DSCC: the OLED materials market to grow from $1.7 billion in 2023 to $2.7 billion in 2027

DSCC estimates that the market for OLED evaporation materials (i.e. OLED stack materials) will reach $1.7 billion in 2023, and will grow to $2.7 billion in 2027 (a 11% CAGR from 2023). If UDC will succeed to commercially introduce a blue phosphorescence material, revenues can even be much higher.

OLED materials used in TV applications (and other large-area applications) will grow from $305 million in 2023, to $492 million in 2027, a 13% CAGR. DSCC also sees very fast growth in material used to produce tandem-structure IT displays, which will grow at a 79% CAGR to reach $443 million in 2027.

Researchers from the University of Michigan develop a stable and efficient phosphorescence blue OLED using polariton-enhanced Purcell effects

Researchers from the University of Michigan developed a new OLED emitter system, based on a blue phosphorescence emitter, based on the polariton-enhanced Purcell effect. This new emitter systems offers high stability and high efficiency. 

The basic idea is to start with a light-blue (cyan) phosphorescence emitter (which offers a longer lifetime than a deep blue emitter), and placing it between two mirrors. The distance between the mirrors is controlled so that only deep blue light waves persist and are emitter from the mirror chamber. The researchers also tuned the optical properties of the OLED stack to the adjacent metal electrode which introduced a new quantum mechanical state called a plasmon-exciton-polariton, or PEP. This new state allows the organic material to emit light very fast, thus even further increasing the lifetime by decreasing the opportunity for excited states to collide and destroy the light-emitting material.

Merck in dialogue: Next generation OLED materials

Merck KGaA is a pioneer in high performance OLED material development, supplying a range of materials for AMOLED makers since the industry’s inception.

To learn more about Merck’s materials and views on the OLED industry, we conducted an interview with Dr. Georg Bernatz, Merck Electronics’ Global Head of OLED Technical Marketing. Georg Bernatz has received a PhD in Physics from the Philipps-Universität in Marburg, Germany in 2000. In 2004, Georg joined Merck, where, over the years, he worked in various functions and on various topics in the field of Liquid Crystals for displays. In 2018, Georg changed to OLED, leading OLED Physics Product Research, and in 2020 he became responsible for all Physics & Application Labs in Darmstadt for Display materials. Since October 2023, Georg is heading Merck’s Global Technical Marketing for OLED materials.

Hello Dr. Bernatz. Can you bring us up to date quickly on Merck's current OLED material products? What do you offer to OLED display makers?

Merck KGaA, Darmstadt, Germany is very active in the design, development and production of a broad variety of high performing OLED materials, with a strong focus on hole and electron transport materials (HTM, ETM), host materials for phosphorescent emitters as well as activities in the field of high efficiency blue.

OLED materials developer Credoxys completes its second funding round

Germany-based Credoxys has successfully completed its second funding round, led by deep-tech VC LIFTT and Melchers Group. The company says it will use the funds to commercialize its p-dopant technology in both the Korean and Chinese markets. The company already validated some product candidates with industry partners, and these are ready for customer qualification.

Credoxys is focused on developing novel materials for both the p- and n-sides of OLEDs and organic solar cells (OPVs). The company says its newly developed p-dopants surpass current standards by exhibiting extremely low absorption of visible light and low pixel cross-talk. The materials enable the doping of hole transport materials with deep HOMO levels, making them particularly suitable for phosphorescent blue OLEDs.

Researchers develop a blue fluorescent OLED device with ultra-low turn-on voltage

Researchers from the Tokyo Institute of Technology, Osaka University, University of Toyama and Shizuoka University have developed a fluorescent blue (462 nm) OLED device that features an ulta-low turn-on voltage of 1.47 V (at 100 nits). The researchers say this is very low, as similar commercial blue devices typically need around 4 V.

To achieve that low turn-on voltage, the researchers built a new device, as they realize that the choice of materials significantly influences the device's turn-on voltage. The device itself is an upconversion OLED.

Researchers develop promising near-UV CMAc OLED emitters

Researchers from the University of Manchester, led by Prof. Alexander Romanov, developed a promising new Carbene-Gold-Arylacetylide (CMAc) OLED near UV emitter type. The researchers also detail a strategy to develop longer device lifetimes for such emitters.

The new emitter exhibits an efficiency of 1% EQE, and a lifetime of 20 minutes at a practical brightness of 10 nits (LT50). This is low compared to commercial OLEDs - but it is actually quite outstanding for such an emitter, and the researchers say that this is among the longest lifetimes for a near UV-OLED at a practical brightness ever reported. In addition, organic fluorescent and TADF emitters rarely exceed 1% EQE at practical brightness.

UDC discusses its RGBB display architecture and its advantages in color reproduction and color gamut

During iMID 2023, Universal Display discussed the company's RGBB display architecture, highlighting the advantages regarding color gamut and color reproduction.The RGBB architecture basically adds a fourth OLED subpixel, a light-blue (or cyan) one to a standard RGB deep-color stack.

The current approach to achieve a large color gamut (UDC targets BT.2020) is to use emitters with a narrow spectrum, which enables high color gamut. But there's a catch - each person has a different color perception, and some people are less sensitive to certain colors compared to the "average observer". This causes a display that is based on narrow-spectrum emitters to suffer from distorted perceived colors.

Deep blue OLED emitter developer beeOLED raised $14.4 million

Germany-based beeOLED announced that it has raised $14.4 million in its Series A funding round, co-led eCAPITAL and Innovation Industries. Other investors include KBC Focus Fund and the company's existing investors M Ventures (the corporate venture capital arm of Merck), HTGF, TGFS, and JBN-Invest.

beeOLED was established in 2020 with an aim to develop deep-blue OLED emitters. The company's material technology is based on intra-metallic emission, that has been used in other display technologies in the past but have not been usable in OLED displays yet. beeOLED said that it is the first to make intra-metallic molecules compatible with the vacuum processing technology used in high-volume OLED display manufacturing.

beeOLED's CEO, Dr. Jan Blochwitz-Nimoth has 20+ years experience in managing deep tech teams and companies, and is the founder and CTO of Novaled. Dr. Jan was kind enough to answer a few question we had regarding beeOLED, its technology and business.
