ABSTRACT:
Display system using low energy electrons which are produced in the discharge of gases (plasma). For this purpose there is formed a matrix of cells each comprising a cathode, a glass block, hollowed out in its center for receiving a plasma of helium, an assembly constituted by an anode and a luminophore support separated by an insulator, and a grid wire coated with an insulator. The electrons of the plasma excite or do not excite the luminophore, depending on the potential applied to the grid which performs the function of a control electrode and storage element.
