When designing an industrial touch display, choosing the right cover glass is just as important as selecting the LCD or touch technology. The cover glass protects the display and touch panel while also affecting durability, optical performance, user experience, and overall product cost.
Two common options are Gorilla Glass and standard cover glass. Understanding the differences can help engineers and product designers select the right solution for their application.
What Is Gorilla Glass?
Gorilla Glass is a chemically strengthened glass designed to provide improved resistance to scratches, impacts, and everyday wear while maintaining a relatively thin profile and excellent optical clarity.
For industrial touch displays that experience frequent interaction or operate in demanding environments, strengthened cover glass can provide an additional level of protection for the underlying LCD and capacitive touch panel.
Potential applications include:
- Industrial control systems
- Medical equipment
- Handheld devices
- Kiosks and point-of-sale systems
- Transportation equipment
- Outdoor electronics
- Smart home and IoT devices
- High-use touchscreen interfaces
What Is Standard Cover Glass?
Standard cover glass can provide an economical and effective protective surface for many industrial display applications.
Depending on the application’s mechanical and environmental requirements, standard glass may be completely adequate—particularly when the display is installed inside an enclosure or is unlikely to experience significant impact, scratching, or repeated physical abuse.
Standard glass can also be customized with different thicknesses, printing, surface treatments, shapes, openings, and other features depending on the design.
Gorilla Glass vs. Standard Glass: What’s the Difference?
The best choice depends on the requirements of the finished product rather than simply choosing the strongest available material.
Durability: Gorilla Glass is designed to provide enhanced resistance to damage compared with conventional untreated glass. This can make it attractive for frequently handled products and demanding industrial environments.
Scratch Resistance: Applications exposed to repeated touching, cleaning, tools, debris, or everyday handling may benefit from chemically strengthened cover glass.
Thickness and Weight: Strengthened glass can provide excellent mechanical performance while maintaining a relatively thin design, which can be important for compact devices.
Optical Performance: Both standard and strengthened glass can provide excellent transparency. Additional treatments such as anti-glare (AG), anti-reflective (AR), and anti-fingerprint (AF) coatings can also be considered depending on the application.
Cost: Standard glass is generally the more economical solution. For applications that do not require enhanced impact or damage resistance, it can provide an excellent balance between performance and cost.
Customization: Industrial cover glass can be customized to match the mechanical design of the finished product, including dimensions, thickness, shape, edge treatment, openings, printing, and surface treatments.
Don’t Forget the Touch Panel
Cover glass is only one part of an industrial touch-display design.
For projected capacitive (PCAP) touch applications, the cover lens, touch sensor, controller, LCD, bonding method, and mechanical enclosure should be considered as a complete system.
The thickness and material of the cover glass can influence touch performance. If a thicker protective lens is required, the touch solution may need to be optimized accordingly.
This becomes particularly important when users operate the touchscreen while wearing gloves or when the product may be exposed to water, moisture, or other environmental conditions.
Optical Bonding Can Further Improve the Display
For demanding industrial and outdoor applications, optical bonding can be used to bond the touch panel or cover lens to the LCD.
Reducing the air gap between the components can help reduce internal reflections and improve readability, particularly in bright environments. Optical bonding can also improve the mechanical integrity of the display assembly.
For outdoor products, combining the appropriate LCD brightness, cover glass, touch technology, optical bonding, and surface treatments can provide a much better result than evaluating any one component independently.
Which Glass Is Right for Your Application?
There is no single answer for every industrial display.
If your product is protected inside equipment and operates in a relatively controlled environment, standard cover glass may provide the performance you need at a lower cost.
If the touchscreen will experience frequent handling, repeated cleaning, potential impacts, outdoor use, or demanding environmental conditions, a strengthened cover-glass solution may be worth considering.
The best approach is to evaluate the complete application, including:
- Operating environment
- Expected impact and scratch exposure
- Display size and brightness
- Touch requirements
- Glove and water operation
- Cover-glass thickness
- Optical requirements
- Cleaning requirements
- Mechanical design
- Target product cost
