Cambridge Display Technology, Ltd.

Company Overview

CDT is the leading developer of technologies based on polymer light emitting diodes (P-OLEDs).  P-OLEDs are designed for use in the latest generation of electronic displays and in lighting products, offering many advantages over the liquid crystal displays (LCDs) and plasma displays used in flat panel televisions.

CDT is the originator of polymer based OLEDs and has a heritage with a direct line back to the original discovery of organic electroluminescence from polymers at Cambridge University.

Today, as part of the Sumitomo Chemical Group, CDT is a globally respected organization running collaborative projects with many global consumer electronics companies, as well as with leading academic research institutions.

Increasing demands in the display and lighting markets drive our ongoing program to develop materials for brighter, faster, longer life panels. Sophisticated techniques developed at CDT allow us to maximize the performance of P-OLED materials and devices. Our ability to take formulations through to prototypes and to demonstrate manufacturability is key to our support of the supply chain.

Our technology is available to today’s product designers, enabling them to create generations of consumer and business products, with exciting new levels of performance.

CDT owns key intellectual property around P-OLED materials, devices and processes, such as inkjet printing, which are used in the manufacture of P-OLED displays. CDT has over 560 patents granted worldwide in 280 families.

CDT is also supporting Sumitomo’s future goals by developing the next generation of innovative new technologies to enhance existing business or create new opportunities for Sumitomo.  This includes fundamental research in areas such as biosensors and printed electronics and, as one of Sumitomo Chemical’s corporate research laboratories CDT identifies and researches new technologies in the fields of information technology, life sciences, healthcare, energy and the environment.

Facilities and Capabilities

CDT has state of the art research and technology development facilities in Godmanchester, near Cambridge, UK.

Our facilities include synthetic chemistry laboratories, formulation and printing laboratories, chemical and physical materials analysis, electrical and optical device measurement, fast laser spectroscopy, and clean room facilities.

The team of Scientists and Engineers in our Research and Technology Development Centres are engaged in projects investigating a range of cutting edge activities including Displays, Lighting, Integrated Printed Electronics, and New Technologies.

CDT works closely with Sumitomo’s research laboratories in Tsukuba, Japan to enhance P-OLED materials, device and process research, and OTFT and OPV research and development.  CDT also works closely with Sumitomo’s Device Development Centre in Ehime, Japan to support P-OLED panel production and process development.

Our Story

CDT was founded in 1989 in the Cavendish Laboratory of Cambridge University.  It was here that a research group made the initial discovery that light could be produced from conjugated polymers.  CDT was founded by Cambridge University and seed venture capital, prior to being sold to US private equity groups in 1999.

In 2001, Sumitomo took its first license to CDT materials and made its first investment in CDT.

In 2002, the first high-profile commercial PLED product was launched, an innovative shaver with an electronic display from Philips which featured in the James Bond movie ‘Die Another Day’.

In 2004, CDT floated on the NASDAQ.

In 2005, Sumitomo acquired Dow Chemical’s P-OLED assets and Sumation™, a joint venture with CDT, was established with CDT for the development and production of materials and inks.

CDT and Sumitomo’s long term partnership culminated in Sumitomo Chemical Company’s acquisition of CDT on 19 September 2007.
