OLED-Info is the world's leading OLED display industry portal since 2004. We provide a multitude of services to the OLED market based on our extensive knowledge hub and industry connections.
OLED devices use organic semiconductors to create beautiful, flexible and efficient display panels.
According to reports from Korea, Unijet has supplied China-based Sidtek with inkjet printing systems, used for thin-film encapsulation (TFE) deposition of OLED microdisplays. This is Unijet's first sell of a commercial TFE printing system.
Sidtek, established in 2016, is now producing 0.39" XGA OLED microdisplays, which are available on the OLED marketplace. Sidtek's 0.39" display is available in a color version (1,000 nits) or a monochrome one.
DSCC says that Q3 2021 was a record quarter for foldable smartphones - with shipments growing 215% from Q2 2021 and 480% from Q3 2020 to reach 2.6 million units. Samsung Electronics controls the market with a 93% share, followed by Huawei (6%).
DSCC expects the growth to continue and shipments in Q4 will reach almost 4 million units. Looking at specific models, the Galaxy Z Flip 3 has a 60% share, followed by the Galaxy Z Fold 3 with a 23% share.
OLED makers are using gold crystals to monitor and control the deposition of organic materials. Many OLED producers choose INFICON's crystals for this demanding task.
INFICON recently launched a new high-precision sensor crystal line that features improved activity stability, which leads to less activity dips and improved deposition rate stability.
The Fraunhofer FEP, in collaboration with GlobalFoundries Dresden Module One and digades, developed an ultra-low power color OLED microdisplay. The researchers at the Fraunhofer say that this display consumes the least power compared to all available microdisplays.
The new microdisplay was developed as part of the Backplane project, funded by the German government (SWMA grant number100392259). The researchers presented a prototype display that features two primary colors and a QVGA (320x240) resolution. The display is based on the Fraunhofer's existing OLED-on-silicon technology, which up until now was used to create monochrome microdisplays.
Apple analyst Ming-chi Kuo says that Apple plans to launch its first AR headset in Q4 2022, powered by dual 4K OLED microdisplays, produced by Sony. The headset will feature Mac-level computer power and will not require a tethered smartphone to operate.
Apple has been working on AR technologies for many years. Last year it was indeed reported in Japan that Apple is working with Sony on its microdisplays. Earlier this year it was reported that Apple has teamed up with TSMC for microdisplay production - but it could be that TSMC will be the manufacturing partner, while Sony will provide the OLED technology and knowhow.
Oppo's Reno7 smartphone features a 6.43" 90z 1080x2400 AMOLED display, a Qualcomm Snapdragon 778G chipset, 8/12 GB of RAM, 128/256 GB of storage and a triple camera setup.
The Reno7 SE phone offers a similar display with different specifications, while the Reno7 Pro features a larger and brighter 6.55" 1080x2400 AMOLED display.
Last week we reported that Samsung Electronics plans to reveal its first QD-OLED TVs in early 2022. According to a new report in Korea, Samsung Display's first QD-OLED panels will be 65-, 55- and 34-inch in size. This means that in addition to Samsung's TVs, we are likely to see OLED monitors as well.
This is very good news to the consumers who have been waiting for OLED monitors for so many years. Some OLED monitors are already shipping - but only very high-end ones for professionals, such as LG's $3,999 31.5" UltraFine OLED Pro monitor.
