ABSTRACT:
A waveform display including an opto electric display having m X electrodes and n Y electrodes arranged in a m x n element matrix. A series of m different reference binary codes are applied simultaneously one to each of the X electrodes. A waveform to be displayed is sampled and binary numbers representative of the amplitude of each sample are produced. These sample binary numbers are each converted into one of the reference binary codes for applications to the Y electrodes; the code so produced being related to both the amplitude value and the order of reference codes on the X electrodes. As a result of the simultaneous application of appropriate binary codes to each X, Y electrode, unselected X-Y intersections receive an rms voltage above a display threshold while selected X-Y intersections receive a zero voltage and collectively display the waveform.
The opto-electric display may be a liquid crystal display or an electro luminescent display. The binary codes may be an ordered series of binary numbers represented by logic zeros and ones, having a period T divided into N bits where m=2.sup.N, or period T divided into L bits and using 2.sup.N codes out of a possible 2.sup.L codes where L is greater than N and m=2.sup.N. Alternatively the binary code may be a pseudo random series of zeroes and ones.
