Abstract
A flat storage cathode ray tube with enhanced brightness is described. A mesh collector and a dielectric storage site array form an integral part of a silicon wafer. The silicon wafer includes thereon an addressable array of field effect transistors having a field effect transistor associated with a dielectric storage site in the storage site array for controlling a writing of the dielectric storage site. The addressable array of transistors works in cooperation with a flooding electron gun to effect selective writing of the storage site array. The enhanced brightness cathode ray tube may be adapted for use in a projection display.
