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.

Mattrix says that its technology can increase OLED efficiency by more than 10%, while doubling the lifetime of the materials. The technology also enables larger emissive aperture, which enables brighter displays.

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.

We have talked to the company in the past and updated on the technology back in 2013. In SID DIsplayWeek 2018 the team presented a working mono-color (green) 320x240 2.5" display. The aperture ratio was 70% and the brightness is over 500 nits.
