日本最近使用一种含有电子注引示系统的彩色显象管,研制成6英寸彩色电视机样机.该机耗电仅12瓦,使用干电池电源可工作约三小时.电子注引示系统通过一只单电子枪激发出三原色荧光,从而可以去掉显象管内遮断电子注80%的阴罩,这就大大减少了电视机功耗,使电子注效率提高 Japan recently developed a 6-inch color television prototype using a color picture tube with an electronic charge-indicating system that consumes only 12 watts of power and operates on dry-battery power for about three hours. The electronic note- Only single electron gun excitation of the three primary colors of fluorescence, which can be removed within the kinescope cut off 80% of electronic shadow mask, which greatly reduces the TV power consumption, the electronic injection efficiency
