How to judge the tempered glass screen protector you buy without instrument detection?
Most people and clients do not clearly know the differences between tempered glass screen protectors from different suppliers, thinking the products should be the same. In fact, the product of tempered glass screen protector is just simply glass, not complicated, so the cost should be cheaper, you can cut so many pieces from bigger flat glass.
We are trying to help our friends to tell the quality and what the factors decide. There are two situations we will face:
1. Appearance inspection of products without test machines
2. Test machine inspection in Lab
Today, let's talk about situation 1. Appearance inspection of products without test machine. Here are a few tips for you when you get one tempered glass screen protector:
1. Packaging and Accessories
2. Dust or scratch on the glass
3. The touch feeling on the glass surface
4. Automatic exhaust
5. white line
6. Edge absorb dust
7. Thickness of back plate.
-- Packaging and Accessories
Most brand owners are designing a beautiful and conspicuous retail package for promotion. The good package will show more details of installation and product features, what accessories include inside for easy to install the product. You should select the right products you need and balance the cost with the requirement. After you shop or receive the package, you should confirm what the product and accessories has been offered.
While it's a straightforward point to understand, the packaging and accessories are good, when you buy a product, it's still easy to embed the idea to your head the product is good, to ignore the details.
-- Dust or scratch on the glass
After you open the package of screen protectors, you will find the product, you should check the appearance of tempered glass/screen protectors, see if there is any dust or scratch on the top release sheet, backplate, and screen protectors themselves. Sure, any dust or scratch on the top release sheet and backplate, will not affect the product installation, if there is dust on between the glue sheet and back release sheet/backplate, there are bubbles after adhesive on mobile screen
--The touch feeling on the glass surface
On the glass surface, we always want to get a smooth feeling like sliding on a mirror. We will spend a lot of time touching mobile phones every day, and we will be on different occasions. Our fingers also have different stains or sweat stains. You find that we are easy to leave fingerprints on smooth objects, such as dark stainless steel, sperm, monitor, etc. when our fingers slide, it is not smooth. Therefore, we will do AF(anti-fingerprint) coating on the tempered glass screen protector. Each factory will use different quality AF oil, which will lead to the duration and smoothness of AF. The cost of quality AF oil is several times the price of an ordinary one.
When you get the toughened film, without professional equipment, you can slide it with your fingers feel, or use drop water droplets to observe its sliding speed.
-- Automatic exhaust
Another factor that determines the quality of the tempered glass screen protector is the AB glue sheet. When you try to paste the product on the mobile phone, bubbles are easy to appear if you are not skilled. If the bubbles are in the middle, it is difficult to push and make them disappear. If they are on the edge, you only need to press them.
For a good screen protector, when you try to fit an end on the mobile phone, it automatically adsorbs and fits, so that the whole tempered glass fits on the mobile phone without bubbles, and the whole process is very smooth.
Like the picture below: So congratulations, the quality of this tempered glass is good.
-- White line
When you try to paste some suppliers' products, a white line will appear on the edge of the mobile phone. After you press it, it will still exist. There are several original types of white lines: 1. The size of the tempered glass screen protector is larger than the actual mobile phone screen. 2. The AB glue sheet of the tempered glass screen protector is not smooth enough or the cutting is uneven. This means that the supplier did not carefully check before delivery, or they do not think it is a quality problem.
In fact, you can shine a light on the edge before fitting to see if there is any irregularity. Of course, it is difficult for most consumers to find the problem. The problem can be clearly found only after fitting
-- Edge absorbs dust
In daily use, it is common to find that the glass edge absorbs much dust after using for a while, which is also a performance of the poor quality of the tempered glass.
The premium tempered glass will use the quality AB glue sheet, which with adhesive stronger and cut even, sure the size of tempered glass is perfect to fitting mobile screen, those are able to stop dust moving to inside.
