— High‐resolution bright CRT monitors with Spindt‐type field‐emitter arrays (FEA‐CRTs) as electron guns have been realized for the first time. The FEA chip consists of 868 electron sources arranged within an emitter circle 50 μm in diameter and a vertical current limiter (VECTL) which protects the FEA chips from damage caused by an arc electric discharge. The FEA‐CRT has a minimum electron beam diameter of 0.84 mm at 18 kV and 100 μA.
