LG Display announced that Korea’s newly launched Great Train eXpress (GTX) subway service has installed the company’s 55″ transparent OLED displays in the cabin windows.
This is the first subway service in Korea to install transparent OLEDs (similar projects have already been deployed in China, Russia, and Japan). The idea is that the OLEDs create a “comfortable and smart on-board experience by displaying varied content”. LGD initally installed 16 OLED displays on a single train with eight cars running on the inaugural GTX line between Suseo and Dongtan. Going forward, the GTX plans to install OLED panels in all of its trains.
LGD further says that special tempered glass has been used to make the Transparent OLEDs more resistant to shocks and vibrations compared to the past so that they can operate stably even on trains running at speeds of more than 150 kph, and they have passed the standard Korean railway test.
