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

The step S902 is to fill a transparent filler in a semi-hermetic area defined by the first substrate and the encapsulation layer.

The step S903 is to align and fit the first substrate with a second substrate including a light-emitting element.

Optionally, aligning and fitting the first substrate with the second substrate including the light-emitting element includes:

    • removing the second protective film; and
    • aligning and fitting the first substrate bonded with the encapsulation layer and filled with the transparent filler, with the second substrate.

Optionally, after the first substrate is aligned and fit with the second substrate including the light-emitting element, the method further includes:

    • thermally pressing and fitting, and thermally curing the encapsulation layer between the first substrate and the second substrate aligned and fit with each other.

In order to make the method for fabricating a light-emitting element encapsulation structure according to some embodiments of this disclosure more apparent, the method for fabricating a light-emitting element encapsulation structure according to some embodiments of this disclosure will be described below in details with reference to FIG. 10 to FIG. 17, where a plurality of light-emitting elements are encapsulated concurrently using a jig according to some embodiments of this disclosure.
