Abstract: A method and system for defining a font character set for a display and for designing an electric writeable display using such a font character set is disclosed. A developer can create a font character set including a plurality of characters. The characters are overlapped within a bounded area in order to create a character mask. The character mask is composed of individual segments required to display one or more of the characters in the font character set. Activating one or more segments may display a character in the font character set. The method can be implemented in a system including a processor, a display, and a computer-readable storage medium containing instructions for one or more computer programs. Electrodes shaped and placed based on the segments of the character mask are used to implement an electric writeable display incorporating a font character set.
