Presented glass with electronic dimming from Boeing Dreamliner


Previously, electrochromic glass panels barely penetrated the automotive industry, but it will change soon.

To move the louvers up or down in the plane or in the back seat of your Uber Black – is the last century. Nowadays, the pressing can be almost completely electronic way to darken any of these glasses. Global automotive supplier Gentex electrochromic window offers powerful for the Boeing 787 Dreamliner, and now the new glass will appear on the 777 and some Airbus aircraft. While the standard technology used for many years for electric dimming rear view mirrors, and even appeared in limited form in the roof hatches of the Mercedes-Benz display at CES Gentex 2020 included several new elements this technology in car Windows. Here are a few options that this magical technology can get into new cars in the coming years:

This application faces the fewest obstacles, and, therefore, may be the first that do will find its place in the market, because there are no rules to haze the hatches. In addition, Mercedes has for years been offering anti-dazzle, anti-dazzle glass roof panels (supplied by another company and sold under the name “Magic Sky Control”).


The rules allow the upper part of the windshield was darker than the rest of the glass, so that the band of the visor with a variable tint, electrochromic eg hatches with varying degrees of shade will also not encounter serious legal obstacles. However, it will still need some way to implement it. The challenge here is to create invisible boundaries electrochromic and clean areas of the frontal windshield.

The rules around the rest of the car Windows, and for side and rear Windows still stricter. This situation poses Gentex engineers a new challenge: the increase of light transmission of the electrochromic layers. These days, even in the off state, these panels are capable of transmitting only 55 % of the incident light that did not meet the 70% minimum requirement of the National administration of road safety.

Gentex also began the manufacture of smoke detectors, and one of its technical displays at the CES show this strong side: a smoke detector that can be built into the HVAC duct machine can pick up traces of tobacco smoke or vapor products and to notify the vehicle owner or operator’s fleet.
