Office Action

§102
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 . Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. The examiner proposes: DISPLAY WITH AN ARRANGEMENT OF STORAGE CAPACITOR ELECTRODES Claim Interpretation Claim 1 recites that “the upper storage electrode of the first pixel and the upper storage electrode of the third pixel are arranged in a first direction, and the upper storage electrodes of the first pixel and the third pixel and the upper storage electrode of the second pixel are arranged in a second direction crossing the first direction.” The examiner interprets things being arranged in a direction to mean that they are laid out along that direction. So in this case, the first and third pixel upper storage electrodes are laid out in the first direction, the second pixel upper storage electrode and the first pixel upper storage electrode are laid out in the second direction, and the second pixel upper storage electrode and the third pixel upper storage electrode are laid out in the second direction, where the second direction is crossways from the first direction. Claim Rejections - 35 USC § 102 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1 and 2 are rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Harada, US 2022/0271115 A1. Claim 1: Harada discloses a first pixel (SP4), a second pixel (SP6), and a third pixel (SP5) for emitting light of different colors, each of the first to third pixels comprising: a lower storage electrode (MW), an upper storage electrode (CAW) overlapping the lower storage electrode and forming a storage capacitor (Cs) with the lower storage electrode, and a pixel electrode (E1) overlapping the upper storage electrode, and wherein the upper storage electrode of the first pixel and the upper storage electrode of the third pixel are arranged in a first direction, and the upper storage electrodes of the first pixel and the third pixel and the upper storage electrode of the second pixel are arranged in a second direction crossing the first direction. PNG media_image1.png 580 798 media_image1.png Greyscale PNG media_image2.png 790 588 media_image2.png Greyscale Claim 2: lines connecting centers of the upper storage electrodes of the first pixel, the second pixel, and the third pixel form an acute-angled triangle, and wherein a line connecting centers of the upper storage electrodes of the first pixel and the third pixel is parallel to the first direction, a line connecting centers of the upper storage electrodes of the first pixel and the second pixel forms an acute angle with respect to the first direction, and a line connecting centers of the upper storage electrodes of the second pixel and the third pixel forms an obtuse angle with respect to the first direction. PNG media_image3.png 420 588 media_image3.png Greyscale As the capacitors surround each pixel, the center of each electrode is the center of the pixel. Claim 11 is rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Jo, US 2021/0287606 A1. Claim 11: Jo discloses a light emitting display device comprising a unit pixel comprising a first pixel (OLED1), a second pixel (OLED3), and a third pixel (OLED2) for emitting light of different colors, the unit pixel further comprising: a substrate (10); lower storage electrodes (CE2b) of the first, second, and third pixels on the substrate; a first insulating layer (IL1 and/or IL2) on the lower storage electrodes; upper storage electrodes (CE1) of the first, second, and third pixels on the first insulating layer; a third insulating layer (IL3) on the upper storage electrodes; a fourth insulating layer (IL4) on the third insulating layer; pixel electrodes (211) of the first, second, third pixels on the fourth insulating layer and overlapping the upper storage electrodes (FIG. 5); and a fifth insulating layer (PDL) having openings overlapping the pixel electrodes, wherein the upper storage electrode of the first pixel overlaps the upper storage electrode of the third pixel in a first direction, and the upper storage electrodes of the first and third pixels overlap the upper storage electrode of the second pixel in a second direction crossing the first direction. PNG media_image4.png 632 422 media_image4.png Greyscale Allowable Subject Matter Claims 3-10 and 12-20 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. The examiner did not find the claimed invention with the three capacitor electrodes arranged and connected as claimed with the data lines, the driving voltage line and auxiliary driving voltage line, the common voltage line, and the auxiliary common voltage line. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Park, US 2023/0180554 A1, Kim, US 2020/0212154 A1, and Liu, CN 114709247 A, which show potentially relevant capacitor electrode arrangements.
