The points one must follow –


THICKNESS

The current mobile phone market of glass screen protector is now paying attention to the thickness of the material.

In general, the demand of 0.2mm, 0.3mm, 0.4mm grades are high. Some of the points that are ruling the market are –
a) Thinner is better
b) Transmittance quality of thinner product is better
c) Toughness of thinner products are good

These days, the market  & consumers’  favorite is 0.33mm tempered glass protector and MPG tempered glass screen protector manufacturer produces excellent products in this segment.

CUTTING PROCESS

Cutting processes are generally three kinds: Flat edge, 2.5D arc edge, 3D arc edge.

Flat Edge -In this process, flat edge of the tempered screen protector is cut to the desired size at right angle. It’s done without polishing,
2.5D Arc Edge -Here, tempered glass screen protector is going through the glass sweep machine chamfering and the product feels smoother.
 3D Arc Edge –In this process, tempered glass screen protector to go through the hot bending machine.

Please remember, the more complex the process is the higher the corresponding cost become thus the price of the end product become more expensive.

Now a lot of businesses and 4d/5d,9d,10d

OLEOPHOBIC COATING


An oleophobic coating is an oil repellent coating used in Smartphone and screen protectors. It can make materials fingerprint resistant because they repel the oils that are produced by the skin. These days you can find that oleophobic coatings are being used extensively to make smudge resistant touch screens for smart phones and tablets.

In fact, the low-end glass and high-end glass is often differentiated by the use of the oleophobic coating. In China, OEM screen protector screen protector wholesale market is flooded with various tempered glass screen protectors with varied qualities.

Difference
In China, there are two processes that are being followed –
a) machine spraying and b) ordinary artificial spraying.  It’s proven that machine spraying is always gives far better result than ordinary artificial spraying.

But you will hardly know the truth from the makers because not every factory and product will explain what process they use.

Some businessmen in China try to convince their clients with the logic that one layer of thin oil layer will be added on the surface of toughened tempered glass screen protector. But this only means that the residue of fingerprints can be reduced and wipe up more easily, but it cannot completely eliminate fingerprints.

But the same thin oil layer will be divided into three processes.

MANUAL ANTI-FINGERPRINT OIL

That product is used with a brush. In this process, anti-fingerprint oil is used directly on the surface of the toughened tempered glass screen protector with the help of a brush.  The disadvantage is that the anti-fingerprint effect is not uniform, and easy to rub off;

PLASMA SPRAY ANTI-FINGERPRINT OIL

This one is better than hand-painted, anti-fingerprint layer can last about 20 days; its invisible nano-coatings can also be combined with anti-bacterial effect.

ELECTROPLATING ANTI-FINGERPRINT OIL

The electroplated anti-fingerprint oil on the surface of a tempered cell phone glass refers to a surface processing method with the help of which fingerprint oil is precipitated on the surface of the tempered glass through electrolysis to form a plating layer.

1. steel film wear better, steel wool friction up to 3000 times, more durable scratch;

  1. tempered film more durable anti-fouling, the surface is not easy to leave fingerprints and easier to erase;
  2. This film is affixed to the screen, the sliding screen is smoother without delay, and highlight color HD is more real.
    The coating has new features in the original matrix properties.

In case of Oleophobic coating, how you feel the phone while touching is the best way to know the effect of the product.

But one must understand even if one apply best anti-fingerprint technology, anti-fingerprint effect can only last 6 months to give its top level performance . It loses its shine and effect after that due to constant use.

———————————

GLUE LAYER

Thickness of glue will affect the tempered glass screen protector after the thickness of the glass. Generally, thicker AB Glue always performs better whereas plastic layer treatment and QC are not good for the screen protector as later two can gather dust and bubbles.

Remember, discharge speed, bubble and white edge can hamper the performance of the glue. The thicker the AB gum exhaust the slower, but the thicker the AB gum white edge effect is better.

Just for your knowledge, white-edge appears at the outermost part of your phone in the form of snow-white color thus produces big color difference with the inner black screen.

Generally speaking, the white edge and glue layer is bigger, part of the situation can be solved with white edge liquid but also cannot entirely solve the situation.

Moral of the topic: the thicker the AB ANTI-WHITE EDGE THE BETTER IS THE RESULT.

FULL COVERAGE & NON-FULL COVERAGE

This is another area where people should pay attention to.
Full coverage
When you are talking about ‘Full Coverage’  of your Smartphone with  toughened screen protector you are actually thinking of curved tempered-glass  screen protector that offers edge to edge protection thus providing maximum image clarity and remarkable touch sensitivity.

It also stimulates the effect of the visual non-sticking screen protector for your Smartphone.

of the toughened screen protector of the, but it is easy to have a problem that one-handed operation is easy to be mishandled

Non-Full-Coverage
In this case, instead of fully covering the phone screen protector non-full-coverage screen protector mainly covers the display Pixel area. Here, the disadvantage of course is that presence of a screen protector is bare to your open eyes and causes visual distractions.

