Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image display devices struggle to provide a wide range of viewing angles while maintaining a consistent display viewing angle, limiting the three-dimensional effect for viewers at different positions.
Innovation Solution
A display device and method that utilizes a display panel with sub-pixels and lenses to allocate and project multiple view images, allowing for various viewing angles by mapping image data according to different modes, including normal, low-resolution, and high-resolution 3D modes, to create a light field image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stereoscopic image display device uses a fixed display viewing angle determined by the lens, then the image quality is consistent, but the viewing angle range is limited
Solution Approach 1:
The patent divides the display into multiple sub-pixels (first to N-th sub-pixels) and allocates different view images to different sub-pixel groups. By segmenting the display area and using multiple lenses corresponding to different sub-pixel groups, the system can provide different display viewing angles for different regions while maintaining consistent image quality within each segment. This allows viewers at different positions to experience optimal image quality.
Solution Approach 2:
The patent dynamically allocates view images to sub-pixels based on the viewing angle mode. In normal mode, it allocates first to M-th view images to first to N-th sub-pixels; in wide viewing angle mode, it adjusts the allocation to provide broader coverage. This dynamic allocation allows the display device to adapt to different viewing scenarios, expanding the effective viewing angle range while maintaining image quality consistency for each viewer position.
2Adaptability or versatility
If multiple view images are allocated to limited sub-pixels, then the viewing angle coverage increases, but the resolution may decrease
Solution Approach 1:
The patent segments the view images and sub-pixels into multiple groups. It allocates specific view images (first to M-th) to specific sub-pixel groups (first to N-th) in a structured manner, ensuring that each sub-pixel group receives appropriate image data for its designated viewing angle. This segmentation allows multiple views to be displayed simultaneously without compromising the resolution for each individual view.
Solution Approach 2:
The patent applies different allocation strategies to different sub-pixel groups based on their positions and corresponding viewing angles. Each sub-pixel group is optimized for its specific viewing angle range, maintaining high resolution for viewers in that range. This local optimization ensures that resolution is preserved for each viewing zone while collectively covering a broader angular range.
3Adaptability or versatility
If the display device provides wide viewing angle coverage, then more viewers can see the image, but the three-dimensional effect may be reduced for individual viewers
Solution Approach 1:
The patent segments the viewing area into multiple zones, each served by specific sub-pixel groups and lenses. This ensures that each viewer position receives dedicated image data optimized for that angle, maintaining strong three-dimensional effects even as the number of supported viewers increases. Each segment operates independently to preserve stereo quality.
Solution Approach 2:
The patent creates a multi-functional display system where the same display device can serve multiple viewing angles and multiple viewers simultaneously. By making the system universal across different viewing scenarios through configurable view image allocation, it maintains reliable three-dimensional effects for each viewer while accommodating a broader audience.
