Title: Apparatus displaying three-dimensional image

Abstract: In a three-dimensional image display apparatus in which a lenticular plate and shutter device are arranged in front of a display module, one frame image is displayed using n field images. To display each field image, a shutter device is driven to substantially simultaneously open a group of shutter elements for every n lenses along a horizontal direction. Thus, light beams are transmitted from lenses through the shutter elements to an observing zone. The group of the opened shutter elements is sequentially changed in response to n switchings of the field. The switching of shutter elements is synchronized with the pixels on the display surface sequentially rewritten from top to bottom by linear sequential driving during the switching of the field. The elemental image is projected on the viewing zone via the lenses and the shutter elements.
