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

Video shows LG Display's latest displays shown at SID DisplayWeek

Jul 21, 2017

A new video shows LG's large SID DisplayWeek 2017 booth. The video begins with some displays we have seen before - LG's latest wallpaper OLED TVs and its Crystal Sound OLED system, but then continues to show some new displays.

LG demonstrated two flexible OLEDs for mobile devices - a 5.5" QHD (1440,2560, 538 PPI) panel and a 5.7" FHD (388 PPI) panel. Both are plastic-based and are conformable (edge-type). The displays offer a brightness of 350 nits. LG says the 5.7" FHD is now in mass production, while the 5.5" QHD will be ready in Q2 2017 (which means it's should already be in production). The video also shows a glimpse of LG's "VR displays" - but no details are given (this was for some reason labeled as confidential).

Pioneer demonstrates new automotive OLED lighting prototypes at CES Asia 2017

Jun 22, 2017

Pioneer demonstrated new automotive OLED prototype applications at CES Asia 2017. First up are these beautiful OLED taillight prortotypes, which use flexible OLEDs that are bent to create these 3D shapes.

Pioneer also demonstrated an updated version of its transparent brake light system, which was first unveiled in January 2016. The idea is that the brake light can be embedded in the back window of the car to create a beautiful design that is safer as it enlarges the back field of view compared to current brake lights.

LGD developed a 77" flexible and transparent OLED display

Jun 22, 2017

LG Display announced that it has developed a 77" flexible and transparent OLED display. The display features a resolution of 4K/UHD (3840 x 2160), a 80 mm radius of curvature and 40% transparency.

LG Display demonstrated two possible applications for this display - above you can see the "smart desk" demonstration, and below you can see a commercial retail demonstration. It is not clear from the press release, but it seems that LGD plans to commercialize such a display in the future.

Yeolight developed new amber OLED lighting and automotive OLED rearlights

Jun 02, 2017

Yeolight Technology (which was spun-off Visionox in May 2015) developed a new bright Amber OLED panel. The panel's size is 85x85 mm (active area 76.5x76.5 mm) and its color temperature is 2000K-2600K. The efficiency is >70 lm/W at 2,000 cd/m2 brightness. The lifetime is over 20,000 hours.

This new panel is still a prototype - but Yeolight says it can already be mass produced at the company's 2.5-Gen production line.

New video shows Wisechip's flexible, transparent and candle-light OLEDs

Mar 30, 2017

Wisechip, the Taiwan-based PMOLED maker, demonstrated its new flexible and transparent PMOLED displays last week in a trade show in Germany. Embedded News TV interviewed the company's R&D manager and published the following video which also shows Wisechip's latest OLED prototypes.

On display at the trade show were two flexible OLEDs - a 1.8" monochrome 160x32 panel, a 1.36" monochrome 128x16 panel. Wisechip also has a 256 x 64 display. Wisechip also demonstrated a new transparent OLED for automotive applications and a round 1.07" 160x136 transparent PMOLED (this one was also on display last year). Wisechip's original plan was to start producing transparent displays towards the end of 2016, but apparently this is a bit delayed. We hear that the displays are nearing production though.

Taiwan-based PMOLED maker Wisechip announced it is developing transparent and flexible PMOLED displays last year, and the company has presented new prototype displays in a trade show in Germany last week.

Wisechip demonstrated three flexible OLEDs - a 1.8" 160x32 panel and a 1.36" 128x16 panel. Both are monochrome (white) panels as you can see in the photo above. The third display is a 256x64 one. The curvature radius of Wisechip's displays is 40 mm. The photo also includes a demonstration of a PMOLED display embedded in a credit card form.

Bentley wants to add transparent OLEDs to future luxury cars

Jan 22, 2017

Luxury British automaker Bentley plans to add new cutting-edge technologies to its future cars - including plug-in hybrid engines and transparent OLEDs. One concept designs apparently shows a transparent OLED on top of wood veneers - so the display is invisible when not in use.

It's great to see another automaker looking into OLED displays - but this won't be easy to achieve in the near future as transparent OLEDs are not in production yet. Both LG Display and Samsung demonstrated transparent OLEDs for the automobile market, though - and of course it makes sense that high-end luxury cars will be the first to adopt these new displays.
