Abstract
A waveform display comprises an opto electric display having m vertically electrodes and n horizontal electrodes arranged in an mxn element matrix. A series of n different reference binary code voltages V1-n are applied simultaneously, one to each x electrode. The waveform to be displayed is sampled and binary numbers representative of the amplitude of each sample are produced. These binary sample numbers are each converted into one of the reference binary codes and stored for application simultaneously 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 and Y electrode, unselected X Y intersections receive an rms voltage above a display threshold whilst selected X Y intersections making the waveform receive a zero voltage. 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 n = 2N, or period T divided into L bits and using 2N codes out of a possible 2L codes where L is greater than N and n = 2N. Alternatively the binary code may be a pseudo random series of zeros and ones. <IMAGE>
