What's Inside Your Tempered Glass Screen Protector?

Learn how a simple, three-layer solution can revolutionize your smartphone's protection. Uncover the science behind tempered glass screen protectors and why they're the ultimate shield against everyday wear and tear.

Key Takeaways

  • Tempered Glass: A type of glass that is heated and then rapidly cooled. That makes it significantly stronger than regular glass.
  • Screen Protectors: Thin sheets of tempered glass designed to protect smartphone screens from scratches and impacts.
  • Multi-Layer Design: Screen protectors consist of a few layers.
  • Oleophobic Coating: A special coating that repels oil and fingerprints, making the screen easier to clean.
  • Anti-Glare Coating: A coating that reduces reflections and improves screen visibility in bright light.
  • Evelatus: a wholesale supplier, offers premium tempered glass screen protectors in bulk at competitive prices.

How Tempered Glass Protects Your Screen

Tempered glass screen protectors offer superior protection for your device's display. Engineered using advanced heat treatment, this technology transforms ordinary glass into an exceptionally strong and durable material. The glass is heated to extremely high temperatures and then rapidly cooled, a process that compresses the surface and significantly increases its strength. This molecular transformation results in a screen protector that is up to five times stronger than standard glass of the same thickness.

To further enhance its protective capabilities, tempered glass undergoes rigorous testing, including simulated drops and impacts. These tests ensure that the screen protector can effectively absorb shock and prevent the glass from shattering into dangerous shards.

Precision-cut to fit your device's display perfectly, tempered glass screen protectors provide seamless coverage and bubble-free application. This protective layer is incredibly resistant to scratches, safeguarding your device's screen from everyday wear and tear, such as those caused by keys, coins, and other hard objects.

Tempered glass screen protectors typically consist of three layers:
  1. Tempered Glass Layer: This is the main layer that provides the protection. It's made of chemically treated glass that's been heated and then rapidly cooled, making it incredibly strong and resistant to scratches and impacts.
  2. Adhesive Layer: This thin, clear adhesive layer firmly secures the screen protector to your device's screen without leaving residue upon removal. It's designed to be strong enough to hold the glass in place, even after cracking. The evenly spread adhesive bonds to the phone's screen, keeping glass fragments adhered even when the screen protector is damaged.
  3. Oleophobic Coating (Optional): This is an optional layer that helps repel oil and fingerprints, making the screen easier to clean and less prone to smudges.

Ensuring a Smooth Application

Bubble-free application is achieved through an adhesive layer, approximately 0.1 mm thick, applied in a grid pattern of microscopic droplets. When the protector is pressed onto the screen, these droplets spread out and merge, seamlessly filling gaps and eliminating air bubbles. This ensures the adhesive layer remains thin and even, preserving the screen's touch sensitivity and responsiveness.

The right design prevents any lifting or bubbling at the edges, but the precision cutting of the tempered glass further is what really facilitates a smooth application process. Designed to match the exact dimensions and contours of specific phone models, the protector fits perfectly without interfering with front-facing cameras, sensors, or speakers.

Maintaining Touch Sensitivity with Tempered Glass

Tempered glass screen protectors preserve a smartphone's original touch sensitivity thanks to their ultra-thin design and advanced adhesive technology. The glass, typically around 0.3 mm thick, is sufficiently thin to allow the capacitive touchscreen to accurately detect the electrical signals from your fingertips.

This thinness ensures that your finger remains within the optimal distance from the touch sensor, maintaining responsive touch performance. Additionally, the oleophobic coating on the glass surface reduces friction, allowing your fingers to glide smoothly across the screen.

The adhesive layer further contributes to maintaining touch sensitivity. Engineered to be as thin as 0.1 mm, the silicone-based adhesive minimizes interference with the touch sensor. Its uniform application across the screen protector ensures consistent contact between the glass and the display, preserving the device's original touch experience.

Capacitive touchscreens detect the electrical conductivity of your fingertips. By keeping the glass layer and adhesive layer as thin as possible, screen protectors minimize the distance between your finger and the touch sensor, ensuring accurate detection of your touch inputs.

Antiglare Technology

The anti-reflective coating on the glass surface comprises multiple layers of metal oxides, including silicon dioxide and titanium dioxide. These layers have different refractive indices, meaning they bend light at different angles. As light passes through these layers, the reflections from each layer interfere with one another, significantly reducing the amount of light reflected back to your eyes. This results in a clearer and more readable screen, especially in bright conditions.

Additionally, the anti-glare coating diffuses ambient light, reducing the intensity of reflections and eliminating the mirror-like effect often seen on untreated screens. It's important to note that not all tempered glass screen protectors include this anti-glare coating.

Leading Manufacturers of Tempered Glass

There are several companies that produce high-quality, impact-resistant glass solutions. Asahi Glass Co. and Corning Inc. are two major players in the market for durable glass used in smartphones and detachable protectors. Both companies produce high-quality, impact-resistant glass solutions, and their products are often compared and contrasted in terms of strength, durability, and other features.

While Corning Inc. is well-known for its Gorilla Glass series, Asahi Glass Co. offers the Dragontrail series. Both companies are constantly innovating to provide the latest advancements in screen protection technology.

Oleophobic Coating

Oleophobic coating is a thin, transparent layer applied to the surface of tempered glass screen protectors to repel oils, fingerprints, and smudges. This coating is typically made of fluoropolymers, which have low surface energy. When oils from the user's skin come into contact with the oleophobic coating, they tend to bead up and can be easily wiped away without leaving residue. This helps maintain a clear, pristine screen and reduces the need for frequent cleaning.

The oleophobic coating also enhances the user experience with smoother finger gliding.

High Quality Checklist

When looking for a high quality strengthened glass display protector, make sure it possesses the following qualities:
  • 9H hardness for superior scratch resistance
  • HD clarity for uncompromised visual quality
  • Rounded edges for a seamless, comfortable feel
  • Anti blue light technology which reduces eye strain
  • Highly responsive touch sensitivity
  • Compatible with 3D touch functionality
  • Anti-scratch coating for long-lasting durability
  • Bubble-free application for a flawless finish

Environmental Implications

Tempered glass screen protectors offer superior protection but have environmental implications. Their manufacturing process is energy-intensive and can contribute to pollution. Additionally, raw material extraction can impact the environment.

However, tempered glass is 100% recyclable, making it a sustainable choice when properly disposed of. Recycling reduces the need for new materials and energy-intensive production.

While tempered glass is more durable than plastic alternatives, reducing the need for frequent replacements, its manufacturing process remains energy-intensive.

By choosing tempered glass and disposing of it responsibly, you can minimize the environmental impact of your device protection choices.

Conclusion

In today's world of fragile smartphones, a tempered glass screen protector is an essential accessory. Its multi-layered design, combined with advanced technologies like oleophobic coatings and anti-glare treatments, offers unparalleled protection against everyday wear and tear.

By understanding the science behind tempered glass and its various components, you can make informed decisions when choosing a screen protector. Investing in a high-quality tempered glass screen protector is a simple yet effective way to extend the life of your smartphone and ensure its continued performance.
