Technology Development Centre
CDT maintains a state of the art research and development facility at Godmanchester in Cambridgeshire. At the Technology Development Centre (TDC), a team of scientists and engineers has access to a 900 m² facility with 640 m² of cleanroom, and is engaged on projects in the following fields.
- Development of the display manufacturing development
- Printing process and ink formulations for partners
- Novel anode, cathode, and device architecture development
- Development of printing techniques for solution processing of displays and solution formulation
- Examples include surface energy patterning and alternative printing techniques
- Ink development and formulation, including quality measurement of materials and new inks
- P-OLED test cell fabrication and testing
- Highly flexible 6-inch research line with capacity to produce approximately 1300 devices per week
- Continuous process improvement to reduce lifetime variance, improve yield and increase throughput
- Prototyping
- Display backplane development
- Lighting and organic semiconductor (OSC/OTFT) device prototype production

Materials Research Centre
In Cambridge, CDT scientists work on a range of activities from developing a fundamental understanding of the chemistry and physics of displays through to optimising materials for use in real applications.
The Materials Research and Development team is responsible for:
- Design and synthesis of novel materials for development projects:
- High efficiency, deep blue materials for displays, including phosphorescent blue for displays and lighting
- High efficiency white lighting materials
- Transport layers
- Development and support of external collaborations for novel hole and electron transport materials and their optimisation
- Device physics, analytical support
- Fundamental understanding in polymer architecture and design improvements in scalable synthesis
- Fundamental understanding of degradation mechanisms in materials and devices
- Analytical support of all core projects, including state-of-the-art capability development to support materials projects
