Abstract:
1. An organic light-emitting diode package structure, comprising: a substrate comprising an organic light-emitting element; a cover plate comprising an annular groove along a periphery of the cover plate, wherein the annular groove surrounds the organic light-emitting element; and a packaging adhesive having a thickness greater than a depth of the groove, wherein a portion of the packaging adhesive is located inside the groove of the cover plate, a portion of the packaging adhesive extends outside the groove of the cover plate, and the cover plate and the substrate are adhered to each other by the packaging adhesive, so as to seal the organic light-emitting element, wherein a spacer is provided between the organic light-emitting element and the cover plate such that the spacer contacts a surface of the organic light-emitting element and contacts a surface of the cover plate, and wherein a thickness of the spacer is less than about 2 μm, and wherein the adhesive extends both into the organic light-emitting element beyond the surface of the organic light-emitting element and into the cover plate beyond the surface of the cover plate.
