<p>In a direct current gas discharge panel, the cathode conductors (4) are protected from ion bombardment by a refractory oxide (MgO) double isolating layer (10, 12) the outer portion (10), from 2,000 ANGSTROM to 3,000 ANGSTROM thick, being doped with from 10%to25% by volume of a noble metal, the inner portion (12), from 100 ANGSTROM to 10,000 ANGSTROM thick, being not so doped. The anode conductors (6) may be isolated by a single layer (13) which may be non-stoichiometric and effectively form a resistive part of the circuitry of the panel. </p> |
