iPhone 12 series 3D curved tempered glass screen protector

iPhone 12 series 3D curved tempered glass screen protector

3D curved Tempered Glasses mainly designed for curved surface mobile phones.

True 3D shaping allows the flat plane to be curved, providing the perfect fit necessary for rounded edge devices.

Product Detail

Nowadays more and more smartphones with curved edge,  “3D curved” glass screen protectors are made to match those curves.

In order to user comfort is much higher and glass is fully attached to the phone, OTAO developed 3D curved tempered glass screen protector, by using of chemicals to corrode the glass to make the glass appear grooves, and then go to the CNC engraving machine for engraving treatment. 

OTAO 3D Curved Glass Advantage

 3D Full Cover(edge to edge).

 Touch Sensitive.


As for the light transmittance, it will directly affect the comfort of viewing the screen, so this is also more important.

In order to save costs, many factories will use inferior anti-peeping materials, not only the anti-peeping angle is too large, but the light transmittance is also very low, probably only 40%-50%, and users will feel discomfort after watching the screen for a few minutes.

Easy Installation

The installation of OTAO tempered film is very simple and convenient. If you are considering the terminal, you can also choose our applicator(also called installation tray)to assist the installation. Even a consumer without film experience can easily put a film on it.

9H hardness

Please note that 9H in the tempered glass industry actually refers to pencil hardness, not the well-known Mohs hardness (Pencil 9H Hardness = Mohs 6H Hardness). Each batch of OTAO tempered glass needs to pass the strict Japanese Mitsubishi 9H pencil load hardness test.

Strongest Glass Screen Protection

The aluminium-silicate glass and the tempering technology used in OTAO Tempered Glass to increase the surface tension of the glass making the full body stronger.

Maximum Scratch Protection

OTAO Tempered glass uses premium glass material and special hard coating treatment.So it prevents most of scratches in daily life by such as blades, scissors, keys and other hard, sharp objects above the ground scraping.

Delicate Smooth Oleo-phobic Coating Treatment

The fingerprint problem is really annoying because it reduces the visibility of the screen. In addition, there are problems such as water spraying and dripping oil, which make the situation worse.

But these things don’t happen in OTAO tempered glass screen protector.So the typing and touching the phone surface are much easier and hassle-free.

We use plasma spraying and electroplating processes to evenly spray the fingerprint oil imported from Japan on the glass film to achieve a lasting hydrophobic, water- and oil-repellent effect.

Bubble Free & Dust Free

In order to save costs, many factories produce in a non-dust-free environment, and it is easy to absorb dust into the product AB glue, and some dust is difficult to be found if it has not undergone strict quality inspection after production, until they are attached. You can see it on the phone, it's too late.

Some factories use low-quality AB glue, and air bubbles may also appear.

OTAO adopts high-standard quality inspection procedures, from raw materials, production environment, production process to final storage, strictly controls, and delivers a qualified dust-free and bubble-free tempered glass screen protector to you.
