Light Path Adjuster for Seamless 3D Display Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integral imaging displays face challenges in concealing connecting joints between display panels, which can obstruct the viewer's perception of a seamless three-dimensional image, and in correcting image deformations caused by these joints.
Innovation Solution
The use of light path adjusters with a lens array and a joint removal structure, such as a wedge-shaped groove or Fresnel lens structure, to refract beams and conceal the connecting joints, combined with a transparent optical layer to adjust beam paths, and an image processing system to correct image deformations based on an estimated image generating model.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are used to form a large display area, then the display area is improved, but the connecting joints between panels become visible and obstruct the seamless image perception
Solution Approach 1:
The patent extracts the harmful visual effect of connecting joints by introducing a light path adjuster that specifically targets and refracts light from the joint regions. The joint removal structure within the light path adjuster is positioned to correspond to the connecting joint location, selectively processing light from this specific area to eliminate its visibility while preserving the overall display area advantage of using multiple panels.
Solution Approach 2:
The light path adjuster serves as an intermediary component positioned between the display panels and the viewer's eye. It includes a joint removal structure that acts as a mediator to refract and redirect light from the connecting joint, preventing it from reaching the viewer's eye directly. This intermediary device enables multiple display panels to be used while concealing the joints through optical intervention.
2Object-affected harmful factors
If a light path adjuster is added to conceal connecting joints, then the joint concealment is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated component - the light path adjuster. It combines the joint removal structure for concealing connecting joints with the lens array for transferring light to different eyes, and integrates the transparent optical layer for adjusting beam paths. By consolidating these functions into one assembly that can be positioned on the display panel, the patent achieves effective joint concealment while minimizing the increase in device complexity compared to adding separate components for each function.
3Object-affected harmful factors
If the light path adjuster is positioned on the display panel, then the joint concealment effect is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by designing the joint removal structure with specific optical properties only in the region corresponding to the connecting joint, while other areas of the light path adjuster maintain standard optical characteristics. The wedge-shaped or Fresnel lens structure is localized to the joint region, allowing precise control of light paths from the joint area without requiring the entire light path adjuster to meet extremely high manufacturing precision standards, thus balancing joint concealment effectiveness with manufacturability.
