ABSTRACT:
A color pixel element for field emission display includes a sealed container having a light permeable portion, at least two anodes, a cathode, at least two phosphor layers formed on the end surfaces of the anodes, and at least two CNT strings electrically connected to and in contact with the cathode with the emission portions of the CNT strings suspending. The phosphor layers are opposite to the light permeable portion, and one emission portion is corresponding to one phosphor layer. In each CNT string, some of CNT bundles are taller than and project over the adjacent CNT bundles, and each of projecting CNT bundles functions as an electron emitter. The anodes, the cathode, the phosphor layers and the CNT strings are enclosed in the sealed container. The luminance of the color pixel element is enhanced at a relatively low voltage.
