Abstract
The present invention includes an apparatus for and method of creating electrically modifiable images using a computer printer. In one embodiment, one or more ink reservoirs of a printer cartridge are filled with an electrochromic ink. The printer thus prepared can be used to print electrochromic patterns on a surface using standard ink application methods. In certain embodiments, more than one ink reservoir is filled with electrochromic ink. In these embodiments, separate reservoirs are filled with separate ink formulations so that the characteristics of the electrochromic pattern can be varied.
Claims10
An apparatus for creating a customizable electrochromic display comprising:
- an ink reservoir containing electrochromic ink;
- a print head connected to the ink reservoir in such a manner as to receive electrochromic ink from the ink reservoir;
- a print media holding mechanism disposed in such a manner as to hold print media at the proper position for receiving electrochromic ink from the print head;
- and
- a print controller connected to the print head or print media holding mechanism in such a manner as to control the relative position of the print head and print media.
