Office Action

§102
DETAILED ACTION Status of Application Claims 1-19 are pending in the instant application. 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 . 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: 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. Claims 1-19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hyun et al. (US 20200394964 A1). Regarding claim 1, Hyun teaches a display panel comprising: a first region including a plurality of pixels having a first pixel density; (Figs. 1 and 3. First region DA2. Para 57. The second display area DA2 may occupy most of the display area DA. The second display area DA2 may have a second pixel density, and the second pixel density may be greater than the first pixel density.) a second region including a plurality of pixels having a second pixel density that is lower than the first pixel density; (Fig 3. Second region DA1. Para 57. (Figs. 1 and 3. First region DA2. Para 57. The second display area DA2 may occupy most of the display area DA. The second display area DA2 may have a second pixel density, and the second pixel density may be greater than the first pixel density.) a boundary region including a plurality of pixels having a third pixel density that is higher than the second pixel density and equal to the first pixel density; (Fig. 3. The boundary region is the edge region of DA2 adjacent to region DA3. So it has a third pixel density that is higher than the second pixel density of DA1 and equal to the first pixel density of DA2) the boundary region including a plurality of unit emission regions, (Para 54. OLED display which have emission pixels.) the boundary region including a plurality of unit emission regions in which a maximum value among luminance values of respective pixels gradually changes. (Para 3 discloses displaying of image. So depending on the image being displayed, different grayscale may be required of for different pixels, therefore a maximum value among luminance values of respective pixels would gradually change.) and a transition region including a plurality of pixels having a fourth pixel density that is higher than the second pixel density and lower than the third pixel density, (Fig. 3. Transition region DA3. Para 60. Also, the pixel density of the third display area DA3 may be higher than the first pixel density and lower than the second pixel density.) wherein a boundary between the boundary region and the transition region includes an inflection point where a luminance gradient of pixels changes. (Fig. 3, the boundary between DA2 and DA3. Para 61: Since the pixel density of the third display area DA3 gradually increases in a direction closer to the second display area DA2, a luminance difference between the first and second display areas DA1 and DA2 may gradually change in the third display area DA3. Therefore, a sudden luminance change between the first display area DA1 and the second display area DA2 may not be perceived by the user, and image quality may be improved.) Regarding claim 2, Hyun already teaches the display panel of claim 1, And Hyun teaches wherein in the boundary region, the maximum value among the luminance values of respective pixels gradually decreases in a direction toward the first region from the boundary region.

The pixel in top row is the third-first unit emission region, and the pixel in the row below is third-second unit emission region which is closer to DA2) and a difference between a maximum value among luminance values of respective pixels arranged in the third-first unit emission region and a maximum value among luminance values of respective pixels arranged in the first unit emission region is greater than a difference between a maximum value among luminance values of respective pixels arranged in the third-second unit emission region and the maximum value among the luminance values of the respective pixels arranged in the first unit emission region. (Para 3. So depending on the image being displayed, different grayscale may be required of for different pixels, so a difference between a maximum value among luminance values of respective pixels arranged in the third-first unit emission region and a maximum value among luminance values of respective pixels arranged in the first unit emission region is greater than a difference between a maximum value among luminance values of respective pixels arranged in the third-second unit emission region and the maximum value among the luminance values of the respective pixels arranged in the first unit emission region) Regarding claim 11, Hyun already teaches the display panel of claim 1, And Hyun further teaches wherein a maximum value among luminance values of the respective pixels arranged in the second region is greater than a maximum value among luminance values of the respective pixels arranged in the first region, the boundary region, and the transition region.
