ABSTRACT:
A gas discharge display device having a gas-filled space defined on one side by a front plate and on a side opposite thereto by a back plate and subdivided by a control plate into a gas discharge space and a post-acceleration space, the control plate carrying electrode runs including column conductors and anode row conductors forming a matrix having cross-points defining image points, a fluorescent screen disposed on the side of the front plate facing the control plate and defining the post-acceleration space, the fluorescent screen having an anode layer thereon, and at least one insulated cathode on the side of the back plate facing the control plate and defining the gas discharge space, and an auxiliary control plate having anode conductor strips on at least one side thereof that are parallel with the anode row conductors, the device including groupings of anode row conductors, each group thereof having M sequentially numbered conductors; groupings of anode conductor strips, each group thereof having N sequentially numbered conductors, each of the anode row conductors being aligned with a corresponding one of the anode conductor strips forming an aligned conductor pair; conductor pair selecting means for selecting each aligned conductor pair which includes simultaneously applying a respective selection potential to each conductor of an aligned conductor pair.
