Researchers develop a novel memory device based on an OLED coupled with an MOS capacitor

Researchers from TU Dresden developed a novel memory device that is based on a combination of an OLED emitter and a metal-oxide semiconductor (MOS) capacitor.

The so-called pinMOS device is a non-volatile memory-capacitor with high repeatability and reproducibility. pinMOS devices can store several states, since charges can be added or removed in controllable amounts. This device can also be controlled (read and write) both electrically and optically.

UBI: high demand for rigid OLEDs may result in conversion of flexible OLED lines to rigid ones

UBI Research posted an interesting note. The company says that rigid OLED shipments (237 million) command a 79.2% market share of the entire OLED smartphone market, up from 64.5% in 2018.

Rigid vs flexible OLED glass area production (2017-2023, UBI Research)

Display makers have mostly invested in flexible OLED production - but currently there is higher demand for the lower cost rigid OLEDs. All rigid OLED lines are currently in full capacity and UBI suggests that we may see some companies converting flexible OLED lines to rigid OLED production - or that we'll see new investments in rigid OLED production.

Sharp's 6.18" flexible AMOLED displays are now available on clearance at the OLED Marketplace

Sharp started producing flexible OLEDs in low volume in August 2018, and have adopted these displays in its own smartphones. According to reports Sharp understands it cannot compete with Korean and Chinese companies with both technology and price and has halted smartphone OLED production (although it still develops advanced OLED technologies and will continue to produce OLEDs for other applications).

We now offer Sharp's flexible OLED displays at the OLED marketplace, at a clearance sale. These are high-end 6.18" 1440x2992 flexible AMOLED displays with on-cell touch, and we have 15,000 such panels available at a great price. Check out more information over at the OLED Marketplace, or contact us now.

Panasonic to halt all LCD panel production by 2021

Panasonic announced that it will stop all LCD panel production by 2021. Panasonic already stopped producing LCD TV panels in 2016, and current produces LCDs for automotive and industrial markets.



Panasonic says that even though its panels are highly regarded for their quality, the continuation of the business is enviable, as there is a "tougher environment" in the global market.

Idemitsu Kosan and Toray developed a red TADF/HF device that is the world's most efficient OLED emitter

Idemitsu Kosan and Toray Industries announced that the companies have jointly developed a red OLED device that is the world's most efficient emitter at 46 cd/A. The device uses a TADF emitter combined with red fluorescent materials (which likely means this is a HyperFluorescence device).

Idemitsu and Toray has been collaborating on OLED material development since 2017. This new device uses Idemitsu's TADF material combined with Toray's new red fluorescent material. The two companies say that this new material provides the same results as currently used red phosphorescent devices, and the plan is now to "drive forward to secure adoption of their materials" in mobile and TV applications.

Samsung researchers improve the efficiency and lifetime of self-emissive cadmium-free quantum dots

Researchers from Samsung's Advanced Institute of Technology (SAIT) developed a new method to increase the efficiency and lifetime of self-emissive Cadmium-free quantum dots. The researchers used Indium Phosphide QDs in a new structure that prevents oxidation and energy leaks and also absorbs current faster.

The researchers say that the new structure enhancements increases the internal quantum efficiency to almost 100 (the EQE reached 21.4%) while increasing the lifetime to a million hours (at a high brightness of 100 cd/m2). The maximum brightness is 100,000 nits. This performance is comparable to Cadmium-based QDs.
