If you want to say that the mobile phone companion accessories with the highest wear rate, the most consumption and the most security of users, "screen film" is definitely a well-deserved FMCG product under this category. Mobile phone film development has been derived from a number of materials and versions, tempered film, high permeability film, matte film, anti-peeping film, mirror mask, hydrogel film, blue film, etc., even though the screen glass on the mobile phone screen has enough anti-fall and anti-scratching ability, such as Corning Gorilla's latest Corning Gorilla Glass Victu, can make the phone fall at a height of 2 meters to keep the screen from shattering, but consumers still feel that the screen is not broken without film "There is always no sense of security in use, even if there have been various research results and practices that confirm that the use of the mobile phone screen film is not large or even affect the sensitivity and perception of the screen, the psychological comfort of "one more layer of film to save a lot of things" is still far more than the actual needs of the experience.
"Whether the mobile phone should be filmed" The topic we are temporarily pressing the table today, because to say a thousand and ten thousand, the meaning of the birth of the mobile phone film is in the final analysis only two words "protection", it not only protects the mobile phone screen will not be consumed in daily use, can be renewed over time, more importantly, is to protect the users of mobile phones can be at ease, safe use of mobile phones do not have to worry about the moment. Nowadays, the emergence of "anti-peeping film" has further improved the functionality of mobile phone film: the current mobile phone film can not only protect the phone itself, but also protect your privacy. Especially in the subway, bus and other public transportation in these big cities such as Beijing, Shanghai, Guangzhou, and Shenzhen, more and more people choose to paste the "anti-peeping film" for mobile phones, and today we want to discuss the past and present life of the "anti-peeping film" and the advantages and disadvantages that may occur in the process of use.
What is a "peeping film"? What makes "anti-peeping membranes" rise?
In simple terms, the basic principle of "anti-peeping film" is to use the optical principle physically called the "blind effect". "Anti-peeping film" has a voyeuristic layer, is a shutter structure composed of side-by-side arrangement of grating structure, the interval of the grating is generally between 0.02-0.1mm, when the light is directly incident on the anti-peep film, it can be transmitted without hindrance; with the increase of the angle of light incidence (gradually tending to 180 °), the light is gradually blocked by the shutter structure, and the light transmitted is also reduced. Therefore, only the user facing the screen can receive enough light to see the screen, and the bystander at a certain angle with the screen receives a weak light and looks like it is pitch black.
In other words, for the mobile phone to paste a layer of "anti-peeping film", it is equivalent to invisibly to your screen to establish a "small private room", due to the use of special materials and ingenious structural design, the anti-peeping film can eventually make the angle of the mobile phone screen light shooting out of the smaller, can only be shot out in an almost vertical direction, the information displayed on the screen is only you can see, in order to reduce the visual range of the screen and prevent the effect of voyeurism.
So what is the reason for the sudden rise of "anti-peeping film"? Ultimately, it's because of the increasingly compressed "passive social" distance between people. With the development of cities and economies, especially first-tier cities, attracting people from all over the world to pour in, to pursue their own life value, and public transportation as the most economical and efficient way to commute, with the increase in passenger flow capacity, each passenger has the space and commuting area is also decreasing, especially the morning and evening rush hours of commuting and some popular transfer routes, the phenomenon of crowding people next to each other has long been common, in such a crowded scene, want to "glance" at the content on the mobile phone screen next to the person, An action that is so simple that it can even be said to be "inadvertent", coupled with the concentration when playing with the mobile phone, is almost imperceptible. However, it is inadvertently that your "privacy" is likely to be stolen by people with hearts.
For modern people, smart phones have become a "huge gravitational tide of survival, whether it is life or work, the consequences of leaving the track of smart phones are almost unimaginable, for such a long time, we have been accustomed to processing various "data" in life through smart phones, and we are also accustomed to storing these data in smart phones, the small mobile phone that everyone carries on the body every day is actually a huge life database, money, hobbies, relationships, etc. are in it. As the only window for information display, the lit mobile phone screen is undoubtedly like the open door of the "information vault", even if you are watching videos, playing games, chatting WeChat, brushing Weibo or visiting Taobao, these are your "privacy", because the behavior of "using mobile phones" occurs in your private time, and when these things are carried out, I think no one will want to share with strangers around you.
