Anti-glare Antireflection Member with Concavo-convex Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand to further increase the visibility of displays, as existing anti-glare/antireflection technologies do not adequately address the issue of visibility enhancement.
Innovation Solution
An anti-glare/antireflection member is created with a base material having a concavo-convex anti-glare layer and an antireflection layer, where the antireflection layer is deposited on the anti-glare layer, and optionally includes an additional antifouling layer, enhancing visibility by reducing surface reflectance and diffused reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an antireflection layer is provided on a base material to reduce surface reflectance, then visibility is improved, but the anti-glare function is insufficient
Solution Approach 1:
The invention divides the surface treatment into two separate functional layers: a concavo-convex anti-glare layer that scatters incident light to reduce glare, and a separate antireflection layer that minimizes surface reflectance. This segmentation allows each layer to optimize its specific function without compromising the other, thereby simultaneously achieving both anti-glare and antireflection properties to enhance visibility.
Solution Approach 2:
The invention combines two previously separate functions (anti-glare and antireflection) into a single integrated structure where the concavo-convex anti-glare layer and the antireflection layer work together synergistically. The anti-glare layer provides diffuse reflection while the antireflection layer reduces specular reflection, and their combined effect achieves superior visibility compared to either layer alone.
2Object-affected harmful factors
If a concavo-convex anti-glare layer is provided on the base material to reduce glare, then anti-glare function is improved, but surface reflectance is not sufficiently reduced
Solution Approach 1:
The invention separates the anti-glare function (handled by the concavo-convex layer that scatters light) from the antireflection function (handled by the separate antireflection layer with optimized refractive index). This segmentation allows the concavo-convex layer to focus on reducing glare through diffusion while the antireflection layer independently optimizes surface reflectance reduction, achieving both objectives effectively.
3Ease of manufacture
If a single-layer antireflection coating is applied to reduce reflectance, then manufacturing is simple, but anti-glare performance is insufficient
Solution Approach 1:
The invention segments the surface treatment into two distinct layers: the concavo-convex anti-glare layer that provides diffuse reflection and the antireflection layer that provides low reflectance. Although this increases manufacturing steps, each layer can be optimized independently, and the combination achieves superior anti-glare performance compared to a single-layer approach.
