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 .
Claims 1-22 are currently pending in the instant application.
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:

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.
Claim(s) 4, 8, 13 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Kim as applied to claims 3, 7, 12 and 14 above, and further in view of Hauck et al. (US Patent No. 6,091,426; hereinafter “Hauck”).
As to claim 4, Kim does not disclose the electronic display of claim 3, wherein the display driver circuitry is configured to adjust the image data based on the sum of the subset of the image data differences scaled according to a programming time occurring after a target display pixel is to be programmed.
However, Hauck (Fig. 4) teaches wherein the display driver circuitry is configured to adjust the image data based on the sum of the subset of the image data differences scaled according to a programming time occurring after a target display pixel is to be programmed (50; Col. 6 lines 20-31, inputting of data is considered to be the start of the programming time).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Hauck to applying scaling in the device disclosed by Kim. The motivation would have been to perform the smoothing operation (Hauck; Col. 6 lines 19-23).
As to claim 8, Kim does not disclose the image processing circuitry of claim 7, comprising an image data difference line buffer configured to hold N+1 lines of differences.
However, Hauck (Fig. 7) teaches comprising an image data difference line buffer (103a, 103b) configured to hold N+1 lines of differences (Col. 7 lines 30-35).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Hauck to include a line buffer in the device disclosed by Kim. The motivation would have been to store the data signals (Hauck; Col. 8 lines 23-25).
As to claim 13, Kim does not disclose the method of claim 12, wherein determining the first pixel data compensation comprises scaling the difference between the first pixel data and the second pixel data based on a separation between the first line and the second line.
However, Hauck teaches wherein determining the first pixel data compensation comprises scaling the difference between the first pixel data and the second pixel data based on a separation between the first line and the second line (Fig. 4 element 50; Col. 6 lines 20-31, weighted coefficient would be applied to all pixels).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Hauck to applying scaling in the device disclosed by Kim. The motivation would have been to perform the smoothing operation (Hauck; Col. 6 lines 19-23).
As to claim 15, Kim does not disclose the method of claim 14, wherein determining the first pixel data compensation comprises scaling the difference between the second pixel data and the third pixel data based on a separation between the second line and the third line.
However, Hauck teaches wherein determining the first pixel data compensation comprises scaling the difference between the second pixel data and the third pixel data based on a separation between the second line and the third line (Fig. 4 element 50; Col. 6 lines 20-31, weighted coefficient would be applied to all pixels).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Hauck to applying scaling in the device disclosed by Kim. The motivation would have been to perform the smoothing operation (Hauck; Col. 6 lines 19-23).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant‘s disclosure.
Winzell et al. (US 2024/0153050 A1) discloses applying scaler to the pixel difference values (Para. 0075).
