Problems solved by technology

In the 2-eye method, this problem does not occur because the field of view is limited to the front of the screen, but it occurs in the IP method and the multi-eye method, which have a wide field of view and a large number of parallaxes.

Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] FIG. 1 shows a stereoscopic image display device according to an embodiment of the present invention. FIG. 1 is a cross-sectional view in the left-right direction of the stereoscopic image display device 1 of the present embodiment. The element image display unit 10 is a liquid crystal panel, with a pixel surface between two glass substrates 11a and 11b, and polarizing plates 12a and 12b are provided outside the glass substrates 11a and 11b. The pixels of the liquid crystal panel 10 are divided into sub-pixels having three color components (for example, color components of R (red), G (green), and B (blue)) along the left-right direction. The light control element 20 is a lenticular lens sheet. The pixel group corresponding to one lens of the lenticular lens sheet 20 is one element image 15. The element image 15 is 6 sub-pixel rows in FIG. 1. The light from the elemen...

Abstract

This invention provides a stereoscopic image display apparatus and a stereoscopic image display method capable of preventing a luminance difference from being caused between left and right eyes irrespective of the observation position even if the viewing zone is wide and the number of parallaxes is large. The stereoscopic image display apparatus includes: a display unit (10) including pixels arranged in a matrix form in a longitudinal direction and a lateral direction; an optical plate (20) installed so as to be opposed to the display unit and having linear optical openings prolonged in a longitudinal direction and arranged in a lateral direction; and a luminance compensation processing unit which, for each of elemental images associated with the optical openings, sets a brightness of an image displayed on a pixel located in a center of the elemental image smaller than a brightness of an image displayed on a pixel located in each of boundaries of the elemental image.

Description

Technical field [0001] The invention relates to a stereoscopic image display device and a stereoscopic image display method. Background technique [0002] Various methods are known in stereoscopic image display devices capable of displaying moving images, so-called three-dimensional displays. In recent years, the requirements for a tablet type and a method that does not require dedicated eyes, etc. have become particularly high. In this type of stereoscopic moving image display device, it is difficult to realize full-color moving images using the holographic principle, but it can be easily realized in direct-view or projection type liquid crystal display devices, plasma display devices, etc. The fixed display panel (display device) is provided with a light control element that controls the light from the display panel and faces the observer. [0003] The light control element is also generally called a parallax barrier, which controls the light so that different images depending ...
