Researchers develop an OLED-on-OTFT process to create high aperture wearable OLED devices

Researchers from China's Northeast Normal University developed a new integration strategy (called “discrete preparation-multilayer lamination”) that enables the deposition of OLED devices directly on top of OTFT transistors, to enable high-aperture wearable skin-patch OLED devices.

The new method starts with the preparation of the different layers on different substrates to avoid chemical and physical damage caused by process interferences, and then the transfer of the OLED devices onto the OTFT transistors. The researchers say that the resulting AMOLED display offers a high apreture ratio (83%), high mobility

RitDisplay to produce OTFT-driven AMOLED displays by 2026 in collaboration with Smartkem

UK-based OTFT display backplane developer SmartKem announced that it signed a collaboration agreement with based PMOLED-maker RiTdisplay, for the production of OTFT-based AMOLED displays. SmartKem further said that Innovate UK and the Taiwanese Ministry of Economic Affairs will support this project with a grant of around $530,000.

Smartkem will provide its proprietary OTFT materials to RiTdisplay to integrate within its OLED displays. If successful, the project will create the world's first commercially ready AMOLED display made using organic transistors, which will outperform RiT's PMOLEDs with higher brightness, lower power consumption and higher resolutions. Both companies hope that the project will be completed in 2026.

RiTDisplay and SmartKem join forces to develop OTFT-AMOLED displays

UK-based OTFT display backplane developer SmartKem announced that it has signed a joint development agreement with Taiwan-based PMOLED-maker RiTdisplay, for the production of OTFT-based AMOLED display prototypes.

SmartKem's technology could enable RiTDisplay to produce AMOLED displays at a lower cost, and, more significantly, to use its own PMOLED production line without the large investment needed for an LTPS AMOLED Line. The current agreement includes a prototype display development, it will have to be seen whether it will be expanded in the future for actual production.

OTFT developer SmartKem raised $24.6 million in a private placement

UK-based OTFT display backplane developer SmartKem has closed a $24.6 million private placement financing. Prior to the financing, the company also completed a reverse acquisition transaction with Parasol Investments Corporation (Parasol), a public Delaware corporation, whereby SmartKem became a wholly owned subsidiary of Parasol which later changed its name to SmartKem and will continue with the company's business as it is.

OLET developer Mattrix Technologies announces an additional $1.5 million investment by JSR

Organic-TFT backplane/emitter developer Mattrix Technologies (previously nVerPix) announced that it has received a $1.5 million investment from JSR Corporation. This second investment by JSR is the first tranche in the company's new round (which will total, hopefully, $3 million)

JSR is a strategic investor, and has also launched a joint-development project for the development of solution-based conductive inks that will be sued in Mattrix's next-generation backplane transistors.

OLET developer Mattrix Technologies raised $3 million

Organic-TFT backplane/emitter developer Mattrix Technologies (previously nVerPix) announced that it has closed its Series A financing round, with $3 million in investment from Samsung Ventures and JSR Corporation.

Mattrix Technologies, spun-out of the University of Florida in 2011, developed the world's first full-aperture OLET (organic light emitting transistor) display technology, based on the company's proprietary CN-VOLET (carbon-nanotube enabled, vertical, organic, light emitting transistor) technology, a new pixel architecture that combines the drive transistor, storage capacitor and light emitting layers into a sequentially deposited, vertical, transparent stack. The company is also looking into graphene electrodes as an alternative to CNTs.

Researchers from Italy develop a graphene-based OFET for future OLED and OLET backplanes

Researchers from Italy's ISOF-CNR, University of Naples "Federico II" and Università di Modena e Reggio Emilia have developed new organic n-type FET transistors based on CVD graphene sheets. The researchers say that the new process and materials they used can enable flexible, transparent and short-channel OFETs - which could be used in the future for OLED or OLET displays.

To create the new transistors, the researchers used thermally evaporated thin-films of PDIF-CN2 (a perylene diimide derivative, specifically Flexterra's ActiveInk N1100) as the organic semiconductor for the active channel of the transistor, with the single-layer CVD graphene (grown at Italy's IIT INSTITUTE) as the electrode material

Novares invests 5 million Euro in FlexEnable, to help bring OLCDs to the automotive market

FlexEnable announced that Novares, a plastic automotive solutions provider, invested €5 million in the company. This is a strategic investment by Novares that aims to bring FlexEnable's flexible organic LCD (OLCD) to automotive interiors.

Interestingly the press release does not discuss OLEDs at all, only OLCDs which is described as a low-cost, high-reliability, conformable and shapeable display technology. FlexEnable started commercializing its OLCD technology together with Truly Semiconductors in 2017. OLCD production is expected to begin by the end of 2018, and Novares already demonstrated a demo Car that features OLCD displays
