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.
The Realme GT smartphone features a 6.43-inch 1080x2400 120Hz Super AMOLED display, a Snapdragon 888 chipset, 8/12 GB of RAM, 128/256 GB of storage, a triple camera setup and 5G connectivity.
The Realme GT will ship by the end of March 2021 starting at around $500.
The Meizu 18 smartphone features a 6.2-inch 1440x3200 (563 PPI) 120Hz 1,300 nits Super AMOLED display, a Qualcomm Snapdragon 888 chipset, 8/12 GB of RAM, 128/256 GB of storage, a triple camera setup and 5G connectivity.
The Meizu 18 Pro offers a larger display at 6.7-inch but otherwise with the same specifications. There's also a quad-camera setup and a larger battery.
The Vivo S9 smartphone features a 6.44-inch 1080x2400 90Hz HDR10+ AMOLED display, a MediaTek 1100 6nm chipset, 8/12 GB of RAM, 128/256 GB of storage, a triple camera setup and 5G connectivity.
The S9 will launch by the end of March 2021 starting at around $470.
According to a report from Korea, LG Electronics have lowered the price of its new OLED TV models by around 20%, compared to last year prices - in order to stay competitive and increase the demand.
The 2021 65-inch OLED evo G1, for example, is priced at 4.6 million Korean Won ($4,090 USD), which is 17.9% lower than the price of the 2020 65" OLED GX model at launch (5.6 million Won). The rest of the 2021 OLED TV models are offered at similarly lower prices.
Researchers from Dresden's Technical University (TUD) developed a new OLED device structure that combine vertical organic permeable base transistors (OPBT) and OLEDs materials - organic permeable base light-emitting transistor, or OPB-LET.
The new design successfully combines the function of a highly efficient switching transistor and an organic light-emitting diode. The OLED transistors (OLETs) are three-terminal devices combining a thin-film transistor with a light-emitting diode. Unlike previous OLETs, the OPB-LET offer high performance, thanks to the permeable base electrode located at the center of the device. The electrode forms a distinctive optical microcavity and so regulates the charge carrier injection and transport.
China-based OLED maker Visionox has spun-off its PMOLED business, to create a new company called Qingyue. Visionox will not focus on AMOLED production (after having spun-off its OLED lighting unit Yeolight back in 2015).
Qingyue, which is one of the world's leading PMOLED makers, has two 370x400 mm production lines, each with a capacity of 8,000 monthly substrates (around 1.75 million 1” displays).
PPG Industries and Universal Display established a strategic relationship in 2000, and since then PPG is the exclusive producer of UDC's PHOLED emitter materials. The two companies announced that they will establish a new manufacturing site in Shannon, Ireland, for the production of UDC's emitters.
The new facility will double the production capacity of UDC's OLED emitters at PPG, and will also diversify the company's manufacturing base. UDC leased the Ireland site (which, up until now, was producing pharmaceutical intermediates) and will adapt it to PHOLED production. Facility improvements and regulatory approvals are expected to be completed in the next 12 months, and operations are scheduled to commence in early 2022.
