Gentex Corporation announced at CES 2019 that its latest generation of dimmable aircraft windows will be offered as optional content on the new Boeing 777X. EDWs are an electrochromic-based sunlight and heat control solution that eliminates the need for traditional window shades and lessens dependence on AC systems. EDWs allow passengers to selectively darken the aircraft windows as desired while still enabling them to view the scenery outside. The 777X program will be the first to utilize Gentex’s latest EDW technology, capable of eliminating more than 99.999% of the visible light at twice the darkening speed of previous windows. The 777X system will be designed with centralized control, allowing flight crew to set specific lighting scenarios for day or nighttime flight without reaching over passengers to open or close the mechanical shades.
