§102 §103
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 . DETAILED ACTION Status of the Claims Applicant’s election, without traverse, of Specie 2 (Fig. 5), claims 1-12 and 14-18 in the reply filed on December 15th, 2025 is acknowledged. Non-elected invention and species, claim 13 has been withdrawn from consideration. Claims 1-18 are pending. Action on merits of Species 2, claims 1-12 and 14-18 as follows. Priority Receipt is acknowledged of certified copies of papers submitted under 35 U.S.C. 119(a)-(d), which papers have been placed of record in the file. Information Disclosure Statement The information disclosure statements (IDSs) submitted on July, 26th, 2023; June 27th, 2024 and July 02nd, 2025 have been considered by the examiner. Drawings The drawings filed on 07/26/2023 are objected. The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the features: “a photosensitive component spaced apart from the pixel electrode” as recited in claim 18, must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant's cooperation is requested in correcting any errors of which applicant may become aware in the specification. Claim Rejections - 35 USC § 102 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. 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 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. Claims 1, 3 and 17 are rejected under 35 U.S.C. 102(a)(1) as being clearly anticipated by Yuan (CN 211238258, hereinafter as Yuan ‘258). Regarding Claim 1, Yuan ‘258 teaches a display panel, comprising: a base plate (Fig. 5, (100); [0044]); a pixel electrode layer (Fig. 5, (340); [0059]) arranged on the base plate (100) and comprising a plurality of pixel electrodes (341) distributed in an array; and a pixel definition layer (220; [0048]) located at a side of the pixel electrode layer (341) away from the base plate (100), the pixel definition layer comprising a plurality of first isolation portions (221; [0048]) distributed at intervals, each of the first isolation portions (221) being ring-shaped (see Fig. 2) and surrounding and defining a pixel opening (230; [0049]), and an edge of a first orthographic projection of the pixel electrode (341) on the base plate (100) being within a second orthographic projection of the first isolation portion (221) on the base plate (100).

Regarding Claim 17, Yuan ‘258 teaches a display apparatus (see para. [0004]). Claim Rejections - 35 USC § 103 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 2, 4-6, 15 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Yuan ‘258 as applied to claim 1 above. Regarding Claim 2, Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “a light transmittance of the first isolation portion is equal to or less than 70%.”. However, it has been held to be within the general skill of a worker in the art to select a material for the first isolation portion such that a light transmittance of the first isolation portion is equal to or less than 70% on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. A person of ordinary skills in the art is motivated to select a light transmittance of the first isolation portion is equal to or less than 70% in order to improve the performance of the display device. Regarding Claim 4, Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “the first isolation portion has a light transmittance ranging from 20% to 70%”. However, it has been held to be within the general skill of a worker in the art to select a material for the first isolation portion such that the first isolation portion has a light transmittance ranging from 20% to 70% on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. A person of ordinary skills in the art is motivated to select the first isolation portion has a light transmittance ranging from 20% to 70% in order to improve the performance of the display device. Regarding Claim 5, Yuan ‘258 teaches a plurality of light-emitting units emitting lights of different colors (310; [0050]), each of the light-emitting units (310) being located in one pixel opening (230), the second orthographic projection comprising second inner edges facing the pixel opening (230) and second outer edges away from the pixel opening, the second outer edges enclosing an isolation area and isolation areas (see Figs. 2 and 5), Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “at least two light-emitting units emitting lights of a same color are located being of different sizes”. However, it has been held to be within the general skill of a worker in the art to select at least two light-emitting units emitting lights of a same color are located being of different sizes on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 USPQ 232 (1984), the Federal Circuit held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device. PNG media_image3.png 18 19 media_image3.png Greyscale Regarding Claim 6, Yuan ‘258 teaches the first orthographic projection comprises first outer edges, for the first orthographic projection within the isolation area, a distance between the second outer edge and the first outer edge is a first distance D1 greater than 0 (see Fig. 5). Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “the first distances D1 corresponding to at least two of the pixel electrodes are different”. However, it has been held to be within the general skill of a worker in the art to select the first distances D1 corresponding to at least two of the pixel electrodes are different on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed.

