Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current polarizers have limitations in enhancing the viewing angle performance, which affects the overall display quality of liquid crystal display devices.
Innovation Solution
A polarizer design incorporating a resin layer with whiskers, where the acute angle between the whisker's long-axis direction and the resin layer's bottom surface is optimized between 0° and 40°, and the whiskers are specifically structured with varying diameters and shapes to enhance light scattering and viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If whiskers are dispersed in film layers of the polarizer, then the viewing angle of the polarizer is enhanced, but the performance on the viewing angle is expected to be further improved
Solution Approach 1:
The patent changes the orientation angle parameter of whiskers relative to the resin layer bottom surface, specifying that the acute angle should be greater than 0° and less than or equal to 40°. This parameter optimization enhances light scattering performance in the horizontal direction, thereby improving viewing angle performance while maintaining polarizer functionality.
Solution Approach 2:
The patent uses a composite structure consisting of whiskers dispersed in a resin layer. The whiskers (inorganic particles) combined with the resin matrix create a composite material that provides both structural support and optimized light scattering properties, achieving enhanced viewing angle performance.
2Adaptability or versatility
If the acute angle between whisker long-axis and resin layer bottom surface is optimized, then light scattering control is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a range for the acute angle (greater than 0° and less than or equal to 40°) rather than a single precise value. This parameter range provides manufacturing flexibility while ensuring optimal light scattering performance, balancing performance requirements with manufacturing feasibility.
