Disclosed is a novel packaging method for organic polymer EL displays characterized by passivating the organic polymer EL display with a heat-dissipating layer by sputtering deposition. By using this heat-dissipating layer, the heat generated by the EL display can be dissipated. In addition, this passivating and heat-dissipating layer can prevent the cathode and the polymer luminant layer from reacting to the oxygen and moisture in the air, thereby the degradation of the polymer EL display can be eliminated. Moreover, a packaging shell with grids set inside or covering layer consisting of material with high thermal conductivity is formed on the top of the heat-dissipating layer to consolidate the structure of the heat-dissipating mechanism and enhance the effect of heat-dissipation.
