Deformation Unit for Dynamic Display Grating Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked-eye stereoscopic display devices have a fixed optimal viewing position, leading to ghosting and a compromised viewing experience when the viewer is not in the optimal position due to a fixed distance between the display panel and the grating structure.
Innovation Solution
A display module with a deformation unit, such as an electro-deformation or magneto-deformation unit, is introduced between the display panel and the grating structure, allowing the distance to be adjusted based on the viewer's position using a control circuit and sensors, ensuring optimal viewing by dynamically changing the thickness of the deformation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the display panel and the grating structure is fixed, then the structure is simple and stable, but the optimal viewing position is fixed causing image ghosting when the viewer is not in the optimal position
Solution Approach 1:
The patent introduces a deformation unit that can dynamically adjust the distance between the display panel and the grating structure. This transforms the previously fixed structure into a dynamic one, allowing the system to adapt to different viewing positions by changing the spacing between components, thereby eliminating image ghosting while maintaining structural feasibility.
Solution Approach 2:
The patent changes the physical parameter of the deformation unit (its thickness or deformation state) to adjust the distance between the display panel and the grating structure. By controlling the deformation degree of the deformation unit, the system can adapt to different viewing distances and positions, improving viewing adaptability without requiring complete structural redesign.
2Reliability
If a deformation unit is added to adjust the distance between the display panel and the grating structure, then the viewing experience is improved by eliminating image ghosting, but the device complexity increases
Solution Approach 1:
The patent employs a deformation unit that functions as a flexible component between the display panel and the grating structure. This flexible element can deform to adjust the spacing, providing the necessary adaptability for different viewing conditions while maintaining a relatively compact and integrated structure, thus balancing improved viewing quality with acceptable device complexity.
Solution Approach 2:
The deformation unit acts as an intermediary component between the display panel and the grating structure. It mediates the distance adjustment between these two components, allowing the system to achieve variable viewing positions without directly modifying the display panel or grating structure themselves, thereby isolating the complexity to a single adjustable component.
