Two simple bar matrix display formats for alphanumeric English characters

Two novel and very-simple bar matrix layouts having nine segments (plus a dot) and ten segments (plus two dots), respectively, for displaying English alphanumeric characters are proposed. The displays involve simpler interfacing circuits and consume less power than the 14-segment and 16-segment displays being presently used. The proposed layouts can be implemented in the form of display modules using easily manufactured LEDs (light emitting diodes) or LCDs (liquid crystal displays). The layouts are also suitable for CRT (cathode-ray tube) displays because they require very simple X- and Y-deflection waveforms.<
