Forming a grid structure for a field emission device
A conducting mesh grid electrode for a triode structure in a field emission display is formed using a stitching or bonding process. The raw material for the grid electrode may be fed continuously from a spool. The process provides for multiple bonding of wire grid conductors to form a cathode grid. The properties of the cathode and the electron beam may be modulated by varying process parameters and material dimensions.
