Choosing Between Glass+Glass vs. PET+Glass for PCAP Touchscreens
In the world of touchscreens, what lies beneath your fingers matters as much as the display itself. Two leading structures dominate the market: Glass+Glass (G+G) and PET+Glass (Film+Glass). The key isn’t about which is better in general, but which is best for your application.
1. PET+Glass: The Lightweight Contender
Structure: A flexible PET film forms the top touch layer, bonded to a bottom glass display layer.
Advantages:
-
Lower cost and reduced weight
-
High shatter resistance, ideal for mobile devices
-
Enables ultra-thin form factors
Trade-offs:
-
Less scratch-resistant (~3H hardness)
-
Slight optical haze or "orange peel" effect
-
Vulnerable to UV, abrasion, and chemicals
-
Feels less premium than glass
2. Glass+Glass: The Premium Performer
Structure: Hardened cover glass serves as both the surface and sensor layer, laminated to the display.
Advantages:
-
Crystal-clear optical performance (>90% light transmission)
-
Exceptional scratch resistance (6H+ hardness)
-
Long-term durability in UV, heat, and chemicals
-
High-end tactile experience and excellent stylus support
Trade-offs:
-
Higher cost and heavier structure
-
More prone to shattering on sharp impact
-
Slightly thicker module profile
3. When to Choose PET+Glass:
-
Budget-focused consumer devices
-
Weight-sensitive or ultra-slim devices
-
Drop-prone use environments
-
“Good enough” display clarity
4. When to Choose Glass+Glass:
-
Demanding environments (factories, vehicles, outdoor)
-
High-end electronics needing premium touch feel
-
Use with active stylus or for medical/automotive displays
-
Where longevity and scratch resistance are critical
5. Other Considerations
-
Manufacturing: PET+Glass is simpler and more affordable to assemble; G+G needs more precise lamination.
-
Hybrid Trends: Emerging designs like CG+Film and UTG (Ultra Thin Glass) offer a mix of both worlds.
-
Coatings Matter: Anti-glare, anti-fingerprint, anti-scratch layers dramatically impact final usability and should not be overlooked.
🧠 Final Thoughts:
There’s no universal winner. Choose based on price point, usage environment, durability needs, and user experience goals. The right touch starts with the right layers.
