Tempered Glass: By installing tempered glass in the phone, the phone gets a protection. If ever the phone is dropped from the hand or falls on the ground, then due to the tempered glass, the screen is saved from breaking. If you have not installed tempered glass, and your phone falls down and breaks, then people start telling your fault as to why the tempered glass was not installed. This has become a one-sided talk of tempered glass, but you must have seen that many types of tempered glass are available in the market. These include many tempered glasses like 2D, 3D, 4D, 5D, 9D, 11D.
If you go to a shop to get tempered glass fitted, then the shopkeeper shows you various categories. 2D, 2.5D, 3D, 4D, 5D, 9D even 11D. Now what does all this mean, and which one is right for your phone? Let’s know about this.

Tempered Glass 2.5D
Some time passed and now a little curve is being given in the smartphone. For this, 2.5D glass was introduced in the market. A slight curve is given in their corner. In most smartphones, only 2.5D tempered glass is used. It is possible that the same has been used in your smartphone as well.
Tempered Glass 3D
In 3D, more curves are given on the edges as compared to 2.5D. Also clear here that the “Curve Rating” officially stops at 3, since the “D” is used for dimension.
2D, 2.5D, 3D
2D tempered glasses are flat. 2.5DX and Y planes and 3D are X,Y and Z planes.
What is the meaning of 4D, 5D, 9D, 11D?
4D, 5D, 9D or 11D nothing really happens. It is simply used to fool you. Actually, people started to think that D is used for hardness, and the higher the D, the stronger the tempered glass. In such a situation, the companies also started fooling the users. This can be called a marketing gimmick. Companies introduced 4D, 5D, 9D even 11D, while the dimension is limited to 3. Tempered glass sold in the name of 11D glass is also 2.5D glass. Note that the hardness is denoted by “H”.
