ABSTRACT:
An LCD projection system, located within a standard color CRT, is used to oject toward the screen decay stimulation patterns that vary dynamically from one frame to the next for each pixel based on the video signals received from external sources. This controls the output light intensity of the phosphors that are excited by a single electron gun. This system eliminates the three-electron-gun configuration of the standard CRT as well as the requirement of a shadow mask. What results is a CRT that is more rugged, easier to manufacture and that produces brighter and sharper images on its screen.
