It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the plurality of aperture patterns as claimed of Park to device of Shin in order to prevent the curl phenomenon of the substrate from occurring in the unfolding region (Park and col 3, lines 15-20) Regarding claim 2, Shin/Park discloses the display device according to claim 1. Park further teaches (see annotated fig above) wherein the inner hole pattern has a width that is greater than a width of the outer hole pattern in the plurality of aperture patterns. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the widths of the inner/outer hole patterns as claimed of Park to device of Shin in order to prevent the curl phenomenon of the substrate from occurring in the unfolding region (Park and col 3, lines 15-20) Regarding claim 5, Shin/Park discloses the display device according to claim 1. Shin further teaches (figs. 1-11) wherein the bottom plate overlaps with the plurality of flat areas and is bonded to a top surface of the system middle frame via a plurality of adhesives in the folding area. Regarding claim 7, Shin/Park discloses the display device according to claim 1. Shin further teaches (figs. 1-11)wherein the plurality of aperture patterns include stripes extending in at least one direction of a first direction parallel to the folding axis, a second direction orthogonal to the first direction, and a diagonal direction between the first direction and the second direction, or connected in a matrix form (shows in fig.3). Regarding claim 9, Shin/Park discloses the display device according to claim 1. Shin further teaches (figs. 1-11) wherein the foldable display module further comprises a driving circuit associated with the display panel and on a back surface of the system middle frame (fig.5). Regarding claim 14, Shin discloses (figs. 1-11) a display device comprising: a display panel comprising a plurality of flat areas (NFA1-NFA2), and a folding area that is between the plurality of flat areas and configured to fold relative to a folding axis (FA); a bottom plate bonded to a back surface of the display panel, the bottom plate including a plurality of folding patterns (PP3) corresponding to the folding area and a plurality of aperture patterns (PP1) corresponding to the plurality of flat areas, and a system middle frame (SUP2) bonded to the bottom plate by a plurality of adhesives (AL1-AL5) disposed separately on a back surface of the bottom plate corresponding to the plurality of flat areas, the system middle frame configured to fold relative to the folding axis (fig.4). Shin does not explicitly disclose the plurality of aperture patterns comprising an outer hole pattern and an inner hole pattern having a size that is different from a size of the outer hole pattern. However, Park further teaches (figs. 1-23) the plurality of aperture patterns comprising an outer hole pattern and an inner hole pattern having a size that is different from a size of the outer hole pattern. PNG media_image1.png 317 645 media_image1.png Greyscale It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the plurality of aperture patterns as claimed of Park to device of Shin in order to prevent the curl phenomenon of the substrate from occurring in the unfolding region (Park and col 3, lines 15-20). Regarding claim 15, Shin/Park discloses the display device according to claim 14. wherein the inner hole pattern has a width that is greater than a width of the outer hole pattern. Park further teaches (see annotated fig above) wherein the inner hole pattern has a width that is greater than a width of the outer hole pattern. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the widths of the inner/outer hole patterns as claimed of Park to device of Shin in order to prevent the curl phenomenon of the substrate from occurring in the unfolding region (Park and col 3, lines 15-20) Regarding claim 17, Shin/Park discloses the display device according to claim 14. Shin further teaches wherein the plurality of aperture patterns include stripes extending in at least one direction of a first direction parallel to the folding axis, a second direction orthogonal to the first direction, and a diagonal direction between the first direction and the second direction, or connected in a matrix form (shows in fig.3). Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Shin et al in view of Park et al and further in view of Fu et al (US Pub No. 2023/0354533 A1 and Fu hereinafter) Regarding claim 18, Shin/Park discloses the display device according to claim 17. Shin further teaches (figs. 1-11) wherein the plurality of folding patterns of the bottom plate include a plurality of slits penetrating the bottom plate and extending in the first direction (fig.3), but fails to disclose wherein a spacing between the plurality of folding patterns decreases as the plurality of folding patterns approach the folding axis of the folding area from the plurality of flat areas. However, Fu teaches (figs.1-3) wherein a spacing between the plurality of folding patterns (121) decreases as the plurality of folding patterns (12) approach the folding axis of the folding area from the plurality of flat areas (11). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the widths of the inner/outer hole patterns as claimed of Park to device of Shin in order to prevent the curl phenomenon of the substrate from occurring in the unfolding region (Park and col 3, lines 15-20) Allowable Subject Matter Claims 3-4, 6, 8, 10-13, 16 and 19-22 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
