A selection system for a gas discharge display panel

Display panels which are inherently coordinate selection devices are ideally suited to provide graphical output for digital computing machines. In order that digital information may be written on such a display panel, rapid access must be provided to a large number of coordinate lines. The selection system described in this paper employs submatrices of linear transformers selected by low-power transistor circuitry and provides pulses of defined voltage of either sign and of specified duration. The system was specifically designed for a 1024 × 1024 gas-charge display panel, which will be briefly described, but could be useful for other displays requiring voltage-selection.
