Solution Overview
Problem
Autostereoscopic 3D displays face challenges in maintaining image quality and reducing computational complexity as the number of views or directions increases, leading to degraded resolution and increased operational complexity.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of views or directions is increased to broaden the viewing area, then the viewing area is improved, but the image quality deteriorates due to crosstalk between views and resolution decreases
Solution Approach 1:
The patent applies local quality by directing different numbers of light beams to different spatial locations. Specifically, a first number of light beams are directed to a first location while a second number of light beams are directed to a second location, where the first number is greater than the second number. This allows the system to provide broader viewing areas in certain directions while maintaining higher image quality in other directions, optimizing the trade-off locally rather than uniformly across all viewing angles.
2Loss of information
If the number of views or directions is increased to express more information, then the information expression is improved, but the computational complexity increases
Solution Approach 1:
The patent implements local quality in information expression by allocating different amounts of information to different locations. The system expresses a first amount of information at a first location and a second amount of information at a second location, where the first amount exceeds the second amount. This selective information allocation reduces the overall computational burden while ensuring that critical viewing positions receive sufficient information, thereby managing the trade-off between information completeness and computational complexity.
3Ease of operation
If eye tracking is used to restrict image display to specific viewer locations, then the operational complexity is reduced, but the adaptability to multiple viewer positions decreases
Solution Approach 1:
The patent applies dynamics by making the light beam configuration adaptive to viewer positions. The system dynamically directs different numbers of light beams to different locations based on where viewers are positioned. This allows the display to maintain low operational complexity for each specific viewer configuration while adapting to accommodate multiple different viewer positions, effectively resolving the contradiction between operational simplicity and versatility.
