Abstract
In a field emission display, a microchannel plate is mounted between an emitter panel and a display screen. The inner walls of the cylindrical passageways through the microchannel plate are coated with a conductive layer which is connected to a plate voltage. Electrons emitted from the emitter panel travel through cylindrical passageways in the microchannel plate toward the display screen. As electrons pass through the microchannels, the electrons are multiplied and collimated to increase the intensity of the light emitted from the screen and to reduce the pixel size.
