As smart devices continue evolving across industrial automation, medical equipment, self-service terminals, smart home systems, and commercial displays, touch screens are expected to provide not only excellent visual and touch performance but also greater reliability and safety.

For many products entering international markets, compliance with safety standards is no longer optional. One of the most important standards today is IEC 62368-1, which introduces higher requirements for electronic equipment safety and material performance.

At DINGTouch, we help customers develop customized touch screen solutions designed to meet demanding environmental and certification requirements, including touch screen cover glass solutions that comply with IEC 62368-1 standards.

What Is IEC 62368-1?

IEC 62368-1 is an internationally recognized safety standard for audio, video, information technology, and communication equipment.

Unlike traditional standards that focus only on specific products, IEC 62368-1 uses a hazard-based safety engineering approach (HBSE) to evaluate potential risks and improve product safety.

This standard focuses on several critical factors:

Mechanical strength

Touch panels must withstand impact, pressure, and external forces without causing hazards.

Material durability

The glass material should maintain stability under long-term use and harsh operating environments.

User safety

Glass fragmentation behavior, structural integrity, and resistance to damage are key factors.

Reliability under environmental conditions

Products may be exposed to:

High temperatures
Humidity
Continuous operation
Mechanical shock
Industrial environments

Because of these requirements, selecting the right cover glass material becomes critical.

Understanding Touch Screen Cover Glass Materials

The cover glass serves as the first protective layer of a touch screen. It directly affects:

Touch experience
Surface durability
Optical performance
Mechanical strength
Safety compliance

The most commonly used cover glass materials include:

Soda-Lime Glass (Standard Cover Glass)

Traditional touch screens commonly use Soda-Lime Glass, sometimes referred to as standard glass.

Characteristics include:

Lower material cost
Good transparency
Suitable for standard consumer applications
Moderate strength
Limited impact resistance

Most ordinary touch screen cover lenses on the market use soda-lime glass due to its cost advantages.

However, for applications requiring stricter safety standards, soda-lime glass may not always satisfy performance requirements.

Soda-Lime Glass vs. High Aluminum Glass: What Is the Difference?

Feature	Soda-Lime Glass	High Aluminum Glass
Mechanical Strength	Standard	High
Impact Resistance	Moderate	Excellent
Chemical Resistance	Standard	Strong
Thermal Stability	Moderate	High
Surface Hardness	Lower	Higher
Thin Design Capability	Limited	Better
IEC 62368-1 Suitability	Limited	Excellent

High Aluminum Glass contains a higher percentage of aluminum oxide, significantly improving overall performance.

Advantages include:

Higher impact resistance

High aluminum glass can withstand stronger external impacts and mechanical stress.

Better durability

Suitable for long-term industrial and commercial applications.

Improved surface hardness

Provides better scratch resistance and maintains appearance over time.

Enhanced safety

Glass breakage behavior and structural performance can better satisfy IEC safety requirements.

Why High Aluminum Glass Is Required for IEC 62368-1 Compliance

For touch screen projects requiring IEC 62368-1 certification, standard soda-lime cover glass often cannot fully meet mechanical strength and safety requirements.

To achieve compliance, many projects adopt:

High Aluminum Glass Cover Lens

High aluminum cover glass provides:

Improved impact resistance
Stronger structural integrity
Better environmental adaptability
Reduced risk of damage
Higher safety margins during testing

This is why many high-end projects choose high aluminum cover lenses as the preferred solution.

At DINGTouch, multiple customer projects requiring IEC 62368-1 compliance successfully achieved certification by adopting customized high aluminum glass cover solutions.

Conclusion

As product safety standards continue to evolve, cover glass material selection is becoming increasingly important.

While Soda-Lime Glass remains suitable for standard applications, projects requiring IEC 62368-1 compliance often need stronger materials with better safety performance.

High Aluminum Glass provides significant advantages in mechanical strength, durability, and certification capability, making it an ideal solution for demanding touch screen applications.
