Regarding claim 1, Won teaches a display apparatus (fig. 1) comprising:

wherein the deterioration compensator is configured to compensate the rendered image data for the viewing angle control pixel based on the first age and compensate the rendered image data for the normal pixel based on the second age (fig. 4, The grayscale value compensator 228 and Para 0095, wherein grayscale value compensator 228 may compensate the grayscale value GIN of the input image data IMG based on the first stress data SD1 and the second stress data SD2 and may output the compensated grayscale value GOUT, Kim).
Regarding claim 10, Won in view of Kim teaches the display apparatus of claim 1, wherein the display panel comprises: a first color first normal pixel disposed in a first pixel row; a second color 1-1 normal pixel and a second color 1-2 normal pixel sequentially disposed in a second pixel row (fig. 5 and Para 0072, Won);
Won in view of Kim a first color first viewing angle control pixel, a third color first normal pixel and a first color second viewing angle control pixel sequentially disposed in a third pixel row; a second color 1-1 viewing angle control pixel, a second color 1-2 viewing angle control pixel, a second color 2-1 viewing angle control pixel and a second color 2-2 viewing angle control pixel sequentially disposed in a fourth pixel row; a third color first viewing angle control pixel, a first color second normal pixel and a third color second viewing angle control pixel sequentially disposed in a fifth pixel row; a second color 2-1 normal pixel and a second color 2-2 normal pixel sequentially disposed in a sixth pixel row; and a third color second normal pixel disposed in a seventh pixel row.
However, WON teaches in FIG. 2 and Para 0065, wherein the display panel 100 may include the first pixels 101 and the second pixels 102. The display panel 100 may have a structure in which the first pixels 101 are surrounded by the second pixels 102, and the second pixels 102 are surrounded by the first pixels 101. Such a structure may be repeatedly arranged in the display panel 100. In FIG. 5 and Para 0072, wherein the normal pixel 110 may include a plurality of sub-pixels 111. The sub-pixels 111 of the normal pixel 110 may include a light emitting region 130. The sub-pixels 111 of the normal pixel 110 may include a plurality of the light emitting regions 130. The light emitting region 130 may include a red (R) light emitting region 130a, a green (G) light emitting region 130b, and a blue (B) light emitting region 130c. In FIG. 7 and Para 0076, wherein each of the private pixels 120 may include a plurality of sub-pixels 121. he light emitting regions 130 may include a red (R) light emitting region 130a, a green (G) light emitting region 130b, and blue (B) light emitting region 130c.

Further the terms, 1-1 and 1-2 viewing angle is not a known term in the art and the specification does not further define this term with regards to the subpixel, thus any additional sub pixels would read on this term). Therefore it would have been obvious to one of ordinary skill in the art at the time of filing to modify WON to have additional sub pixels in the private pixels for better control of the image quality and viewing angle control in the private mode.
However WON teaches the subpixels arranged in (See; Figs 2, 5 and 7) which could reasonable be considered to be arrangement of the subpixels. Further since the disclosure offers no criticality and no unexpected results from having subpixels disposed in a specific arrangement then it is deemed a design choice. Therefore it would have obvious to one of ordinary skill in the art at the time of filing to use a arrangement as a mere design choice based on the specific device that it will be used for.

It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have modified a display apparatus of Won in view of Kim by applying the teaching of Lee to include pixels arranged in rows and covered with a first lens LENS1 and a second lens LENS2 which may be implemented as a transparent medium or transparent insulating layer pattern disposed in the display panel to switch between SMODE and PMODE, and to provide a display device that is capable of adjusting the viewing angle in each of the pixels and preventing image quality degradation when the viewing angle is changed (Para 0008, Lee)
Regarding claim 13, Won in view of Kim and in view of Lee teaches the display apparatus of claim 12, wherein, in a normal mode, the first color first normal pixel, the second color first normal pixel, the third color first normal pixel, the first color second normal pixel, the second color second normal pixel and the third color second normal pixel are configured to emit light (fig. 3 and Para 0067, wherein in a first mode (normal mode), may drive both the first pixels 101 (a normal pixel) and the second pixels 102 (a private pixel), Won),
wherein, in the normal mode, the first color first viewing angle control pixel, the second color first viewing angle control pixel, the third color first viewing angle control pixel, the first color second viewing angle control pixel, the second color second viewing angle control pixel and the third color second viewing angle control pixel are configured to emit light (fig. 3 and Para 0067, wherein in a first mode (normal mode), may drive both the first pixels 101 (a normal pixel) and the second pixels 102 (a private pixel), Won),
wherein, in a private mode, the first color first normal pixel, the second color first normal pixel, the third color first normal pixel, the first color second normal pixel, the second color second normal pixel and the third color second normal pixel are configured not to emit light (fig. 4 and Para 0069, wherein in a second mode (the private mode), may drive the second pixels 102 (a private pixel) in a first part for one frame, the second pixel 102 may be driven more than the first pixel 101 Won), and
wherein, in the private mode, the first color first viewing angle control pixel, the second color first viewing angle control pixel, the third color first viewing angle control pixel, the first color second viewing angle control pixel, the second color second viewing angle control pixel and the third color second viewing angle control pixel are configured to emit light (fig. 4 and Para 0069, wherein in a second mode (the private mode), may drive the second pixels 102 (a private pixel) in a first part for one frame, the second pixel 102 may be driven more than the first pixel 101 Won).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Park (US 2021/0056912), relate generally to a data compensation. More particularly, embodiments of the invention relate to a data compensating circuit that performs a data compensation such as afterimage compensation, an optical compensation, etc., and a display device including the data compensating circuit.
Lee (US 2018/0012563), relates to a method of displaying an image by using a display device. The method includes: grouping pixels included in a display unit into pixel blocks, generating a first accumulated stress map representing a degree of a deteriorated performance of the pixels included in the pixel blocks based on first image data of a current frame image, and determining a shiftable range of the current frame image by analyzing the first accumulated stress map. The first image data is corrected to second image data in which the current frame image is shifted within the shiftable range.
