Development of a 32-in. slim CRT with 125° deflection

— Today, CRT markets are being threatened by flat‐panel displays (FPDs) even though the screen quality of the CRT is one of the best of existing display devices. The depth of CRTs is one of its most important design factors to maintain its dominant position in the display market. Thus, a 32‐in.‐wide deflection‐angle 125° CRT (tube length of 360 mm) has been developed, and mass production began in January 2005. Wide deflection requires more advanced design of the major parts and reliable facilities in the production line. In this paper, new designs, mainly for deflection yokes and electron guns, will be introduced, which are considered the most difficult to design. These wide‐deflection CRTs attracted an extraordinary amount of attention even from end users in a variety of display shows last year and will help maintain the solid positions of CRTs in the coming era.
