A field ion display device comprises a field ion emission plate, a microchannel plate and a fluorescent display plate, said plates facing parallel to each other, having gaps therebetween, and being peripherally sealed with a rare gas filled inside. The device is addressed with X-Y encoding. When a signal is applied to an addressed point, positive field ions are emitted from the corresponding point on the emission plate based on the signal strength, pass through the microchannel holes, impinge on the wall of the holes, so that the emission of secondary electrons is multiplied. Said secondary electrons are accelerated by the accelerating electrode, converted into a strong electron flow, extracted from the other side of the holes, again accelerated by the screen electrode, and finally bombard a corresponding pixel on the screen, thereby forming an image. The image has the advantage of good quality, high efficiency and low cost. <IMAGE> |
