Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autostereoscopic display technologies have fixed system parameters, such as grating width, which limit the range of parallax support, leading to image quality issues like interference and ghosting, and fail to dynamically adjust to varying viewer positions or distances.
Innovation Solution
A 3D display system with an optical device having electric-signal-controllable parameters, such as adjustable grating width and length, that separates image sets into predetermined viewing directions using a dynamic lens or parallax barrier, controlled by a processor to optimize image quality and viewer comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a small fixed grating width is used in conventional autostereoscopic display, then the clarity of 3D images is maintained, but the range of parallax support is limited
Solution Approach 1:
The patent implements a dynamically adjustable grating width system where the grating width can be changed based on viewing conditions. The system includes a controller that adjusts the grating width parameter in real-time to match different viewer positions and distances, transforming the static optical system into a dynamic one that adapts to varying requirements.
Solution Approach 2:
The patent changes the optical parameters of the display system by making the grating width adjustable. Different grating width parameters are selected based on the required parallax range and viewing distance, allowing the system to optimize between image clarity and parallax support by selecting appropriate parameter values.
2Adaptability or versatility
If a large grating width is used in conventional autostereoscopic display, then the range of parallax support is increased, but the clarity of 3D images is reduced
Solution Approach 1:
The system dynamically adjusts grating width based on real-time detection of viewer position and distance. When large parallax support is needed, the system increases grating width; when image clarity is prioritized, it decreases grating width. This dynamic adjustment resolves the trade-off by making the system adaptive rather than static.
Solution Approach 2:
The patent employs parameter changes by selecting appropriate grating width values based on operating conditions. The controller modifies the grating width parameter to match the required balance between parallax range and image clarity, allowing optimal performance across different viewing scenarios.
3Device complexity
If fixed system parameters are used in conventional autostereoscopic display, then the device complexity is reduced, but the adaptability to varying viewer positions and distances is limited
Solution Approach 1:
The patent incorporates a feedback mechanism where the system detects viewer position and distance, processes this information, and adjusts the grating width parameter accordingly. This closed-loop control enables the system to adapt to varying viewing conditions while maintaining manageable complexity through automated control.
Solution Approach 2:
The patent replaces fixed mechanical optical structures with an electrically controllable system. Instead of physically changing the grating structure, the system uses electrical signals to adjust optical parameters, reducing mechanical complexity while enhancing adaptability.
4Adaptability or versatility
If dynamic parallax strips are generated based on head movement tracking, then the adaptability to viewer movement is improved, but the device complexity and limitations to specific system configurations increase
Solution Approach 1:
The patent creates a universal solution that can be applied to different display system configurations. The grating width adjustment mechanism serves multiple functions: supporting different viewing distances, accommodating various parallax requirements, and adapting to viewer movement. This multi-functionality reduces the need for specialized configurations for each application.
