How to safely read Habr at work using our information protection screens
Good afternoon, dear Habrausers!
In this article, we will talk about films that allow you to remain confident that no one except you will see information from your screen.
We will analyze the relevance of the problem with spying and tell you how we implemented the technology from the technical side.
PS No more TM and.
In situations:
rather unpleasant when a person nearby monitors activities on the screen.
We even have a very funny simulation of situations:
In a cafe
In the bus
American researchers have established a direct relationship between how comfortable it is for a person to work at a computer and its performance. Given the urgency of the problem, we created a solution to provide visual protection of information and increase employee productivity.
In Russia, the implementation of a policy for the protection of visual information in the professional sphere is only just beginning. Basically, an assessment of the potential damage from the loss of visual data and ideas for their protection come from the West.
For example, in our company, and in many others, there is a special policy that speaks of the employee’s obligation not to divulge corporate information and ensure its protection with the help of tools that prevent the reading of visual data from monitors while working in public places.
In the banking sector, in the medical industry, in government, in offices - the protection of visual information is an integral part of ensuring security.
Comparison
No one needs to explain why information protection is needed if someone stands behind a person who enters a password at an ATM and checks the balance on the account. Yes, there are ATMs that print the balance on the check, but there are also those that display a number on the screen. Many banking machines already use technology to protect visual data, as this is the most obvious application.
There is no need to even talk about the relevance of this solution in an open-space office.
There is light from the screen, but no image.
From a technical point of view, the technology is similar to window blinds, only it is all “wrapped” in optical films and reduced to 0.8 mm thick. In the figure below, the sectional information protection screen.
In fact, this is a thin and flexible black film that is placed on the screen in adhesive mounts. It can be quickly removed and shown to colleagues if needed. Or just before going on a business trip, install a screen for comfortable work on the go.
This material is called ALCF - Vikuiti Advanced Light Control Film Anti-glare 60 ° and is an optical film that limits the amount of light passing at angles greater than 60 degrees.
The external material is polycarbonate, the layer with partitions consists of acrylic resin and soot.
The observation angle is equal to the sum of the angles (0 and f), pending from the direction of maximum transmission, at which only 5% of the maximum transmission of light passes through the film.
Partition angle: 0 ° ± 2 °
Observation angle: 60 ° ± 4 °
Color:
Color coordinate X according to classification 1931 CIE: 0.317 ± 0.02
Color coordinate Y according to classification 1931 CIE: 0.335 ± 0.02
ALCF tests are carried out under the following conditions on a loose film. Under these conditions, no significant changes occur.
Side view:
We did not specifically fix the film so that the brightness of the screen was visible.

By the way, in Russia the Federal Law of the Russian Federation of July 27, 2006 No. 152-FZ “On Personal Data” (the current version of 04/19/2013) is in force, which regulates the rules for the treatment and protection of confidential information.

The screen also serves to physically protect the display from scratches and damage - the polycarbonate coating is quite durable.
There are formats for any monitors and laptops, even a specialized series for Apple computers here .
In our portfolio, you can find films for protecting information on displays of mobile devices. It differs from the computer only in that for smartphones a film with an adhesive layer is glued in the same way as a normal protective film and performs the same functions, including protecting information.
In addition to information protection films, there are transparent protective films: an ultra-transparent series for increasing the brightness of the display, anti-glare series and anti-fingerprint films.
The optical division of our company originally produced films for the production of displays: an increase in brightness, contrast, as well as polarizing and reflective films.
The main ideas of optical films are improving the energy efficiency of displays, image quality and viewing angle, reducing the weight and thickness of displays.
If you disassemble the screen of a TV, monitor or phone, you will surely find our optical films.
In the evening shootentitled “There is no time to explain, tomorrow the article on the Habr!” Our employees participated, for which many thanks to them!
The same professional optical filters and adhesives are used for "civilian" protective films for phones.

About the idea of the product.

And where else is it applied?

So how does it work?
There is light from the screen, but no image.
From a technical point of view, the technology is similar to window blinds, only it is all “wrapped” in optical films and reduced to 0.8 mm thick. In the figure below, the sectional information protection screen.

| Paragraph | Method |
| Partition Angle | Photometer: An electro-optical photometer with a photometric filter and an aperture with a 2.5-inch field of view Light source: 50 W halogen lamp - Oriel 50W Quartz Tungsten Halogen Lamp with a stabilized power source and diffuser. Procedure: Turn the sample to the position at which the photometer will show maximum transmittance. Record the appropriate angle of the partitions. |
| Viewing angle | Photometer: An electro-optical photometer with a photometric filter and an aperture with a 2.5-inch field of view Light source: 50 W halogen lamp - Oriel 50W Quartz Tungsten Halogen Lamp with a stabilized power source and diffuser. Procedure: Multiply the maximum transmittance obtained by measuring at an angle of observation by 0.05. Turn the sample left or right until the calculated value is obtained on the photometer. Write down the corner. Turn the sample in the opposite direction until the calculated value is obtained on the photometer. Write down the corner. The sum of the two recorded angles is equal to the angle of observation. |
| Colour | Light source: D65 Measurement: Transmission Equipment: BYK Gardner Colorsphere Procedure: Measure the X and Y color coordinates according to the 1931 CIE classification. |
ALCF tests are carried out under the following conditions on a loose film. Under these conditions, no significant changes occur.
| Test | Condition |
| Moisture resistance | 70 ° C, relative humidity 95%, 48 hours |
| Heat resistance | 120 ° C for 24 hours |
| Heatstroke | -35 ° to 85 ° C, 10 full cycles of 11 hours each |
