Gorilla Glass vs Dragontrail: Which Touch Screen Cover Glass is Best?
When choosing a touch screen cover glass,
two leading brands dominate the market: Corning Gorilla Glass and AGC
Dragontrail. Both offer scratch resistance, drop protection, and optical
clarity, but they differ in performance, cost, and reliability.
This guide compares Gorilla Glass vs
Dragontrail to help you decide which is best cover glass for your smartphone, tablet, or
wearable device or industrial displays, HMI display.

Industrial-Grade Cover Glass Selection: Gorilla Glass vs Dragontrail for Harsh Environments
Unlike consumer electronics, industrial
devices face extreme conditions:
• Chemical
exposure (solvents, oils, cleaning agents)
• Thermal
shocks (-40°C to +85°C operation)
• Mechanical
stress (vibration, impact, abrasion)
• UV
degradation (outdoor sunlight exposure)
This expanded guide compares Corning
Gorilla Glass and AGC Dragontrail for industrial applications, with new data
on:
• Chemical resistance testing
•Thermal cycling performance
• UV stability metrics
•Anti-reflective solutions for HMIs
