摘要: A colour cathode ray tube of the shadow mask or beam index type in which the screen structure applied to the faceplate (10) comprises a plurality of triplets of optical interference filter stripes (22) which are adapted to pass red (R), green (G) and blue (B) light produced by a homogeneous cathodoluminescent screen layer (24). The usual aluminium layer (26) may be applied to the screen layer (24). The optical interference filter stripes (22) may comprise short wave pass filters, band pass filters or a combination of both types. The short wave pass filter stripes may comprise modified quarter wavelength multi-layer dielectric filters and the bandpass filter may comprise a Fabry-Perot filter.
