Claim Objections
Claims 1-16 and 18-19 are objected to for the reasons discussed below.
Claim 1: “adjacent pixel regions” (2nd to the last line) may need to be changed to “the adjacent pixel regions” since the term was previously recited. For purposes of examination, the claim language is interpreted as discussed in the rejections.
Claims 3 and 18: “the wavelength parameter conforms” should be changed to “[[the]]a wavelength parameter that conforms” since the term was not previously recited and to read better.

Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 17-19 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 17-18 recite a/the “display manufacturing method”. However, it is unclear whether the claims are directed to manufacture or a method (the two “manufacturing” limitations correspond to the former and the “acquiring”, “analyzing”, and the two “wherein” limitations correspond to the latter in claim 17, and the “turning off” limitation corresponds to the latter in claim 18). Also, claim 19 depends from rejected claims 17-18. For purposes of examination, the claim language is interpreted as discussed in the rejections.
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 of this title, 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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or non-obviousness.
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. Applicants are 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.

However, it is noted that Zheng as modified by Broeng, as particularly cited, does not teach:
the preset condition is represented as a wavelength level of the at least one lighting unit is a highest wavelength level and/or a lowest wavelength level of the multiple wavelength levels,
but which would have been obvious to include, such that Zheng as modified teaches: the preset condition is represented as a wavelength level of the at least one lighting unit is a highest wavelength level and/or a lowest wavelength level of the multiple wavelength levels, since it would have been within the general skill of one of ordinary skill in the art to select features on the basis of their suitability for the intended use to improve luminance and chromaticity uniformity by turning off at least one lighting unit that has “a small effect on the overall brightness of the display sub-region….” (Zheng: see “[0206]… [T]he turned-off sub-pixel unit may be a low grayscale sub-pixel unit…. [T]he low grayscale sub-pixel unit has a small effect on the overall brightness of the display sub-region…. The low grayscale may be the grayscale with a grayscale value less than a preset value. The preset value may be set according to the actual situation, and the preset value may also be adjusted in real time during the driving process of the display panel….”).
