MULTINUMERIC DECODER FOR DOT MATRIX DISPLAYS

A simple and self controlled multinumeric decoder-driver for dot matrix displays is proposed. A multinumeric display system using this decorder displays the decimal digit of the BCD input in any one form of eight different languages. The circuitry of the decoder is simple but its capability is versatile. With a little additional hardware, the display system could easily be expanded to provide the display of digits in many more languages. Also, a single multinumeric decoder accepting four BCD inputs and driving four dot matrix display devices is reported.
