OLED (Organic Light Emitting Diodes) are light emitting panels made from organic (carbon based) materials that emit light when electricity is applied. OLED are used today to make beautiful and efficient displays and large, efficient and beautiful lighting panels.
An OLED 'light bulb' is a thin film of material that emits light. OLED is the only technology that can create large "area" lighting panels (as opposed to point or line lighting enabled by LEDs and fluorescent bulbs). OLEDs can be used to make flexible and transparent panels, and can also be color-tunable. OLEDs emit beautiful soft diffused light - in fact OLEDs lighting is the closest light source to natural light (with the exception of the old incandescent lamps).
The OLED lighting market
OLED is an amazing technology for lighting - it creates beautiful, efficient and healthy light sources. OLED lighting has great promise but unfortunately the high price of production is a challenge that no one has managed to overcome and OLED lighting remains a small niche industry as of 2021.
In the early years, several large lighting makers (including GE, Philips, OSRAM, LG, Konica Minolta, Panasonic, NEC and others) had active OLED lighting programs, but slowly almost all of these companies dropped out of the market - for various reasons - but the main one being that the large investments in large scale production are not certified to lead to market adoption and the competition with LED lighting is extremely difficult.
There are several companies that still develop and produce OLED lighting panels, but the production volume is still small and most makers target niche markets such as the automotive, health and premium designer markets. Some makers are also offering OLED lamps - click here for our OLED lamp listings.

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), led by Prof. Peidong Yang, developed a new 3D printing ink based on perovskite materials, that exhibits unity photoluminescence quantum yield (PLQY). Interestingly, as it is a 3D printable ink, it is possible to create luminescent objects from it, as seen in the image below:
The researchers brand the new ink as 'supramolecular ink', and say it is produced without any rare metals. It is a combination of several powders containing hafnium (Hf) and zirconium (Zr), and is made at room temperatures. In a process called supramolecular assembly, tiny molecular building block structures are self-assembled within the ink. These supramolecular structures enable the material to achieve stable and high-purity synthesis at low temperatures.
US-based OLED lighting developer OLEDWorks seems to be focusing on automotive OLED lighting solutions for the last few years, and the company now announced a separate brand for automotive OLED lighting - Atala.
OLEDWorks explains that the new brand will support a line of automotive qualified OLED lighting products designed specifically for Tier 1 suppliers and original equipment manufacturers (OEMs). The name Atala originates from an acronym for advanced technology for automotive lighting applications.
US-based Pixelligent is an advanced materials company that delivers next generation optical materials applications in lighting and displays. For the OLED industry, Pixelligent offers materials that significantly increase light output by increasing the refractive index of materials in the device.
Pixelligent's President and CEO, Craig Bandes, was kind enough to answe a few questions we had, to learn more about Pixelligent and its solutions for the OLED industry.
Hello Craig! Can you explain your technology and materials and how they enhance the efficiency of OLED display?
We are best known for our high refractive index (HRI) nanocrystal formulations and dispersions that deliver breakthrough performance in next-generation electronics, like extended reality, displays, optics, and sensors. We designed our PixJet®, PixNIL®, and PixClear® products to offer the best combination of brightness, clarity, operating efficiencies, and device-lifetime.
Germany-based OLED lighting developer Inuru announced that it has raised $10 million, from Aper Ventures, Adamed Technology (the venture capital arm of Polish pharmaceutical company Adamed Pharma), ARIA, and a group of business angels. Inuru says that the new funds will enable it expand into new industries with its interactive OLED labels.
Inuru says it is now focusing on two sections: medication and entertainment. Inuru's main focus for the medication industry is to use its OLED labels to assist patients in learning the expiration date on medication and to adhere to the prescribed guidelines. The company says that the repercussions of non-adherence and medication mismanagement contribute to an estimated $600 billion in preventable healthcare expenses and 325,000 annual fatalities.
China-based Yeolight demonstrated new OLED lighting taillights designs at the Automotive Lighting Exhibition in Shanghai. In the video below you can see some of the various prototypes:
And in the photos below you can see some others. These are interesting prototypes. Some of these have been developed in collaboration with automotive makers, for example Geely-owned Zeekr.
Many years ago, The W Hotel in Taipei installed an OLED installation called You Fade to Light, designed by rAndom International creative studio and powered by Philips' OLED lighting panels. This beautiful piece consists of 2,000 modules, each lighting up as a response to people moving in front of it.
After several years these OLED panels started to fail (and fade, which is rather ironic given the installation's name), and now the hotel replaced the OLED panels with microLED-powered panels. It is said that the microLEDs achieved the same level of uniformity and light output of the OLEDs, maybe even surpassing them.

Researchers from the Korean Advanced Institute of Science and Technology (KAIST) and the Asan Medical Center (AMC) have developed the world's first OLED-based catheter for phototherapy within internal organs.
OLED-based light therapy has been researched, and even commercialized, before, but only for external use. This is the first time that such a device has been developed for internal use. The device developed by the joint research team is a catheter-shaped OLED platform that can be directly inserted into tubular organs like the duodenum and is water-resistant.
Audi has unveiled the 2024 Q8 (and SQ8) SUV, which will sport OLED taillights, similar to the ones used in the 2022 Audi A8. These digital taillight OLEDs are supplied by OLEDWorks.
Audi recently announced that the 2024 Audi Q6 e-tron will come with its its second-gen OLED taillight technology, with 360 individual OLED panels built into 6 different lighting panels. The Q8 will likely use Audi's first-gen design, as it is said to be similar the the 2022 A8. The Q6 e-tron will also sport an AMOLED display in the dashboard.
