Topilka is a sick question for many motorists-to drive to "aquarium" is not wanted, but also to pay a fine for not meeting the requirements, no one wants, either. From here, there are all kinds of hiking of the type of detachable tonia or gales on the windows. Another type of tonic that has been gaining popularity lately is the electronic tonia.
There are currently two main types of electronic tonyings.
1. Several layers of liquid crystals are applied to the inner side of the glass, which are subsequently applied to the voltage. When the signal arrives at the crystals, they interact with each other, causing the glass to light. When the current is stopped, the crystals are no more interoperable and the glass is dark again. This glass is called "smart glass" or "smart glass".
2. Special film is made on the ordinary glass pane. The principle of such a film on the glazing is no different from that of mirror-shading mirrors. The electrochemical layer is connected to the onboard power grid and changes its transparency under the influence of current.
The first technique is more technologically, but the glass with the LCD is very expensive, and its installation and connection should only be performed by professionals. You can buy and install the tape with an electrochrome layer yourself, all installation and installation instructions are available in the kit.
The peculiarity of the electronic tonia is that the degree of insemination may be adjustable manually. If the street lighting is insufficient and the driver wants to keep the glass tinted, he can feed and blackout them. To this end, the electronic tonnage has a special remote control (the most expensive options can also be specified in the onboard computer).
