Solchroma Technologies is a venture-back company that builds full color, reflective digital displays for the smart cities of the future. They have developed a proprietary system of electroactive polymer actuators, configured as hydraulic pumps, that move colored ink from reservoirs behind a pixel surface into separate, viewable color filterchambers. Ambient light is selectively absorbed through layered CMY color filters and reflected back to the viewer, where greyscale is achieved by varying the amount of CMY ink in view.
