Last week It was reported that at this CES, the foreign manufacturer Amzer displayed a model named ShatterProof's mobile phone screen protector With this film on your mobile phone, you can't even hold your mobile phone screen with an electric drill. You just have to surrender. In addition, the Internet has posted a powerful video of using an electric drill to drill your mobile phone screen. The video is very interesting. Who would take a tough electric drill that can only be used on the construction site to make their own machine. This is very attractive. The problem is that after the electric drill is operated on the mobile phone screen, the screen is undamaged, but the trace of the electric drill is left on the film of the mobile phone screen, to prove the strength of the protective film. This is also a visual impact point. But Xiaobian is still here《 Is the hard resistance of the mobile phone screen to the impact of the electric drill all due to the mobile phone explosion-proof membrane? 》In this article, several questions are raised. Is it really the result of the film? Today, I will try to answer my doubts.
First, today's test object presentation:
The protagonist of today's test: electric drill
The type of drill was also introduced in the last article. This time, after getting the electric drill and drill from the mail order, the editor found that the drill was really dull.
Love to play computer games Royal screen role: original iPad touch screen
Temporary supporting actor: Liangtai Xiaomi 2
Well, Xiao Bian began to do experiments. To be on the safe side, Xiao Bian still didn't dare to go directly to the real machine, so the next step was the confrontation between the electric drill and the iPad touch screen. First, he stuck a mobile phone screen protective film on the original iPad screen. Xiao Bian bought it on Taobao for 80 cents a piece, to see if it could play the role of a protective film worth hundreds of dollars!
You can see that the iPad screen electric drill has been tested on the parts with and without protective film. We can see that where the protective film is affixed, only the film has been left some traces by the electric drill. When the protective film is opened, the whole screen can not see any traces of damage. Without the protection of the protective film, the iPad screen can still tenaciously resist the drill bit of the electric drill, and the drill bit cannot crack it or leave traces on its screen.
With such experimental background, Xiaobian will feel much more at ease, and then come the fake millet 2:
As you can see from the video, the mobile screen of the fake Xiaomi 2 is as strong as the original iPad screen under the test of the electric drill. After being destroyed by the electric drill, the mobile screen is still as beautiful as new. It seems that the fake products are not completely rubbish. It is just necessary to select a relatively good product from a large number of fake products.
From the two videos above, we can see that even if there is no mobile phone film, there is no problem for the mobile phone screen to fight against the electric drill. Is it the charm of the mobile phone screen that makes the electric drill become flexible? Of course not. At present, the most scientific explanation is that the hardness of the surface glass of the mobile phone screen is higher than that of the electric drill bit.
Xiao Bian searched the information and found that the Mohs hardness of the mobile phone glass screen is about 6.5, and the hardness of some strengthened glass screens can reach 7, which is equivalent to the hardness of sand (quartz). The Mohs hardness of the steel used for making ordinary tools and drills is about 5.5, so it cannot damage the mobile phone screen with higher hardness.
At the end of the story, the editor said that it was necessary to film the screen to protect his beloved machine, but it was unnecessary to spend too much money. After all, film pasting is a waste product, and the cost of general film pasting is very low, but it varies from a few cents to a few dollars. The film pasting with a price of up to several hundred yuan appears in the market, which takes advantage of everyone's desire to better protect the machine. In addition, demonstrations like "electric drill and glass drill" that seem to be against our attempts may make more people willing to pay hundreds of dollars. Through this experiment, we hope that you can correctly understand the mobile phone screen and film, and not be confused by those "concepts".
