ABSTRACT:
A display system employs electronic components for deriving and supplying display control signals, preferably in the form of multi-bit display control words, to control a display device. The display device is formed of a plurality of individual display units preferably arranged in horizontal rows and vertical columns. Each of the display units is controlled by at least one bit of a multi-bit display control word. Each vertical column of the display device is collectively controlled in whole or in part by one multi-bit display control word. Control and memory elements control the display device in accordance with a plurality of display control words received. The intensity of the display units is controlled by energizing the units in predetermined fractions of the periods of the periodic waveform which energizes the display units. The system includes a system memory for recording and holding a plurality of display control words which define a selected pattern or patterns to be presented. The system may include means for repetitiously accessing in sequential order the display control words defining the pattern, thereby allowing the pattern to be repetitiously presented upon the display. A pattern composition means logically combines two preexisting display control words in separate memory locations and supplies the new display control word resulting from the combination to a third memory location. The composition means is thereby operative to combine a plurality of patterns defined by selected groups of display control words in memory.
