Configurable multi-view display device

Abstract

A configurable multi-view display device (100) , f or providing 2D mode or 3D mode with a variable number of views (5 views, 9 views...) / comprising: a structure (104) of light modulating elememts (105-108) , for providing image data and a predetermined pattern of light 8 (either alternately or simultaneously using an invisible wavelength) , an optical directory means (110) , comprising a liquidcrystal layer having a lens action being spatially controllable according to a pattern of potential differences applied to it, an optical configuration means (118-122) for applying said pattern of potential differences, having photoconductive properties (photoconductive layer 120, active matrix plate of photoconductive elements 602) , wherein said predetermined pattern of light determines the impedances within the optical configuration means due to said photoconductive properties, thereby determining said pattern of potential differences, thereby determining said lens action, and thereby determining the actual view configuration, so that the axtual view configuration of the multi-view display device is set by means of the structure of loight modulating elements .

Description

technical field [0001] The present invention relates to a configurable multi-viewpoint display device, comprising: [0002] - a light modulating element structure located in the first plane for providing the respective light beams to; [0003] - optical guiding means located in a second plane substantially parallel to the first plane for directing the respective light beams in one or more predetermined directions relative to the first plane according to the actual viewpoint configuration of the multi-viewpoint display device. Background technique [0004] Realistic three-dimensional (3D) display devices have been a dream for many years since the introduction of display devices. A number of principles have been investigated that could lead to such display devices. Some principles try to create realistic 3D objects in a certain space. For example, in a display device as disclosed in the article "Solid-state Multi-planar Volumetric Display" by A. Sullivan in proceedings of S...

AI Technical Summary

Problems solved by technology

The disadvantage is that the number of windows (i.e. parts with a different view mode compared to the rest of the display device) that can be obtained with a passive matrix approach is limited

There are also restrictions regarding the shape of these parts

For example, it is difficult to create a large circular area in 2D viewpoint mode while other parts are in 3D viewpoint mode

Furthermore, it is not possible to switch from a first view configuration with eg nine views to a second view configuration with eg eight views