It is undeniable that now everyone in public places is a mobile phone party, with the manufacturers for the screen material, brightness, resolution and viewing angle of the improvement, high-definition screen also to some unscrupulous "voyeurs" have an opportunity. Play a little game and watch a movie get peeked at, but if you're typing in important data like your electronic payment password, how do you make sure they won't be seen by people around you? From time to time, it is locked by the eyes of others, and the feeling of suffocation and personal privacy leakage of being monitored by others has become the root cause of the popularity of today's "anti-peeping film". People choose a voyeuristic membrane, and what they are pursuing is not a kind of mental relaxation.
"Voyeurism" is pro, but there are also drawbacks
The emergence of the anti-peeping film does solve the problem of mobile phone privacy being "peeped" to a certain extent, and even some people call it "the last privacy bottom line of contemporary workers", but it is also because of the "blind effect" and the increased thickness of the structure of the anti-peep film itself, some defects in the use of the anti-peeping film are inevitably exposed at the same time.
It can be seen that the structure of the "anti-peeping film" is very thick
First of all, it is because of the principle of "blocking light" of the anti-peeing film, resulting in insufficient light entering the human eye imaging of the mobile phone screen, coupled with the impact of the light transmission degree caused by the mobile phone film itself, which ultimately reduces the overall brightness of the mobile phone with the anti-peeping film. Long-term use of mobile phones in such low-brightness scenes is extremely prone to eye fatigue. The reduction of light is bound to aggravate this level of fatigue. In addition, it is because of this reason that once the mobile phone is pasted with the anti-peeping film, if you want to achieve the original "standard brightness", you need to pull the brightness of the phone itself up, through the anti-peeping film, the "standard brightness" you see, in fact, may already be the high brightness of the phone itself, long-term use is bound to increase the heat consumption of the mobile phone, shorten the battery life of your mobile phone.
The principle of "optical fingerprint"
In addition, the anti-peeping film may also affect the recognition function of those mobile phones with "screen fingerprints", as well as the insensitive recognition caused by the need to display the two-dimensional code recognition. Especially the current mainstream optical fingerprint recognition scheme, because its principle is to use the refraction and reflection of light, when the finger presses the screen, the OLED screen emits light to illuminate the finger area, and the reflected light that illuminates the fingerprint returns to the sensor close to the screen through the gap of the screen pixels, and the fingerprint image obtained is compared with the image entered for the first time by the mobile phone, and finally the recognition judgment is carried out. The principle property of the anti-peeping film "blocking light" may form an obstacle in this process and eventually lead to insensitive recognition.
The last and most important thing is the lack of current industry standards, resulting in uneven quality of products on the market, some merchants in order to reduce costs, some of the non-passable anti-peeping film into the market, the final damage, undoubtedly or the eyes of "anti-peeping film" users. These are the problems that cannot be ignored and solved in the actual use of the current "anti-peeping film".
The two full laws of the world do not live up to privacy and do not live up to the eyes
At this point in the article, the rise and pros and cons of "anti-peeping film" must have been very clear to everyone. Just like the question of "whether the mobile phone itself needs to be filmed", the question of "whether the anti-peeping film should be promoted" is also a matter of benevolence and wisdom. The weight of privacy and experience in your life determines whether you are willing to endure the small problems that "anti-peeping film" may bring in order not to be snooped on, and of course, the life situation you are in is also one of the decisive factors. But it is still the saying that "existence is reasonable", and now more and more people choose "anti-peeping film", which just shows that it is "useful", not empty to draw snakes.
Behind the rise of the "voyeuristic film" reflects the increasing attention of consumers to their privacy, which is a good thing, so since the market has such a huge demand, can we predict or even "urge" manufacturers to add some technological breakthroughs similar to the privacy and security of the "voyeuristic membrane" in the future in the screen? If it can come true, it is bound to be expected.
Finally read so much about the "peeping film", will you paste the "voyeuristic film" for your mobile phone?
