In early 2019, LG Display started producing 55 transparent OLED TV panels, and these are slowly entering the market - in commercial displays, transportation displays, and perhaps even the consumer market - with Xiaomi’s first consumer transparent OLED TV (although at over $7,000 for a 55 display, it is not really priced at consumer level - and its usability is also not clear).

An OLED display is an emissive display, and some of our readers asked us - how is it possible for a transparent OLED TV to show a black color? Is the image above, released by Xiaomi, a fake?

LG Display announced that it has supplied transparent 55" OLED panels that are installed on subway train windows, in Beijing (Line 6) and Shenzhen (Line 10).

The transparent OLEDs are used to show news, transit maps or other bits of information. LG says that it will aim to supply similar solutions to other subway networks around the world. LG did not detail how many such OLEDs were installed at subway trains in China.

Xiaomi announced what could be the world's first mass-produced transparent TV for the consumer market, the Xiaomi Mi TV LUX Transparent Edition that features a 55" 120Hz WOLED TV panel.

The Mi TV LUX uses Xiaomi's AI Master Smart Engine built around a MediaTek 9650 TV chip, and has support for Dloby Atmos. The Mi TV Lux will start shipping on August 16 in China for 49,999 yuan (around $7,200).

OTI Lumionics announced that its latest ConducTorr Cathode Patterning Material (CPM) materials will start shipping by the end of 2020 to customers, which will use these to create OLED displays with under-the-display camera and face unlock technologies.

OTI says that the first mobile devices using OTI’s CPM materials are expected to ship in 2021. Last month we reported that Visionox will soon start shipping AMOLED displays with an under-the-display camera, it could be the Visionox is OTI's first customer. OTI received a strategic investment from LG recently, which could hint that LG could be OTI's customer as well.

LG Display announced that it is aiming to strike strategic cooperations with companies from industries such as the construction, furniture, and interior design, with an aim to find new application for next-generation OLED displays.

LGD opened a new OLED showroom at LG's Science Park in Magok which allows people to experience different OLED products - including transparent and mirror displays, wallpaper displays and "variable TVs" (not sure what is meant by that, perhaps it is a reference to LG's rollable OLED technology). LGD also released the video you see above showing several "virtual" OLED display demonstrations

OLED producers are looking at under-the-OLED cameras - this is a great technology that could enable complete bezel-less smartphone displays without any pop-up selfie cameras. Samsung, in 2018, announced it is working on several behind-the-OLED sensors, including a camera. But China's Visionox is the first company that actually launched such a technology commercially.

Microsoft recently published an interesting research project (led by Sehoon Lim) that discusses the potential use cases of under-the-OLED camera and its advantages, and also the challenges - with AI technologies that could assist in solving these issues.

Last month Chinese OLED producer Visionox launched an under-the-OLED camera technology, branded as InV See - which enables a selfie camera in a full-screen OLED smartphone. According to new report from China, Visionox has already shipped InV See displays to Huawei and Xiaomi which will launch smartphones with these displays soon.

The report suggests that Visionox started to ship these displays in the second half of 2019 - and these deals were worth over 3.5 billion yuan (around $500 million USD).

Chinese OLED producer Visionox launched a new under-the-OLED camera technology, branded as InV See - which is the world's first such display. The main application for this technology is to enable a selfie camera in a full-screen OLED smartphone.

InV See utilizes a transparent section in the OLED display that allows a camera to be placed behind it. Visionox says that for this technology it developed a new pixel structure, new driver circuits and used new materials.

WiseChip Semiconductor, based in Taiwan, is one of the world's leading PMOLED maker (in fact in 2015 Wisechip said it's the world's second largest). Wisechip is developing next-generation PMOLED displays, including flexible panels, transparent panels and Hyperfluorescence/TADF PMOLEDs.

WiseChip recently announced its first, and the world’s first, Hyperfluorescence display, using TADF materials provided by Kyulux. Can you tell some more about this display and its properties?

This 2.70 128x64 product is adopted mostly in industrial products. The size matters in such market but the main problem was to increase the brightness due to the limited efficiency of the fluorescence emitters. The Hyperfluorescence technology helps to settle the problem and can reach up 2.5 times brighter. It performs much better readability so users do not have to stand right in front of the device. This feature adds to the value of the end product.
