Privaatheidsfilm Tegniese beginsel

Let's start with the blinds.

Luike is 'n vensterstyl wat in China ontstaan ​​het. In antieke Chinese geboue is daar vensterdeure wat gebruik is in alle dinastieë, van die strydende state tot die Han-dinastie. Die vertikale stawe word mullions genoem, en die horisontale stawe word horisontale vensters genoem.

Die moderne blindings is egter uitgevind deur Amerikaners, genaamd John Hampson, en het op 21 Augustus 1841 die patent vir die uitvinding verkry. Personeel is oor die algemeen relatief breed en word gewoonlik gebruik vir skaduwee en ventilasie binne en buite.

The shutter curtain wall that more and more people agree with also evolved from the shutter. The shutter curtain wall has many functions and advantages, and it is very beautiful. It is generally used in high-rise buildings. Louvre, a window with shutters installed. Different from venetian blinds. Venetian blinds are similar to curtains, with smaller leaves and can be folded, which are common in our TV or daily life.

The principle of blinds is to block the outside view by the concave and convex direction of the blades. While lighting, it blocks the outside vision from top to bottom. At night, if the convex surface of the blades is indoors, the shadow will not be reflected to the outdoors. The concave-convex surface visually blocks the sight of "spectators".

Die kernbeginsel van die privaatheidsfilm is die microlourver optiese tegnologie, wat voorgestel kan word dat dit die blindings tot tienduisende kere laat krimp, wat beteken dat die streepafstand op die privaatheidsfilm van die selfoon onder 'n mikroskoop van 50 geplaas moet word. -100 keer. Om duidelik te kan sien.

Then the privacy film is the same. Using the principle of blinds, the blinds are placed in the screen layer as a "secret structure layer", and the wide viewing angle of the screen is changed to a narrow viewing angle through the light angle control, and the grating structure arranged side by side ( Blinds), so the light cannot be reflected back to the screen through the screen at a certain angle, so as to achieve the effect of the privacy screen, reduce the display angle of the screen, in simple terms, people around you will not be able to see your screen clearly Content, the name of privacy protection comes from this.

Sal privaatheidsfilters newe-effekte hê?

I have seen that many people have doubts about the privacy film. Does it really affect the vision? Because after the privacy film is attached, the brightness of the mobile phone screen is passively reduced, but so far I haven't seen any data to prove this statement. It is recommended to brighten the screen brightness appropriately when using the mobile phone (30% higher than the original brightness).

However, if you have serious visual impairment in your eyes, or often have uncomfortable eyes, such as dryness and fatigue, try not to use privacy filters.

How to choose privacy film?

Of course, privacy films are also divided into advantages and disadvantages. The first requirement of a good privacy film is to have a good privacy effect and a high light transmittance.

Die anti-piep-effek hou verband met die kijkhoek. Hoe kleiner die kijkhoek, hoe beter is die anti-piep-effek. Nou het die nuwe anti-piep-film 'n kijkhoek van minder as 30 °, wat beteken dat die anti-piep-reeks uitgebrei word, wat persoonlike privaatheid beter kan beskerm.
