摘要

The electrowetting D~3 technology ("Droplet-Driven-Displays") was invented by ADT. Those displays have features like bistability and highest reflectivity, which offer unique application options for real "No Power ("green") applications ranging from indicators to billboards. This paper describes the fundamentals of D~3 EW displays (Passive Matrix, no Active Matrix needed) and system design incl. electronic driving using commercial ICs. We recently demonstrated all backlight modes (reflective, transflective and transmissive). Pixel size ranges from 0.5 to 10 mm and a wide temperature range is covered; color is realized by subtractive CMY stacks with printer-like gamut. The measurements of ambient light contrast ratio and color gamut clearly demonstrates the excellent performance of ADT's electrowetting displays for applications like "No Power" bistable LED indicator replacements and sunlight readable electronic billboards.
