Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D image display technologies, such as parallax barrier and lenticular displays, face challenges in adapting to different orientations (landscape and portrait modes) without significant redesign, limiting their ability to provide high-quality 3D images across various viewing angles.
Innovation Solution
An optical layer with slanted optical components, including parallax barriers and lenticular lenses, is designed to selectively transmit or refract light, with specific angle and spacing configurations (θ and l) that satisfy Equations 1 and 2, allowing for optimal viewing angles in both landscape and portrait modes, ensuring a minimum of 3 degrees and a maximum proportional to the display panel size.

Engineering Contradiction Analysis
1Measurement precision
If optical components are configured for a specific orientation (landscape or portrait mode), then the viewing angle quality is optimized for that mode, but the display device cannot provide high-quality 3D images in the other orientation without redesign
Solution Approach 1:
The optical layer is designed with slanted optical components that can simultaneously provide optimized viewing angles for both landscape and portrait modes. The slant angle θ and spacing l are specifically calculated to satisfy viewing angle requirements in both orientations, making the optical layer universal across different display orientations without requiring separate designs for each mode.
Solution Approach 2:
The patent applies parameter changes by optimizing the slant angle θ and spacing l of optical components based on mathematical relationships involving viewing angles in both landscape (VAL) and portrait (VAP) modes. By adjusting these parameters according to the equations provided, the optical layer adapts to provide high-quality 3D imaging across different orientations.
2Measurement precision
If optical components are added to achieve wider viewing angles, then the viewing angle range is improved, but the device thickness and manufacturing complexity increase
Solution Approach 1:
The patent optimizes the viewing angle range by adjusting the slant angle θ and spacing l parameters of the optical components. The mathematical relationships establish that tan θ = a = l/(2g×tan(VAP/2)), where g is the distance between the display panel and optical layer. By carefully selecting these parameters, the patent achieves wide viewing angles in both landscape and portrait modes while avoiding unnecessary increases in device thickness or manufacturing complexity.
