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.

The actual OLED materials are transparent, and indeed it's possible to fabricate transparent OLEDs (sometimes refereed to as T-OLEDs). Many OLED makers are developing transparent OLEDs, and we have seen prototypes up to 55" in size (the largest and most advanced transparent OLED prototypes have been demonstrated by Samsung and LG). Samsung did intend to start producing 55" transparent OLEDs in 2016, but later decided to stop that program.

Small (up to 2.4" in size) transparent OLED displays have been in the market for several years - but applications have been few and far between. Both Neoview Kolon and Futaba used to produce such displays (in April 2013 we posted a review of Futaba's 2" 160x128 transparent PMOLED panel - but both companies stopped producing these OLEDs and currently it is difficult to acquire non-custom transparent OLEDs.

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.

A Q&A with Dr. York Tsai, Wisechip's Vice President of R&D

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.

Here are LGD's transparent OLEDs used in MBC Korea Elections broadcast

A few days ago we reported that MBC studio in Korea will use LGD transparent OLED displays in its 2020 Korean Election broadcast. The broadcast took place yesterday, and included six such T-OLED displays:

LG Display's transparent OLEDs feature a brightness of 150 cd/m2 (peak white brightness of 400 cd/m2) and a transparency of 38% and a color gamut of 120% NTSC. The display can optionally include touch functionality.

LG Display announced that MBC Studio will adopt the company's transparent OLED screens in its Korean 2020 election result broadcast tomorrow (April 15). In February 2019 LG Display started producing its 55" FHD transparent commercial OLED displays, and LGD says that this is the first time its transparent OLEDs will be featured in a high rating broadcast (but this isn't so - see note below on DR1's June 2019 broadcast).

LGD to showcase new automotive, aerospace and consumer OLED technologies at CES 2020

LG Display announced that it will demonstrate several new OLED technologies at CES 2020 in Las Vegas next week (January 7-10).

LGD aerospace OLED demonstrator CES 2020

First up, LG Display will show new applications for the aerospace market - including 55" transparent and flexible OLEDs used in airplane cabins. LG will also demonstrate a 65" bendable OLED TV, suitable for first-class cabins, that enable users to adjust the curvature of the TV to create a more immersive experience when required. It seems as if interest in OLEDs is increasing in the aerospace industry.

Researchers develop a method to 3D Print transparent OLED displays

Researchers from Korea's Yonsei University has developed a 3D printing technique that can be used to deposit transparent OLED displays on any shape. The new technique 3D prints both the support structure and the 3D screen electronics.

The method is based in Digital Light Processing (DLP) system that prints the transparent plastic frames, and then uses an electrohydrodynamic jet (e-jet) printer to create the OLED layers as seen in the image above.

The Fraunhofer FEP Monarch flexible transparent OLED lighting kit - hands on review

In 2018 the Fraunhofer FEP institute announced it is starting to offer a design kit that includes several flexible and transparent OLED lighting panels. The Monarch Kit includes several colored butterflies samples, and the researchers were kind enough to send us one such kit for a short review.

So first of all, these OLEDs look beautiful. They shine a beautiful uniform colored light and are very nicely done. There's not much functionality, but it shows the potential of flexible OLED lighting quite nicely.
