日本佳能公司开发了一种薄型显示新技术,可以使画面亮度与阴极射线管的一样。一般阴极射线管在支取电子时,要加热阴极,使热电子逸出,而本公司试制的冷阴极则是利用隧道效应,使电子由金电极,通过薄绝缘层跑到铝电极一端,隧道电子再通过铝电极跑入真空,碰撞荧光屏而发光。该冷阴 Japan’s Canon has developed a thin display of new technologies, you can make the screen brightness and cathode ray tube the same. General cathode ray tube in the extraction of electrons, to heat the cathode, so that hot electrons escape, and our trial of the cold cathode is the use of tunneling effect, the electron from the gold electrode, through the thin insulation layer ran to one end of the aluminum electrode, Tunnel Electronics Then run through the aluminum electrode vacuum, collision screen and light. The cold shade
