Early last year, Samsung showcased its Color ePaper display, a breakthrough technology that consumes almost no power. The South Korean firm announced today that it will showcase a 20-inch Color ePaper display for the first time. The Color ePaper display consumes just 0.005 W of power when showing static images. Users can control it using the Samsung E-Paper app, which is available on Android and iOS devices. These features make the Color ePaper display well suited for retail stores, indoor advertising, and even classrooms.
