SEOUL -- Transparent OLED (organic light-emitting diode) displays produced by LG Display, a major flat panel maker in South Korea, have been used for the windows of subway cars in two Chinese cities, Beijing and Shenzhen, showing passengers traffic information and daily life information such as weather forecasts and news.

Because transparent OLEDs do not need backlights, they can be used for self-driving cars, aircraft, subways and smart buildings. LG Display said it has supplied 55-inch transparent OLED displays for subway car windows in Beijing and Shenzhen.

LG Display promised to expand the supply of transparent OLEDs to major subway stations in cooperation with railway companies and train glass companies in other countries. "The use of transparent displays will become more diverse," LG Display's TV business head Oh Chang-ho said, adding transparent displays could be used in various fields.

LT Display, affiliated with South Korea's LG Group, has established a lineup of premium OLED displays, which are transparent, flexible and rollable. Transparent OLED screens display black content as transparent, allowing designers to overlay digital content such as images, text and video onto real-life objects placed behind the transparent screen.
