Abstract (en)

[origin: EP0802559A1] The screen has a cathode composed of microdots (2) for electron bombardment of an anode (5) provided with luminophores (7) of the primary colours. The source of progressive emission is a resistive coating (11) of hydrogenated silicon or its carbide, nitride or oxide, or hydrogenated carbon or germanium. An alternative source comprises a number of insulating strips or tracks (8) which separate the luminophores on the anode side of the evacuated space (12). Either source may be formed by plasma-enhanced chemical vapour deposition with controlled temperature, pressure or self-bias voltage.
