The prices of safety glass starts from 100 and ends at around 3-4 thousand. They have a special set of characteristics – hardness, oleophobic coating, concrete filter, etc. What does it all mean and how to choose to display reliable protection? Here is a brief guide that will help you deal with the most popular questions about safety glasses.
does the smartphone protective glass?
In the manufacture of many of the smartphones today use double-strength glass Gorilla Glass, Dragontrail, etc. It can cover the front and back cover. Its mission – to protect device from minor damages, but relying on this protection is not necessary. Keys, sand, debris in the pocket and the bag, the habit of putting the phone on a table face down – all the reasons that appear on the screen of the ugly scuffs and scratches. If the smartphone is dropped, the touchscreen and display broken. Replace the display module will cost several thousands (in the case of an iPhone the price of the repair can reach up to 15 000).
The protective glass is also not eternal. It can be scratched, and cracking. But agree, nice to know that crashed itself is not an expensive screen, but only the protection that at any time you can remove and replace with new.
A protective film and tempered glass – what's the difference?
Stores предлагают два вида защитных покрытий – прозрачную пленку и закаленное стекло.
The polymer film appeared before the hardened glass. They are a thin layer of plastic. It must be applied with extreme caution, as it folds easily and becomes unusable. Film is quite inexpensive – from 50 roubles often included are two pieces. It will protect the screen surface from scratches and scuffs, but the impact will not be saved.
Tempered glass is more expensive, and harder to damage it. On average, its purchase costs 600-800 rubles. In principle, it is not so expensive accessory for a smartphone at the cost of 20+ thousand. Tempered glass is more resistant to mechanical damage than film. If the smartphone falls, it will take a hit, and in addition will protect the display from moisture.
Of these two options is the most reasonable buy would be tempered glass. You give him more money, but in return receive a high level of protection.
What is tempered glass?
In fact it is ordinary glass processed at high temperatures with chemical compounds. After heating to several hundred degrees, the glass is subjected to rapid cooling, resulting in a product of high strength.
Tempered glass for smartphone has a multilayer structure. To stick it simple, this task anyone can make it at home. In the package with him will be all you need two wipes for screen cleaning (wet and dry), some stickers and instruction.
Can tempered glass be bent?
When you pick tempered glass in hand, you will feel that it is not too hard: stiff, springy, but quickly returns to its original shape. Just want to ask: as well, it's glass, why is it bent?
Unbelievable but true: the glass is flexible.
Screens iPhone, iPad, Android smartphone and even Nintendo Switch have some stock of plasticity. Site staff 6to5Mac in one of his videos showed it. Of course, we do not call to find out how the screen of your gadget flexible, nothing good is not over. On the contrary, think about how it can protect.
Is not, each glass is able to bend in a way that is noticeable to the human eye. Glasses, coffee tables, decor items made of thick glass and bend their hands will not work. Tempered glass for smartphone primarily thin, thinner than a millimeter, so flexibility is not a defect, but a normal property.
What is 9H? This is an important parameter?
You have protective glasses has a unique set of technical properties. Talk about the most important.
Is not an indicator of hardness on the Mohs scale, as it may seem. 9H hardness means that the product cannot be scratched with a pencil of 9H, the most stringent standard pencils. The truth is, it's not a very reliable test, but it is easily reproduced in the home, confirming that the glass meets the stated level of strength.
To be honest, this is the only parameter that matters when choosing tempered glass for your smartphone. Unlike polymer protective films, glass easily collects fingerprints. Not deadly, but unpleasant, and to carry with you everywhere a microfiber cloth is also not very convenient. From the prints to protect the oleophobic coating. This thin oil layer with a grease repellent properties. If it is, the glass will remain significantly less spots. But we must remember that the oleophobic coating will eventually wear off. Usually it takes 6-8 months.
Protection military standard
Just a marketing ploy, nothing more. Any glass will break if you apply the right force, and military standards do not play here an important role.
Private filter (anti-spyware coverage)
Special layer that hides the information on the display, if viewed from the side at an angle of 30-40 degrees. This chip is for those who are very much worried about their privacy. If you want to take this glass, remember: often it adversely affects the clarity of the image.
a Matte finish
A protective glass with a matte finish are not too common and are mostly popular for smartphones. To buy it or not depends on your personal preference. You do not like shiny glossy screen, stick it on glass with a matte finish, and the extra glare will not irritate the eyes.
I pasted protective glass. I don't have anything to worry about?
A protective glass covers the screen only, it does not surrounds the smartphone like a protective cover. When the gadget will hit the corner, the force of the blow through the casing will be transmitted to the display, and then damage is inevitable. And this, according to the Wirecutter website, the most common type of fall. It may happen that the protective glass will be intact, but the screen itself is covered with a network of cracks.
But if the smartphone will roll on the floor flat, then in the first turn crash protection. It will save from scratches and keys in the bag, and many other troubles.
The right combination of tempered glass includes all the features of the display (rounded edges, frames, cutouts, dactyloscopy, etc.), it does not reduce the sensitivity of the touchscreen and does not prevent to use the on-screen fingerprint scanner. However, the protective glass is not a replacement of the case and in any case no guarantee that the smartphone will not receive any injuries in the fall. This is one way to extend the life of the gadget and to avoid costly repairs.
