Matrix excitation circuit for an oscilloscope display screen comprising a liquid crystal |
摘要 |
For the display of a phenomenon or a small number of phenomena by means of an oscilloscope comprising a liquid crystal display screen, a simple matrix excitation circuit is described wherein a time-division multiplex excitation with a great number of lines and a good contrast appears possible if for each column only one or a few picture elements must be set to the ON-state, costly provisions such as voltage and temperature stabilization being required.
