Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. 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. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 1-4, 7-8, 12, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Du et al. (U.S. Patent No. 11,711,956) in view of Sharma et al. (U.S. Patent No. 12,412,835). Regarding to claim 1, Du teaches a display panel, comprising a display region and a fan-out wire region, wherein the display region comprises a plurality of data lines, the fan-out wire region comprises a plurality of fan-out wires, and a fan-out wire of the plurality of fan-out wires is electrically connected to a respective data line of the plurality of data lines (Fig. 4, column 8, lines 43-50); the plurality of fan-out wires comprise a plurality of first fan-out wires and a plurality of second fan-out wires, the display panel further comprises a substrate (Fig. 4). PNG media_image1.png 2151 1752 media_image1.png Greyscale Du is silent about cross-sectional view of the fan-out wire structure. Sharma discloses a second wire of the plurality of second wires is located on a side of a first wire of the plurality of first wires facing away from the substrate (Fig. 6, please also see the attached figure); the first wire comprises a first main portion and a first edge portion, the first edge portion is located at an edge of the first main portion, a thickness of the first edge portion is less than a thickness of the first main portion (Fig. 6, please also see the attached figure), the second wire comprises a second main portion and a second edge portion, the second edge portion is located at an edge of the second main portion, and a thickness of the second edge portion is less than a thickness of the second main portion (Fig. 6, please also see the attached figure); and in a thickness direction, at least one first main portion of first main portions of the plurality of first wires does not overlap at least one second main portion of second main portions of the plurality of second wires (Fig. 6, please also see the attached figure). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Du in view of Sharma to locate a second fan-out wire of the plurality of second fan-out wires on a side of a first fan-out wire of the plurality of first fan-out wires facing away from the substrate, to comprise in the first fan-out wire a first main portion and a first edge portion, the first edge portion is located at an edge of the first main portion, a thickness of the first edge portion is less than a thickness of the first main portion, to comprise in the second fan-out wire a second main portion and a second edge portion, the second edge portion is located at an edge of the second main portion, and a thickness of the second edge portion is less than a thickness of the second main portion, and to configure, in a thickness direction of the display panel, at least one first main portion of first main portions of the plurality of first fan-out wires not to overlap at least one second main portion of second main portions of the plurality of second fan-out wires, in order to reduce footprint for the wiring structure. PNG media_image2.png 779 1414 media_image2.png Greyscale Regarding to claim 2, Sharma discloses the first edge portion partially overlaps the second edge portion in the thickness direction of the display panel; or the first edge portion does not overlap the second edge portion in the thickness direction of the display panel; in a first direction, a minimum distance L between the first edge portion and the second edge portion satisfies that L≤0.3 μm; and the first direction is an arrangement direction of the plurality of fan-out wires (Fig. 6).
