Regarding Claim 22, Lee discloses (Fig. 1 to Fig. 2b) wherein the first electrode (135a) and the second electrode (135b) are electrically connected to the plurality of light emitting elements through the plurality of via holes disposed in the plurality of planarization layers (125). Regarding Claim 23, Lee discloses (Fig. 1 to Fig. 2b) wherein each of the plurality of display modules further comprises, a plurality of connection members (129) disposed in the plurality of via holes.

Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Claim(s) 2,3, is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 11664355) in view of Won, Jooyeon (US 10892312) Regarding Claim 2, Lee discloses everything as disclosed above. Lee does not disclose a plurality of first flexible films disposed on one side of the support substrate and electrically connected to one side of the plurality of link lines, respectively; and a plurality of second flexible films disposed on another side of the support substrate and electrically connected to another side of the plurality of link lines, respectively. Won, Jooyeon discloses a plurality of first flexible films disposed on one side of the support substrate and electrically connected to one side of the plurality of link lines, respectively; and a plurality of second flexible films disposed on another side of the support substrate and electrically connected to another side of the plurality of link lines, respectively. (ABSTRACT) Won, Jooyeon doesn’t exactly use the phrase “first flexible film” and “second flexible film” it teaches the same functional structure: multiple flexible films or film pad regions electrically connecting both sides of the wiring (e.g. link lines leading to panel connection and external circuit). It would have been obvious to one of ordinary skill in the art to modify Lee to include Won, Jooyeon’s flexible films motivated by the desire to reduce stress, improve reliability and facilitate routing where rigid bords are impractical. Regarding Claim 3, In addition to Lee and Won, Jooyeon, Lee discloses wherein each of the plurality of link lines (data line/scan lines) is electrically connected to one of the plurality of first flexible films (taught by Won, Jooyeon) at one side thereof, and one of the plurality of second flexible films at another side thereof. Claim(s) 10,12, is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 11664355) in view of Namkung (US 10186688) Regarding Claim 10, Lee discloses everything as disclosed above. Lee does not disclose comprising an end protection member covering the end portions of the plurality of link lines and the end portion of the support substrate. Namkung an end protection member covering the end portions of the plurality of link lines and the end portion of the support substrate (“..an anti-reflective layer…may extend to contact an end portion of the passivation layer..so that the first lateral surface contacting the passivation layer is larger than..”) describes edge/terminal protection structures near panel ends.(Column 8, lines 17-27) It would have been obvious to one of ordinary skill in the art to modify Lee to include Namkung’s end protection member covering the end portions of the plurality of link lines and the end portion of the support substrate motivated by the desire to protect against damages. Regarding Claim 12, In addition to Lee and Namking, Lee discloses wherein the plurality of anti-corrosion patterns (insulating layer) are formed of indium tin oxide. Claim(s) 13, is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 11664355) in view of Kodama et al (US 20050099666) Regarding Claim 13, Lee discloses everything as disclosed above. Lee does not disclose a filling member disposed between the support substrate and the plurality of display modules, wherein a refractive index of the filling member is identical to a refractive index of the support substrate. Kodama et al discloses filling member disposed between the support substrate and the plurality of display modules, wherein a refractive index of the filling member is identical to a refractive index of the support substrate.(ABSTRACT) It would have been obvious to one of ordinary skill in the art to modify Lee to include Kodama et al’s filling member disposed between the support substrate and the plurality of display modules, wherein a refractive index of the filling member is identical to a refractive index of the support substrate motivated by the desire to reduce reflection and improve optical performance.
