48.1: Distinguished Contributed Paper: Development of a 32‐in. Wide‐Deflection‐Angle CRT(125 deg)

We developed a 32inch wide-deflection-angle CRT of 125 degree (Tube length 360mm) and started mass production from this January. Wide deflection requires much advanced design of major parts and facilities in production line. In this paper, we will mainly introduce new designs for DYs and Electron Guns considered to be the most difficult. These wide deflection CRTs attracted extraordinary strong supports from even end users in a variety of display shows last year. We expect they would maintain the solid position of CRTs in the coming era of display device competition.
