Abstract:

The results of a study, design and breadboard construction of a segmented Electroluminescent EL Symbolic Indicator are described. The equipment accepts a parallel 6-bit binary-coded input and converts the data into a symbolic readout on a 23-segment EL panel in response to an ADDRESS command pulse. Display capabilities include all the alpha-numerics, minus sign, plus sign and left and right slant bars. Data storage is implemented at the 23 segment-switching command lines so that a single code converter may be time-shared among many output display modules. The breadboard model of the EL Symbolic Indicator consists of two modules an output display module and a multiplexed code converter. The specifications for the breadboard model are given. The design and construction of the EL Symbolic Indicator using low-cost conventional components is described. Microminiaturization of the equipment and one possible approach to mechanization using standard off-the-shelf integrated circuit elements are considered. Author
