In this article, we interview two of TCL CSOT's executives: Ming-Jong Jou, Chief of the Technology Planning Center at TCL CSOT, and Dr. Weiran Cao, General Manager of IJP OLED Center of TCL CSOT. Dr. Cao and Jou both discuss TCL CSOT's OLED technology, current status, future plans, microLED displays - and the company multiple display technology strategy.

Hello Dr. Cao, thank you for this interview. Let's start with AMOLED displays. TCL CSOT is introducing new technologies, such as Partitioned Frequency Division, High PPI, Real RGB Stripe. I wonder how TCL CSOT sees the future of AMOLED technology? Will the main technology drive continue to be towards increased efficiency, or will performance metrics such as resolution or color gamut be important too?

TCL CSOT is advancing two types of OLED technologies: traditional FMM OLED and Inkjet-printed OLED (IJP OLED), and TCL CSOT is widely recognized as the global leader of IJP OLED technology.

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.

Notion Systems, a leader in ink jet printing for industrial applications, has been active in the display market for a long time. The company is now promoting its EHD technology for high precision printing. Here’s an interview we conducted with Antonio Schmidt – SVP Sales & Business Development and Jochen Seeser – Senior Process Development Manager, Notion Systems.

Hello Antonio and Jochen, thank you for your time. In 2022, you started offering EHD printing systems. Can you explain how this technology works and what applications does it enable in the display industry?

Notion Systems has been active in the display market since 2016, when we delivered an n.jet display for pixel printing to a lab of a leading display manufacturer in China. Since then, we have supplied several inkjet displays for RGB printing and encapsulation to various R&D and production sites in China and Taiwan. I think we can also claim that we are the only manufacturer, along with perhaps one other U.S. competitor, that has multiple systems in operation for 24x7 display production.

This is a sponsored post by Amorphyx, where display industry consultant Ian Hendy has interviewed Amorphyx's CEO John Brewer

Q: Can you start by telling us a little about what Amorphyx does, John?

Amorphyx has several fundamentally new technology platforms that provide for TFT performance improvements in three areas: (1) Switching speeds, with options to move to the Tera-Hz range ultimately, (2) Power, where the IGZO AMeTFT can achieve even lower power performance than today’s LTPO OLED Pro Motion displays and better refresh range, and (3) Small transistor size.

Our technology platforms are lower cost than the alternatives, and move from amorphous and crystalline semiconductor approaches, to devices based on different effects that do not have a semiconductor at all, yet can still drive a display, drive current, deliver grey scale and switch very fast. Or they can operate a flex IC at higher clock speeds than known today.

For now, our main commercial focus is on IGZO AMeTFT which is fundamentally a potential replacement transistor for LTPS or LTPO used in modern OLED phones and has the capability to replace more highly compensated LTPO circuits in modern Smartphone displays due to enhanced stability.

Poland is aiming to become a major innovation and high-tech hub, and the country is already enjoying a growing industry, focusing on IT, bio-technology, robotics and nanotechnology.

Poland has a strong material science and development expertise, and in recent years we have been seeing OLED and display-related ventures out of Poland. It seems Poland is poised to become an interesting location to watch for future innovation in the OLED industry.

In 2020, Ergis launched its first product for the optoelectronic applications (such as the display market and photovoltaics) - the Ergis noDiffusion films for flexible OLED panels (both displays and lighting) and OPVs. Ergis is using a unique ALD-based technology that enables it to offer high performance films on low cost PET films.

The Looking Glass Factory develops interfaces for holographic, light field displays. Light field displays seem to be advancing, and we invited LGF's CEO and co-founder, Shawn Frayne, to help us understand the technology and to tell us more about the company, its technologies and latest status.

Q: Hello Shawn. Can you give us a short background on LGF, and on your own interest in light field displays?

Ever since I saw the holographic shark swallow up Marty McFly in Back to the Future II, I have been pursuing the dream of the hologram a way to create and share images and memories that are as lifelike as people and things in the real world. However, despite living in a 3D universe, our digital interactions, memories and creations remain trapped on flat, 2D screens. I wanted to change that, and that’s how and why Looking Glass Factory started.
