where is using OLED?

Combining innovation and convenience, these transparent OLED solutions can be applied to various forms of public transport.The Transparent OLED for Subway Trains is essentially a glass screen that displays advertisements, news and weather forecasts while maintaining high transparency.

The glass surface uses SPD (Suspended Particle Device) Smart Glass from Israeli materials science company Gauzy - a special toughened glass - in an IGU (Insulated Glass Unit). This gives it the increased strength and durability to withstand strong impacts and vibrations. This screen can replace standard train windows as it also blocks up to 99% of light when SPD is activated. This creates even higher contrast for colour-rich displays.
