Description of the Invention (彳) This application was filed in the United States with patent application number 09 / 614,367 on July 12, 2000. Scope of the invention The present invention belongs to the field of field emission display and more particularly to a field emission display with a dielectric spacer, and the spacer of the field emitter maintains the isolation between a cathode plate and an anode plate of the field emission display. Distance. BACKGROUND OF THE INVENTION A field emission display having a dielectric spacer for maintaining a separated distance between a cathode plate and an anode plate of a display is a known technique. It is also known that the isolation surface of the dielectric spacer of the technology can become electrostatic charging when the display is operated. The electrostatically charged surface of the dielectric separator causes problems such as " visibility " for viewers with the separator structure presenting a display. That is, the charged surface causes electrons directly facing the phosphorescent substance to be attracted to the charged surface and away from the scaled substance. In this case, an unnecessary gap is formed at each spacer position of the display image. When operating on a display, the surface of the charged separator is always neutralized to a known technique. For example, it is known in the art to use an electron emitter to excite a phosphorescent substance to provide a surface for discharging the charged separator to discharge the electrons. Previous techniques have shown that electron discharge is often provided when the voltage on the phosphorescent material is reduced to a display mode. Display mode 値 is used for active phosphorescent substances. Although such discharged electrons are useful for discharging the surface of the separator, some electrons may be attracted to the surface of the non-isolator. Can cause pollution when the electrons of the orbit hit the surface of the non-isolator. -4- This paper size applies to China National Standard (CNS) A4 (210X297 mm) A7

Figure ^ is a partial cross-sectional view of a field emission display (FED) 400, one of the field emission display (FED) 400, which is a field emission display (FED) 400 when the emitter 1 16 is caused to emit when it is caused to emit. The cathode plate 402 has a further definition, a description of the invention (^ the dielectric layer 412 of the electric emitter well 4U. A discharge electron emitter 409 is arranged in the discharge emitter well 411. ^ The specific embodiment of FIG. 3 is the same, The cathode plate cut 2 has a discharge gate defined by the :: gate lead-out electrode 418.

The gate lead-out electrode 41 8 is separated from the discharge electron emitter 4 09 to be able to be configured. Discharge from the discharge electron emitter 4 0 9 The same as in the specific embodiment of FIG. 3, FED4OO defines a traction for the isolator: the structure of the bun 134 <diode structure. The triode is made of a discharge electrode 4 9 9 and a gate. The extraction electrode 418 and the anode 125 are defined. The difference from the conventional embodiment in FIG. 3 is that the discharge electron emitter is connected to the first voltage power source through the cathode 110, and the discharge electron emitter 4 09 is designed. Chenglai provides a separator-discharge electricity to 134 to discharge the charged first surface 105 to a sufficient discharge ratio. For example, 'discharge electron emitter 409 can be charged by an electron emitting material: <electron Emitter 1 16 is made of materials.
