Intro
This project addresses a common optical challenge in industrial HMI display systems: excessive screen glare under strong ambient lighting conditions. To solve this, Felix Glass developed a customized AG anti-glare coated optical cover glass combined with a tempered glass substrate to improve both display clarity and surface durability.
⸻
Core Challenges
• Strong ambient light causes severe screen glare, reducing display readability
• Standard glass surfaces easily accumulate fingerprints during frequent touch operation
• Insufficient scratch resistance under industrial usage conditions
• Non-standard display dimensions require fully customized fabrication
⸻
Our Customized Optical Solution
• Substrate: Thickened soda lime optical cover glass with tempering treatment
• Coating: AG anti-glare matte coating combined with AF anti-fingerprint layer
• Precision CNC cutting and edge polishing for exact installation fit
• Full-size customization according to industrial HMI requirements
⸻
Technical Highlights
• Surface reflectance reduced to below 8% after AG coating
• AF coating significantly improves fingerprint resistance
• Tempered glass increases surface hardness and scratch resistance
• Dimensional tolerance controlled within ±0.02 mm for industrial precision fitting
⸻
Application Range
This solution is widely used in:
• Industrial control panels
• Machine vision display terminals
• Factory automation systems
• HMI (Human-Machine Interface) equipment
⸻
Project Outcome
The AG optical solution effectively eliminated glare issues, enabling clear screen visibility even under strong lighting conditions. Combined AF + AG surface treatment significantly improved operational durability and extended service life in industrial environments.
