Description
Summary:We have developed 32‐inch and 36‐inch Wide CRTs upon that iron tension masks are mounted for the first time as the masks are of corner suspension system. The corner suspension system has their main purpose of mechanical compensation, and the design makes compatibility between doming compensation and drop property possible. Adoption of the tension mask enables not only smaller variable pitch from center to periphery and higher peripheral resolution, but also smaller difference in thickness between the center of panel glasses and their periphery as well as adoption of tinted glasses. Moreover, with the improvement of spot size of electron guns, SVM sensitivity, prevention of cone‐halation, and others, a drastic improvement in resolution and contrast has been achieved.
