Field emission device with two light-permeable sides
First Claim
1. A field emission device, comprising:
- a sealed container with a first light-permeable portion and an opposite second light-permeable portion;
a first phosphor layer formed on the first light-permeable portion;
a first light-permeable anode formed on the first phosphor layer;
a second phosphor layer formed on the second light-permeable portion;
a second light-permeable anode formed on the second phosphor layer;
a shielding barrel located within the sealed container and electrically connected to at least one cathode electrode, the shielding barrel having two opposite openings facing toward the first and the second light-permeable portions, the shielding barrel having an inner surface;
a conductive nano-material layer, the conductive nano-material layer located on at least a portion of the inner surface of the shielding barrel such that a hollow area is present in the shielding barrel with the conductive nano-material layer thereon.

Abstract
A field emission device (10) includes a sealed container (12) with a first light-permeable portion (120) and an opposite second light-permeable portion (122). A first phosphor layer (14) is formed on the first light-permeable portion. A first light-permeable anode (16) is formed on the first light-permeable portion. A second phosphor layer (18) is formed on the second light-permeable portion. A second light-permeable anode (20) is formed on the second light-permeable portion. A shielding barrel (22) is disposed within the container and electrically connected to at least one cathode electrode (25, 26). The shielding barrel has opposite open ends facing toward the first and the second light-permeable portions respectively. The shielding barrel has an inner surface, and a slurry layer (24) containing conductive nano material is formed on the inner surface of the shielding barrel.
