Claim 13:
14. A manufacturing method for a stretchable display module, wherein the manufacturing method comprises steps of:
S101, providing a rigid base and forming a flexible substrate on the rigid base;
S102, forming a plurality of array driving islands on the flexible substrate, and forming a connecting wire electrically connected between adjacent ones of the array driving islands, wherein the array driving islands are arranged in an array and spaced apart from each other;
S103, correspondently forming a plurality of display device islands on the array driving islands;
S104, correspondently forming a plurality of encapsulation islands on the display device islands;
S105, forming a protective layer on the encapsulation islands;
S106, stripping the rigid base;
S107, patterning the flexible substrate, removing the flexible substrate corresponding to a spacing region of the array driving islands, and forming a plurality of flexible substrate islands corresponding to the array driving islands, thereby forming a plurality of display islands arranged in an array and spaced apart from each other, wherein each of the display islands comprises the flexible substrate islands, the array driving islands, the display device islands, and the encapsulation islands stacked in sequence;
S108, providing a first stretchable layer, forming a first adhesive layer on the first stretchable layer, and attaching the first adhesive layer onto a surface of the flexible substrate islands away from the array driving islands;
S109, stripping the protective layer;
S110, forming a filling adhesive layer in a spacing region of the display islands, and forming a second adhesive layer on a surface of the encapsulation islands away from the display device islands; and
S111, providing a second stretchable layer and attaching the second stretchable layer onto the second adhesive layer;
wherein the stretchable display module is partitioned into:
a stretchable region comprising a display region and a gate driving circuit region disposed outside the display region, wherein the display island are disposed in the display region, the gate driving circuit region comprises a plurality of gate driving circuit islands spaced apart from each other, and adjacent two of the gate driving circuit islands are electrically connected by the connecting wire, and the adjacent gate driving circuit islands are electrically connected to the display islands by the connecting wire; and
a non-stretchable region connected to a side of the stretchable region, wherein the non-stretchable region comprises a bezel wire and a binding region.
