Cyclotron displays

摘要

The present invention comprises cyclotron display devices similar to cathode ray tubes (CRTs) in which the CRT electron gun is replaced by one or more cyclotrons that produce electrons using lower voltages and energy costs than a CRT electron gun does. This can be done both with monochrome and color displays, as disclosed. In addition, the electrons emerge from the cyclotron with adequate velocity, thus obviating the need for accelerating electrodes. The need for electron focusing is also greatly reduced, or eliminated, since the electrons emerge from the cyclotrons as beams, rather than as diffuse clouds. The cyclotron display assembly can be made to be significantly shorter than the conventional electron gun CRT. In addition, an array of cyclotrons, rather than just a single one, can be used, so that each cyclotron maps to a fractional portion of the video screen. This further shortens the length of the cyclotron display. <IMAGE>
