三菱电机公司开发出一种显像管用的阴极,其电流密度为3A/cm~2,为过去显像管阴极的1.5倍。电流密度大可提高显像管的分解力。例如,使用新开发阴极的显像管的电视机显示文字数目约为过去的两倍。不过,这种阴极的生产成本提高了1.1倍。该公司开发这种阴极的目的在于将使用这种阴极的显像管用在因特网(Internet)电视机里。
Mitsubishi Electric has developed a CRT cathode, the current density of 3A / cm ~ 2, cathode of the past CRT 1.5 times. High current density can improve the tube decomposition. For example, TVs using newly developed tubes have about twice as many teletexts. However, this cathode production costs increased 1.1 times. The company developed the cathode for the purpose of using a cathode ray tube in an Internet TV.
