P‐112: Sunlight Readable Bistable Electrowetting Displays for Indicators and Billboards

Abstract

adt's electrowetting displays are designed for bistability ("green") and capable of all backlight modes (reflective, transflective and transmissive). Compared to LED indicators, our pixels draw no power and are sunlight readable. Using CMY stacks we achieved a superior color gamut and high reflectivity (both topics are essential for electronic billboards).

62.3: Production Considerations for Bistable Droplet Driven Electrowetting Displays

“…As given in earlier papers [9], there is an intense interest to increase the number of layers in order to achieve a stacked CMY display with full color capability. We have realized some prototypes, but actually the reliable production of single layer products using existing equipment is our main focus.…”

An Electrochromic Displays Comprising The Three Primary Cyan Magenta and Yellow Colors Under Juxtaposed and Stacked Architectures

“…Currently, many non‐emissive technologies for active screens are being developed to obtain high‐performance color reproduction systems. Among them, cholesteric liquid crystals, [ 3 ] electrowetting, [ 4 ] interference filters consisting of micro‐electromechanical systems, [ 5 ] electrophoretic, [ 6 ] electrochromic [ 7 ] or thermochromic [ 8 ] technologies have been reported. In addition, these technologies have unique advantages such as non‐harmful reading and low power consumption, as the current trend is more and more toward electric mobility.…”
