Korea Approves the Use of Transparent Windows on High-Speed Trains
​

LG’s transparent OLED secured final Korean state approval for windows in high-speed trains after they were first introduced in other countries like China. LG's 55-inch OLED train window with a transparency of 40 percent can display operation information, advertisements and entertainment content. China has already adopted transparent OLED displays in Beijing, Shenzhen and Fuzhou, while Russia and Japan are pushing for the introduction of window advertising. The panel has been strengthened against impact and vibration by applying special tempered glass to suit high-speed trains.

In South Korea, luminous window ads on the exterior of transportation are prohibited due to comprehensive regulations, so the introduction of subway ads using transparent OLEDs has been delayed. In a policy change announced on August 30, the Office for Government Policy Coordination selected cases for regulatory innovation and approved an advertising method using the new technology in subways.

The controlling office made it clear that that "subway advertisements using transparent OLED displays are not subject to regulation." The decision came two months after LG Display showcased its transparent OLED window at a railroad technology trade fair in the southern port city of Busan. LG officials suggest transparent OLED can be widely used in various places such as hotel check-in counters, museums, subways, stores, self-driving cars and aircraft cabin interiors because they do not need backlights.
