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.

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.

Pioneer withdraws from the OLED lighting market, KMPO dissolves back into Konica Minolta

In March 2017 Konica Minolta and Pioneer announced that the two companies are set to merge their OLED business unit, and on June 2017 the new 50:50 joint venture, called Konica Minolta Pioneer OLED, was officially established.

Pioneer was recently acquired by Hong Kong private equity firm Bearing Private Equity for $904 million, and the company is now trying to focus its business, and we learned that it has decided to quite the OLED lighting market. KMPO has been closed and all assets and employees were moved to Konica Minolta. This is quite sad news regarding Pioneer who's been active with OLED lighting for many years (see below).

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.

ETNews: LG Display to focus on automotive OLED lighting and not quit the OLED lighting market completely

A couple of weeks ago we reported that LG Display has decided to quit the OLED lighting market, as it found it difficult to ramp out production and lower its production costs. It was not clear what's the future of LGD's automotive OLED lighting business, but now we have an update from Korea.

According to ETNews, LG display has indeed found it difficult to win orders for its consumer OLED lighting products, and has decided to "reduce" its Luflex OLED lighting product line. LGD, however, is not quitting the OLED lighting market - but is stepping up its efforts to supply automotive OLED lighting solutions.

Is LG Display pulling out of the OLED lighting market?

Update: ETNews reports that LGD will not quit the lighting market completely, but change its focus to automotive OLED lighting

According to our information (from several sources within the industry), LG Display has decided to quit the OLED lighting market. LG found it difficult to ramp out production in its new OLED lighting fab and from what we understand the future prospects of the business did not seem good enough for the company.
