OLED technology enables thin, efficient and bright displays and lighting panels. OLEDs are currently used in many mobile devices, some TVs and lighting fixtures. OLED displays offer a better image quality compared to LCD or Plasma displays - and can also be made flexible and transparent.
Transparent OLED displays
Several companies develop transparent OLED (also referred to as T-OLED) technologies. While there's no inherent technology barrier towards transparent OLED displays, finding actual applications for such displays is not easy.
As of 2021, LG Display is producing 55-inch transparent OLED panels (used mostly in signage and commercial settings) while other companies produce small (around 1-2 inch in size) transparent PMOLED display. In April 2013 we posted a review of Futaba's 2" 160x128 transparent PMOLED panel - which could be an interesting read even if this specific display is no longer in production.
Transparent OLED Lighting
OLED technology can be used to make lighting panels - these are thin, area-lit and efficient lighting panels, that can be made transparent. Unlike displays, transparent OLED lighting panels have more immediate applications (embedded in windows, for example). In April 2012 we posted our hands-on review with a transparent Tabola OLED lighting panel sample. As the OLED lighting market in general is still at an early stage, we do not see actual adoption and production of transparent OLED lighting.

The latest transparent OLED news:
K-Pop powerhouse SM Brand Marketing has opened a new flagship store in Seoul, called KWANGYA. Teaming up with LG Display, SM installed 33 transparent OLED panels, spread out across the entire floor to show videos and images from KWANGYA's universe.
Various K-Pop items (autographed albums, light sticks, etc) have been placed under the transparent displays to match the videos.
Canada-based OTI Lumionics have raised $55 million in its latest round. This round included several strategic and financical backers - including LG Technology Ventures, Samsung Ventures, UDC Ventures, Anzu Partners and more.
OTI says it is close to commercialization of its technology and materials, but the company is still some years before this will reach products. Towards the end of 2022 OTI started shipping its 2nd-gen ConducTorr Cathode Patterning Materials (CPM) to customers, but perhaps these were only sample shipments. OTI materials are used to create OLED displays with under-the-display camera and face unlock technologies.
LG Display has showcased its latest transparent OLED solutions for mobility applications at InnoTrans 2022, a trade fair for transport technology.
LGD shows its 55" 38% transparency FHD transparent displays, that actually has been adopted for subway windows before. Interestingly, LGD has also unveiled a new transparent OLED display - a smaller 30" display that offers higher transparency - 45%. You can see both of these displays in the video above.
LG Display has equipped a tour bus in Korea's Suwon town with transparent OLED displays, to enable a sort of augmented-reality tour that overlays historic images that simulate life in Suwon in 1795.
LGD says that "historical figures come to life as animated scenes match up with the fortress walls to show them in their original setting. You get to sense what this city would have looked like centuries ago, and how people in traditional dress would have lived and celebrated major events. Thereâ€™s even a demonstration of old technologies during the tour, with text in Korean and English to guide you along".
Last week Seoul hosted the K-Display 2022 exhibition, Korea's largest display industry event, and both Samsung and LG demonstrated their latest display innovations.
In the video above, you can see LG's 97" OLED.EX CSO panel and its 55" transparent OLED panels. Samsung was showing its latest foldable OLED panels (that can be folded twice) and its QD-OLED panels.
LG Display's VP Kang Won-Seok says that the company is working on several new panels and technologies, which it plans to announce soon.
First up is a 20-inch OLED, for applications in personal devices. This panel will be demonstrated before the end of the year. It is not clear whether LGD will adopt its WOLED technology or its RGB technology for such panels.
LG Display announced its financial results for Q2 2022, with a net loss of around $290 million (down from a profit of around $320 million a year ago) as the company's sales dropped 14.6%.
LGD says that the loss was due to weak demand for TV and IT displays, coupled with supply chain issues and the lockdowns in China. LGD says it plans to continue and reduce its LCD TV business, and to stop LCD production in Korea in 2023, earlier than expected before. The company will focus instead on OLED TV panels and the automotive market, and will aim to open up new markets for transparent and gaming OLEDs.

LG Display, together with British design magazine Dezeen recently launched the 2nd OLED Go! Design competition. LGD announced the winner of this year's competition, the Caelum desk, designed by Turkish designer Cagatay Afsar.
Caelum integrates a 27-inch transparent OLED displays into the desk partition, eliminating the need for a separate monitor to free up desk real estate and reduce household clutter. When not in use, the display can switch to its transparent mode as to seamlessly blend in with the room’s décor.
LG Display has deployed 38 55" transparent OLED displays at a new bakery in Korea. This is a "futuristic" flagship branch of Korea-based Paris Baguette, in Pangyo. LG says that in this new bakery, new products and services can be experienced first, and this goes in line with the adoption of the transparent screens.
This is the largest ever transparent OLED installation, where these OLEDs are used to create a giant digital signage system. The screens are used in the store's entrance, as a smart partition between the baking station and the store, as transparent art wall, and also as transparent signage on the windows, on the bread stand.
