OLED devices use organic semiconductors to create beautiful, flexible and efficient display panels.
Researchers from RUDN University in Russia have synthesized new OLED emitter compounds. These compounds seem to be phosphorescent emitters, based on copper and silver atoms.
The researchers say that the compound platform they created can lead to efficient and cost-effective OLED emitters, and also offer a special molecular geometry that can enable freedom-of-design for developers.
Sharp announced that it has developed, in collaboration with NHK, a 30" rollable 4K OLED panel on an IGZO backplane. This is a direct emission OLED, which sharp says is the world's largest ever produced (LG's OLEDs all use color filters).
Sharp's OLED panel is deposited on a thin-film substrate, and has a thickness of 0.5 mm. The display uses NHK's signal processing and panel driving technologies to "improve the brightness uniformity and video clarity".
In February 2019 Samsung started to produce 15.6" 4K AMOLEDs for laptops - and recently the company also started to produce 13.3" 4K AMOLEDs, already adopted by HP for a new laptop.
Last week SDC hosted an OLED for IT companies, and over 300 employees from laptop producers in Taiwan (including HP, Dell, Lenovo, and Asus) attended the event. During the event, Samsung says that it will add a new OLED panel to its lineup, a 13.3" FHD model - which will be cheaper than the 4K model which will help expand OLED adoption in more laptop models in 2020.
OLED microdisplay maker eMagin reported its financial results for Q3 2019. Revenues were $7.9 million (up from $6.9 million a year ago) and operating loss was $0.4 million (down from $1.3 million in Q3 2018).
eMagin says that these financial results present a significant improvement, with the second highest quarter revenues in the Company's history. The company demonstrated significant improvement in yield and throughput as production volumes increased over 50% from the second quarter.
Xiaomi recently launched new QD-enhanced LCD TVs in China, and its executive Li Xiaoshuang says that the company is planning to launch its first OLED TVs in Q1 2020.
Xiaomi will join several Chinese-based TV makers who already ship OLED TVs, including HiSense and Skyworth. LGD aims to increase its OLED panel shipments to Chinese TV makers from around 300,000 units in 2019 to over 2 million in 2021.
Xiaomi's Mi Watch features a 1.78" 368x448 Super AMOLED display, a Qualcomm Snapdragon Wear 3100 chipset, 1GB of RAM and 8GB of storage. It runs on Xiaomi's own wearable operation system.
The Mi Watch will start shipping in China next week for around $165.
Photonics-based solutions provider Coherent reported its financial results for Q3 2019 - revenues of $335.5 million and a non-GAAP gross profit of $122 million.
Regarding the OLED market, Coherent says that it finally started to receive some new orders for OLED equipment (ELA), following a "stretch" where there were no new system orders. Coherent says that it looks forward to the OLED ramp - with 2020 as a "bit of a recovery over 2019" - but the real strength coming in 2021 and 2022.
