Problems solved by technology

However, the thicker the glass thickness, the higher the manufacturing cost and the bulkier the product will be
In addition, the anti-knock performance can be improved due to locally thickened glass thickness, but in this case, the difference in thickness in the glass is not good for thermal performance
Therefore, implosion may occur due to thermal properties, which can cause accidents

Abstract

Provided is a scoop part for cathode ray tubes and cathode ray tubes within the same. The scoop part includes: a sealing brim part; a main body part having a linearity range consecutive with the outside surface of the sealing brim part and declining from the bottom of the sealing brim part to the tube axis line, and a crook consecutive from the linearity range; and a yoke part extending from the crook of the main body part.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2005-0087726 filed with the Korean Intellectual Property Office on September 21, 2005, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a funnel for a cathode ray tube (CRT), and more particularly, to a funnel for a CRT that is stress-relaxed and lightweight, and a CRT having the funnel. Background technique [0004] A cathode ray tube is used in the manufacture of color televisions, computer monitors, etc., and basically includes three structural elements. Specifically, the CRT includes a panel for displaying images, a conical panel disposed in the rear of the panel, and a neck in a tubular shape attached to the apex of the bucket. The panels, bucket and neck are all made of glass. Specifically, the panels and buckets are manufactured by press-forming a mass of molten glass cal...
