Cambridge Display Technology (CDT) is the leading developer of technologies based on polymer light emitting diodes (PLEDs).
FOLED means Flexible OLED - built on flexible substrates (and not rigid glass). While the promise of flexible (and even rollable) devices is huge, there are no commercial flexible OLED displays available yet.
Low Temperature Poly Silicon a leading-edge manufacturing process for making TFT LCDs or AMOLED displays. Advantages of LTPS (compared to a-Si TFTs) include faster electron eesponse, dess connections & components and low power consumption and itegration of driver ICs onto the substrate
Organic Vapor Phase Deposition - an OLED production technology, which can reduce the cost and increase the efficiency of the OLED production process, developed by Universal Display. The OVPD production process utilizes a carrier gas stream in a hot walled reactor at very low pressure to precisely deposit the thin layers of organic materials used in OLED displays.
Phosphorescent OLED, a proprietary technology by Univeral Display, PHOLED use small molecule phosphorescent materials to create OLEDs.
Polymer light emitting diodes (P-OLEDs, or PLEDs). These OLED materials are made from large molecules (Polymers) and are suitable for solution-processing (ink jet printing, spin coating, etc). This technology was pioneered by Cambridge Display Technology.
TOLED means Transparent OLEDs, which can be used for displays (or lighting) in car windshields, windows, eyewear and even laptops or mobile devices.
Universal Display Corporation (UDC) - an OLED research, materials and IP company, holding many patents, including for phosphorescent OLEDs, and flexible and transparent ones.
