Title:
COLOR CATHODE-RAY TUBE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2003022759
Kind Code:
A
Abstract:
To provide a color cathode-ray tube which has improved image contrast and purity drift characteristic by absorbing heat by collision of an electronic beam to a shadow mask efficiently.
The color cathode-ray tube has a panel which a fluorescence face and a reflective film are formed in the inside, and it is constituted with forming a high heat-absorption thin film, comprising carbon substantially, by sputtering on the above reflective film.
