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.
