摘要

Disclosed are a light-emitting element encapsulation structure, a method for fabricating the same, and a display panel, and the light-emitting element encapsulation structure includes: a first substrate; a second substrate arranged opposite to the first substrate; a light-emitting element located on the side of the second substrate facing the first substrate; an encapsulation layer made of a water-absorbent material, and filled in edge areas of the first substrate and the second substrate, wherein a hermetic space is defined by the encapsulation layer, the first substrate, and the second substrate, and the light-emitting element is located in the hermetic space; and a filler; the hermetic space is full of the filler except for an area occupied by the light-emitting element.

說明書

As illustrated in FIG. 10, a jig 7 including grooves 8 is prepared.

As illustrated in FIG. 11, the encapsulation layer 3 bonded with the first protective film 31 and the second protective film 32 is placed into the grooves 8 of the jig 7, and the second protective film 32 comes into contact with the bottoms of the grooves 8. It shall be noted that one or more light-emitting elements can be encapsulated concurrently in a particular fabrication process, although some embodiments of this disclosure will not be limited thereto.

As illustrated in FIG. 12, the first protective film 31 of the encapsulation layer is removed.

As illustrated in FIG. 13, the jig 7 carrying the encapsulation layer 3 is aligned and fit with the first substrate 1 (which can optionally be a glass package substrate).

As illustrated in FIG. 14, the jig 7 is removed, and the first substrate 1 is flipped.

As illustrated in FIG. 15, the second protective film 32 is removed.

As illustrated in FIG. 16, the transparent filler 4 is filled in the semi-hermetic area defined by the first substrate 1 and the encapsulation layer 3.

As illustrated in FIG. 17, the first substrate 1 is aligned with the second substrate 2 including the light-emitting element.
