ABSTRACT:
A flat television screen, comprising several electron-emitting devices, each essentially consisting of an electric power supply connected to two plates of a capacitor supplying by one of these plates at least one field emission and an extraction grid placed close to the top of the field emission, the grid itself being connected to the other plate of the capacitor by a variable voltage generating device, these devices being connected together facing a fluorescent screen placed to receive a flow of electrons emitted by the field emission of each of the devices.