However, it has been held to be within the general skill of a worker in the art to have the isolation areas where at least two light-emitting units emitting lights of a same color are located are of different shapes on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966) (The court held that the configuration of the claimed disposable plastic nursing container was a matter of choice which a person of ordinary skill in the art would have found obvious absent persuasive evidence that the particular configuration of the claimed container was significant.). PNG media_image3.png 18 19 media_image3.png Greyscale A person of ordinary skills in the art is motivated to have the isolation areas where at least two light-emitting units emitting lights of a same color are located are of different shapes in order to improve the performance of the display device. Regarding Claim 16, Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “the isolation areas where two adjacent light-emitting units emitting lights of a same color are located are of different shapes”. However, it has been held to be within the general skill of a worker in the art to have the isolation areas where two adjacent light-emitting units emitting lights of a same color are located are of different shapes on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966) (The court held that the configuration of the claimed disposable plastic nursing container was a matter of choice which a person of ordinary skill in the art would have found obvious absent persuasive evidence that the particular configuration of the claimed container was significant.).

Regarding Claim 18, Yuan ‘258 teaches a photosensitive component spaced apart from the pixel electrode (see para. [0005]). Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “a light transmittance function of the first isolation portion satisfying the following equation: wherein PNG media_image4.png 90 454 media_image4.png Greyscale wherein (x0, y0) is a coordinate of a position of the first isolation portion, F-1 represents inverse Fourier transform, ε0 is a distance from a position of an n-th first isolation portion to an axis x0, η0 is a distance from the position of the n-th first isolation portion to an axis y0, fx = x/(λ x z), fy = y/(λ x z), and z is a distance from the pixel electrode to the photosensitive component”. However, it has been held to be within the general skill of a worker in the art to have a light transmittance function of the first isolation portion satisfying the following equation: PNG media_image4.png 90 454 media_image4.png Greyscale on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. A person of ordinary skills in the art is motivated to have a light transmittance function of the first isolation portion satisfying the above equation in order to improve the performance of the display device. Claims 7-12 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Yuan ‘258 as applied to claim 5 above, and further in view of Yang (US 2020/0075698, hereinafter as Yang ‘698). Regarding Claim 7, Yuan ‘258 teaches a plurality of the light-emitting units (310; [0050]) emitting lights of different colors (e.g. red, green and blue) are combined to form a repeating unit, a plurality of repeating units are distributed in an array in the display panel (see Fig. 2). Yuan ‘258 is shown to teach all the features of the claim with the exception of explicitly the limitations: “the first distances D1 corresponding to the light-emitting units in at least two of the repeating units are different”. Yang ‘698 teaches the first distances D1 corresponding to the light-emitting units in at least two of the repeating units are different (301; [0086]) (see Fig. 12). Thus, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the invention to modify Yuan ‘258 by having the first distances D1 corresponding to the light-emitting units in at least two of the repeating units are different for the purpose of providing a display apparatus with minimum unwanted deformation (see para. [0004]) as suggested by Yang ‘698. Regarding Claim 8, Yuan ‘258 teaches the first distances D1 corresponding to the light-emitting units within the repeating units are equal (see Fig. 5). Regarding Claim 9, Yang ‘698 teaches the first distances D1 corresponding to the light-emitting units in adjacent repeating units are different (301; [0086]) (see Fig. 12). Regarding Claim 10, Yuan ‘258 and Yang ‘698 are shown to teach all the features of the claim with the exception of explicitly the limitations: “at least two light-emitting units emitting lights of a same color are located being of different sizes”. However, it has been held to be within the general skill of a worker in the art to have at least two light-emitting units emitting lights of a same color are located being of different sizes on the basis of it suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. In Gardner v. TEC Systems, Inc., 725 F.2d 1338, 220 USPQ 777 (Fed.
