Seal for light emitting display device, method, and apparatus

A method of sealing a light emitting display device comprising:

• providing a light emitting layer, a first substrate and a second substrate, each substrate having an inner surface and an outer surface;
• depositing a frit around the perimeter of the inner surface of the first substrate;
• depositing a polymeric adhesive on the inner surface of at least one of the first or second substrate;
• joining the inner surfaces of the first substrate and the second substrate so that the light emitting layer is positioned between the first and second substrates, and so that at least a portion of the first substrate is in overlying registration with at least a portion of the second substrate;
• heating a first portion of the frit such that the first portion of the frit forms a hermetic seal between the first substrate and the second substrate and wherein a second portion of the frit is unsealed;
• and
• curing the polymer adhesive;
• wherein the heating and curing steps may be performed in any order.

• joining the inner surfaces of the first substrate and the second substrate so that at least a portion of the first substrate is in overlying registration with at least a portion of the second substrate and so that the light emitting layer is positioned between the first and second substrate, thereby creating a joined first and second substrate;
• depositing a polymeric adhesive around the perimeter of the joined first and second substrates;
• heating a first portion of the frit such that the first portion of the frit forms a hermetic seal between the first substrate and the second substrate and wherein a second portion of the frit is unsealed;
