Expensive and difficult to use! Put this film on and your phone will be useless

Xiaolei has been complaining about something with Brother Bie for the past two days. Specifically, when I was taking the subway, I saw a strange film on the mobile phones of many girls. I didn't react at first, thinking that the girl was swiping at the black screen. = Looking at it from a different angle, only to find that people have pasted the same type of privacy screen film as the star. In fact, Xiaolei can also understand that the demand for privacy screen is very simple. First, it is dedicated to the office, to prevent the boss from checking posts and colleagues from reporting. The second is to protect personal privacy in public places, making melon eaters feel uncomfortable. = From a functional point of view, privacy screens are indeed useful products. But Xiaolei couldn't help but complain to Brother Bie. The appearance of this thing has made the quality of the mobile phone screen go back ten years... No matter whether your mobile phone screen is Samsung or Huaxing, 4K or 2K, whether the peak brightness can exceed 1000 nits, All are clouds. =When the privacy screen film is stuck on, it means that the screen is sealed and the brilliance of the whole body is swallowed up by the darkness. And this is just one of the side effects of putting on a privacy screen. Taking advantage of these two days #privacy film hurts eyes# has been on the top of the trending search. Xiaolei finally had the courage to talk to everyone about the principles and hazards of privacy screen films... Yes... I wouldn't dare to talk about it at ordinary times. First of all, I will tell the conclusion to the friends who do not want to read the article. In the absence of confidentiality and just need, it is strongly recommended that you do not buy a privacy screen to use. Because for most users, it is a profit and a lot of harm. It is estimated that many friends have seen blinds, which have a long history and originated in China. Generally, it is more common in offices, which can not only shade, but also ventilate. The moving picture is from SOOGIF. To say it, the realization principle of the privacy screen is similar to that of the blinds. It uses ultra-fine shutter optical technology, which is equivalent to shrinking the shutter by N times and putting it in the mobile phone film. In this way, at a certain angle, the privacy film is impervious to light, and sticking it on the screen has become an essential artifact for fishing experts. But everyone knows that even the shutters themselves cannot achieve 100% light transmission. The same is true for the privacy screen film. Compared with the ordinary mobile phone film, the light transmittance on the front is also much worse. Some people may think that it is enough to see the words clearly when viewed from the front, but the effect is that others see the black screen. But how to say, the effect of the privacy screen is achieved, but it will also lose a lot. The most intuitive is the weakening of the brightness of the mobile phone. The light transmittance of ordinary transparent soft film can reach more than 90%, which will basically not affect the brightness of the mobile phone. The cheaper privacy film on the market has a light transmittance of only 30%-50%. Just look at the privacy film I bought today, the bright yellow background on the back is just turned dark yellow by the privacy screen. This will undoubtedly lead to the loss of the brightness of the mobile phone screen, usually 50% brightness is enough for daily use. However, after attaching the privacy screen film, it may be full of brightness outdoors, and the screen may feel dim. The brightness is deliberately increased to use, and the power consumption and heat have to be pulled up, which is not worth the loss. Secondly, because the light transmittance and viewing angle are affected, after the privacy screen film is attached, the screen display fineness will also drop a lot. The ultra-high viewing angle 2K screen custom-made by mobile phone manufacturers was instantly downgraded to 720P E5 material enhanced frosted glass. Originally, I could play with my phone on its side, but after attaching that thing, I could only force myself to keep a certain angle to play with my phone. Don't ask why. If you tilt a little bit, the upper half of the text is directly blurred by three times. Have you considered the feeling of your eyes... If you tilt a little bit, the ghosting will be corrected. It's the display effect with its own mask, which makes me uncomfortable... You said, my mobile phone is still Samsung's E4 2K screen, and the brightness and fineness are at the top level. It is really unnecessary to set the screen strength back ten years just for the effect of a privacy screen. If you are still using an off-screen camera phone, it's even more outrageous. The light transmittance of the camera under the screen is not high, and it is even worse after the privacy screen film is attached. Xiaolei did not have a mobile phone under the screen, so he tested it with the iPhone 11. The specific method is to directly cover the front camera of the iPhone 11 with the privacy screen film, and then find the model and press the shutter. This is a finished film with filters from the 1980s, and it doesn't make sense to make a few horror movies. High EQ: simulating CCD retro camera effect Low EQ: pure IQ tax product The world of cameras is still like this. It will only hurt the eyes to see the screen with human eyes through the privacy screen. Many netizens also said that after putting this film on, they felt dizzy after watching it for a long time, and it was completely to prevent themselves and not others. Mobile phones unlocked with fingerprints are even worse. Due to the reduced light transmittance, fingerprint unlocking will also become extremely insensitive. If ah, I mean if there are friends who can really endure the above side effects, there is actually no problem. After all, everyone's ability to adapt and endure is different, and you may get used to it after watching it for a long time. But judging from Xiaolei's experience of playing with a mobile phone with a privacy film on it today, I did feel deeply tortured. I won't say anything that affects the screen display, it's discussed above. The most uncomfortable thing is that it really affects all aspects of my life. When I go to a convenience store to buy things, I open the payment code as usual when paying, but the boss looks at me like a mentally handicapped person, and asks: "Is your phone screen okay? On?" At this moment, I realized that I can no longer scan the code for the boss with my phone at an angle like before the film. The rest of the scenes that need to be scanned are the same, and you must always pay attention to adjusting the angle of the phone. It is no exaggeration to say that the decades of efforts of screen manufacturers have really been ruined by a film. Of course, Xiaolei knows that some small partners have special jobs and have hard requirements for privacy screen properties. In the case of function first, no matter how big the side effects can be tolerated. At this time, you can consider buying a privacy screen with better quality. To put it bluntly, the light transmittance is higher, and the experience of daily use is better. As for the angle of the privacy screen is too narrow, Xiaolei does not recommend buying it. This means that if you tilt it a little, you can't see the phone screen clearly, and it will be more comfortable to buy 30° - 45°. But again, if you don't have special privacy needs, I don't recommend everyone to buy a privacy screen to use. Be kinder to your phone screen and yourself.
