Independent claim 1 is illustrative of the invention and is reproduced below:
1. A method of manufacturing color filters on a luminescent
screen assembly for a color cathode-ray tube (CRT), comprising:
providing a faceplate panel having a patterned
light absorbing matrix thereon defining a set of first fields,
a set of second fields and a set of third fields;
forming a first photosensitive blocking layer over
the set of second fields and the set of third fields:
applying a first color filter to the set of first fields;
heating the faceplate panel to a first temperature;
removing the first photosensitive blocking layer
from the set of second fields and the set of third fields;
heating the faceplate panel to a second temperature;
forming a second photosensitive blocking layer over
the set of third fields and the first color filter in the set of
first fields;
applying a second color filter to the set of second
fields;
heating the faceplate panel to a third temperature; and
removing the second photosensitive blocking layer
from the set third fields and the first color filter in the set of
first fields.
