Solution Overview
Problem
Conventional three dimensional display apparatuses often suffer from the moiré pattern phenomenon, which degrades display quality.
Innovation Solution
A three dimensional display apparatus featuring a fly-eye lens array with square lens units, where the pitch of the lens units is between 1 mm and 1.5 mm, the focal length is between 2.2 mm and 3.5 mm, and specific angles between the lens units and the display panel are optimized to prevent the moiré pattern, ensuring improved display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional three dimensional display apparatus uses traditional lens array configuration, then three dimensional display function is achieved, but moiré pattern phenomenon occurs degrading display quality
Solution Approach 1:
The patent applies asymmetry by using rectangular lens units instead of traditional circular or square lenses, with specific width and length dimensions that create an asymmetric optical path. This asymmetric geometry disrupts the periodic interference patterns that cause moiré effects, while still maintaining the ability to perform optical convergence for 3D display functionality.
Solution Approach 2:
The patent changes key parameters of the lens array system: the lens pitch is set to specific ranges (1.0-1.5mm, 2.2-3.5mm focal length), and the rectangular lens dimensions are optimized within specific ranges. These parameter adjustments are designed to eliminate moiré patterns while preserving the 3D display capability.
2Ease of manufacture
If lens units are made with specific pitch and focal length ranges, then moiré pattern is eliminated, but device complexity increases
Solution Approach 1:
The patent establishes specific parameter ranges for lens pitch (1.0-1.5mm), focal length (2.2-3.5mm), and lens dimensions that optimize the system to eliminate moiré patterns. By defining these parameters within specific ranges rather than fixed values, the patent balances performance optimization with manufacturing flexibility, reducing overall device complexity.
