12.1: e³‐Glass Bulb for Flat Face and Shallow CRTs

Abstract

As a result of the pursuit in strengthening shallow glass bulbs, a highly strengthened glass funnel has been developed by introduction of a new chemical tempering technology. The integrated technology based on the chemical tempering and previously mentioned innovations can achieve the competence to reduce dramatically the weight of the glass bulb for a wide deflection angle CRT by 45%.
