46cm 100 deg Super-High Deflection Sensitivity Color Display Tube

摘要

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