Abstract
Outdoor displays become rapidly digital in our digital world. These digital displays are typically emissive, implying a very high‐power consumption to be seen in the daylight, and light pollution in nighttime. Last year Etulipa announced and demonstrated a full colour reflective display based on Electro Wetting Display technology with 10mm pixel pitch. The vertically stacked Cyan Magenta Yellow architecture yields very bright colours. The high switching speed of electrowetting cells enable displaying of video content. The power consumption is 7 W/m 2 implying that the displays can run on solar systems without any need for charging from the grid. The market feedback consists of several exciting applications which are reviewed. Street furniture is expected to be a very early application. Because the typical viewing distance for street furniture applications will be in the order of meters, the pixel pitch should be in the order of millimeters. This requirement defines a technical roadmap for development of the existing electrowetting architecture.
