Abstract
A field emission display (100, 200, 300) and a method of making the same are disclosed. The field emission display (100, 200, 300) includes an anode (110, 210, 310) having a plurality of cathodoluminescent deposits (120, 220, 320), a back plate (185, 285, 385) including a cathode (130, 230, 330) having a plurality of field emitters (140, 240, 340) and being affixed to a cathode reinforcement member (170, 270, 370), and a plurality of side members (150, 250, 350) disposed between the anode (110, 210, 310) and the cathode (130, 230,330) and hermetically affixed thereto. The thicknesses of the anode (110, 210, 310) and the back plate (185, 285, 385) are sufficient to provide the structural support necessary to maintain the mechanical integrity of the field emission display (100, 200, 300).
