In February 2019 LG Display started producing its 55" FHD 38% transparent commercial OLED displays, and the company recently announced several projects that utilize its 55" transparent OLED displays - on subway train windows in China, in Seoul's Trade Tower parking and in an unmanned coffee shop in Singapore.

Cho Min-woo, head of LG Display’s Transparent OLED business, says that LG's is just "sowing seeds" in this market, which it expects to grow quickly. In fact, LG Display, together with a global consulting firm, looked into the potential of transparent OLED displays, and estimated that the market will grow to around $8.5 billion in the next 10 years.

The main market for LG's transparent OLEDs is commercial signage and advertisements (over 70% of current sales). But LG is looking to expand its reach into transportation and architecture, among other markets.

During the recently held International Motor Show (IAA) 2021, in Germany, LGD introduced transparent OLEDs for rail carriages to the European market for the first time. Together with smart glass developer Gauzy LGD showcased novel 55-inch FHD transparent OLEDs.

LGD explains that trains and subways generally have limited spots to display information – the largest unused space would be the carriage windows - into which transparent OLEDs fit perfectly. LG's OLEDs "provide additional information and convenience while maintaining the natural openness of the window".


LG Display also aims to introduce transparent OLEDs on tourist buses, self-driving cars, and ships.
