Abstract
A method for affixing spacers (126, 226, 326) in a field emission display (100, 200, 300) includes the steps of: (i) providing a first display plate; providing a plurality of spacers (126, 226, 326) having first (128, 228, 328) and second opposed edges (130, 230, 330), (ii) coating first opposed edge (128, 228, 338) with a bonding layer (132, 232, 332), (iii) forming a metallic bonding pad (134, 234) on an inner surface (106, 206, 306) of first display plate, and (iv) applying a energy beam (136, 236, 336) to the bonding layer (132, 232, 332) and metallic bonding pad (134, 234), thereby forming a metallic bond.
