ABSTRACT:
In a pictorial display device containing a matrix of gas discharge cells in which discharge path is divided into an auxiliary discharge space for operation with low voltage, followed by a second space with short path length and high field intensity for accelerating the electrons, the cathode is subdivided into subcathodes with each of which a group of auxiliary anodes is associated to obtain a narrow, approximately wedge-shaped gas discharge which is fired and passed on line by line.
