Abstract
A panel for use in a cathode ray tube of the present invention includes a face portion, a skirt portion extending from a periphery of the face portion and a blend round portion connecting the face portion and the skirt portion. A mold match line is formed on the skirt portion in a manner that a mold match line height H1 satisfies a first equation: 0<H1≦H×0.47 when mean outer radius of curvature is equal to greater than 10,000 mm, and satisfies a second equation: 0<H1≦H×0.37 when mean outer radius of curvature is less than 10,000 mm, where H is an overall height of the panel.
Claims2
A panel for use in a cathode ray tube, comprising:
- a face portion for displaying picture images, whose mean outer radius of curvature is equal to or greater than 10,000 mm;
- a skirt portion extending from a periphery of the face portion and having a seal edge sealed to a funnel;
- and
- a blend round portion connecting the face portion and the skirt portion,
- wherein a mold match line is formed on the skirt portion in a manner that a mold match line height H1 satisfies a following equation:
- 0<H1≦H×0.47
- where an overall height H is a distance between a first plane passing through the seal edge and a second plane passing through a center of the face portion, and the mold match line height H1 is a distance between the first plane and a third plane passing through the mold match line.
