At etulipa we are transforming the world of outdoor digital advertising! We create billboards that read like paper, but offer all the advantages of digital: real-time, targeted, still and video, on-the-spot advertising. All that without light pollution and using 100 times less power than LED billboards! Watch how it works: https://www.youtube.com/watch?v=7u-Za-X7JsY (2.28 min.)Our revolutionary technologyThe etulipa displays are not made up of pixels powered by LED lights, but of cells containing three layers of colored oils that reflect sunlight. At the heart of our solution is a revolutionary display technique, called electrowetting. A low voltage is applied to cause the oil to spread or contract in the cells, thus forming the full color image. The result is a highly energy-efficient display that reads like paper but with the possibilities of an LED screen!
