Abstract : Alphanumeric characters can be formed on electroluminescent display panels consisting of individually controlled elements. Separate logic modules are used for each character to be generated, such that no information concerning the structure of the characters need be stored. The output of the character-generating modules is channeled to the appropriate position on the display panel. Each display module consists of 40 elements, arranged in 5 rows and 8 columns. The individual elements are actuated by applying voltages of opposite polarities to the corresponding x and y terminals. The display unit consists of three modules: the electroluminescent panel, the driver unit, and the character generating logic module. A single pulse from the computer control logic module initiates the formation of a character by opening a gate and admitting clock pulses into the character generating logic module. The clock pulses are used to actuate each row driver from 1 to 8 in succession. The corresponding column drivers are either actuated or inhibited by the outputs from the character generating logic module. Thus a number or a letter is formed by the luminescing elements at the intersections of actuated columns and the sequentially energized rows.
