Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 3D image display apparatus adjusts pixels to display left-eye or right-eye signal according to head position, then the display can adapt to user movement, but cross-talk occurs when one eye receives both left-eye and right-eye signals simultaneously
Solution Approach 1:
The patent segments the display into multiple sub-pixels (at least six sub-pixels per pixel) and assigns different sub-pixels to different eyes. By calculating position information for each sub-pixel and adjusting their individual intensities, the system directs specific sub-pixel signals to specific eyes, preventing cross-talk while maintaining adaptability to head position changes.
Solution Approach 2:
The patent applies local quality by making different parts of the display (sub-pixels) have different functions and properties. Each sub-pixel's intensity is independently calculated and adjusted based on its specific position and the user's head position, allowing precise control over which eye receives which signal, thereby eliminating cross-talk while preserving adaptability.
2Stability of the object's composition
If conventional 3D image display apparatus uses at least six sub-pixels to avoid image motion juddering, then image stability is improved, but display resolution is reduced
Solution Approach 1:
The patent implements dynamics by continuously tracking the user's head position and dynamically adjusting the intensity and position information of sub-pixels in real-time. This dynamic adjustment allows the system to maintain image stability across different head positions without requiring a fixed, resolution-reducing pixel configuration, as the sub-pixel intensities are adaptively optimized for each viewing position.
Solution Approach 2:
The patent changes parameters by adjusting the intensity information of individual sub-pixels based on calculated position information. By varying the intensity parameters of sub-pixels dynamically rather than using a static pixel configuration, the system achieves image stability without sacrificing display resolution, as the full resolution of the display panel is maintained while sub-pixel intensities are modulated to prevent juddering.
