Abstract
A collector printing process is utilized for applying thermoplastic pressure-sensitive inks, corresponding to the color TV phosphors and the black matrix, onto the inner face of the TV panel. Separate inks, formed of inorganic pigments and a thermoplastic pressure-sensitive medium, are each separately patterned. The separate inks are then printed in registration onto a collector to form a composite pattern. Upon completion, the composite pattern is completely transferred to the TV panel by contact of the collector against the inner panel face to form the target.
Claims9
A method of producing a target for a color TV panel, the target formed of a composite pattern of a black matrix and respective red, blue and green color phosphors comprising the steps of:
- formulating a separate composition of thermoplastic, pressure-sensitive ink for each of the black matrix and color phosphors, said inks exhibiting cohesive strength and pressure sensitivity at near room temperature;
- forming each composition into a corresponding separate pattern;
- establishing the black matrix and respective color phosphors in the separate patterns on separate surfaces;
- completely transferring and registrably combining the separate patterns into the composite pattern onto at least one collector;
- and completely transferring the composite pattern from the collector to the panel to form the target thereon.
A method of producing a target for a color TV panel formed of separate patterns corresponding to a background matrix and respective color, phosphors comprising the steps of:
- establishing separate thermoplastic ink patterns of each of the background matrix and color phosphors onto separate surfaces, collecting the separate patterns in registration onto a common surface as a composite pattern;
- and transferring the entire composite pattern onto the panel by intimate contact of the common surface and the panel in a single pass for forming the target on the panel.
