| 摘要 |
A method of forming a planar emissive device, such as a flat fluorescent lamp or plasma display panel, including the steps of applying a frit paste including spherical spacers onto a broad face of a first planar substrate; setting the frit paste; coupling a second planar substrate to the frit paste; and flowing the frit paste to form a seal between the first and second substrate, wherein the gap size between the first and second substrate is substantially defined by the spacer diameter.
