Abstract
Abstract 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.

Claim 1
Independent Claim

A pattern generating system for displaying matrix patterns of a character font on a display device including a matrix electrode assembly, and means controlling said assembly comprising a plurality of selectively operable whole pattern character signal generators for displaying different respective whole patterns of less than the total number of characters in said font, a partial pattern signal generator, means for independently driving said whole pattern character signal generators for displaying selected ones of said whole patterns, and means selectively operable for simultaneously driving a selected one of said plurality of whole pattern character signals generators and said partial pattern generator to display a composite modififed pattern by said matrix electrode assembly of characters in said font not provided by said whole pattern character signal generators.
Claim 2
Dependent Claim
126 words
A pattern generating system for displaying matrix patterns of a character font on a display device including a matrix electrode assembly, and means controlling said assembly comprising a plurality of selectively operable whole pattern character signal generators for displaying different respective whole patterns of less than the total number of characters in said font, a partial pattern signal generator, means for independently driving said whole pattern character signal generators for displaying selected ones of said whole patterns, and means selectively operable for simultaneously driving a selected one of said plurality of whole pattern character signals generators and said partial pattern generator to display a composite modififed pattern by said matrix electrode assembly of characters in said font not provided by said whole pattern character signal generators.
Claim 3
Dependent Claim
122 words
A pattern generating system for displaying matrix patterns of a character font on a display device including a matrix electrode assembly, and means controlling said assembly comprising a plurality of selectively operable whole pattern character signal generators for displaying different respective whole patterns of less than the total number of characters in said font, means for driving a selected one of said plurality of whole pattern character signal generators for displaying a selected whole pattern, and means selectively operable for simultaneously driving a plurality of said whole pattern character signal generators for displaying a composite modified pattern by said matrix electrode assembly by synthesizing different whole patterns of characters in said font not provided by said whole pattern character signal generators individually.
Claim 4
