摘要：A high-performance 46 cm flat-face CDT has been developed using pressed-shadow-mask technology. Despite the flatness of the panel's outer surface, the inner surface is slightly concave to give the mask sufficient strength against shock deformation. The pressed-mask suppresses the penetration of the terrestrial magnetic field and the mask-doming phenomena without the additional outer shield and the doming correction circuit, provides cost-effective display stable color purity. The use of the concave inner surface, which does not increase the miss-convergence and raster distortion, reduces the cost of the correction circuitry. A light-absorbing filter is coated on the inner surface of the panel to reduce the reflection of ambient light. A resistance layer with graded transmittance is coated on the outer surface to improve brightness uniformity. A U-Invar mask with its modified mask-hole cross-sectional structure is used to further increase the mask strength up to that of conventional CDTs.
