Researchers improve the lifetime of OLED devices 4X by adopting a deuterated host material

Researchers from Tsinghua University in Shenzhen, China, have managed to dramatically increase the stability of OLED devices by the adoption of deuterated host material.

The researchers, led by Prof. Man-Chung Tang, have designed and synthesized deuterated anthracene-based hydrocarbon PNA as the new host material. The researchers have observed that the faraday loss decreases with the increase of the deuteration degree.

Next-generation OLED technologies that will enable brighter and more efficient displays

OLED displays have been gaining popularity rapidly, and are already the dominant smartphone display technology. OLEDs are also the display technology of choice in the smartwatch market, making inroads into the TV, monitor, laptop and tablet markets. The future of the OLED industry looks bright.

In recent years, the focus of the industry, beyond increasing capacity and reducing production costs, has been improving the performance of OLEDs in the areas of display brightness, efficiency, and lifetime. Brightness is required in many applications - from TVs (for HDR and to view in ambient lighting) through smartphones (outdoor viewing) to automotive, and efficiency is a plus in any scenario (but mostly in mobile displays). Display lifetime is already good enough for many applications, but in some cases (like automotive, and IT displays) it is critical. These three properties usually go together - if you can make more efficient OLED displays, you can drive them at a lower current to achieve the same brightness, and so lifetime increases, or you can achieve higher brightness, etc.

Deuterium's Impact on OLED Displays

This is a sponsored post by Clearsynth

In the ever-evolving field of display technology, OLED displays have emerged as a prominent player due to their ability to deliver stunning visuals, energy efficiency, and flexibility.

One key component that has contributed to the success of OLED displays is deuterium, a stable isotope of hydrogen. Deuterium's impact on OLED displays can be seen in its potential to magnify these devices' overall performance and lifespan.

  • Deuterium (2H, D): Discovered in 1931 by H. Urey, who won the Nobel Prize in 1934 and named it Deuterium.
  • Stable, nonradioactive isotope of hydrogen with one proton and one neutron in its nucleus
  • Natural abundance of 0.015% of hydrogen atoms on Earth

Deuterium, a heavier isotope than hydrogen, offers several advantages in OLED displays. First and foremost, deuterium is known to increase the brightness and efficiency of OLED displays. TV Panel manufacturers use OLED materials to generate the 3 primary colours (red, green, blue) in full-colour display. They had a challenge of large electronic power consumption for blue OLED relative to green and red OLEDs. This has been successfully overcome by deuterated blue OLED emitters which provide higher stability and prolonged lifetime, resulting in greater brightness and efficiency.

LG Display aims to expand the use of deuterated OLED compounds

In 2021, LG Display started to adopt deuterated OLED compounds in its WOLED panels, to improve the lifetime, efficiency and brightness. Today, all of LG's WOLED TV panels use deuterated blue OLED emitters, in which hydrogen is replaced by its more stable isotope, deuterium. The higher stability enables longer lifetime, which in turn enables higher brightness and efficiency.

It is now reported in Korea that LG Display now aims to expand the adoption of deuterated OLED compounds to its red and green and yellow emitters, and also other layers in the OLED stack. If this report is true, it means that LGD will also use the technology in its mobile (p-OLED) panels, not just its OLED TV ones.

LG Chem sells its display polarizer business for $800 million

In 2020, LG Chem announced that it has sold most of its LCD polarizer business to China’s Ningbo Shanshan, in a $1.1 billion deal. LG Chem retained its automotive LCD polarizer and its OLED polarizer businesses. The company now announced that it sold all of its remaining display polarizer business to two companies, for around $800 million deal - the polarizer materials business to Hefei Xinmei Materials Technology ($616 million) and the polarizer production business to Shanjin Optoelectronics ($200 million).

Researchers combine classical computing with quantum computing to discover promising OLED emitters

Researchers from Japan's Keio University, in collaboration with Mitsubishi Chemical Corporation, developed a new method to accelerate the design of OLED materials, using a combination of classical computing with quantum computing.

The new approach combines a 'classic' machine learning model with a quantum-classical computational molecular design. Demonstrating the new approach, the researchers discovered a highly efficient OLED emitter, a deuterated derivative of Alq3. The new emitter is not only highly efficient, it is also easy to synthesize.

DSCC: the AMOLED material market to resume growth in 2023, to reach $2.18 billion in 2027

DSCC expects the AMOLED stack material market to grow 4% in 2023, to $1.4 billion, and to reach $2.18 billion in 2027, that's a 12% CAGR from 2023 to 2027. In 2022, the market declined by 10%. The forecast does not include any UDC revenues from blue PHOLED materials, which means that if UDC succeeds in commercializing its blue material, revenues could be higher by hundreds of millions of dollars.

DSCC says that demand for OLED TVs will continue to decline in 2023. In 2022, revenues of OLED TV revenues declined by 17%, and in 2023 revenues will decline 3% further. Growth will resume, though, in 2024, and in 2023-2027 the market will grow at a CAGR of 13%.

What can deuterium do for OLED displays?

The following is a sponsored post by Cambridge Isotope Laboratories

OLED has become the display technology of choice for many commercial products such as smartphones, laptops, tablets, TVs, automotive dashboards and wearables. OLED has advantages with improved image quality (better contrast, higher brightness, fuller viewing angle, wider color range, and faster refresh rates), lower power consumption, and simpler designs (ultra-thin, flexible, foldable, and transparent displays).

OLED, however, faces several technical challenges. While OLED TVs yield better picture quality than common LCDs, they are usually less bright. Research using a compound that has at least one hydrogen replaced with its heavier isotope, deuterium, is showing promise toward achieving greater brightness. Since the bonds between carbon and deuterium are stronger than those between carbon and hydrogen, materials made with deuterated compounds tend to have a longer lifetime, which allows OLED displays to run brighter but still last as long.
