Panel for slim cathode ray tubes

Abstract

Disclosed herein is a panel of a slim cathode ray tube constructed such that the deflection angle of an electron beam is 110 degrees or more. The slim cathode ray tube includes a tube part constituted by joining the panel and a funnel with each other. The panel includes a face part, a side wall disposed around the face part such that the side wall is bent toward the funnel, and a seal edge formed at the side wall, the panel being joined with the funnel at the seal edge. On the assumption that the thickness of the center of the face part is Tc, the thickness of the long side of the seal edge is Tx, the thickness of the short side of the seal edge is Ty, and the thickness of the diagonal part of the seal edge is Td, the panel is constructed such that the following inequalities are satisfied: 0.8<=Tc / Ty<=Tc / Tx<=1.0<=Tc / Td and Td H01J 29 / 86 H01J 29 / 18 5 16 2 2006 / 2 / 8 1822301 2006 / 8 / 23 000000000 LG Philips Displays Korea Korea Hong Byong G.

Description

technical field [0001] The present invention relates to a thin type cathode ray tube, and more particularly, the present invention relates to a display screen for a color cathode ray tube, wherein the center thickness of the display screen and the thickness of the sealing edge can be appropriately set, and can be appropriately set The outer edge corner of the display screen, so as to minimize the stress concentration caused by the increase of the deflection angle, ensure sufficient rigidity, improve the anti-riot characteristics and plasticity of the display screen, and effectively prevent the reinforcement belt from slipping. Background technique [0002] In general, a cathode ray tube is a device for converting electrical signals into electron beams and scanning the electron beams across a phosphor screen to display images on a display screen. [0003] FIG. 1 is a partially cutaway side view showing a conventional cathode ray tube, and FIG. 2 is a sectional view showing a ...

Problems solved by technology

However, as described above, when the outer edge angle S of the display screen 1 is large, the reinforcing strip 11 is liable to slip.

Therefore, it is difficult to perform the reinforcing tape winding process, and it is difficult to effectively distribute the stress applied to the pipe portion 10 when the reinforcing tape 11 slips.
