长期以来,阴极射线管一直在显示技术领域占据着统治地位。阴极射线管技术成熟,成本低廉,制造容易,其高质量的色彩使其在各种信息转换器中独占鳌头。大量研究与开发经费也正继续投入阴极射线管,以减少其功耗和改变其外形(向平面显示器发展)。然而,阴极射线管显示器体积较大,又需要高电压,这与当今电子设备朝着紧凑型和便携式发展大相径 Cathode ray tubes have long dominated display technology. Cathode ray tube technology is mature, low cost, easy to manufacture, its high-quality color makes it the champion in a variety of information converters. A large number of research and development funds are also continuing to be put into cathode ray tubes to reduce their power consumption and change their appearance (toward flat panel displays). However, cathode ray tube displays are bulky and require high voltage, which is quite different from today’s electronic devices toward compactness and portable development
