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:
Rtings.com burn-in tests show Samsung's QD-OLEDs suffer from worse burn-in compared to LG's WOLEDs
Review web site Rtings.com has performed an extensive accelerated longevity test for over three months, testing the latest QD-OLED and WOLED TVs.y
Rtings reports that both QD-OLED displays (Samsung S95B OLED and the Sony A95K) showed signs of image retention, and it seems in general that the QD-OLED displays suffer from worse problems compared to LG's WOLED. Some of Sony's WOLED TVs also showed signs of image retention.
Samsung to start shipping its 77" S95C QD-OLED TV next month, for $4,500
Last month Samsung announced its S95C QD-OLED TV, and now the company starts accepting orders for its 77" model - for $4,500. The TVs will ship on March 6.
The S95C offers a 4K resolution, 144Hz refresh rate, Tizen 7 OS, Dolby Atmos, Gaming Hub and an external connector box (One Connect). The peak brightness is "over" 2,000 nits. It will be available in 55", 65" and 77".
Samsungs reports its Q4 2022 financial results, OLED sales declined as demand for smartphones fell
Samsung Electronics reported its financial results for Q4 2022, with revenues of $57.3 billion, and an operating profit of $3.5 billion.
Samsung says that the "business environment deteriorated significantly in the fourth quarter due to weak demand amid a global economic slowdown". SDC's mobile AMOLED panel business earning declined, as demand for smartphones fell, but its large-area panel business seen a smaller loss as it is increasing sales of QD-OLED panels.
UBI: Samsung to increase its QD-OLED capacity by 50% by 2024
UBI Research says that Samsung Display has decided to increase its QD-OLED production capacity, from 30,000 monthly substrate to 45,000 - that's a 50% increase - by 2024.
UBI also says that Samsung has updated its QD-OLED material stack (now called QM2), with an upgraded ETL green layer, and has started to recycle the waste materials in its production process.
Omdia: Samsung to increase QD-OLED TV panel shipments in 2023, LGD to lose OLED TV market share
Omdia posted an interesting market analysis, saying that Samsung Display is looking to increase its OLED TV market share, and will push QD-OLED TV shipments strong in 2023. SDC will increase shipments by 141% in 2023, and will continue to increase production.
Samsung's production increase will be met by an increased number of suppliers - not just Samsung and Sony as in 2022, but other companies will start offering QD-OLED TVs (Philips, TCL and Sharp).
TCL plans to sell its first QD-OLED TV in 2023
Update: TCL says it issued that statement by mistake, and it has no current plans to ship a QD-OLED TV in 2023
TCL announced that it is set to launch its first QD-OLED TV in the coming months. If all goes according to plan, TCL will be the third company (following Samsung and Sony) to offer QD-OLED TVs.
That's the only information we have so far. The TV will likely be offered in 55-inch, 65-inch and/or 77-inch sizes (the available QD-OLED panels today) with a 4K resolution and a refresh rate of 144Hz. That's the current QD-OLED standard.
Samsung to start producing 49-inch and 77-inch QD-OLED panels
Samsung announced that it is set to start producing several new QD-OLED panels and products in 2023. In addition to the current 34-inch, 55-inch and 65-inch panels, it will also offer a 49-inch 240Hz ultra-wide 5120x1440 QD-OLED for gaming monitors, and a 77-inch TV panel.
Samsung will adopt the new 49-inch ultra-wide QD-OLED panel in its upcoming Odyssey OLED G9 monitor. We already knew Samsung has finished developing this panel back in November when MSI unveiled their own QD-OLED monitor project. The 77-inch panel was also unveiled before.
UBI Research: the OLED materials market will grow 8.6% annually to reach $2.75 billion by 2027
UBI Research says that according to its latest study, the OLED emitter market is set to grow from around $1.82 billion in 2022 to $2.75 billion in 2027, with an annual growth rate (CAGR) of 8.6%.
In 2027, UBI expects Samsung's emitter material orders to amount to $680 million - fueled by growth in foldable OLED panels. BOE's emitter material orders will reach $380 million, and LG Display's - $230 million.
MSI shows a 240Hz QD-OLED Monitor slated for early 2023
MSI unveiled an upcoming monitor, a QD-OLED super ultra-wide curved display, that will offer a 240Hz herz. MSI did not disclose anything else - beyond saying that the current name is Project 491C.
This is the first time we publicly hear of a 240Hz QD-OLED display. Samsung currently produces a single monitor QD-OLED panel, a 34-inch curved 175Hz 3440x1440 display.
Kateeva starts to ship 8K QD deposition systems to Samsung Display
According to reports, Kateeva started to ship quantum dots inkjet printing equipment to Samsung Display, for the production of QD-OLED panels. It appears as if Samsung is interested in producing 8K QD-OLEDs, and its current inkjet printing supplier, Semes, is not ready with printers that support 8K QD deposition.
Kateeva announced that it has designed a new system, called the YIELDjet Jarvis, that supports 8.5-Gen substrates and can indeed enable 8K TV deposition. Kateeva says that the Jarvis system has the ability to print using solvent-based RGB inks or nanoparticle inks with its proprietary ink recirculation system to ensure uniform particle distribution.
