Stacked Transparent Display Layers for Glass-Free 3D
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D displays require viewers to wear glasses to separate interlaced images, making them impractical for uses outside of entertainment and lacking a true 3D representation.
Innovation Solution
A method and apparatus using stacked transparent display layers, where a processor determines the 3D effect and presents data to each layer, creating a real 3D representation by rendering graphical entities on multiple layers based on spatial relationships and range data, allowing for a glass-free 3D experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3D displays use interlaced images with glasses, then depth perception is achieved, but device complexity and impracticality increase for non-entertainment uses
Solution Approach 1:
The display is segmented into multiple transparent layers stacked in the Z-direction, with each layer displaying a portion of the 3D object at a different depth position. This segmentation eliminates the need for glasses by physically separating the image components in space, allowing direct viewing of the 3D effect.
Solution Approach 2:
The invention transitions from 2D interlaced displays to 3D stacked layers by adding the Z-dimension (depth) as a display dimension. Each layer is positioned at a different Z-coordinate, creating true spatial depth rather than simulating it through interlacing techniques.
2Reliability
If stacked transparent layers are used for 3D display, then true 3D representation is achieved, but manufacturing complexity increases
Solution Approach 1:
Multiple transparent display layers are nested stacked one on top of another in the Z-direction, with each layer containing a portion of the 3D object. This nesting approach allows compact integration of multiple display elements while maintaining their individual functionality and transparency.
3Measurement precision
If multiple display layers are stacked to create 3D effect, then resolution and detail increase, but device complexity increases
Solution Approach 1:
The 3D object is segmented and distributed across multiple transparent layers, with each layer rendering a specific depth portion. This segmentation enables high-resolution 3D representation by allocating detailed features to appropriate depth layers, improving overall measurement precision and visual fidelity.

AI summary
The invention concerns an apparatus comprising a plurality of display panels and a processor. The plurality of display panels may be arranged as individual display layers in a stacked formation, each configured to display video output. The processor may be configured to determine a three dimensional effect of a graphical entity and present data for the video output to each of the display panels in response to the three dimensional effect. Each of the display panels may be transparent at locations without the video output. Determining the three dimensional effect may comprise determining a portion of the three dimensional effect for the video output to display on each of the individual display layers. The video output combined on the stacked formation may comprise a real three dimensional representation of the graphical entity.
