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:
China-based Visionox demonstrated many OLED displays and new technologies at Display Week 2023.
So first up, we have some rollable and foldable OLEDs. You can see some impressive looking such flexible OLEDs in the video above, and Visionox featured many such displays at their booth.
LG Display demonstrated several exciting OLED display prototypes at Display Week 2023.
First up was the company's 77" 8K Meta (microlens-array) panel - this has been commercialized already, but it is always a wonder to watch this particular display which offers an extraordinary image quality.
So first up Qingyue showed a large transparent segmented PMOLED display, this is the largest PMOLED ever demonstrated at 20.6" in size. It did not detail the transparent level, but this looked very good and was quite impressive.
Taiwan-based AU Optronics (AUO) demonstrated several microLED display prototypes at Display Week 2023, showing the company's focus on microLED display technology as its next-gen platform.
Sample displays include a 13.5" Full-HD 5,000-nits 55% transparent display, a 17.3" transparent panel that includes an embedded LC layer so it turn from 55% transparency to an almost completely opaque display, a 14.5" 2560x1440 foldable laptop display that is based on blue microLEDs with QD color conversion, and more.

LG Display announced a new transparent OLED campaign at Incheon Airport, to show Korea's vibrant culture to travelers from all over the world, and experience Korea's four seasons and folktales.
The installation includes several different displays. One is large wall made from 18 55" OLED displays, a large video wall that "conveys the delicate patterns and colorful hues of Korean traditional folktales while also creating a comfortable openness thanks to its high transparency". Theere are also a total of 14 transparent displays attached to pillars and walls inside Incheon Airport's Tourist Center, utilized to showcase various information such as local times and global weather conditions as well as welcome messages and enchanting videos showing off the "endless beauty of Korean nature".
LG Display has an impressive presence at CES 2023, showing many OLED displays, products and prototypes.
The video above starts with LG's automotive displays, which include new 18" slidable OLEDs and some more OLED and LCD displays.
LG Display is producing 55" transparent OLED panels for some years, mostly targeting signage (commercial) applications. According to a report from Korea, LGD is in talks with LGE regarding the launch of a consumer transparent OLED TV.
Xiaomi's Mi TV Lux Transparent Edition
The reports suggests that LGE does not see a large demand for such a TV, especially in the current market conditions, and if this will happen, it will only happen in 2024. LGE in addition would have to develop new technologies, including using reinforced glass to cover the whole panel.
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.
