"Film" that protects smartphone displays from scratches and dirt.Like the main body case, many people will buy it as a set if you buy a new smartphone.However, even if you want to buy it, there are so many types and you are wondering, "I don't know which one to choose."
Therefore, this time, we introduce general five types of smartphone film.While explaining each characteristic, we will explain the recommended film for each purpose.
There are two main types of smartphone films, "PET" and "glass"
Although it is a number of film products, the materials are mainly divided into two types, "PET" and "glass".
| 保護フィルム | ガラスフィルム | |
|---|---|---|
| 主な素材 | PET（ポリエチレンテレフタレート） | ガラス |
| 傷や衝撃への耐久性 | 爪などによる傷を防ぐが衝撃にはあまり強くない | 衝撃に強く、画面の割れを防ぐ |
| 価格 | ガラスに比べて安価で購入可能 | 保護フィルムよりも高価な製品が多い |
| その他のポイント | ○ フィルムが薄くスマホケースと干渉しにくい△ 薄く柔らかいので貼りづらい | ○ 透明度が高く画面の視認性を損ねない△ フィルムに厚みがあるためスマホケースと干渉することがある |
Films using PET materials are generally called "protective films".PET is an abbreviation for a type of polyester, "Polyethylen Terephthalate," and is a material used in plastic bottles.It protects the screen from small scratches and dirt, such as scratches due to nails.The point is that the step is hard to create even if you put it because the film itself is thin.However, it is basically not so strong for resin.
On the other hand, those using glass are called "glass film".It is more resistant to impact than PET material and prevents the display from cracking.In addition, the transparency of the film is high, so the visibility of the display display is not impaired.On the other hand, it may interfere with the smartphone case because it is slightly thick.
Everyone struggles with smartphone film pasting.Here, we will introduce what you need to stick well and the actual procedure.
What to prepare
First, put the film on the display with the peeling sheet attached, and adjust the position on the top, down, left and right.At this time, it will be easier to match if you use the camera or home button as a guide.Once you have determined the position, fix the film and smartphone with the sticker attached to the product (cellophane tape is also possible).
Use a cleaning cloth or glasses to remove dirt and garbage on the display.Wipe off your fingerprints that are often attached when removing.
Peel off the peeled sheet for about 1/3 and paste it on the display.While peeling off the separation sheet slowly, press the ruler and paste it out to drive out the air.It is OK to use a hard IC card instead of the ruler.
Have you ever seen "surface hardness" or "9H" in product packages and product information?This is a standard pencil hardness specified by JIS, which means "the harder of scratches when you pull the surface with a pencil of a certain hardness."
Like the hardness of the pencil, it is described as "6b", "HB", "6H", etc., and the highest rank is "9H".In other words, if the product information says "surface hardness 9H", it means that it will not be scratched even if you catch it with a 9H hardness pencil.By the way, there is another standard called Mohse hardness for hardness.It is important to note that the hardness of the mineral is a scale, and the standard of strength is very different from pencil hardness.Morse hardness is represented by 1 to 10, and the highest rank "10" is based on the world's hardest substance diamond.
