Stereoscopic Display Oblique View via Micro-Structure Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic displays fail to provide a natural oblique angle of view and cannot display stereo images as if they are floating in mid-air, limiting their usability in situations like aviation and medical training where an oblique view is natural to the user.
Innovation Solution
A stereoscopic display comprising a flat-panel display with a lens array layer and a micro-structure layer, where the lens array layer adjusts the light field and the micro-structure layer modulates light direction to refract it at an oblique angle, allowing the stereo image to be viewed from a natural angle and creating a vivid floating effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stereoscopic displays are placed horizontally, then the display can be positioned for situations like aviation terrain models and building models, but the user cannot view the image from a natural oblique angle
Solution Approach 1:
The patent introduces a micro-structure layer with microlens arrays that manipulate light in the vertical dimension, enabling the image to be projected at an oblique angle rather than strictly perpendicular to the display plane. This dimensional change in light projection allows users to view the stereoscopic image from a natural oblique angle when the display is placed horizontally.
2Ease of manufacture
If conventional stereoscopic displays provide visual stimuli in one direction, then the display structure remains simple, but the image cannot create a vivid floating sensation in mid-air
Solution Approach 1:
The patent divides the optical system into multiple functional layers: a display panel layer, a microlens array layer, and a micro-structure layer. Each layer performs a specific function in manipulating light to create the floating effect. This segmentation allows the complex optical manipulation needed for the floating effect while maintaining relatively simple individual components that can be manufactured separately and assembled.
3Reliability
If conventional stereoscopic displays use binocular fusion, then the stereo image can be displayed, but the image is unviewable from any angle other than the front
Solution Approach 1:
The patent introduces a micro-structure layer with microlens arrays as an intermediary between the display panel and the viewer's eyes. This intermediary component manipulates the light field to redirect stereoscopic images at oblique angles while maintaining the binocular fusion effect. The microlens arrays act as optical mediators that preserve stereo image quality while expanding the viewing angle range.
