Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices that generate 3D images without glasses, such as lenticular and barrier types, face limitations in providing a consistent 3D effect at various viewpoints due to fixed lens orientations, leading to suboptimal performance in displaying 3D images at different angles.
Innovation Solution
A lens panel comprising a first and second lens array with variable lenses, where the curvature changes with fluid injection or discharge, allowing for adaptive refraction and improved 3D image perception at multiple viewpoints, along with a pressurizing device to control fluid flow and lens curvature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed lens orientations are used in glass-free 3D display devices, then the device structure is simple, but the 3D effect is inconsistent at various viewpoints
Solution Approach 1:
The patent applies the dynamics principle by making the lens array configurable between different states. Specifically, the lens array can be switched between a first configuration (with lenses extending in a first direction for 3D display at first viewpoint) and a second configuration (with lenses extending in a second direction for 3D display at second viewpoint). This dynamic reconfigurability allows the device to adapt to different viewing requirements, resolving the contradiction between maintaining simple structure and achieving consistent 3D effect at various viewpoints.
Solution Approach 2:
The patent implements parameter changes by modifying the orientation and direction of the lens array. The lens array's extending direction can be changed from a first direction to a second direction, which corresponds to changing the optical parameters of the display system. This parameter change enables the device to optimize 3D image quality for different viewpoints without requiring completely different hardware structures.
2Reliability
If variable lenses with fluid injection are used, then 3D image quality at multiple viewpoints is improved, but the device complexity increases due to additional fluid control mechanisms
Solution Approach 1:
The patent applies the universality principle by designing a single lens array that can serve multiple functions through reconfiguration. The same lens array structure is used for displaying 3D images at different viewpoints by changing its orientation, rather than requiring separate lens arrays for each viewpoint. This multi-functional design improves 3D image quality across multiple viewpoints while avoiding the need for multiple identical systems, thereby managing complexity more efficiently.
Solution Approach 2:
The variable lenses with fluid injection capability enable dynamic adjustment of lens properties. The fluid injection mechanism allows the lenses to change their curvature and focal properties, which is essential for maintaining high 3D image quality across different viewpoints and configurations. This dynamic capability is integrated into a unified control system that manages both the lens configuration and fluid injection, optimizing the balance between performance and complexity.
3Adaptability or versatility
If lens curvature is dynamically adjusted, then viewing angle flexibility is enhanced, but the control system complexity increases
Solution Approach 1:
The patent implements parameter changes by dynamically adjusting the curvature of the lenses through fluid injection and pressurization. The lens curvature parameter can be modified to optimize the display for different viewing angles and configurations. This parameter adjustment is controlled through an integrated pressurizing device that can selectively pressurize different regions of the lens array, enabling flexible adaptation to various viewing requirements while maintaining a unified control architecture.
