What is the Difference Between 9D and 11D Tempered Glass?

You may have heard of tempered glass or seen it marketed as a feature in gadget specifications or in the form of mobile device screen covers. But what exactly is tempered glass and what’s the difference between 9D and 11D tempered glass? What distinguishes it from traditional glass or plastic screen protectors? Most importantly, what benefits would tempered glass provide you as a consumer, and is it worth the investment?

The fundamental distinction between regular glass and tempered glass is in the manufacturing process. Tempered glass is made by heating and then rapidly cooling the material, giving it a unique structure.

Tempered glass is commonly used in the following applications.

The safety advantages and heat resistance of toughened glass make it a popular material in ovens, coffee machines, computer screens, and windows as well as other appliances. (due to the production process). However, we are particularly interested in its use in mobile phones and other device screen covers.

What does tempered glass mean in terms of your phone?

Tempered glass protectors are typical mobile device accessories that resemble plastic covers in appearance. There are, however, a few significant differences:

  • Thanks to the heat above resistance, tempered glass reduces the risks of your phone being harmed by greater temperatures.
  • Unlike regular glass and plastic phone covers, tempered glass is not easily scratched or damaged.
  • Tempered glass is five times thicker than plastic screen protectors, providing better shock protection. Tempered glass protectors are smoother and more precise than plastic screen protectors, emulating the look and feel of your original phone’s screen.

What’s the difference between tempered glass and screen protectors made of plastic?

Screen protectors are divided into two categories: 

  1. Plastic screen protectors
  2. Tempered glass

You might be unsure whether to use a plastic screen protector or tempered glass at this point.

What is a screen protector made of plastic?

Screen protectors made of plastic are commonly available and have been on the market for a long time. They resemble a little plastic sheet and must be adhered to with extreme caution. They do, however, provide higher drop resistance. However, scratch marks are plainly visible, and plastic screen protectors lose screen clarity over time.

What is a screen protector made of tempered glass?

Tempered glass protectors are constructed of glass, as the name implies. Many layers are present in tempered glass screen protectors (depending on the manufacturer), including Tempered Glass Screen Layers

  1. Anti-shatter film
  2. Oleophobic nano-coating

Finally, on top of the glass, a penetrable silicone covering.

Tempered glass is made by heating it substantially and then swiftly cooling it to make it tremendously stronger and more durable than ordinary glass.

What Should You Think About When Choosing A Tempered Glass Screen Protector?

The scratch resistance of materials is measured in Mohs hardness. It tells you how rigid the material is and whether or not it will scratch your phone’s screen. Take, for example, diamond and glass. The diamond has a hardness of ten, whereas the glass has a hardness of approximately 5.5. If you scratched a diamond across a pane of glass, the glass would be damaged, but the diamond would be unharmed.

A fingernail has a hardness of 2.5 on the Mohs scale, window glass has a hardness of 6, Gorilla Glass 6.5 (Phones with Gorilla Glass Samsung Galaxy S21iPhone 13 ProOPPO Reno6 Pro etc. ) and quartz has a hardness of 7. (the main component of sand) 7. Sand, which is tougher than glass, even the specially hardened Gorilla Glass, is obviously the phone screen’s worst enemy, and sadly, sand is not hard to come by.

A screen protector’s Mohs scale test value will reveal how well it handles scratches.

How about the 9H Difficulty? It means that a 9H pencil, the strongest of all standard pencils, will not scratch the screen. It appears to be unable to withstand the hardness of a knife blade, even though it could provide further protection to your phone screen.

What does D stand for in Tempered Glass?

So basically, D denotes the dimensions of tempered glass, 2D denotes a slightly curved edge, and 3D indicates a more curved glass panel. The ultra-edge prominent compatibility and safety protection of 11D tempered glass.

The new edition of the much-anticipated safety glasses “Tempered Glass” is on its way. Today, we’ll go over 11D tempered glass characteristics, as well as the benefits of 9D tempered glass and which tempered glass is appropriate for your phone.

Difference between 9D and 11D

What is 9D Tempered Glass, and how does it work?

9D Tempered Glass employs a method that uses specific light filters to increase light penetration. To put it another way, the maximum transparency of the glass is guaranteed. For more realistic colour reproduction and image quality, this is required.

The thickness of 9D Tempered Glass is decreased. This is required to improve the quality of touch transmission while maintaining the screen’s sensitivity. 9D is available for a wide range of smartphones. Some brands supporting the 9D are SamsungHuaweiOPPOApple etc.

On the Mohs scale, screen protectors with the designation 9D have a hardness level of 9H. The technology is scratch and shock resistant to a high degree.

In addition, there are no bubbles in the image after mounting. The silicon dioxide antistatic membrane positioned in the top layer makes it possible.

Under the screen protector, there is also additional moisture and dust protection. 9D glass mimics the front of the display’s design most of the time – frames, speaker, camera, and touch sensor connectors, for example. The protective attachment is not visible on the mobile device as a result of this.

Tempered glass is now available in 10D, 11D, 40D, and 100D thicknesses. However, there are no notable changes in strength between 9D and the other ones in general. In 90% of these tags, such as 11D, 40D, and 100D, there is a marketing ploy to “justify” the pricey item.

What is Tempered Glass 11D?

So, taking all of the above into account, 11D Tempered glass is a multi-layered screen protection safety glass that provides strong hardness, a natural viewing experience, a rounded edge, and, most significantly, a smooth feel while playing PUBG, Video Gaming, Chatting, and other similar games. 11D Tempered glass is TEN TIMES more durable than regular tempered glass.

Multitasking with our phone in our day-to-day activities and actions might hurt the original screen and cause harm. So, after receiving your phone, the best back cover and tempered glass are a must-have item for everyone.

11D tempered glass has a screen light penetration ratio of 99.99 per cent, a 3D edge, the optical transmittance of 9H, and an anti-scratch thickness of less than 0.2 mm, making it ideal for easy installation, screen clothing, and laser-cut polishing.

11D is an excellent choice for the latest phones with the edged screen as it covers them fully

Conclusively

As we have discussed above, the difference between 9D and 11D tempered glass provides the same level of hardness according to the Mohs scale, which is 9H. 11D glass is slightly thicker than 9D, but it still provides 99.99 percent light penetration.
