Abstract
Semi-flat CRT panel having relations of Ryi<Rdi<Rxi and 2×Ryi<Rxi, where Rxi denotes an inside surface horizontal curvature, Ryi denotes an inside surface vertical curvature, Rdi denotes an inside surface diagonal curvature for a CRT with an aspect ratio of 4:3 and an outside surface diagonal curvature Rd is greater than 30,000 mm, whereby securing a strength of the semi-flat CRT panel, eliminating a distortion of image, and reducing reflection from an external light.
Claims8
A semi-flat CRT panel comprising:
- a substantially flat outer surface;
- and
- a spherical inner surface having relations of Ryi<Rdi<Rxi and 2×Ryi<Rxi, where Rxi denotes an inside surface horizontal curvature, Ryi denotes an inside surface vertical curvature, Rdi denotes an inside surface diagonal curvature for a CRT.
A CRT panel comprising:
- a substantially flat outer surface;
- a spherical inner surface having relations of Ryi<Rdi<Rxi and Ryi/Ye>7, where Rxi denotes an inside surface horizontal curvature, Ryi denotes an inside surface vertical curvature, Rdi denotes an inside surface diagonal curvature, and Ye denotes ½ of a vertical length of an effective surface of the flat CRT panel.
