Video Display Front Panel with Embedded Laser Blocking Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional front panels for large format video displays require multiple thick layers for functional properties like laser blocking, which increase weight, thickness, and complexity, making them difficult to transport and install.
Innovation Solution
A polycarbonate substrate is fabricated to incorporate light-blocking dyes for UVV and NIR light, with anti-glare hardcoats applied on both sides, eliminating the need for separate layers and allowing for a thinner, more transportable front panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate functional layers are used for laser blocking and other properties, then functional performance is improved, but thickness and weight increase
Solution Approach 1:
The patent combines multiple functional layers (laser blocking layer, neutral density layer, anti-glare layer) into a single integrated front panel structure. The laser blocking functionality is achieved by incorporating specific materials and structures directly into the front panel substrate, eliminating the need for separate adhered functional layers. This merging reduces overall thickness while maintaining all required functional properties including laser blocking, neutral density filtering, and anti-glare performance.
2Reliability
If multiple separate functional layers are used for laser blocking and other properties, then functional performance is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single front panel structure, combining laser blocking, neutral density filtering, and anti-glare properties in one unified component. This eliminates the complexity of assembling and aligning multiple separate layers, reducing manufacturing steps and simplifying the overall device architecture while maintaining all necessary functional performance.
3Reliability
If multiple separate functional layers are used for laser blocking and other properties, then functional performance is improved, but weight increases
Solution Approach 1:
The patent consolidates multiple functional layers into a single integrated front panel, eliminating the weight of redundant adhesive layers and separate functional components. By incorporating laser blocking materials and anti-glare structures directly into the front panel substrate, the design reduces overall weight while maintaining all required functional properties.
