Our smartphones have become invaluable daily companions, but with so much reliance comes risk. It’s not a matter of if you’ll drop or damage your phone, but when. As careful as we try to be, accidents happen – whether it’s an unexpected tumble onto hard flooring or an inadvertent scratch against a rough surface.
That’s why finding the right screen protector is so important. None of us want our expensive devices to break due to simple slip-ups. But with so many laminated glass options on the market, how do you know which type is truly best for your needs?
What Is Tempered Glass? A Durable Screen Material Made Through Heating
Tempered glass begins as regular silica-based glass. However, it undergoes an intensive heating and cooling process that transforms its properties and structure.
Regular sheet glass is initially formed and then slowly cooled, yielding a relaxed internal structure with uneven tension. Tempered glass goes through more rigorous treatment. It is heated to an extremely high temperature and then rapidly cooled using jets of air or water. This quick quenching causes the outer surfaces to cool more quickly than the center. The inner portion remains hotter for longer. This uneven cooling results in compressive forces forming on the outside, balanced by proportional tensile stresses inside.
The end result is a glass 4-10 times stronger than standard annealed sheet glass. Its surface is under compression, with the inner layers under balancing tension – making the entire sheet resistant to stress from external forces like impact or thermal shock.
Benefits Of Using A Tempered Glass Screen Protector
Superior Strength And Scratch Resistance
Given tempered glass’s uniquely robust molecular structure, it offers significantly more impact resistance than typical plastic screen shields. They hold up better, resisting scratches from contact with surfaces like coins or keys. Its extra strength means it takes more force to crack or break during a drop onto a hard surface.
Safety During Breakage
When broken, tempered glass also shatters differently than regular glass. It breaks into small, pebble-sized pieces rather than large, jagged shards. This fracture pattern significantly reduces the risk of injury from breaks compared to traditional annealed sheets.
Crystal Clear Visuals
As it uses optically clear strengthened laminated glass rather than plastic films, tempered protectors provide maximum maintained crisp visuals without color shifts or distortion common to some plastic varieties. Your screen looks identical, both with and without the shield intact.
Lifetime Guarantee
Leading brands now offer lifetime guarantees on their tempered protectors. So, if cracks ever form in one spot, they will replace it at no additional cost for the life of your device. This protection provides long-term peace of mind over your expensive smartphone investment.
Potential Drawbacks To Consider
While tempered glass offers several advantages, there are some downsides to be aware of compared to flexible plastic films:
Installation Difficulty: Proper application requires special care to avoid bubbles or misalignment issues – problems that don’t usually plague plastic adhesive protectors. Installation guides and alignment tools are necessary for the best results.
Higher Cost: Tempered glass generally carries a higher price tag than basic plastic protectors. This is due to using strengthened optimized optically-clear glass rather than cheaper polymeric materials.
Incompatibility With Some Cases: Very thin-edged protectors can work perfectly with most cases, but thicker tempered films may bump slightly against lip edges in some bulky cases.
No Self-Healing: Once cracks appear in tempered glass, damaged sections cannot be repaired, like scratches on some reinforced plastic films’ surfaces. The entire protector must be replaced.
Bulky Thickness: While new ultra-thin varieties match plastics, earlier tempered options were thicker and heavier than flexible films, impacting the in-hand feel slightly.
Comparing Tempered Glass To Plastic Screen Protectors
While both tempered glass and plastic screen protectors aim to safeguard smartphones from damage, they each have their own unique set of pros and cons. Let’s examine the key differences between these two popular screen shield materials:
TAMPERED GLASS | PLASTIC SCREEN PROTECTORS | |
Reparability | Requires full replacement | Minor scratches may self-heal |
Durability | Significantly more durable | Are softer and more prone to scratches and cracking |
Clarity | Provides the highest clarity due to using an optically clear material | Exhibit subtle distortions, reflections, or light redirection depending on their specific composition and coatings |
Installation | Easier for DIY users to install without bubbles | Requires special alignment tools. |
Pliability | It may fit phones with nonplanar screens imperfectly. | Conform over various devices’ curved and contoured edges |
When Does Tempered Glass Make The Most Sense?
For users concerned first and foremost with outright strength against impact strikes and scratches, top-tier tempered protectors present excellent value. Situations where tempered glass really shines include:
- Child/student devices are prone to accidental drops.
- Work phones are exposed to environmental hazards like dust/debris.
- Clumsy user histories of past broken screens.
- Phones resold or handed down to ensure future functionality.
- Devices functioning as indispensable productivity tools for job sites.
- Outdoor enthusiast devices face exposure to grit, moisture, and falls.
Meanwhile, simpler, budget-friendly plastic films still suit phones faced with less demanding everyday use where a premium function isn’t as necessary. Like casual users and the elderly, workplace phones are kept in safe premises.
Conclusion
Tempered glass screen protectors emerged as true contenders by delivering uncompromised strength, safety, and optical perfection. Properly installed precision variants avoid past qualms while meeting diverse technology needs. Leading brands now guarantee tempered protectors for life alongside your device investment, and they provide the ultimate long-term value and protection against accidental damage. As portable devices become ever more relied upon and expensive, safeguarding invaluable tools deserves equal consideration.
