PATTERN GENERATING SYSTEMS

摘要

A pattern generating system for use with a display device including a matrix electrode assembly comprises a plurality of pattern signal generators for displaying different patterns on the matrix electrode assembly. Means is provided to selectively drive one of the plurality of pattern signal generators for displaying a selected one of the patterns or simultaneously driving a plurality of pattern signal generators for displaying modified patterns on the matrix electrode assembly by synthesizing different patterns. Alternatively, a partial pattern signal generator is added which is driven concurrently with one of the plurality of pattern signal generators for displaying a modified pattern.
