Abstract:
1. A process of packaging an organic electroluminescent panel, the electroluminescent panel comprising a transparent substrate, a plurality of anodes formed on the transparent substrate, wherein each of the anodes has a driving area and at least one connecting area laterally connected to the driving area, a patterned organic electroluminescent layer formed on the transparent substrate or on the anodes, wherein the patterned organic electroluminescent layer exposes the connecting area, a plurality of cathodes formed on the organic electroluminescent layer, wherein at least a portion of cathodes exposes the connecting area, a protective layer having a plurality of first openings formed on the transparent substrate, wherein the first openings expose the connecting area and a portion of the cathodes, and a plurality of polysolder interconnections formed on exposed connecting area and the portion of the cathode for forming a polysolder interconnection array, the process comprising: providing a printed circuit board having a plurality of bonding pads; forming a plurality of bumps on the bonding pads; forming a filler on the printed circuit board; disposing at least one organic electroluminescent panel on the printed circuit board; performing a reflow process for electrically connecting the polysolder interconnections with the bumps; and crosslinking the filler.
