Plexcore(R) Printable Ink Improves Performance in Advanced Polymer OLED Devices
technology company that specializes in printed solar, lighting and other
organic electronics — announced today that its conductive ink has been shown
to improve the performance of certain P-OLED devices. P-OLEDs (Polymer Organic
Light Emitting Diodes) are a fast growing, new generation of display
technology, which promise to replace liquid crystal displays (LCDs) in many
existing applications in the coming years, as well as create exciting
possibilities for new product forms such as flexible or even wearable
Plextronics requested an independent validation of test data obtained from
its Plexcore(R) Organic Conductive (OC) ink by Cambridge Display Technology,
Inc. (CDT) — a subsidiary of Sumitomo Chemical Co. Ltd. Data produced by CDT
on Plextronics’ behalf show improved P-OLED operating voltages and voltage
stability compared to other solution processed HIL alternatives that have been
For blue P-OLED test devices, a two volt reduction in initial operating
voltage was achieved with improved voltage stability over the lifetime of the
devices (less than 0.5V increase), a significant improvement over other
solution processed HIL alternatives that have been previously reported.
Improving voltage characteristics in P-OLEDs is critical to reducing the power
consumption of these devices, while maintaining or improving device lifetimes.
for mobile display applications, such as cell phones and mp3 players. We are
pleased to see Plextronics making significant progress on HILs and developing
materials that bring such voltage improvements to P-OLED devices.”
“With its Plexcore(R) OC ink, Plextronics brings a technology platform
that can be tuned to meet the needs of CDT’s specific device architecture,
with the potential to enable improved energy efficiency and lifetime in its
P-OLED devices,” said
About Plextronics, Inc.
Plextronics, Inc. is an international technology company that specializes
in printed solar, lighting and other organic electronics. Headquartered in
emitting diodes (OLED), specifically the conductive inks and process
technologies that enable those and other similar applications.
With a company vision of enabling 15 billion printed electronic devices by
2015, Plextronics is creating technology capable of commercial-scale
manufacturability and performance. The company’s device design, process
technology and Plexcore(R) branded inks enable the formation of active
electrical layers — the key drivers of printed electronics.
The privately held company was founded in 2002 as a spinout from
refined and further developed this technology to deliver exceptional
performance for printed electronics.
Specific to the Plexcore(R) OC ink, it is a multi-functional conductive
material compatible with a number of printing techniques including
spin-coating, ink jet printing, and contact printing. The inks are
customizable to possess a wide variety of film properties, dependent upon its
desired function and performance requirement.
The inks are ideal for integration into various printed electronic
applications. They can be tailored to the specific needs of a given
application and meet the stability needs required for high volume

Cambridge Display Technology (CDT), headquartered at Cambourne near
Cambridge in the UK, was spun out of
by Sumitomo Chemical,
the research and commercialization of light emitting polymer technology used
in displays and lighting applications.
Devices incorporating this technology are often referred to as P-OLED, or
polymer organic light emitting diode, devices. CDT holds an extensive patent
and know-how portfolio relating to P-OLED materials and devices and actively
licenses this portfolio to display and lighting companies around the world.
CDT and Sumitomo engage in a wide range of Organic Electronics activities such
as organic thin film transistor (OTFT).
