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.
