Abstract
A control plate for a gas discharge display device has a mechanically stable carrier plate of an electrically insulating material which has metallized column conductor tracks on one side and metallized row conductor tracks on an opposite side which in combination form a matrix of perpendicular rows and columns. The carrier plate has perforations extending through plate at points of intersection of the rows and columns. Each row and column is separately energizeable for selected transfer of electrons in the display device from one side of the plate to the other. The metallized tracks on each side extend a distance into the perforations so as to prevent charge accumulation within the perforations which would otherwise impair the control obtainable by the plate. The metallized portions of the perforations are separated by a ring of exposed carrier plate which is substantially nonconducting having a resistance of 100 megaohms or greater.
