Claim 1: Kwon discloses a display apparatus comprising: a substrate; a first pixel electrode ( Fig. 4B #210) disposed over the substrate ( Fig. 4B #110), wherein a distance from a first portion of an upper surface of the first pixel electrode to an upper surface of the substrate is greater ( [0109] second insulating layer #118 may have a first thickness h1, which is a greatest thickness, around the via hole VH ) than a distance from a second portion of the upper surface of the first pixel electrode to the upper surface of the substrate ( [0109] the second insulating layer #118 may have a second thickness h2, which is less than the first thickness h1, in an area farther away, or distal from the via hole VH ).
Kwon does not appear to disclose in (Fig. 4B) a data line disposed over the substrate and extending in a first direction; and an insulation layer covering the data line, wherein the first pixel electrode is disposed over the insulation layer, and, when viewed from a direction perpendicular to the substrate, a line connecting a central portion of the first portion of the upper surface of the first pixel electrode and a central portion of the second portion of the upper surface of the first pixel electrode forms an acute angle with the first direction.
However, Kwon teaches in Figs. 6A and 6B a data line ( Fig. 6A: WL1; [00137] In an embodiment, the first wiring WL1 and the second wiring WL2 may be data lines ) disposed over the substrate ( [ 0130] In Figs. 6A and 6B, the same reference numerals as those in Figs. 4A and 4B refer to the same or like elements; Fig. 4B #110 same as Fig. 6B #110 which isn’t shown ) and extending in a first direction ( Fig. 6A: WL1 extends in the same direction as the data line #1710 of Figure 10 in the application ); and an insulation layer ( Fig. 6B #118 ) covering the data line ( Fig. 6B: WL1 ), wherein the first pixel electrode ( Fig. 6B #210 ) is disposed over the insulation layer ( Fig. 6B #118 ), and, when viewed from a direction perpendicular to the substrate ( Fig. 6A top down view ), a line connecting a central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 6A #210 ) and a central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6A center of #210) forms an acute angle with the first direction ( Fig. 6A shows an acute angle in #210 ).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kwon in Figs. 6A and 6B with Kwon in Fig. 4B to implement a data line disposed over the substrate and extending in a first direction; and an insulation layer covering the data line, wherein the first pixel electrode is disposed over the insulation layer, and, when viewed from a direction perpendicular to the substrate, a line connecting a central portion of the first portion of the upper surface of the first pixel electrode and a central portion of the second portion of the upper surface of the first pixel electrode forms an acute angle with the first direction because this approach can prevent optical interference in touch sensitive displays.
Claim 3: Kwon discloses in (Fig. 4B) and (Figs. 6A and 6B) the display apparatus of claim 1 (as discussed above).
Kwon does not appear to disclose in (Fig. 4B) when viewed from the direction perpendicular to the substrate, the line connecting the central portion of the first portion of the upper surface of the first pixel electrode and the central portion of the second portion of the upper surface of the first pixel electrode forms an angle of about 45 degrees with the first direction.
However, Kwon teaches in Figs. 6A and 6B when viewed from the direction perpendicular to the substrate ( Fig. 6A view), the line connecting the central portion of the first portion of the upper surface of the first pixel electrode (Fig. 6A #210) and the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6A #210) forms an angle of about 45 degrees with the first direction ( as shown in Fig. 6A ).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kwon in Figs. 6A and 6B with Kwon in Fig. 4B to implement when viewed from the direction perpendicular to the substrate, the line connecting the central portion of the first portion of the upper surface of the first pixel electrode and the central portion of the second portion of the upper surface of the first pixel electrode forms an angle of about 45 degrees with the first direction because a 45 degree angle is a critical design feature used to improve image quality.
Claim 4: Kwon discloses in (Fig. 4B) and (Figs. 6A and 6B) the display apparatus of claim 1 ( as discussed above).
Kwon does not appear to disclose in (Fig. 4B) when viewed from the direction perpendicular to the substrate, the central portion of the second portion of the upper surface of the first pixel electrode is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode, and the central portion of the second portion of the upper surface of the first pixel electrode is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode.
However, Kwon teaches in Figs. 6A and 6B when viewed from the direction perpendicular to the substrate ( Fig. 6B view), the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6B #210 raised portion is closer to WL1 and WL2) is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 6B #210 first portion is further away from WL1 and WL2), and the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6A shows the central portion of #210) is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 6A the central part of #210 is in parallel with WL1 and WL2 in the first direction ).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kwon in Figs. 6A and 6B with Kwon in Fig. 4B to implement when viewed from the direction perpendicular to the substrate, the central portion of the second portion of the upper surface of the first pixel electrode is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode, and the central portion of the second portion of the upper surface of the first pixel electrode is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode because this positioning would improve the pixel’s electrical efficiency and reduce optical interference.

