How The Boeing 787 Dreamliner’s Dimmable Windows Work

The Boeing 787 is an innovative and groundbreaking aircraft in so many ways. From its mix of composite materials, fuel-efficiency, and comfortable cabin pressure to its large, electrochroamatic windows. But how exactly does the technology behind that dimmer switch actually work?

The Boeing 787 Dreamliner has the largest windows of any passenger jet. They measure a full 10.7 by 18.4 inches in size. That is in comparison to the second-largest belonging to the 777 at 10 by 15 inches.

But, of course, the Dreamliner's windows are famous not only for their size, which makes the window seat, if possible, an even more coveted commodity, but also for the lack of mechanical blinds.
