Abstract
Electrowetting displays were first reported in 1981, several approaches were examined. However, ADT's "Droplet- Driven-Displays" technology is the only bistable one which makes them very attractive for energy-saving systems. That means that the power supply can completely shut off after changing the content and it will keep its information for years. More features that make the ADT approach very unique are paper like white appearance (even in the powerless OFFstate) and the capability for backlighting (most of the other e-paper technologies like electrophoretics can not be backlighted). Further achievements are a white state reflectance of about 70% resulting in sunlight readability and a pixel size in the range from 0.3mm to 10mm. Summarizing, ADT's electrowetting technology is highly suitable for lowest power (means eco-friendly or "green") displays.
