High density electrochromic display |
摘要 |
An electrochromic display and a method for making thereof are disclosed. The display has isolated and perforated reflectors separating an electrolyte confined between two electrodes. The front electrode is transparent. The reflector eliminates the need to include pigment particles in the electrolyte to mask the black rear electrode and to provide a desired color background. The pigment free electrolyte is thinner than a pigmented electrolyte. The reflector reflects light back to the transparent electrode thus masking the rear electrode and providing a background color other than black. When the rear electrode is driven by a drive circuit, ions of the electrolyte and current pass through the reflector towards the front electrode, where a coloration reaction occurs to form an image. The electrochromic display is thin, has high resolution, and does not exhibit image spreading and distortion.
