LG Display showcases transparent OLEDs

South Korea’s LG Display (LGD) is exhibiting its latest designs, including its 55-inch transparent displays, at the International Motor Show in Munich.

LGD is collaborating with ‘smart glass’ tech company Gauzy and will let visitors experience the many entertainment and informative experiences that its 55-inch Transparent OLED panels can bring public transportation services when replacing their vehicle windows. Moreover, with its transparent OLED technology, the company will cooperate with Gauzy to replace windows in various types of transportation vehicles to enable smart and dynamic transparent displays.

LG Display unveiled two 55-inch Transparent OLED displays. One is equipped with IGU (Insulated Glass Unit) technology, a special tempered glass that provides the strength to handle impact and vibration. The second product is laminated with Gauzy’s SPD (Suspended Particle Device) Smart Glass technology, which enables high contrast ratios, thereby making the OLED even more adaptable to bright environments and shifting light conditions.

While SPD is on, a Transparent OLED screen can deliver clear visual content to show what is behind the display, increasing its potential for future Head-Up displays while making it a viable replacement for all greenhouse glazing where both information and a view of the outside is desired.

LGD says that to create greater contrast when direct light hits while also providing shade for passengers to enhance the safe and comfortable travelling experience, SPD technology dims the Transparent OLED panel to any desired opacity, blocking up to 99 per cent of light and allowing high contrast and rich colours through day and night. With outstanding application potential in both automotive and built environments, this newly-unveiled Transparent OLED presents the future of signage to all kinds of settings.

Eyal Peso, Gauzy CEO, adds: “The future of displays is transparent, and it’s here now. The ability to make any window active, multifunctional, and the ability to provide both visual and thermal comfort alongside communication is one of Gauzy’s core goals. By adding our LCG smart glass technologies to glass and other technologies like transparent OLED’s with SPD by LG Display, together, we are setting a new standard in signage.”

Last year, LG Display began replacing subway train windows in Beijing and Shenzhen, China, with the world’s first Transparent OLED panels for transportation, which now provide commuters in these cities with useful travel information such as subway times, transfer information and flight schedules, on top of other daily information like real-time weather forecasts and news. The company also broke new ground by extending these futuristic displays to Japan’s overground trains, which helped the East Japan Railway Company receive the Digital Signage Consortium award for outstanding performance.

LG Display’s Transparent OLED is already being utilised in various areas. The company most recently collaborated with South Korea’s Kakao Mobility to install Transparent OLED panels in the parking lot of Seoul’s Trade Tower. With the instalment of these displays, these unique panels add a vibrant and futuristic feel to an otherwise ordinary parking garage. Transparent OLED not only sports innovative technology to display content clearly but also a high level of transparency that makes striking spatial interior effects possible.
