ABSTRACT:
The disclosure is of a system for operating a dot matrix display panel including elongated anodes and cathodes oriented transversely to each other to define columns of D.C. scanning cells. An array of quasi A.C. display cells is provided spaced from the D.C. scan cells by an apertured electrode plate. Operation of the D.C. scan cells to transfer glow from a scan cell to an associated display cell is achieved by momentarily turning off the scan cell by the application of a negative pulse to its anode. To prevent the coupling of this pulse to adjacent anodes and spurious operation of adjacent scan cells and display cells, a counter-balancing positive pulse is applied to all anodes. The preferred coupling circuitry includes coupling capacitors which can pass both of these positive and negative pulses.
