Abstract
This invention deals with an arrangement for incorporating a cursor feature into a plasma shift register display panel having a plurality of display channels. The cursor arrangement of the present invention is implemented by incorporating a separate cursor channel into such a display panel. The cursor channel is filled with an ionizable medium and has input, transfer and erase electrodes positioned on opposing walls thereof. The transfer electrodes are in turn arranged into four groups with two of the groups of electrodes being shared with the display channels of the panel. Through the synchronous application of suitable voltage potentials to the input, transfer and erase electrodes associated with the cursor channel, it is possible to input and transfer light dots through the cursor channel without having to regenerate the material being displayed by the panel and without fear of destroying the displayed material.
