Cathode ray tube comprising a semiconductor cathode |
| abstract |
Cathode ray tube comprising an electron gun which is constructed in such a way that the gas pressure near the electron-emissive layer (30) of the cathode is lower than in the other parts of the tube. This can be achieved by reducing the aperture between the G1 (33) and G2 (36), by providing the G2 (36) with a skirt (43). The wall of the skirt, the G1 and the G2 may also be at least partly coated with a getter (41). |
