In December 2019 BOE unveiled a 55" 8K (160 PPI) OLED TV prototype produced by inkjet printing. The panel achieves a maximum brightness of 400 nits and a color gamut of 95% DCI-P3.
At SID Displayweek 2020, the company demonstrated this display and gave more details regarding its production process and display structure.
Samsung Display has developed a 18.2" 2560x1440 202 PPI inkjet-printed OLED display, that features the highest current efficiency of any inkjet-printed OLED, with the brightness at 350 cd/m2 (full white).
Samsung Display says that the high brightness was achieved by tuning the top-emission device structure with high performance soluble materials. The high pixel resolution was achieved by modulating the jetting waveform for ejecting ink drops and improving the drop placement accuracy by selecting the right ink formulations in terms of viscosities and surface energies.
Universal Display reported its financial results for Q2 2020. The COVID-19 pandemic continued to impact UDC, as customer orders and shipments declined. UDC reports $58 million in revenues (down from $112 million in Q1 2020 and $118 million in Q2 2020) and a net income of $800,000. Part of the reason for the revenue drop were two orders made in Q1 (worth $44 million) as safety-stock due to the trade concerns and COVID-19 uncertainties.
While the second quarter was very disappointing for UDC, the company reports that demand has picked up in July (the first month of Q3) as customer orders increased. There are still "significant uncertainties" ahead and the company will not provide any guidance until visibility improves.
Kopin Corporation announced in January 2020 that the company developed a new double-stack OLED architecture that enables brighter microdisplays with longer lifetime. Earlier this yeare Kopin announced a new 1.3" 2560x2560 OLED microdisplay, developed with Panasonic and Lakeside Optoelectronic, that uses the new double-stack architecture and achieves brightness of over 1,000 nits.

Kopin now announced that its latest 720p OLED Lightning dual-stack OLED display has exhibited very high brightness of 7000 nits with good color and high contrast. Kyulux explained that to achieve this high brightness, it has worked with its partner, Lakeside Optoelectronics to optimize the duo-stack OLED structure to output color spectrum to match the bandpass of the color filters for high color fidelity, coupled with very high current efficiency and low operating voltage.
Samsung announced several new OLED devices yesterday. We'll start with the new Galaxy Note 20 which sports a 6.7-inch 1080x2400 HDR10+ Super AMOLED Plus display (which could mean this is an RGB display, not a Pentile one). The Galaxy Note 20 Ultra has a larger 6.9-inch 1440x3088 Dynamic AMOLED. The display supports a refresh rate of 120Hz at Full-HD resolution and 60Hz at QHD. According to the Elec in Korea, the Note 20 Ultra display has an LTPO backplane (which Samsung calls HOP).
Next up is the company's 2nd generation Galaxy Z Fold 2 that is an update to the original fold with a larger internal foldable display at 7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED and also a larger 6.23" 816x2260 Super AMOLED cover display. The Fold 2 also improves the hinge design and sports an ultra-thin-glass cover (like the Galaxy Z Flip).
Kyulux presented a new paper at SID Displayweek, that shows the latest progress of the company's Hyperfluorescence OLED emitter platform. You can see the latest performance chart below.
Hyperfluorescence combines TADF and fluorescence emitters, which enables high-efficiency (~100% IQE) emitters that feature long lifetimes and a very narrow emission spectrum. The company's yellow HF emitter is already commercialized, and now Kyulux says that its red and green materials are "close to commercialization". The company is also improving the color point and lifetime of its HF blue emitters.

Notion Systems received a major order of several n.jet display inkjet printing systems from a major Taiwanese display manufacturer and underlines its leading position in the market.
The n.jet display series prints functional layers in various steps of display production, and for various display technologies. This includes rigid, flexible, OLED, QLED, and LCD displays. In addition to its unparalleled precision, the platform complies with the highest demands on process environment and process stability. Specifically developed features, like the no.mura printing technology solve long-standing challenges in the industry and enable an efficient, additive use of the valuable materials involved in manufacturing the next generation displays.
OTI Lumionics announced that its latest ConducTorr Cathode Patterning Material (CPM) materials will start shipping by the end of 2020 to customers, which will use these to create OLED displays with under-the-display camera and face unlock technologies.
OTI says that the first mobile devices using OTI’s CPM materials are expected to ship in 2021. Last month we reported that Visionox will soon start shipping AMOLED displays with an under-the-display camera, it could be the Visionox is OTI's first customer. OTI received a strategic investment from LG recently, which could hint that LG could be OTI's customer as well.
This week at SID DisplayWeek LG Display will launch a new OLED microdisplay. Branded as OLEDoS, LGD's display is a 0.42" 1280x720 (3,500 PPI) panel that uses a color-filter based design.
LGD's microdisplay achieves very high brightness (over 4,000 nits) and the color gamut is quoted as DCI > 97% DCI.

Poland-based TADF developer Noctiluca reports that the company continues to improve its emitter platform, and the company recently concluded testing a new family of emitters that have revealed great TADF properties, good to excellent QY and blue emission. Noctiluca released the raw data (available from company under the NDA) that details the performance of several new blue emitters. Here is a link to the summary of these results.
Noctiluca’s Team have a history of making custom high purity compounds to specific needs, and its TADF compound family has a high level of customization which will allow the company to tailor its materials for specific OLED stacks. In fact the company's next step is to work with industry leaders and OLED material developers to test its materials within commercial-grade OLED stack architectures to continue its development work and enhance the performance of its OLED emitters.
