日本某公司最近制成20英寸超高分辨力黑白显象管.这种管子的问世,给研制大口径透镜电子枪和采用低压、宽频带电路设计带来可能性. 此种超高分辨力显象管的显示容量是目前一般最佳显象管的两倍,每行能显示200个英文字母和数字;整个屏幕能显示22,000个字符.它能显示平滑曲线的图象,它由2,000×2,000个象素组成. A Japanese company recently made 20-inch ultra-high resolution black and white picture tube.The advent of this tube to the development of large-aperture lens electron gun and the use of low-voltage, wideband circuit design possibilities.This ultra-high resolution imaging The tubes display twice as much as the best kinescopes currently available, with 200 alphanumeric characters per line and 22,000 characters for the entire screen. It displays a smooth curve of 2,000 x 2,000 Pixel composition.
