Harms of Bad Quality Screen Protectors

Bad Quality Screen Protectors Give Bad Views

With the development of tech and the wide spread of smartphone, installing glass screen protectors is becoming a common sense. However, if you get a bad quality protector, it will have negative effect on phone screen display. What’s worse, it could even do harms to your eyesight.

The reason why bad quality protectors do harms to eyesight is that they have low light transmittance. Though some manufacturers claim that their products permit 99% light, the highest quality optical glass (used on lens) has a light transmittance of 98% only. As for PET protectors, they can only reach a transmittance of 90%.

Limited by tech and material, general protectors can’t eliminate diffraction though they are of high definition. As a result, screen display could be unclear and would even cause eye discomfort.

Hardness of Screen Protectors

In order to give nice protection, protectors need to be of a certain hardness. The hardest level of PET protectors is 4H, and now it becomes 9H for glass protectors. However, what does 9H mean? Actually, 9H is a comparison to the hardest pencil and is equal to 7 Mohs hardness. Unluckily, though 7 Mohs hardness protectors could resist keys and knives, they can’t deal with sand.

9H actually means nothing in judging the hardness of screen protector. In addition, when all protectors claim 9H on themselves, it is meaningless to focus on it.

How to Judge the Quality of Screen Protector?

Though glass protectors are popular, most customers can’t judge the quality of protectors. Then how to judge their quality?

1, packaging: glass protector are more easily to be broken while transportation, then good quality ones usually come with nice package. On the contrary, bad quality ones have simple protection only.

2, installation accessories: good quality protectors have some installation accessories as enclosure to ensure well installation. As for those bad quality ones, a screen wiper is enough.

3, anti-fingerprint: actually, anti-fingerprint doesn’t mean completely fingerprint proof because there’s no any possible protector. Dropping a drop of water on it is a nice way to judge since a good protector keeps uniting the drop. In addition, a good protector could resist ink pen writing, and that’s another way to judge the quality of protectors.

4, fitness: good protectors use OCA optical adhesive so as to stay slim and enable automatic installation. What’s more, these protectors can be reused for several times. Of course, a bad quality protector doesn’t have these features.

5, burst proof: when a good quality screen protector accidentally broken, it will stop broken pieces from splash.

Blog 0 comments

There Are Really Cheap Tempered Glass Screen Protectors

As normal customers, we would like prices of tempered glass screen protectors to be as cheap as possible. Average prices of them are between $5-$10, but there are some as cheap as plastic protectors. How is that possible?

How Do Extremely Cheap Tempered Glass Screen Protectors Exist?

Since prices of average quality protectors can’t be really cheap, how do these really cheap ones exist? Here are mainly 5 reasons:

1, suppliers are promoting, and prices will rise not long. This is the best chance to buy and will not have to worry about quality problems.

2, suppliers use bad quality material. Some suppliers and manufacturers use 0.4mm glass and bad quality glue, so that the cost is low. However, such glass protectors give bad hand feelings and can’t fit well. What’s worse, they even have bad influence on screen display and eyes.

3, suppliers cheat on labour. Generally, tempering processes take 3-6 hours, and only after 6 hours tempering, can the protector be really hard. Bad quality protector production may even doesn’t include tempering process, thus giving no protection. They can even be dangerous to users after being broken into pieces.

4, suppliers cut down coating process. Some suppliers would choose not to coat glass protectors with fingerprint oil. As a result, these protectors can not resist dirt and fingerprint, and in addition, provides no smooth touching.

5, suppliers sell substandard products.

How to Judge the Quality of Tempered Glass Screen Protectors?

There are also 5 ways to judge whether a glass screen protector is good or not:

1, light transmittance. A good quality screen protector should at least be at a light transmittance of 92%. As a result, it could enable HD screen display.

2, protection. This protection means to stops glass pieces from flying after being broken, thus protecting human safety.

3, touch feelings. Good quality glass protectors enable smooth and nice touch feelings, which bad quality ones don’t.

4, self-cleaning. A good glass screen protector should be resistant to fingerprint, dirt and water. Even if it gets dirty, we can easily clean it.

5, perfect matching. Whatever model you choose, it should fit corresponding smartphone. When it doesn’t f it well, it must be a bad quality protector.

Blog 0 comments

Glass Screen Protector Offers Nice Protection

Glass screen protector, as the most popular solution to protect phone screen, offers really awesome protection. We can simply take glass protectors as an additional screen, and they could minimize the possibility of damage to original screens. In addition, after being specially processed, glass protector could be more resistant to fingerprint and dirt.

Material of Producing Glass Screen Protector

Some people may think manufacturing processes of glass protectors do not include much technology. However, the glass raw material is complex enough for most people to understand.

The main material for making glass screen protectors is glass, and there are countless glass suppliers.

Of course, those really good quality protectors are made of materials from AGC, SCHOTT AG and Corning. Then what are the differences between good and bad quality glass protector? The main difference is their light transmittance, and the higher the transmittance, the better the quality.

Features of Glass Screen Protector

1, HD display: glass protectors should at least be at a light transmittance of 90%. Only if above this transmittance can they enable HD screen display and protection to eyes.

2, Resistant to scratch: glass protectors are long time tempered so that they are of great hardness. Usually, glass screen protectors are at a 6.5 Mohs Hardness, which means they could resist knifes and keys. However, those plastic ones can’t resist even wood materials.

3, Resistant to fall: glass protectors could work as cushions to phone screen. Even if you drop your phone accidentally, they could protect the screen well from damage.

4, Ultra thin: glass protectors are usually at thicknesses of 0.15 to 0.4mm. The thinner the protector, the better you phone will look. Besides, an ultra slim protector would offer nice hand feelings and equal protection to those thick.

5, Dirt proof: we coat most glass protectors with fingerprint oil and then electroplate them. After these processes, they could enable smooth touching and be resistant to dirt, fingerprint and water.

6, Auto-installation: unlike plastic ones, glass protectors do not require complicated installation process. You can simply match holes on phones with those on protectors, and then place them to screens, installation is quite easy.
