Abstract: Two waveform traces to be simultaneously displayed are sampled and converted to a series of digital samples values. An electro-optic display (1), e.g. a liquid crystal or electro luminescent display has a first m set and a second n set of electrodes arranged in a matrix having m x n display elements. The matrix may be in cartesian XY or ⊖ polar co-ordinate format. In one form the m set of electrodes are arranged in two sub sets alternating with one another forming a sub set m o  of odd rows and a sub set m e  of even rows. Coded waveforms V,, each having a different shape over a period T are applied to one sub set m o  of the m electrodes whilst another voltage is applied to the other subset m e  of m electrodes followed by application of V i  to the sub set m e  and the other voltage to sub set m o . Selected ones of the coded waveform V i  are generated and applied to the n electrodes, the choice of such selectively produced waveforms being related for each successive n electrode to successive sample values of the two traces and the order of coded waveforms on the m set of electrodes. As a result traces are displayed at interesections where the same waveform occurs periodically and simultaneously. 
     The coded waveforms V i  applied to the m electrodes may be produced by a pseudo random generator (24, 25). The selected ones of the coded waveforms V i  applied to the n electrodes may be produced by a read only memory (50) supplied with trace sample values stored in a random access memory (28). 
     A priority encoder (36, 38 to 46) modifies each sample value of the traces as necessary to ensure that two values for any given n electrode do not appear on the same subset of m electrodes.
