Solution Overview
Problem
Current 3D display technologies, such as parallax type and integral imaging, suffer from rapid motion parallax fluctuations and discomfort when viewers change locations, leading to unnatural stereoscopic impressions due to limited view-zones and optical design limitations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parallax type 3D display concentrates light to form view-zones, then stereoscopic impression is obtained at designed view points, but image quality fluctuates dramatically and motion parallax flips severely when viewer changes location
Solution Approach 1:
The patent segments the display into multiple stereoscopic display units, each providing different diverge images. This segmentation allows different regions of the display to provide optimized images for different viewing directions, thereby improving both image quality and adaptability to viewer location changes.
Solution Approach 2:
The patent employs dynamic image guiding plates with periodically arranged optical structures that can guide image beams to different directions. This dynamic capability allows the system to adapt to viewer location changes by redirecting appropriate image beams, maintaining stable stereoscopic visual effect across multiple viewing locations.
2Stability of the object's composition
If integral imaging 3D display uses parallel light design, then stable stereoscopic visual effect is achieved, but the number of view-zones is limited and motion parallax smoothness is restricted
Solution Approach 1:
The patent merges the advantages of both parallax type and integral imaging approaches by combining parallel light design with multiple diverge images. The system maintains the stability of parallel light while increasing the number of available view-zones through multiple stereoscopic display units, thereby improving motion parallax smoothness.
Solution Approach 2:
The patent extends the traditional 2D display into 3D space by arranging multiple stereoscopic display units and using optical structures to guide beams in different directions. This dimensional extension creates multiple view-zones and improves motion parallax update frequency while maintaining image stability.
3Adaptability or versatility
If display apparatus provides multiple diverge images with more view-zones, then viewing adaptability improves, but device complexity increases
Solution Approach 1:
The patent designs stereoscopic display units that can function universally for multiple viewing directions. Each display unit provides diverge images that can be guided to different directions by the optical structures, allowing the system to achieve multiple view-zones without proportionally increasing the number of physical display units.
Solution Approach 2:
The patent introduces image guiding plates with optical structures as intermediaries between the display units and the viewer. These optical structures act as mediators that can redirect image beams to different directions, enabling the system to provide multiple view-zones without directly increasing the number of display units, thereby controlling device complexity.