Claims 7 and 8 are rejected under U.S.C. 103 as being unpatentable over Kwon et al.; US 2021/0126065 A1; 04/2020 using Fig. 4B in view of Kwon et al.; US 2021/0126065 A1; 04/2020 using Figs. 6A and 6B as applied to claim 5 above, and further in view of Kim et al.; US 2021/0064169 A1; 04/2020

However, Kim teaches when viewed from the direction perpendicular to the substrate, the first conductive layer ( Fig. 14 TS-CL1 is connected to TS-CL2 ) has a chamfered line ( Fig. 14 TS-CL2 has a chamfered line ) extending in a direction crossing the line connecting the central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 14 TS-CL2 connects to TS-PD12) and the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 14 TS-CL2 connects to TS-PD2) to each other ( [0166] As a result the first sensing pad parts TS-PD12 may be electrically connected to the second sensing pad parts TS-PD2).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kim with Kwon in Figs. 6A and 6B and Kwon in Fig. 4B to implement when viewed from the direction perpendicular to the substrate, the first conductive layer has a chamfered line extending in a direction crossing the line connecting the central portion of the first portion of the upper surface of the first pixel electrode and the central portion of the second portion of the upper surface of the first pixel electrode to each other because a chamfered (or beveled line) on a conductive layer crossing a pixel electrode has a primary purpose to control the electrical field within the pixel to improve performance, brightness and manufacturing yield.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kim with Kwon in Figs. 6A and 6B and Kwon in Fig. 4B to implement when viewed from the direction perpendicular to the substrate, the chamfered line is perpendicular to the line connecting the central portion of the first portion of the upper surface of the first pixel electrode and the central portion of the second portion of the upper surface of the first pixel electrode to each other because combining a chamfered line with a 45 degree angled electrode is an advanced design used to improve display brightness, response time, and overall viewing angle.

However, Kwon teaches in (Fig. 8) a data line ( Fig. 8 WL1 ) disposed over the substrate ( [0142] Fig.8 is a schematic layout diagram illustrating a relationship between emission areas, pixel electrodes, and wirings arranged below the pixel electrodes in a plurality of pixels, according to an embodiment ) and extending in a first direction ( Fig. 8: WL1 extends in the same direction as the data line #1710 of Figure 10 in the application ); an insulation layer ( Fig. 4B #118 ) covering the data line (Fig. 8 WL1 ); a second pixel electrode ( Fig. 8: green electrode G ) disposed over the insulation layer ( Fig. 4B #118 ); and a pixel-defining layer ( Fig. 4B pixel defining layer #119 ) covering an edge of each of the first pixel electrode ( Fig. 8: red R) and the second pixel electrode ( Fig. 8: G), wherein the first pixel electrode ( Fig. 8: R ) is disposed over the insulation layer ( Fig. 4B #118), and, when viewed from a direction perpendicular ( Fig. 8 top down view) to the substrate ( Fig. 4B #110 ), a line connecting a central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 8: R) and a central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 8 center of R ) forms an acute angle with the first direction ( Fig. 8 shows acute angle in R).

