  • Patent number: 5628662
    Abstract: An anode plate 40, suitable for use in a field emission display tetrode, includes a transparent planar substrate 42 having thereon a layer 46 of a transparent, electrically conductive material, which comprises the anode electrode of the display tetrode. Barrier structures 48 comprising an electrically insulating, preferably opaque material, are formed on anode electrode 46 as a series of parallel ridges. Atop each barrier structure 48 are a series of electrically conductive stripes 50, which function as deflection electrodes. Luminescent material 52 overlies anode electrode 46 in the channels between barrier structures 48. Conductive stripes 50 are termed into three series such that every third stripe 50 is electrically interconnected. Deflection voltage controller 70 permits selective deflection of electrons toward the proper luminescent material 52.
