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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 08/14/2026 has been entered.
Response to Arguments
Applicant's arguments filed 08/14/2026 have been fully considered but they are not persuasive. In particular, the applicant argues that cited prior arts fail to teach “a plurality of first anode reset lines disposed respectively in each of (2k)th pixel rows (k being a natural number) excluding (2k-1) pixel row; and a plurality of second anode reset lines disposed respectively in each of the (2k-1)th pixel row excluding the (2k)th pixel rows”. The Office respectfully submits that Li (US Pub. 2024/0021149 A1) discloses a display panel comprising a plurality of first anode reset lines Ref2_1 are connected together to form a first grid; and a plurality of second anode reset lines Ref2_2 are connected together to form a second grid. Therefore, a plurality of first anode reset lines Ref2_1 in even-numbered pixel rows (i.e., (2k)th first anode reset lines Ref2_1) are equivalent to “a plurality of first anode reset lines disposed respectively in each of (2k)th pixel rows (k being a natural number) excluding (2k-1) pixel row” as claimed. It is noted that the plurality of first anode reset lines Ref2_1 in even-numbered pixel rows do not include a plurality of first anode reset lines Ref2_1 in odd-numbered pixel rows. In addition, a plurality of second anode reset lines Ref2_2 in odd-numbered pixel rows (i.e., (2k-1)th second anode reset lines Ref2_2) are equivalent to “a plurality of second anode reset lines disposed respectively in each of the (2k-1)th pixel row excluding the (2k)th pixel rows” as claimed. It is noted that the plurality of second anode reset lines Ref2_2 in odd-numbered pixel rows do not include a plurality of second anode reset lines Ref2_2 in even-numbered pixel rows. Therefore, a combination of Lin et al. (US Pub. 2022/0180812 A1) and Li (US Pub. 2024/0021149 A1) still teach all limitations recited in claims 1, 18, and 20.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 7-11, 16, 18, and 20-21 are rejected under 35 U.S.C. 103 as being unpatentable over Lin et al. (US Pub. 2022/0180812 A1) in view of Li (US Pub. 2024/0021149 A1).

Initialization voltages applied to red and blue pixels are different from an initialization voltage applied to a green pixel.
