Abstract:
The present disclosure provides apparatus and methods for multi-color electrochromic devices. In one embodiment, pixels of a first color electrochromic material (i.e. pigment) are arranged in first areas on a substrate with pixels of a second color electrochromic material in second areas to define a two-dimensional pattern of the first and second color on the substrate. When the applied electric field or current supplied to each pixel is changed, the device may produce the respective colors of the electrochromic materials and may produce a blended color because of the arrangement of the pixels. In accordance with further aspects of the disclosure, the electrochromic materials may form a design, pattern, logo, or picture when the electrochromic materials are activated. In yet further aspects of the disclosure, a substrate is masked and unmasked as a plurality of colors are applied to the substrate to produce a multi-color electrochromic display.
