Casestudy Summary

The objective of this case study was an investigation of the eco-efficiency potential of new nanotechnological products currently being developed for the display industry. For this purpose, OLED and CNT FED displays were compared with conventional CRT, LCD, and plasma displays.

Due to differing stages of development of the technologies under investigation, the resulting eco-efficiency potential assessments come with a certain degree of uncertainty. In the overall product life cycle, the manufacturing phase is responsible for an ever increasing share of the environmental impacts. The successful implementation in mass production of the material and energy efficiency increases offered by OLEDs will make it possible to realize significant eco-efficiency potentials. At the very least, a 20% savings in energy as compared to LCDs over the entire product life cycle should be possible.

Likewise, development of the eco-efficiency potential of the CNT FED will become possible once the manufacturing process, particularly in the highly complex production of nanotubes for field emitters, becomes as efficient as current processes. Risk potentials from these new technologies are unlikely.
