About the Company

Solchroma Technologies is a venture-backed company that builds full color, reflective digital displays for the smart cities of the future.

About the Solution

Solchroma has 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 filter chambers. 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.

The company’s system produces a vivid, dynamic, and reflective display that does not require an internal light source and consumes only one percent of the energy of existing LED-based digital signage.
