QD-OLED displays - Page 8

DSCC says that inkjet printing technologies for OLED display production is finally starting to gain traction, and the company sees IJP OLED display capacity to increase in a 137% CAGR from 2020 to 2025, to reach 7.1 million sqm.

As you can see from the chart, most of the growth will come from the printing of the quantum-dots color conversion layers in Samsung's QD-OLED fabs. Actual RGB inkjet printing will be confined to JOLED's fab which will start mass producing in 2021. In 2024, China Star (CSoT) will begin printing OLED TV panels at its T8 line.

Samsung Electronics reported its financial results for Q1 2021. The company's revenues was 65.4 trillion Won (around $58.7 billion USD). Operating profit increased 4% from the past quarter to $8.4 billion, as Samsung enjoyed strong sales of phones and consumer electronics, which offset slower sales of displays and semiconductors.

The past quarter saw a fall in the revenues of Samsung's display business, due to weak seasonality of mobile products and a shortage of chips.Compared to Q1 2020, however, earnings improved due to increased adoption of OLED displays in smartphones.

In 2019 Samsung Display formally announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. It was reported before that SDC is started to produce panel prototypes, and is on track to start mass production in Q3 2021.

According to a new report from Korea, SDC is set to begin producing full module prototypes in June this year. In addition SDC had to increase the brightness of its panels as TV makers said it is not enough for premium TV adoption. SDC will produce both TV and monitor prototypes, which it will send to potential customers (such as Samsung Electronics, Sony, and Chinese TV makers). When customers approve the prototypes, SDC will be ready for commercial production.

We are happy to announce a new Metalgrass knowledge hub, QuantumDots-Info.com. Our new site focuses on QuantumDots technologies for the display industry. QDs are already used in many displays, and it is likely that the future will bring us more types of QD Displays, including QDEL and QD-OLEDs.

QuantumDots-Info brings you daily news, commentary, resources and updates about QDs in the display industry. You can subscribe to our weekly QD display newsletter here - and if you have not done so already, be sure to also subscribe to the free monthly OLED newsletter!

In 2019, Doosan Corp spun-off its OLED materials unit, which is now called Doosan Solus (and is listed on the Korean stock market). The company's main OLED products are host materials and EIL and ETL layers.

According to The Elec in Korea, Doosan Solus currently produces so called "advanced" Electron Transporting Layer (aETL) for SDC's mobile AMOLED stack, and the company is now developing specialized aETL to be adopted by Samsung in its QD-OLED stack. Solus has been the exclusive supplier of ETL mateirals for SDC for the past eight years, and its materials are adopted in Samsung's latest M11 AMOLED stack.

In 2019 Samsung Display formally announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. The company is already starting to produce prototypes, and is on track to start mass production in Q3 2021. Reports in 2020 suggested that Samsung Electronics was hesitant about the adoption of QD-OLED panels.

This may have changed now, as we hear that Samsung Electronics has decided to cooperate with SDC and release its first QD-OLED TV next year (2022).

DSCC posted an interesting post with its latest views and forecasts on the OLED material market. The company expects AMOLED stack material sales to grow at a 18% CAGR in the next five years, from $294 million in 2019 to $2.46 billion in 2024. Compared to its previous estimate, DSCC sees higher sales as demand for OLED TVs and OLEDs in the IT market (tablets and notebooks) is increasing.

DSCC also posted an analysis of LGD's new evo OLED material stack. Compared to LGD's "standard" WOLED stack, the evo adds an emitting green layer to improve the brightness by 20%. This of course adds an extra material cost to the panel price.

Korea's The Elec says that Samsung Display aims to start trial runs at its QD-OLED 8.5-Gen production line next month (December 2020).

SDC will brand these displays as QD Displays. The first generation ones will adopt SDC's current hybrid QD-OLED architecture, but later ones may adopt QNED (quantum-rods) emitters. In any case, SDC's plan is to start mass production by the end of 2021, in the first line (15,000 monthly substrates). SDC is also planning a second line to follow the first, to arrive at a total of 30,000 monthly 8.5-Gen substrates.

According to UBI Research from Korea, Samsung Display has managed to improve its quantum dots nanorod LED (QNED) technology, and the company aims to start buying production equipment next year.

Apparently SDC's plan is to replace the fluorescent blue emitters in its QD-OLED TV production process, which will of course turn these TV panels into QD-QNED ones.
