Abstract: A field emission display having emitters controlled by an integrated driving circuit. The field emission display includes a charge shield positioned above exposed areas of the substrate to protect driving circuitry integrated into the substrate. The charge shield is a conductive layer within an insulative layer covering the driving circuit. The charge shield is connected to ground or to a low reference potential to bleed away current within the insulative layer, thereby preventing drifting charges from affecting the electrical response of the integrated driving circuit. The charge shield also terminates electric fields within the insulative layer to reduce the effect on the integrated driving circuit of dynamic variations in surface charge. Electrical characteristics of the driving circuit thus remain constant, reducing variations in the current supplied to the emitters, thereby reducing variations in the intensity of light emitted by the display.

Abstract: An improved field emission cathode and methods for fabricating such a cathode are disclosed. In the methods of the invention, the field emission cathode is made from at least one body containing a first substance. The method steps include a preparation of irregularities in an emitting surface of the body, adding to the emitting surface of the body ions of a second substance with a low work function, and modifying the emitting surface by inducing field emission in applying a variable electric field to the body and increasing the field strength in steps.

Abstract: Strips of field emitters (30) arranged in rows overlap grid electrodes (32, 32', 32'') when viewed in the viewing direction (36) to define pixel dots. Scanning electrical voltages are applied to the rows of field emitters (30) to perform scanning and data potentials are applied to the grid electrodes (32, 32', 32'') to control the brightness of the display. Potentials applied to the grid electrodes (32, 32', 32'') also focus the electrons from the field emitters (30). A metal mesh with grid electrodes (32, 32', 32'') fabricated thereon to form an integrated structure greatly simplifies the manufacture of the display.
