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).

OLED lighting on the market

Several companies already offer OLED lighting panels - including Philips/OLEDWorks, Osram, LG, Konica Minolta and others. Current production lines are still small, and prices are still high, but we see rapid advances in performance and price and hopefully OLED lighting prices will drop dramatically once mass production is achieved.


Above you can see a video review we posted a couple of years ago, showing sample OLED panels from Philips, OSRAM, Blackbody and Lumiotec. Current panels on the market are larger, brighter and more efficient than those available back then, and some companies already produce flexible and transparent panels as well.

The OLED lighting market

There are several companies that produce OLED panels, but most of these panels should be considered as "samples" as production volume is low. The leading OLED producers at this stage are LG Display, OLEDWorks/Philips and Konica Minolta. LG is offering the widest range of panels, including flexible panels and the largest OLED in production (at 320 x320 mm).



Philips/OLEDWorks is focused on functional light - bright, efficient and homogenous panels. The company's main panel is the FL300 Brite Lumiblade, which is a 100x100 mm panel that offers a 300 lumens, 50 lm/W, 10,000 hours lifetime (LT70) and is only 1.4 mm thick.

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

OLED lighting future

It is still not clear when and if OLED lighting will break out and become a real market. Most market analysts agree that OLED lighting will eventually become a large market - but it will take time.

IDTechEx OLED lighting cost and market (2016-2025)IDTechEx OLED lighting forecasts (April 2016)

IDTechEx estimates that the OLED lighting market will reach more than $1.8 billion in 2025 at the panel level. IDTechEx is optimistic about OLED lighting in the long term - because "OLED lighting exhibits key characteristics of a disruptive technology". Yole Developpement predict a $1.5 billion OLED lighting market in 2021 (up from nearly $30 million in 2015).

OLED-Info readers get a 20% discount on Fluxim's large-area OLED simulation software

May 22, 2017

Leading simulation and measurement tool provider Fluxim and OLED-Info have teamed up to offer a 20% discount on Fluxim's large-area OLED simulation software LAOSS.

Fluxim Laoss software for AMOLED displays and OLED lighting image

LAOSS is a software tool that simulates large area semiconductor devices (OLED and PV), taking into account the voltage drop in the electrodes due to important resistive effects when the size of the device increases. LAOSS facilitates electrode layout optimization and material choice, which can save substantial time and resources. Both OLED lighting panel design and study of AMOLED pixel cross-talk is just a click away.

Researchers develop an innovative efficient lighting source based on laser-excitated graphene

May 19, 2017

Researchers from the Institute of low temperature and structure research in Wroclaw, Poland, developed a new white light source based on graphene-foam. Graphene does not have a band-gap, but this device uses a continuous-wave laser to excitate the graphene and opens up a bandgap which results in light emission that UV to near-infralight.

The researchers say that the light spectrum of this device is similar to the spectrum of the sun which is better than current light sources such as LEDs that offer light spectrum with strong peaks (the main problem is the strong blue light emission in LED lighting). This design can achieve a high efficiency (over 200 lm/W), high color rendering index (CRI > 99) and a broadband warm white color. The lifetime depends on the laser, which can be over 10,000 hours.

OLEDWorks introduces its latest OLED panel, the Brite Amber

May 10, 2017

OLEDWorks introduced a new OLED lighting panel, the Brite Amber. This panel is free from any blue emission and OLEDWorks sees applications in the healthcare, senior living and residential markets. This upgrade to OLEDWorks' existing Amber panel features a higher brightness of 2,000 cd/m2.

The Brite AMber features an efficiency of over 50 lm/W and the lifetime is over 25,000 (but OLEDWOrks does not mention at what brightness level). The panel is 41.5 x 101.6 mm in size (active area 88 x 25 mm).

OLEDWorks aims to release 80-100 lm/W flexible OLEDs by 2018

Apr 24, 2017

OLEDWorks latest panel is the Brite 2 - announced in March 2016. The Brite 2 offers a brightness of 300 lumens, a high CRI (>90) and an efficiency of 60 lm/W. According to the company's roadmap, OLEDWorks aims to release 80-100 lm/W flexible panels by next year.

OLEDWorks technical roadmap 2016-2020

By 2020, OLEDWorks' panels will have an efficiency of over 100 lm/W and a lifetime of over 50,000 hours (LT70).

Audi's latest Sportback Concept car sports OLED lighting taillights

In 2015 Audi demonstrated a luxury electric crossover concept car, the e-tron quattro, which sported OLED displays and OLED lighting in its frontlights and taillights. Audi is soon set to unveil its latest e-Tron concept, this time of a sportback edition, which also uses OLED tail lights.

Audi did not show the new car yet, but did release the video you see above demonstrating the OLED taillights, and also the image below.

LG's Wall of the Sun is the world's largest OLED lighting installation ever with 30,000 panels

Apr 07, 2017

LG Display has put on an ambitious OLED lighting display at Euroluce which is a part of the Milan Design Week. LG actually has two booths, with the first one designed by Tokujin Yoshioka. Tokujin's installation is called Wall of the Sun, and it uses 30,000 of LGD's OLED lighting panels installed on the wall.

This makes this installation the world's largest ever OLED lighting installation, which is double in size compared to Konica Minolta's OLED Tulip installation from 2015. This seems to be a very impressive display. The 15 chairs scattered on the floor, by the way, are embedded with LGD's OLED TV panels.

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.

The Holst Centre: flexible OLED lighting is an excellent solution to illuminate touch controls

Mar 27, 2017

The Holst Center presented a new functional demonstrator that uses the Holst' in-mold electronics (IME) technology to show new human-machine interfaces in automotive electronics and consumer appliances. One of the new technologies embedded in this demonstrator is flexible OLED lighting that is used to illuminate touch controls.
