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.

Latest Transparent OLED news

AUO demonstrated its latest OLED and Micro-LED technologies at SID-2018

Taiwan-based AU Optronics (AUO) demonstrated the company's latest OLED, LCD and Micro-LED technologies at SID 2018.

The company had a relatively small OLED demonstration area, showing its True-Circle in-cell Touch AMOLED displays (1.2" and 1.4") unveiled in May 2017. These displays are already shipping. AUO also unveiled its large 13" transparent AR AMOLED (68% transmittance). This transparent OLED was shown for the first time. The 13" panel features a resolution of 1150x575 (100 PPI) and a brightness of 200 nits.

Visionox demonstrate its first transparent OLED at SID 2018

China PMOLED and AMOLED producer Visionox demonstrated its first transparent OLED at SID Displayweek, a small transparent blue panel (60% transmittance).

The tag next to the display said this was a transparent AMOLED, but it is more likely that it was a PMOLED display - after all it was a simple monochrome blue one. In any case it is great to see Visionox developing transparent displays, in addition to the other next generation technologies it demonstrated at DisplayWeek.

Samsung Display demonstrates its latest OLED displays at SID 2018

Samsung Display had a large booth at SID DisplayWeek, showcasing its latest OLED technologies (and also its QD-enhanced LCD TVs).

A large part of SDC's booth was dedicated to the company's automotive OLED technologies which included a wide range of flexible and rollable OLED displays - including flexible, transparent, rollable and a lightfield display.

LG Display demonstrated its latest OLEDs at SID DisplayWeek 2018

LG Display showcased several of its OLED technologies at SID DisplayWeek. The most impressive display was a 77" panel that is both flexible and transparent. The large panel features a 4K (3840x2160) resolution and 40% transmittance. The bending radius of the display is 80 mm. This seems to be the same display announced in June 2017.

LGD also demonstrated, for the first time, its VR OLED display, developed in collaboration with Google. This is a 4.3" 3840x4800 (1443 PPI) glass-based display on an LTPS backplane, that supports a refresh rate of 120Hz.

AUO developed a transparent 13" OLED for AR applications

Taiwan's AU Optronics (AUO) developed a 13-inch 100 PPI transparent OLED display, specifically for AR applications. This is a highly-transparent display - with 68% transmittance.

AUO 6" transparent OLED prototype (2011)

To achieve such high transparency, AUO optimized the TFT array layer stack, the OLED cathode pattern and the encapsulation. This is the first transparent OLED AUO has developed since 2011. It will discuss this new display at SID Display 2018 - and will hopefully demonstrate it as well.

Volkswagen unveils a new autonomous EV concept with transparent OLED brake lights

Volkswagen unveiled a new concept car, the I.D. Vizzion, which is an autonomous electric car. VW actually aims to release this car by 2022 at the latest, although the released model will have a steering wheel, unlike the concept one which does not.

The concept I.D. Vizzion, at any case, includes transparent OLED lighting strips embedded into the back windshield that are used as brake indicators. This same idea was demonstrated by Pioneer in early 2016.

Will Samsung target new applications now that its smartphone OLED lines are under-utilized?

In the past few weeks we heard many reports that following lower than expected OLED orders from Apple (due to disappointing iPhone X sales) Samsung Display has suddenly found itself with under utilized OLED production lines.

Samsung already said that it aims to find new customers for its OLEDs, mostly in smartphone makers in China. Some analyst say however that this won't be so easy as the higher costs of SDC's AMOLED displays deter some of its potential customers, who prefer to opt for lower-cost high-end 18:9 LCDs.
