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 - hybrid OLED and QD displays

QD-OLED displays are hybrid displays that use a combinattion of OLED emitters with QD color conversion layers and/or QD emitters.

Samsung QD-OLED

Samsung's QD Displays use blue OLED emitters and quantum-dots that convert the blue light to red and green light. Samsung's so-called QD-OLED displays have been in development for many years. Samsung Display aims to start QD-OLED panel production towards the end of 2021, and Samsung Electronics will reportedly launch the first QD-OLED products in early 2022.

In its first-gen QD-OLED display, Samsung is using a fluorescent blue emitter (will hopefully change to a higher efficiency one in later generations) and ink-jet printed QDs.

TCL H-QLED

In March 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 calls this technology H-QLED and 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 latest QD OLED news:

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.

Samsung: we sold 1 million OLED TVs in 2023 and had a market share of 22.7% in the OLED TV market

Samsung announced that in 2023 it retained its market-leading position in the TV mraket, with a 30.1% market share (revenues). The company also disclosed that it sold 1.01 million OLED TVs in 2023 - mostly QD-OLED TVs, and some WOLED TVs as well.

Samsung quotes Omdia saying that it had a 22.7% market share in the OLED TV Market (by revenue), which is pretty impressive, as the company is relatively very new to this market.

Samsung unveils its 2024 OLED TV lineup

Samsung Electronics announced its 2024 OLED TV lineup, with 3 series. The company's flagship OLED TV for 2024, the S95D, offers 55-, 65-, or 77-inch 4K 144hz QD-OLED panels, offering high brightness (up to 3000 nits peak brightness), a new anti-glare coating to minimize reflections, Tizen 8.0 OS, and an external One Connect box for a sleek design. The S95D offers AI-Enhanced color accuracy - validated by Pantone.

SDC upgrades its QD-OLED line, starts producing 31.5" 4K panels

Samsung Display announced that it is beginning to produce a new 31.5" 4K QD-OLED. This is SDC's highest density QD-OLED display, at 140 PPI. The company recently upgraded its QD inkjet printing deposition system to support this higher resolution. It will also enable SDC to produce 8K 65" QD-OLED displays (that will also be 140 PPI). 

Samsung Display also announced that next year it will start producing 27" QHD QD-OLED monitor panels that will support a 360Hz refresh rate, targeting the gaming monitor market.

Rtings.com posts the results of its 10-month OLED and LCD display longevity tests

RTINGS.com posted an interesting article, detailing the results of their long-term (10-months) longevity tests on several OLED and LCD TVs and monitors. The test is simple - display a CNN feed constantly, and checking what happens. Note that CNN changed their logo a bit a few months into the test, but the team did not make any changes to the test itself.

As is expected, OLED monitors and TVs suffer from image retention problems, and the CNN logo is visible in some of these panels, when showing a gray screen. Some TVs suffer more than others.

UBI: Samsung to order only a limited number of WOLED TV panels from LGD in 2024

In July 2023, Samsung officially launched the 83" 83S90C, the company's first TV to use LG's WOLED panels, following several years of negotiations and hesitation by the Korean rivals.

It was assumed that Samsung's total orders from LGD will be limited (as the 83-inch are expensive and not highly popular), and according to UBI, the total number of panels that LGD actually shipped to Samsung is only 'several thousands'.
