To clarify, for the same color, the weight of color for both is analyzed and classified into a particular data range )

Claim Rejections - 35 USC § 103
5. 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.
6. The factual inquiries 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 nonobviousness.
7. Claims 4, 19 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Hu et al.
( US 2022/0293053 A1 ), as applied to Claims 1, 15 and 16, further in view of Wu et al. ( US 2024/0185479 A1 ).
As per Claim 4:
Hu does not explicitly teach “when the target pixel does not have a matched target adjacent pixel, obtaining a preset reference binding gray value; and determining the area compensation parameter corresponding to the target pixel according to a gray difference between the first binding gray value and the reference binding gray value.”
However, in the same field of endeavor, target pixel compensation, Wu teaches of receiving and analyzing pixel information of a target pixel, ( Wu, [0014] ), similar to Hu. Specifically, Hu teaches of determining if there is a color match and in general (or if not matching), Wu teaches of a reference value on the first characteristic parameter of the target pixel and a difference between a current value and the reference value is determined, as detailed in [0014]. In general, as combined with Hu, a reference value is incorporated and this can serve as the baseline for the differences/thresholds to be applied to, with regards to determining the data range and the display mode.
Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the reference value, as taught by Wu, with the motivation that by using the reference, notably accurate reference data, effective correction of colors can be achieved, ( Wu, [0069] ).
As per Claim 19:
Hu does not explicitly teach “when the target pixel does not have a matched target adjacent pixel, obtaining a preset reference binding gray value; and determining the area compensation parameter corresponding to the target pixel according to a gray difference between the first binding gray value and the reference binding gray value.”
However, in the same field of endeavor, target pixel compensation, Wu teaches of receiving and analyzing pixel information of a target pixel, ( Wu, [0014] ), similar to Hu.

Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the reference value, as taught by Wu, with the motivation that by using the reference, notably accurate reference data, effective correction of colors can be achieved, ( Wu, [0069] ).
As per Claim 25:
Hu does not explicitly teach “when the target pixel does not have a matched target adjacent pixel, obtaining a preset reference binding gray value; and determining the area compensation parameter corresponding to the target pixel according to a gray difference between the first binding gray value and the reference binding gray value.”
However, in the same field of endeavor, target pixel compensation, Wu teaches of receiving and analyzing pixel information of a target pixel, ( Wu, [0014] ), similar to Hu.

Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the reference value, as taught by Wu, with the motivation that by using the reference, notably accurate reference data, effective correction of colors can be achieved, ( Wu, [0069] ).
8. Claims 6, 7, 21, 22 and 27 are rejected under 35 U.S.C. 103 as being unpatentable over Hu et al. ( US 2022/0293053 A1 ), as applied to Claims 1, 15 and 16, further in view of Shan ( US 2021/0201841 A1 ).
As per Claim 6:
Hu does not explicitly teach of “obtaining a preset weight corresponding to the target pixel; and compensating a gray value of the target pixel according to the preset weight.”
However, in the same field of endeavor, compensating target pixels, Shan teaches of displays with different resolutions, ( Shan, [0050] ). Notably, Shan teaches of compensation pixels are correspondingly set with same or different preset weights. Applicant’s own specification at [0079] discloses a similar concept of setting the weights based on the resolution. Again, Hu teaches of determining/analyzing color weights and preset weights based on resolution can be implemented.
Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the preset weights, as taught by Shan, with the motivation that compensation factors can be set, or enhanced by the consideration of resolution, ( Shan, [0066] ).
Hu and Shan teach in Claim 7:
The voltage compensation method of claim 6, wherein the step of compensating the gray value of the target pixel according to the preset weight comprises:
determining a second binding gray value of the target pixel, wherein the second binding gray value represents the preset reference binding gray value or an adjacent binding gray value of a matched target adjacent pixel; comparing the first binding gray value with the second binding gray value ( Hu teaches in Figure 1, [0060] of analyzing a sub-pixel around the target sub-pixel and comparing brightness levels, i.e. gray values between the target and adjacent sub-pixels. Please note the combination with Shan with regards to the reference binding gray value based on the preset weight );
when the first binding gray value is greater than the second binding gray value, obtaining a corresponding first preset weight and compensating the gray value of the target pixel accordingly; wherein the first preset weight is a positive number; and when the first binding gray value is less than the second binding gray value, obtaining a corresponding second preset weight and compensating the gray value of the target pixel accordingly, where the second preset weight is a negative number. ( Shan, [0044] discloses comparing the voltage data of each compensation pixel to the initial driving data. Hu, [0073], and as detailed above, teaches of data ranges with greater than, less than, etc, determinations. Essentially, the concept of the preset weights is incorporated. As for it being a negative number, one of ordinary skill realizes a wide range of values can be applied to accurately classify the sub-pixel )
As per Claim 21:
Hu does not explicitly teach of “obtaining a preset weight corresponding to the target pixel; and compensating a gray value of the target pixel according to the preset weight.”
However, in the same field of endeavor, compensating target pixels, Shan teaches of displays with different resolutions, ( Shan, [0050] ). Notably, Shan teaches of compensation pixels are correspondingly set with same or different preset weights. Applicant’s own specification at [0079] discloses a similar concept of setting the weights based on the resolution. Again, Hu teaches of determining/analyzing color weights and preset weights based on resolution can be implemented.
Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the preset weights, as taught by Shan, with the motivation that compensation factors can be set, or enhanced by the consideration of resolution, ( Shan, [0066] ).
Hu and Shan teach in Claim 22:
The non-transitory computer readable storage medium of claim 21, wherein an operation of compensating the gray value of the target pixel according to the preset weight comprises:
determining a second binding gray value of the target pixel, wherein the second binding gray value represents the preset reference binding gray value or an adjacent binding gray value of a matched target adjacent pixel; comparing the first binding gray value with the second binding gray value ( Hu teaches in Figure 1, [0060] of analyzing a sub-pixel around the target sub-pixel and comparing brightness levels, i.e. gray values between the target and adjacent sub-pixels. Please note the combination with Shan with regards to the reference binding gray value based on the preset weight );
when the first binding gray value is greater than the second binding gray value, obtaining a corresponding first preset weight and compensating the gray value of the target pixel accordingly; wherein the first preset weight is a positive number; and when the first binding gray value is less than the second binding gray value, obtaining a corresponding second preset weight and compensating the gray value of the target pixel accordingly, where the second preset weight is a negative number. ( Shan, [0044] discloses comparing the voltage data of each compensation pixel to the initial driving data. Hu, [0073], and as detailed above, teaches of data ranges with greater than, less than, etc, determinations. Essentially, the concept of the preset weights is incorporated. As for it being a negative number, one of ordinary skill realizes a wide range of values can be applied to accurately classify the sub-pixel )
As per Claim 27:
Hu does not explicitly teach of “obtaining a preset weight corresponding to the target pixel; and compensating a gray value of the target pixel according to the preset weight.”
However, in the same field of endeavor, compensating target pixels, Shan teaches of displays with different resolutions, ( Shan, [0050] ). Notably, Shan teaches of compensation pixels are correspondingly set with same or different preset weights. Applicant’s own specification at [0079] discloses a similar concept of setting the weights based on the resolution. Again, Hu teaches of determining/analyzing color weights and preset weights based on resolution can be implemented.
Therefore, it would have been obvious to one of ordinary skill in the art, at the effective filed date of the invention, to implement the preset weights, as taught by Shan, with the motivation that compensation factors can be set, or enhanced by the consideration of resolution, ( Shan, [0066] ).
Response to Arguments
9. Applicant’s arguments considered, but are respectfully not persuasive.
Please note the updated rejection in light of the claim amendments. Hu teaches of various display modes which result in different brightness modes. Depending, or based on these modes, the target sub-pixel and the surrounding pixels are adjusted. Figure 4, [0068] discloses the target sub-pixel is centered and the number of sub-pixels which surround it can range from 4 to 12 (read as an indication of an area size). Respectfully, Applicant’s last amended claim limitation is broad and the term “indicate” needs to be better defined. It is clear Hu teaches of centering the target sub-pixel and the number (size) of surrounding sub-pixels can be varied. It is based on this number to determine the display mode.
