an optical adhesive film structure having an alignment function, the optical adhesive film structure comprising:
an optical adhesive layer; and
a release film, disposed on the optical adhesive layer, wherein a first film surface of the release film facing away from the optical adhesive layer has a plurality of marks, and the marks are recessed into the release film relative to the first film surface and do not run through the release film; and
a plurality of display panels, disposed on the optical adhesive layer;
wherein the marks are disposed in a form of a two-dimensional array, and the display panels are disposed in a form of a corresponding two-dimensional array;
wherein the optical adhesive layer is disposed between the display panels and the release film, and the display panels are disposed respectively to correspond to the marks.
2. The stitching display module according to claim 1 , wherein each of the display panels comprises a circuit substrate and a plurality of light emitting components, and the light emitting components are disposed between the circuit substrate and the optical adhesive layer.
3. The stitching display module according to claim 2 , wherein each of the display panels further comprises an encapsulating adhesive layer disposed to cover the light emitting components, and the encapsulating adhesive layer is disposed between the light emitting components and the optical adhesive layer.
4. The stitching display module according to claim 1 , wherein a light emitting surface of each of the display panels and a second film surface of the optical adhesive layer facing away from the release film are coplanar.
