Every person wants his smartphone to be in good health for which he takes every step so that his phone is safe from any damage.
The idea of a mechanism to protect an expensive phone with its screen led to the invention of screen protectors.
As everything breaks at its time or when placed under a certain pressure or at a certain angle, but by being careful, the phone can be protected from such angles and pressures.
Screen protectors available in the international market are PET (polyethylene terephthalate/polyester, a type of plastic used to make water bottles and food containers etc.).
TPU (thermoplastic polyethylene, a very flexible plastic), tempered glass (glass with a chemical heat treatment to make it stronger than normal glass) and NanoLiquid (silicon dioxide in liquid form that your phone uses). (protects the screen).
These are considered to be the best tempered glass screen protectors and the good thing is that they are available in the local market.
Initially screen protectors were made in a square shape (called toddy) but the side of the screen we touch the mobile with.
It has a pointed edge, which hurt the face and ears, the edges were rounded to eliminate the technical flaw that gave rise to the 2.5D.
Later, when phone screens began to come with curved edges like Samsung’s Note series phones, screen protectors also curved accordingly to cover the edges, creating 3D protectors.
While they are quite effective at covering the rounded edges of the sides, they don’t cover the top and bottom edges of the phone properly and leave a small gap and are prone to edge breakage.
With most 3D screen protectors there are often complaints of mobile touch sensitivity being affected.
3D was followed by the introduction of 5D screen protectors, in which the edges of the screen protectors are designed with the rounded edges of the screen giving better coverage to the phone screen. Which greatly reduces the chances of breakage.
The touch with it is just like without a protector, i.e. the complaint of affected touch sensitivity with the 3D protector in 5D has been eliminated.
If you really want to protect your phone, buy a good mobile case with a screen protector that further protects the edges and the screen.
