Three-dimensional image display device, method for displaying three-dimensional image, and structure of three-dimensional image data

Abstract

A three-dimensional image display device includes a display section having pixels arranged in a matrix and each includes three color component sub-pixels arranged in vertical stripes, and a light beam control element installed opposite the display section and having optical apertures arranged in a substantially horizontal direction and extending linearly in a direction inclined at an angle atan (1 / n) (n=4 or 5) to a direction of pixel columns. The average value of the horizontal pitch of element images displayed in the display section is specified to be equal to or greater than natural number m times as large as a pixel horizontal pitch (m G02B 27 / 22 H04N 13 / 00 22 26 2 2008 / 3 / 14 101276061 2008 / 10 / 1 000000000 Toshiba KK Japan Saishu Michio Fukushima Rieko Taira Kazuki Hirayama Yuzo huangrui wangyang 72002 NTD Patent & Trademark Agency Ltd.

Description

technical background [0001] The invention relates to a three-dimensional image display device and a method for displaying a three-dimensional image. Background technique [0002] Various schemes of three-dimensional image display devices (ie, three-dimensional displays) for displaying moving images have been disclosed. In recent years, demand for planar-type solutions that do not require special glasses or the like has grown remarkably. As this type of three-dimensional moving image display device, a proposal utilizing the principle of holography has been disclosed. With this scheme, it is difficult to realize full-color moving images. Another known solution is to arrange a light beam control element directly in front of the display panel used as a three-dimensional image display device, which can control the light beam directed from the display panel to the observer. This solution uses a direct-view display device or a projection-type liquid crystal display device or a p...

Problems solved by technology

However, the vertical resolution of the former is not lower than that of the latter

As a result, the overall vertical and horizontal resolution is unbalanced, reducing image quality

Another problem is that if the color settings of the 3D image do not form horizontal bars, the color distribution is not uniform

[0009] As mentioned above, the problem with the conventional three-dimensional image display device with the beam control element arranged obliquely is that the vertical lines appear jagged, which reduces the display quality of the characters; The horizontal resolution is reduced, which reduces the image display quality
