Response to Arguments
2. Applicant contends that, “Feng fails to teach or suggest "wherein the controller is configured to supply a fixed data voltage to the first area and the second area, adjust the low voltage applied to the first area and the low voltage applied to the second area, and detect low voltages at which preset luminance is measured in the areas as the first low voltage and the second low voltage," as recited in claim 1”
Examiner respectfully disagrees. In paragraph [0068], Feng discloses that the second power supply includes a low voltage, ELVSS. Paragraph [0113] of Feng further discusses that adjusting the second power supply in the first pixel region 10 and the second pixel region 20 in order to provide a uniform luminance in both the first pixel region 10 and the second pixel region 20. Note that providing the uniform luminance could be a uniform luminance for a background image formed by a fixed data voltage.
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.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed 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 (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.
3. Claim(s) 1-3 and 8-10 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Feng et al (US 2022/0157236).

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.
4. Claim(s) 7 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Feng et al (US 2022/0157236) in view of Lee (US 2022/0208090).
As to claim 7, Feng does not teach the optical compensation system as claimed.
However, Lee teaches the optical compensation system, wherein the controller is configured to store the optical compensation values in an internal memory of the display device through the driver ([0044] The deterioration compensating unit 150 modulates the input image data Idata of each sub pixel SP at present frame based on gain value of a look-up table stored in the memory 160 and then supplies the modulated image data Mdata to the timing controlling unit 120. Further, the deterioration compensating unit 150 writes the look-up table LUT and supplies the written look-up table LUT to the memory 160 to update the look-up table of the memory 160).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Feng to teach storing the optical compensation values, as suggested by Lee. The motivation would have been in order to “provide a display device capable of improving the efficiency of image compensation by measuring the luminance of an actual image and updating a lookup table” ([0006]).
As to claim 14, Feng does not teach the optical compensation method as claimed.
However, Lee teaches the optical compensation method, further comprising storing the optical compensation values in an internal memory of the display device ([0044] The deterioration compensating unit 150 modulates the input image data Idata of each sub pixel SP at present frame based on gain value of a look-up table stored in the memory 160 and then supplies the modulated image data Mdata to the timing controlling unit 120. Further, the deterioration compensating unit 150 writes the look-up table LUT and supplies the written look-up table LUT to the memory 160 to update the look-up table of the memory 160).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Feng to teach storing the optical compensation values, as suggested by Lee. The motivation would have been in order to “provide a display device capable of improving the efficiency of image compensation by measuring the luminance of an actual image and updating a lookup table” ([0006]).
Allowable Subject Matter
5. Claims 5-6, 12 and 13 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
