Abstract
An electron beam injection structure for flat panel display device includes electron injection electrodes which span a beam guide assembly for propagating electron beams. One end of the electron injection electrodes is in closer proximity to the cathode than the corresponding end of the beam guide structure. The injection of electrons from the cathode to the beam guide structure therefore can be maximized by increasing the voltage on the electron injection electrodes while permitting changes in the operating voltages applied to the beam guide structure and other elements of the display device.
