Abstract
A field emission type planar lamp with stacked structure and method for the same are proposed. The field emission type planar lamp includes an anode plate, a cathode plate and a panel. The anode plate includes a anode substrate. The cathode plate is stacked with the anode plate and includes an isolation mesh with a plurality of apertures and a cathode mesh with a plurality of through holes. The through holes are corresponding to the apertures. The panel is sealed with t he anode substrate to form a vacuum cavity to enclose the anode unit and the cathode plate. Electron beams generated by the cathode plate bombard the anode plate to illuminate. The illumination will exit from one side of the panel through passage defined by the aperture and the through, besides exit from one side of the anode substrate. Therefore, the field emission type planar lamp has two-side illumination.
