Tempered Glass Information

Tempered Glass comes with many different Features and this page tries explaining the meaning of each one

Tempered Glass Basic Information

Tempered glass screens have two very important features that plastic ones don’t. They offer far better resistance against scratches and drops, and they closely mimic the feel of your actual screen, which makes them much nicer to use. These two features alone mean it makes perfect sense to go with a tempered glass protector.

What is 2D and 2.5D Tempered Glass?

When we talk about a 2D glass screen, it refers to a pure, flat screen.

This relates back to a time when smartphone screens were just flat, where all the points on the glass are in the same, flat 2D plane. Whilst a 2.5D glass screen has a slight curvature towards the edges giving an improved ergonomic and aesthetic feel. This means a smoother feel to the edge of the glass and and improved swiping, although just like a 2D screen, the middle area is flat.

This image shows how the 2D edge is a square or straight edge, and the 2.5D edge is a curved and smoothed edge.

What is a 3D Tempered Glass ?

A 3D glass screen generally refers to a larger curved area of the glass (full-screen), such as Samsung’s Galaxy series. It not only protects the glass surface but also the electronic display panel, which is essentially different when comparing it to a 2.5D glass screen. This type of screen protector is also sometimes referred to as 5D or 9D.

This image shows the 3D edge as a simulated graphic.

Hardness –

The 4H, 6H, 8H and 9H actually refers to the Pencil Hardness test or scale, with different grades of pencil being used to check how hard something would to be to mark the screen protector.

For example

A tempered glass screen protector with a 9H hardness rating will resist scratches from items in your pocket or bag such as keys or loose change

Tempering time

During the manufacturing process of the tempered glass the glass undergoes a heat treatment process in which it travels through a tempering oven, either in a batch or continuous feed. The oven heats the glass to a temperature of more than 600 degrees Celsius. This is the tempering time, most commonly around 2 hours

Can a screen protector be removed ?

In short yes, follow the below sequence (or watch embedded video)

1. Use a removal tool or credit card

2. Start from one corner and slowly wedge under glass.

2. Slowly slide under the full length of the screen until fully removed

Please note this video is not supplied by us but is a good example of how to remove a damaged screen protector.
