46cm 100°super-high deflection sensitivity color display tube

摘要

We have developed a 46cm wide-deflection 100° super-high deflection sensitivity color display tube (S-HS CDT), which is shorter than the conventional 41 cm 90° CDT. To reduce deflection power, we adopted a mini-neck (22.5 mm dia.) and rectangular cone (RAC) system. Despite the wide angle of deflection, the horizontal deflection sensitivity of the CDT is higher than that of the conventional 41 cm 90° CDT, while the resolution is as same as the conventional 46 cm 90° CDT. Moreover, the temperature rise of the deflection yoke is low enough for high-frequency scanning operation under 110kHz.
