Will the 777X have dimmable windows?
Boeing is set to offer electronically dimmable windows (EDWs) on its upcoming 777X aircraft. This follows the plane manufacturer’s implementation of similar panels on its 787 Dreamliners.

Airplane windows were made round for safety “Rounded corners are designed to help evenly distribute the pressure exerted on the window, reducing the likelihood of a window cracking under changing air pressure,” Orlando explains.
How do plane windows dim?
Electrical current through gel However, the panes of the Dreamliner’s windows, manufactured by a company called Gentex, have a layer of gel in between them. When an electrical current is applied to the gel, it causes a chemical reaction that alters its opacity. The higher the voltage, the darker the gel becomes.
What plane is bigger 787 or 777?
The Boeing 777 series is generally larger than the 787 and thus can carry more passengers.
How do dimmable windows work on a Boeing 787?

How do Dreamliner’s dimmable windows work?
