Therefore, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Park with Suzuki teachings by including “a display driver configured to drive the display panel to display a test image on the display panel, and upon receiving a correction coefficient for each of a plurality of viewpoints of the display panel based on the display of the test image, to correct image data using the correction coefficient for each of the plurality of viewpoint of the display panel” because this combination has the benefit of providing display device capable of correcting multi-viewpoint images with high accuracy[See Suzuki: at least par. 1-17].
Park and Suzuki do not explicitly disclose upon receiving a correction coefficient for each of a plurality of viewpoints of the display panel based on the display of the test image, to correct image data using the correction coefficient for each of the plurality of viewpoints of the display panel, wherein the plurality of viewpoints of the display panel are set according to relative positions of the sub-pixels overlapping the stereoscopic lenses.
However, Hwang teaches upon receiving a correction coefficient for each of a plurality of viewpoints of the display panel based on the display of the test image, to correct image data using the correction coefficient for each of the plurality of viewpoints of the display panel, wherein the plurality of viewpoints of the display panel are set according to relative positions of the sub-pixels overlapping the stereoscopic lenses[See Hwang: at least Figs. 1-18 and par. 62-75, 105-125 regarding At least one example embodiment may reduce (or alternatively, prevent) an occurrence of a crosstalk by calibrating an arrangement of pixels of a panel based on a current size and a current position of an optical layer although a size error and a position error exist.

Regarding claim 4, Park, Suzuki and Hwang teach all of the limitations of claim 2, and are analyzed as previously discussed with respect to that claim. Further on, Park and Suzuki teach or suggest wherein the display driver generates corrected image data for each of the plurality of viewpoints by multiplying the correction coefficient for each of the plurality of viewpoints by the image data for each of the plurality of viewpoints See Suzuki: at least Figs. 22-23 and par. 129, 135-139 regarding For example, as illustrated in FIG. 22, the image of the pixel column Pt is corrected by multiplying pixels of pixel columns in the vicinity of the pixel column Pt in a range Zf, for example, the pixel columns Pk−1, Pk−1_1 to Pk−1_4, Pk, Pk_1 to Pk_4, Pk+1, and Pk+1_1 to Pk+1_4 by inverse functions (inverse filters) for integrally and simultaneously correcting the blurring caused by the crosstalk and the blurring caused by the lens MTF.

Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Park et al.(US 11,095,872 B2)(hereinafter Park) in view of SUZUKI et al.(US 2022/0191455 A1)(hereinafter Suzuki) in further view of HWANG et al.(US 2016/0150223 A1)(hereinafter Hwang) and in further view of OHYAMA(US 2021/0385431 A1)(hereinafter Ohyama).
Regarding claim 3, Park, Suzuki and Hwang teach all of the limitations of claim 2, and are analyzed as previously discussed with respect to that claim.
Park, Suzuki and Hwang do not explicitly disclose wherein the display driver generates corrected image data for each of the plurality of viewpoints by adding/subtracting the correction coefficient to/from the image data for each of the plurality of viewpoints, generates data voltages corresponding to the corrected image data, and provides the data voltages to the display panel.

The difference is obtained by comparing a partial image corresponding to each refraction means 1a (a partial image corresponding to the photographing direction of the photographing device 9) in the photographed image data and to a region image corresponding to the photographing direction of the photographing device 9 and the normal direction of each refraction means 1a in the plane image corresponding to the photographing direction of the photographing device 9. For example, it is the displacement magnitude and direction of the position between the partial image and the region image to be compared, or the difference in size and the difference in shape etc. between the partial image and the region image to be compared… Next, the control unit 56 corrects the formed-image data so that the difference between the photographed image and the plane image is reduced. For example, in the case of the displacement between the partial image and the region image to be compared, the control section 56 corrects the formed-image data based on the magnitude and direction of the displacement….].
Therefore, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify Park, Suzuki and Hwang with Ohyama teachings by including “wherein the display driver generates corrected image data for each of the plurality of viewpoints by adding/subtracting the correction coefficient to/from the image data for each of the plurality of viewpoints, generates data voltages corresponding to the corrected image data, and provides the data voltages to the display panel” because this combination has the benefit of improving the display device by providing a correction method to reduce differences[See Ohyama: at least par. 5-17, 114-115, 231, 287-295, 301].