High end phone such as iPhone x, in particular, has a full-screen display, so Apple officially didn’t recommend using a fully-covered membrane but it’s advisable to use full coverage screen protector for your phone.

———————————
APERTURE IN RECEIVER AREA –

Applying the tempered glass screen protector on the surface of your Smartphone needs special care and attention. Some of the protectors are not full and some of them are fully cover the phone’s top surface.
Except for the earpiece area and areas with small openings where dust can gather easily.

Entire surface needs proper attention and the full glue must be applied thoroughly. Always choose the product that has better glue and better surface cover.

SECONDARY STRENGTHENING PROCESS

In this process, tempered glass screen protector need to goes for tempered for 4hours and also goes through a special method to improve the hardness and impact resistance of the material. Products that are coming out if this second strengthening process of tempered glass screen protector are high on hardness and its  impact resistance is stronger. Moreover, one rarely finds any broken edge.

—————————————-

SHATTERPROOF

People always hope to have shatterproof display that does not break into pieces upon impact. Millions of users have gone through the traumatic experience of seeing their expensive Smartphones meet its demise with the hard and unrelenting pavement, or different hard surfaces.

Shatterproof glass membrane fragments won’t fly out thus preventing secondary damage. It’s like a car windshield but only difference is here that the glue matters. Not all Bulk tempered glass screen protector suppliers and manufactures in China are providing this feature but some high-end membranes manufacturers do pay special attention to this.

———————–

TRANSPARENCY

The thumb rule is – The higher the number is the better is the transparency.  But you need professional help and equipments to test the truth.   So, if any label says the transmittance is 9 xs% then we has no way to know the truth.

For example – Many cell phone screen protector packaging will mark the “transmittance of 99%”, this statement is not based on science, and can deceive consumers and their buying behavior.

Remember, the standard transmittance data should be: ≥90.0%.

Also, the high-end glass won’t affect the transparency of the screen protector.

————————————

GLASS MATERIAL

The material of mobile phone glass membrane is mainly aluminosilicate glass. Aluminosilicate glass also has different manufacturers, for example –Asahi Glass.

Most of the tempered glass screen protector factories in China are using Japanese Asahi Pin and Chinese high-alumina glass for their production. This is due to the reason of triple digit price of Khang Ninh Gorilla glass compared to normal glass available.


HARDNESS

In general, wholesale tempered glass screen protectors are made of tempered glass screen protector with hardness between 6 ~ 7 H where H of pencil hardness is the base of hardness.  The highest hardness parameter goes till 9H.

Please remember, tempered glass screen protector with 6 ~ 7 can handle metal, but not gravel.

———————————

IRIDESCENCE

Iridescence affects the transparency of the tempered glass screen protector and the visual effect of the screen. Caused by weathering on the surface, the iridescence, and the interplay of lustrous, changing colors, is due to the refraction of light by thin layers of weathered glass.

Another fact that drives iridescence fast is the grease on the screen itself. Glass screen protectors do attract grease if the product quality is bad.

Generally, tempered glass screen protector supplier of China and
tempered glass screen protector manufacturers provide a clean screen protector part of the package is to solve this problem.

———————————–

WATER DROP ANGLE

Finding the ‘Right’ one is always tough especially when there are many cell phone membranes on the market under the banner of “3d hand condensate Membrane”.  Here is a small test that we can recommend you to ensure the cell phone’s membrane is good or not.

We call it Drop test – Let a drop of water fall on the surface of the flat cell phone membrane, if the water drops are spread with the angle less than 110, then the steel technology of this mobile phone membrane is not very good.

We always advise our consumers to try this ‘Drop Test’ before buying a phone. Remember to pick the one where the shape of the drop remains relatively rounded.

—————————–

DEGREE OF WEAR RESISTANCE

Rules are quite straight here and we follow them. Professional test is conducted with #0000 steel velvet where each piece of mobile phone screen protector must weather Friction 3000 times to pass the wear resistance test.

When consumers choose and buy the product, they should pay attention to the fact that the mobile phone membrane has a shelf-life. Nothing goes forever, so is the anti-fingerprint layer of the phone’s screen protector. Time will take its toll and it will be worn down after prolonged use. Moreover, the AB glue behind it will also slowly age with the time. So, even if buy  best tempered glass screen protector for your mobile phone, it is advisable  that you update every six months to keep your phone safe and protected.

PACKING ACCESSORIES

Accessories are mainly equipped with alcohol bag, wipe cloth and dust film. Every time you wipe the screen when you find trace of dust these accessories will come handy. These are good for removing dust and dust paste as the keep your screen protector shiny while maintain the longevity of your phone. Although, some high-end brands are equipped with a screen protector installation frame, these accessories are handy for all the time.
