Researchers from Jilin University developed a transparent glass display with a high white-light contrast ratio that is able to smoothly transition between a broad spectrum of color when stimulated with electricity. The technology overcomes hurdles that face existing electrochromic devices by capitalizing on the interactions between metal ions and ligands.
Electrochromic displays are able to continuously and reversibly manipulate the properties of light through the application of electricity. These devices have been proposed for use in a wide variety of applications, including in windows, electronic price tags, billboards, rear-view mirrors, augmented reality, and artificial irises. Current devices, however, tend to have low contrast…READ MORE
