on the display surface, the field image being sequentially rewritten to form a frame image; a lens array installed in front of the display module and having a plurality of lenses which include optical apertures linearly extended along the column and which are arranged along the row; a shutter device installed on a convex surface side of the lens array and including a plurality of shutter elements which are extended substantially along the column and arranged along the row or in rows and columns to have a predetermined relationship with the plurality of lenses; and a shutter driver configured to drive the shutter device to open a group of the shutter elements and close another group of the shutter elements, simultaneously, and display each of the field image from the shutter device, the group of the shutter elements transmitting light beams from the elemental images through the lenses, while the another group of the closed shutter elements blocks the light beams from the elemental images through the lenses, wherein the shutter driver closes a series of shutter elements which are arranged along the row and corresponds to the row or rows of pixels to be rewritten and then opens the closed shutter elements in synchronization with the rewriting of the row or rows of pixels, the shutter driver sequentially changes the group of the opened shutter elements in synchronization with the scanning of the display surface, and the elemental images are sequentially projected on an observing zone from the display apparatus to form the three-dimensional image.
