Mirror-Panel 3D Display for Wide Viewing and Lower Cross-Talk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto-stereoscopic 3D display technologies face challenges in maintaining high resolution while providing a wide viewing range, often resulting in reduced image quality due to cross-talk and reduced brightness.
Innovation Solution
A display apparatus comprising a 3D display, an enhance display, and a mirror panel, controlled by a processor, which can switch between 3D and 2D modes, enhances image quality by rendering multiple image views with different viewpoints, compensating for cross-talk, and adjusting brightness and image quality based on mirror panel transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If auto-stereoscopic 3D display technologies are used to provide a wide viewing range, then viewing angle is improved, but image resolution deteriorates due to cross-talk
Solution Approach 1:
The display system is segmented into multiple independent displays (3D display and enhance display) that work together. The enhance display shows a single high-resolution image view while the 3D display provides multiple viewpoint images, allowing the system to maintain high resolution in the enhanced view while providing wide viewing range through the multifunctional setup.
Solution Approach 2:
The enhance display serves multiple functions: it displays high-resolution single-view images for users who need detailed viewing, and it provides source images that can be processed into multiview images for the 3D display. This multi-functionality allows the system to accommodate both high resolution requirements and wide viewing range requirements simultaneously.
2Area of moving object
If auto-stereoscopic 3D display technologies are used to provide a wide viewing range, then viewing angle is improved, but brightness deteriorates
Solution Approach 1:
The display system segments the viewing experience into two paths: one through the mirror panel for enhanced brightness viewing, and another directly for 3D viewing. Users can choose the mirror path to benefit from the enhanced display's brighter image, thus resolving the brightness limitation of conventional auto-stereoscopic displays.
Solution Approach 2:
The mirror panel acts as an intermediary that redirects light from the enhance display to the viewer's position. This intermediary mechanism allows the enhance display's brighter image to reach the viewer, compensating for the brightness loss that would otherwise occur in wide-viewing-angle auto-stereoscopic systems.
3Manufacturing precision
If multiple image views are rendered to improve 3D image quality, then cross-talk is reduced, but device complexity increases
Solution Approach 1:
The system merges the enhance display and 3D display into a coordinated multifunctional system. The processor combines images from the enhance display to generate multiview images for the 3D display, allowing complex image processing to be performed software-based rather than requiring complex hardware structures.
Solution Approach 2:
The patent replaces complex optical mechanical structures with software-based image processing. Instead of using complex optical elements to generate multiple views, the system uses a processor to render multiview images from single or multiple source images, significantly reducing mechanical complexity while maintaining image quality.
