QD-OLED displays

OLED displays are made from organic emitter materials - and are gaining in popularity as these next-generation displays offer excellent image quality and novel form factors.

Quantum Dots are tiny particles that have excellent photonic emission properties - and are used widely today in many LCD displays as the QD photoluminescence features enable the conversion of blue LED light to red and green light to create full-color displays that are better than white-backlit LCDs. QD particles can also be used to create emissive displays, in which the QDs themselves emit the light - read more about QD displays here.

QD-OLED displays are hybrid displays that use a combination of OLED emitters with QD color conversion layers and/or QD emitters. The basic idea is that the display uses only blue OLED emitters, and the QD layers conversts some of the pixels to red and green, thus creating a full color display.

Samsung QD-OLED

Samsung is the only company that have commercialized QD-OLED displays (at least until now). Samsung's QD Displays use blue OLED emitters and quantum-dots that convert the blue light to red and green light. In 2019 Samsung Display announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. A few years later, SDC started to produce panels in its first fab, mass producing TV and monitor QD-OLEDs.

Samsung attracted several customers (Sony and Samsung Electronics for TV panels, and several companies for its monitors), and these displays have been very well received by the market. Samsung is currently producing around a million QD-OLED panels per year. The future roadmap of Samsung's QD-OLED displays is not clear.

In 2019 it was unveiled that China-based display maker TCL is developing a new hybrid display technology that uses a blue OLED emitter coupled with red and green QD emitters. All three emitter materials will be combined and printed using ink-jet printing technology.

TCL callקג this technology H-QLED and said that this could prove to be the technology of choice for TCL's future high-end emissive TV displays. For more information on TCL's H-QLED, click here. The company, however, did not update on its H-QLED technology since 2019.

Will Samsung decide to abandon its QD-OLED technology?

In 2019 Samsung Display announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. A few years later, SDC started to produce panels in its first fab, mass producing TV and monitor QD-OLEDs. The company attracted several customers (Sony and Samsung Electronics for TV panels, and several companies for its monitors), and these displays have been very well received by the market.

Since 2022, Samsung has increased its production yields, and increased its production capacity, and today it produces around 40,000 substrates a month in its 8.5-Gen production line. Reviews of QD-OLED gaming monitors and TVs are very positive, with many analysts seeing QD-OLED as improving over LGD's WOLED panels in terms of image quality. 

But the reality at Samsung Display's QD-OLED division, is likely not so rosy. It seems that the technology is facing both market challenges and technology challenges - which may lead to a decision by Samsung to abandon it altogether.

Samsung Display increases focus on small and medium AMOLED production

A report from Korea suggests that SDC has transferred around 500 of its engineers from its large-area OLED development division, or about 30% of them, to its divisions that focus on small and medium-sized AMOLED development.

According to the report, the main reason for SDC's change of priorities is due to the need to remain competitive with Chinese-based OLED makers that are offering OLED panels at low costs. Samsung estimates that it is ahead of its Chinese competitors by only a year or a year and half, and it is just a matter of time until Chinese companies catch up with South Korea makers (SDC and LGD).

Samsung's upcoming S90D OLED TV lineup will feature displays utilizing both WOLED QD-OLED panels

According to reports from Korea, LG Display requested Samsung Electronics to use its WOLED panels on the same tier as SDC's QD-OLED panels, and Samsung will use both panel technologies in its S90D OLED TV series. Samsung will likely not disclose the actual panel technology to the consumer, and will likely decide on the panel technology per region.

The Samsung S90D will offer 42-, 48-, 55-, 65-, 77- and 83-inch panels. SDC only makes 55, 65, and 77-inch QD-OLED panels, and so in these sizes both QD-OLEDs and WOLEDs will be used. For the 42-, 48- and 83- models Samsung will only use WOLEDs.
