<p>An electronic analogue waveform display comprises a liquid crystal cell having x, y electrodes whereby the cell is addressed in a matrix manner by applying electric potentials of about zero at required x, y intersections and above a threshold voltage at all other intersections. A waveform to be displayed is divided into a series of amplitude samples and electrical potentials representative of these samples are applied to the y electrodes whilst a series of electric potentials is applied to x electrodes. Rectangular or sinusoidal waveforms may be applied to the x, y electrodes. Various circuits for producing a display are disclosed.</p> |
