Abstract: An electron emitter for a display provides an electron source, an electron accelerator, an electron collector disposed between the electron source and the electron accelerator, and one or more electron deflectors to selectively deflect electrons in an electron beam or electron plane towards the electron collector phosphorous coating on a display screen, within a non-metallic vacuum chamber having an adjustable vacuum. Pinhead electrode electron deflectors may each control one color of a pixel, and each set of three adjacent pinhead electrodes may comprise a complete pixel on the display screen.

Abstract: An electron emitter provides a photocell having at least one photosensitive side, an electron accelerator, an electron collector disposed between the photosensitive side of the photocell and the electron accelerator, a non-metallic vacuum chamber having an adjustable vacuum containing the photocell, the electron accelerator and the electron collector; and a light source to excite electrons on the photosensitive side of the photocell. Upon light activation, infrared light strikes the photocell, causing electrons to be excited and released. The highly positively charged electron accelerator will attract the electrons under sufficient vacuum conditions. Some of the electrons travelling towards the electron accelerator will encounter the electron collector and be collected thereon. The device may be used as a rectifier or regulator to replace vacuum tubes such as for audio amplifiers and high voltage devices. It may also have application as an x-ray generator, an electron microscope or a display screen.
