Abstract
A method and device for providing a display having increased viewability are provided. The display assembly includes a backlight layer, an electrochromic layer formed over the backlight layer, a surface layer formed over the electrochromic layer and including at least one substantially translucent graphical element thereon, and a power supply. The electrochromic layer is switchable between a substantially transparent state and a substantially reflective state upon application of a switching voltage from the power supply, where the state being selected is based on a lighting condition of the display assembly.
