Polarized Partition Set for Selective Display Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing polarized partitions that use polarization characteristics to shield image display screens do not effectively manage the visibility of all sections, as they either leave parts unshielded or compromise the design property of the partitioned space.
Innovation Solution
A polarized partition set comprising a first polarized partition with a polarizer and a retardation layer, and a second polarized partition, where the angle between the absorption axis of the polarizer and the slow axis of the retardation layer is specifically configured to achieve a chromatic polarization effect, allowing for selective shielding and design enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a partition with polarization characteristic is arranged to shield the display screen, then information security and privacy are improved, but the design property of the section deteriorates and other portions remain unshielded
Solution Approach 1:
The patent applies local quality by configuring different portions of the partition with different polarization characteristics. Specifically, a first polarized partition with a first polarizer and a second polarized partition with a second polarizer are arranged at different angles relative to the display screen's polarization direction. This creates localized shielding effects in different sections of the partition while maintaining design flexibility, allowing certain areas to shield the display screen effectively while other areas maintain aesthetic transparency.
2Reliability
If a partition with polarization characteristic is arranged to shield the display screen, then privacy is improved, but the visibility of other portions deteriorates
Solution Approach 1:
The patent implements local quality by creating zones with different polarization properties within the same partition structure. The first polarized partition shields the display screen area while the second polarized partition maintains visibility for other portions. This selective polarization approach ensures privacy protection where needed while preserving natural light transmission and visibility in areas where design aesthetics and openness are priorities.

Function Achieved in This Case
The combination of polarized partitions with strategically angled retardation layers and polarizers achieves effective shielding of desired sections while maintaining a visually appealing design, providing privacy and security by varying light absorption based on polarized states, resulting in colored or neutral light observation depending on the viewer's position.
Implementation Method 1
A partition having a polarization characteristic is arranged so as to be capable of absorbing linearly polarized light emitted from the display screen of the image display apparatus
Implementation Method 2
capable of absorbing linearly polarized light emitted from the display screen