Claims 10, 17, and 18 are rejected under U.S.C. 103 as being unpatentable over Kwon et al.; US 2021/0126065 A1; 04/2020 using Fig. 4B in view of Kwon et al.; US 2021/0126065 A1; 04/2020 using Fig. 8 as applied to claim 9 above, and further in view of Kim et al.; US 2021/0064169 A1; 04/2020

Claim 13 is rejected under U.S.C. 103 as being unpatentable over Kwon et al.; US 2021/0126065 A1; 04/2020 using Fig. 4B and Fig. 8 in view of Kim et al.; US 2021/0064169 A1; 04/2020 as applied to claim 10 above, and further in view of Cai et al.; US 2022/0320851 A1; 06/2021

Kwon discloses in Fig. 4B when viewed from the direction perpendicular to the substrate ( Fig. 4B: looking perpendicular from #110 ) , the first conductive layer ( Fig. 4B: CL) does not overlap the second portion ( Fig. 4B: portion of #210 at height h2 ) of the upper surface of the first pixel electrode ( Fig. 4B #210)
Neither Kwon nor Kim appear to disclose a length of the second conductive layer in the first direction is greater than a length, in the first direction, of an exposed portion of the second pixel electrode, which is not covered with the pixel-defining layer.
However, Cai teaches a length of the second conductive layer ( Fig. 5: SD2) in the first direction is greater than a length ( Fig. 5: SD2 is longer than #31 in the first direction), in the first direction, of an exposed portion of the second pixel electrode ( Fig. 5: #31), which is not covered with the pixel-defining layer ( Fig. 5: SD2 is longer than the portion of #31 in the center that is not covered by PDL).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Cai with Kwon in Fig. 4B and Figs. 8 and Kim to implement a length of the second conductive layer in the first direction is greater than a length, in the first direction, of an exposed portion of the second pixel electrode, which is not covered with the pixel-defining layer because the extended common electrode can act as a shield blocking stray electric fields from the data line
Claim 14 is rejected under U.S.C. 103 as being unpatentable over Kwon et al.; US 2021/0126065 A1; 04/2020 using Fig. 4B and Fig. 8 in view of Kim et al.; US 2021/0064169 A1; 04/2020 as applied to claim 10 above, and further in view of Ka et al.; US 2020/0058725 A1; 08/2019

Neither Kwon in (Fig. 4B) and (Fig.8) nor Kim appear to disclose when viewed from the direction perpendicular to the substrate, the central portion of the second portion of the upper surface of the first pixel electrode is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode, and the central portion of the second portion of the upper surface of the first pixel electrode is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode.
However, Kwon teaches in (Figs. 6A and 6B) wherein, when viewed from the direction perpendicular to the substrate ( Fig. 6B view), the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6B #210 raised portion is closer to WL1 and WL2) is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 6B #210 first portion is further away from WL1 and WL2), and the central portion of the second portion of the upper surface of the first pixel electrode ( Fig. 6A shows the central portion of #210) is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode ( Fig. 6A the central part of #210 is in parallel with WL1 and WL2 in the first direction ).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to utilize the teachings of Kwon in (Figs. 6A and 6B) with Kwon in (Fig. 4B) and (Fig. 8) and Kim to implement when viewed from the direction perpendicular to the substrate, the central portion of the second portion of the upper surface of the first pixel electrode is positioned closer to the data line than the central portion of the first portion of the upper surface of the first pixel electrode, and the central portion of the second portion of the upper surface of the first pixel electrode is positioned in the first direction from the central portion of the first portion of the upper surface of the first pixel electrode because this positioning would improve the pixel’s electrical efficiency and reduce optical interference.
Response to Amendment
Applicant’s arguments, see page 10 of remarks, filed 12/17/2025, with respect to Figure 11 have been fully considered and are persuasive. The objection of 09/05/2025 has been withdrawn.
Applicant's arguments filed 12/17/2025 have been fully considered but they are not persuasive. The amendment to Claim 1 is covered by the rejection of Claim 2 which is added to claim 1 in it's entirety.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
