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 2019.

In the early years, several large lighting makers (including GE, Philips, OSRAM, 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.

Konica Minolta built the world's most advanced OLED fab - a Roll-to-Roll flexible OLED lighting fab - that has a capacity to produce a million flexible and color-tunable OLED panels each month. The Japanese company recently announced that it shipped 15,000 flexible OLEDs to a Japanese Tulips Festival - by far the largest OLED installation to date, but real mass production at that fab is yet to be achieved as Konica Minolta still faces technical challenges and constant reorganization.

OLED lighting 2019: out with the old, in with the new

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 2019.

In the early years, several large lighting makers (including GE, Philips, OSRAM, 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.

The DoE grants $1 million to OLEDWorks for flexible OLED lighting R&D

NTHU installs over 200 OLED candle-light lamps at Taiwan's Smangus tribe

Taiwan's National Tsing-Hua University (NTHU) Professor Jou has been researching the hazards of blue light for many years, warning us against the hazards of modern lighting and focusing on OLED lighting as the technology that enables low blue-light emission lighting. In 2015, NTHU started to develop its low blue-light candle-light orange-type OLED technology, initially in collaboration with Wisechip and later with China-based OLED lighting producer First-o-lite.

NTHU has been promoting these candle-light OLEDs for the Smangus tribe in Taiwan's Jianshi Township which has been avoiding artificial light pollution. NTHU and the tribe managed to raise money to produce 240 OLED lamps, 90 for street lights and the rest to light up more than 100 cabins in the tribe's village. This is a beautiful project and hopefully will bring more attention to the hazards of blue light and the advantages of OLED lighting technologies.

Lumtec to expand OLED lighting production in Q4, set to IPO in Taiwan today

Taiwan-based Luminescence Technology (Lumtec) is set to debut today on the Taipei stock exchange emerging stock board. The company says that it plans to expand its OLED lighting production capacity in Q4 2019 from 150,000 50x35 mm panels per month to around 600,000 units.

Lumtec says that it sees a large demand coming from the automotive market for OLED lighting panels, and it expects its utilization rates to reach 100% in the current quarter. This means that the company sees around 450,000 panels shipping in this quarter, which seems highly optimistic, especially as it says that it has currently shipping samples for five companies with volume orders expected in 2020 and the demand from automotive companies is not likely to expand very quickly as first adoption comes from luxury cars.

The DoE grants $1.1 million to Penn State researchers and OLEDWorks to research low refractive index organic materials

The US Department of Energy (DoE) has granted $1.1 million to Penn State University professors Chris Giebink and Michael Hickner for a new project to increase the efficiency of OLED lighting panels.

The researchers, collaborating with OLEDWorks in this project (and previous ones as well), aim to find a way to lower the refractive index of the organic materials which will increase the external efficiency of OLED devices. The basic idea is to insert other molecules and blend them with the existing OLED materials which lower the refractive index without adversely affecting the properties of the original molecules.
