Basic Overview

Terms like double-tempered or triple-tempered glass are frequently used when purchasing a smartphone screen protector. These labels are more than just advertising terminology. They explain how the glass is reinforced and how effectively it can shield your phone. Stress management, durability, edge protection, and long-term stability are where the true differences reside.

To assist you in selecting the best choice, this book provides an understanding of these distinctions using actual performance data and tried-and-true industry standards.

The Strengthening Process of Tempered Glass

By applying stress on its surface, tempered glass becomes more resilient. There are two primary techniques for strengthening:

1. Physical (thermal) tempering

Glass is heated to extremely high temperatures in this process, and significant air pressure is used to swiftly cool it down. Surface compression is produced as a result, aiding in impact resistance.

1. Strong resistance to impact
2. For safety, breaks into tiny, blunt bits.
3. Weakness: edges, particularly sharp corners, are prone to chipping.

2. Ion exchange, or chemical strengthening

Here, heated potassium salt is used to soak the glass. The glass’s surface becomes denser and tougher as larger potassium ions take the place of smaller sodium ions.

• Increased compressive stress
• Increased resistance to scratches (9H level)
• Improved durability over time

The majority of current screen protectors combine the two techniques.

Single, Double, and Triple-Tempered Glass

One-Tempered Glass

• Exclusively makes use of thermal tempering. It is typically featured on inexpensive screen protectors and offers rudimentary protection.

Double Tempered Glass

• Thermal tempering and one round of chemical strengthening are combined to create double-tempered glass. This enhances clarity, hardness, and impact resistance. It is reasonably priced and appropriate for everyday usage.

Glass with Three Temperatures

• Adds sophisticated treatments, including as dual ion exchange, stress balancing, and edge reinforcing, to double tempering. As a result, the entire glass surface is strengthened and protected more evenly.

In contrast to double-tempered glass, triple-tempered glass provides:

• Increased impact resistance by up to 50%
• Improved durability of edges
• Increased transmittance of light (clearer display)
• Significantly reduced chance of spontaneous breaking

The Reasons Triple-Tempered Glass Is More Dependable

To increase uniformity and safety, triple-tempered glass undergoes additional procedures:

• Internal flaws that result in abrupt cracking are eliminated via homogenization treatment.
• Dual ion exchange guarantees uniform stress distribution.
• First-impact edge fractures and edge lifting are decreased by 3D curved chamfered edges.

Triple-tempered glass is now more stable thanks to these improvements, particularly for high-end phones.

Which One Is Best for You?

Select Double-Tempered Glass if

• It’s a mid-range phone.
• Mostly, you utilize it indoors.
• You’re looking for affordable, reliable protection.

Select Triple-Tempered Glass if:

• You have a flagship phone.
• You lead an active lifestyle or work outside.
• You want the highest level of touch sensitivity, clarity, and protection.

Basic Information

Every product around this world has a journey and the tempered film is no exception. These days you will hardly find any Smartphone user not using a tempered glass screen protector. But how this excellent product comes into play? How it evolves with the changing time? How important is it for the tempered glass film industry to keep up with the latest technology?  In this article, we will try to give you the narration.

What is a tempered glass screen protector?

The tempered film is a thin piece of glass pasted on the screen of smartphones or tabs to protect the original glass screen. In the past, Smartphone makers came up with different designs where the screen occupied most of the surface area of the mobile phone. To protect the original screen of their Smartphone people used to remove the soft film on the mobile phone screen and replaced it with a toughened glass film to enjoy peace of mind. This happened till the iPhone 4 was on the market.

The arrival of brands like Huawei, OV, Meizu, and Xiaomi from China helped the tempered glass screen protector market as tempered film always gave assurance to the people about the protection of the original glass screen,

Until around the time of iPhone 4, after the button was abolished, people have removed it, But at least buy peace of mind.

Types of tempered glass screen protectors as per the phone models

There was a time when the 2,5D curved glass screen of smartphones was popular. Taking the queue from the manufacturers of Smartphones, makers of the tempered film started producing 2.5D tempered glass screen protectors but they faced many problems including managing all the arcs at the edges and glue that was unable to stick to the phone’s surface due to curved corners of smartphones.

So, tempered glass screen protector is divided into different categories.
Two main categories are
Full Cover | Half Cover

Then there are sub-categories like –

full fit | pseudo full fit | Fully covered and fully fitted | full glass | non-full glass | Fully covered, fully laminated, all glass

Furthermore, you will find that there are two kinds of pseudo-full fit.

1. Half-covering: This type is a bit smaller than the screen itself, and for that reason, the curved area of the screen is exposed. Half-covered or semi-covered tempered film always leaves some white edges. There are iPhones ( from series 6 and up) and the latest versions of Android phones will face the problem of having ‘white edges’ if users installed half-cover tempered glass no matter how stupid the mold factory is, it is complete, the minority Android phone, the semi-covered tempered film will still have white edges, so you need to use “white edge filling fluid” to fix it.

But this is a short-term solution just to cover it up, not the final fix.. After a few days, the oil will be squeezed out, and the edge of the tempered film will be dirty.  The best solution found so far is a kind of UV glue also known as optical glue.  

2. Fully covered and fully fitted

These full-cover tempered films will block the exposed areas as the purpose is to prevent white edges. Divided into “full glass” and “non-full glass”

All glass or Full Glass

Although as per the name and claim this tempered film covers white edges but there are cases where you may find that edges may not be attached in a proper way. Moreover, the lifespan of this tempered film is low and corners can break with a light touch.

Arrival of 3D

To solve this problem, tempered film manufacturers came up with a new product- 3D curved tempered glass. Here in some cases, manufacturers use cold carving technology, and some use hot bending technology. The lifespan for this type is a bit longer and the sense of towering is much lower.

Disadvantages you may face

Tempered film rupture

Framed Tempered Glass Screen Protector  

The structure of the two is roughly the same, the screen area is still glass, but the edge frame is partially replaced with non-metal or plastic, which is called a soft-edged tempered film. This particular product completely solved the problem of low existence rate. Fitting too is really good.

You will also get the assurance that the tempered film will not be broken even if it is dropped to the edge as durability increases.

Soft edge tempered glass screen protector

In this type, the bottom part is not fully bonded, and it is the same as the top part, and it is also divided into a full glass and half glass. One can use strong double-sided tape to replace the original AB glue on the back of the whole sheet. there will be dense layers of dots in the exposed area of the screen to support the touch.

Curved Screen Problem
Once the curved screen first came into the scene, there is no way tempered film will fit fully on taxis with 3D arcs. It can only do the semi-laminated tempered film mentioned above, but even so, poor lamination often occurs.

Enter the solution, Liquid Glue, otherwise known as diluted optical glue.

How to use Liquid glue tempered glass screen protector

In the beginning, drip glue on the screen, then evenly spread it to all the screens, and absorb the excess glue with paper. Then use ultraviolet light to cure after lamination it will ensure no broken edges once fitted.

Con

This is way too expensive which may act as a turn-off.

Even after all these people around the world still favour 2.5D and for most users, semi-covered tempered film is recommended.

So, it’s the people who decide what to take and what to reject. Now you have a fair amount of idea about the journey of Tempered film, you can decide on your own.
