    Abstract: The screen has a cathode composed of microdots (2) for electron bombardment of an anode (5) provided with luminophores (7) of the primary colours on strips (9) of indium-tin oxide deposited on the glass (6). The strips are separated by insulation (20) whose surface (21) has a secondary emission coefficient less than 1 at least within the range of primary electron energies. Each insulating strip of e.g. silicon dioxide has sufficient resistivity to prevent breakdown between two neighbouring luminophores. Its surface may have a coating of low-emission material (e.g. silicon) to a thickness of about 100 Angstrom with a gap of 5-10 mu m at each edge.

    Abstract: The anode includes electrode bands (17) each of which incorporates a resistive band (18) which is a transparent electrically conducting non-stoichiometric oxide, esp. indium tin oxide, fixed by the quantity of oxygen contained in the oxide. Associated with each band are two parallel polarisation bands (19) on either side and joining to the conductor connecting the electrodes. Phosphor bands (7) are deposited onto the resistive bands. The polarisation and resistive bands may be of the same material but with the polarisation band having lower resistivity. An insulator (8) separating the electrode bands serves as a mask to increase the resistivity of the resistance bands by heat treatment in an atmosphere of oxygen. Alternatively, the thickness of the material may vary the resistivity with the insulator acting as a etching mask. Three such assemblies are used to mfr. a colour screen.
