3D Mural Display Using Wavelength Multiplex Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D projection technologies, particularly those using wavelength multiplex visualization, are expensive and limited to large-scale theatrical experiences, making it impractical to provide 3D imagery in smaller spaces or locations outside conventional theater settings, such as amusement park rides, where viewers wear 3D stereo glasses but no projectors are present.
Innovation Solution
A 3D display system that uses flat or nearly flat murals with lenticular panels and strategically positioned light sources emitting specific wavelength bands to create 3D imagery for viewers wearing wavelength multiplex visualization glasses, eliminating the need for expensive 3D projectors and allowing 3D effects in areas without projector coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wavelength multiplex visualization (WMV) technology is used to provide 3D imagery, then 3D effects can be achieved for viewers wearing 3D glasses, but the system becomes expensive and limited to large-scale theatrical settings
Solution Approach 1:
The patent uses flat or nearly flat murals as simplified copies of traditional 3D projection systems. These murals contain embedded wavelength multiplex visualization elements that replicate the 3D effect without requiring expensive projectors. The mural itself becomes a passive 3D display medium that can be viewed with WMV glasses, eliminating the need for active projection equipment while maintaining 3D imagery quality.
Solution Approach 2:
The patent replaces expensive, complex projector systems with inexpensive mural elements. The murals are static, non-projecting surfaces that can be manufactured at low cost and deployed in various settings. This disposable-like approach allows widespread distribution of 3D viewing experiences without investing in costly projector infrastructure.
2Reliability
If expensive 3D projectors are used to provide 3D imagery, then full-color full-stereo 3D effects can be achieved, but the system cannot be deployed in areas without projector coverage such as amusement park ride queues
Solution Approach 1:
The patent extracts the essential 3D functionality from the projector system and embeds it directly into the mural itself. By removing the need for external projection equipment, the 3D effect becomes an inherent property of the mural that can be placed anywhere viewers wear WMV glasses, dramatically increasing deployment flexibility to locations like amusement park queues, waiting areas, and other non-theater settings.
Solution Approach 2:
The mural-based system serves multiple functions: it provides 3D imagery without requiring projectors, can be installed in diverse locations, and works with standard WMV glasses. This universal approach allows the same mural technology to be deployed in theaters, amusement parks, museums, and other venues, making the system highly adaptable to different environments and use cases.
3Loss of information
If traditional projection systems are used, then 3D content can be displayed, but the system requires expensive projectors and is not cost-effective for smaller spaces
Solution Approach 1:
The patent creates passive mural copies that encode 3D content directly in their structure. These murals replicate the visual information needed for 3D viewing without requiring active projection equipment. The mural itself becomes the information carrier, eliminating the need for expensive projectors while maintaining full-color full-stereo 3D content delivery capability.

Data Source
AI summary
A display system creating three dimensional (3D) imagery for a viewer in a viewing space wearing 3D stereo glasses. The 3D stereo glasses have first and second lens passing colored light in first and second ranges of wavelengths. The display system includes a 3D mural element with a display surface facing the viewing space and a light receiving surface opposite the display surface. The display system includes a first wavelength multiplex visualization (WMV) light source outputting a first light stream onto the light receiving surface, and the first light stream has a wavelength in the first range of wavelengths. The display system includes a second WMV light source outputting a second light stream onto the light receiving surface, and the second light stream has a wavelength in the second range of wavelengths. WMV light sources may be directed onto 3D surfaces and props in the viewing space providing 3D effect.
