Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 2D multiplexed technology (spatial or time multiplexing) is used to generate left-eye and right-eye images, then stereoscopic perception is achieved, but image resolution is reduced
Solution Approach 1:
The display system is segmented into multiple independent display panels (first display panel, second display panel, third display panel) positioned at different depths. Each panel displays images for both left and right eyes simultaneously without multiplexing, thereby maintaining full image resolution while achieving stereoscopic perception through spatial separation of display elements.
Solution Approach 2:
The invention transitions from 2D multiplexed display to 3D spatially-separated display. By adding the depth dimension with multiple display panels at different positions (first display panel at first position, second display panel at second position, third display panel at third position), the system achieves stereoscopic perception without compromising 2D image resolution on each panel.
2Adaptability or versatility
If volumetric technology with rapidly rotated circular plate is used, then stereoscopic image construction is achieved, but rotation speed variation causes blur and reduces image quality
Solution Approach 1:
The invention replaces the mechanical rotation system (rapidly rotated circular plate) with a static multi-panel display system. The first display panel, second display panel, and third display panel are positioned at fixed locations without any moving parts. This eliminates rotation speed variation and its associated image blur, while still achieving stereoscopic image construction through spatial separation and selective image display to left and right eyes.
3Manufacturing precision
If holographic technology with acousto-optic modulator is used, then stereoscopic image recording is achieved, but the system becomes complicated, costly, and the image size is limited by crystal grain size
Solution Approach 1:
The invention extracts and eliminates the complex acousto-optic modulation system from the display architecture. Instead of using red, green, and blue laser beams passing through an acousto-optic modulator to generate phase grating information, the system directly displays stereoscopic images on multiple display panels. This removes the acousto-optic modulator, scanning mirror, and hologram recording requirements, significantly simplifying the system while maintaining stereoscopic image capability.
Solution Approach 2:
The invention uses direct digital image display on display panels instead of holographic recording. The first display panel displays first image information, the second display panel displays second image information, and the third display panel displays third image information, creating stereoscopic images through spatial arrangement rather than through holographic interference patterns. This approach allows flexible image sizes independent of crystal grain dimensions.
4Object-affected harmful factors
If transparent insulation layer with thickness of 0.5 cm to 10 cm is used in image-depth adjusting device, then optical interference is avoided, but device volume increases
Solution Approach 1:
The invention introduces an image-depth adjusting device positioned between the first display panel and second display panel. This intermediary device includes a transparent insulation layer with specific thickness (0.5 cm to 10 cm) that acts as an optical mediator to prevent interference between light from different display panels while maintaining a compact overall structure through optimized positioning and spacing.
