Regarding claim 17, Lee, as modified by Dong and Park, teaches claim 16 from which claim 17 depends. Lee further teaches
the peripheral area (NDA2).
Lee, Dong, and Park do not expressly disclose the other limitations of claim 17.
However, in an analogous art, Hayashi teaches
(Currently Amended) The display panel of claim 16, further comprising:
a third voltage supply line (LB – Fig. 3 – [0049] – “power lines include main
power lines LR, LG, and LB”) the peripheral area,
wherein the plurality of third vertical voltage lines (Lb2) in the display area
(DA) are electrically connected to the third voltage supply line (Lb2 – Fig. 3 – [0050] – “second sub-power lines Lr2, Lg2, and Lb2 are provided so as to be parallel in a column direction”) in the peripheral area.
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the third voltage lines structure as taught by Hayashi into Lee, Dong, and Park.
An ordinary artisan would have been motivated to use the known technique of Hayashi in the manner set forth above to produce the predictable result as stated above in claim 12.
Regarding claim 18, Lee, as modified by Dong and Park, teaches claim 16 from which claim 18 depends. Lee, Dong, and Park do not expressly disclose the limitations of claim 18.
However, in an analogous art, Hayashi teaches
(Currently Amended) The display panel of claim 16, wherein
one of the plurality of first vertical voltage lines (Lr2) is
first pair of adjacent pixel areas (26 – Fig. – [0065] – “the pixel area 26 of the organic EL device”), and
one of the plurality of third vertical voltage lines (Lg2) is a second (26).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the third voltage lines structure as taught by Hayashi into Lee, Dong, and Park.
An ordinary artisan would have been motivated to use the known technique of Hayashi in the manner set forth above to produce the predictable result as stated above in claim 12.
Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Dong, Park, Hayashi, and Yang et al. (US 20230028746 A1 – hereinafter Yang-746).
Regarding claim 15, Lee, as modified by Dong, Park, and Hayashi, teaches claim 13 from which claim 15 depends. Lee, Dong, Park, and Hayashi do not expressly disclose the limitations of claim 15.
However, in an analogous art, Yang-746 teaches
(Currently Amended) The display panel of claim 13, wherein
the first number of columns is greater than the second number (the number
of first vertical voltage lines is greater than the number of second vertical voltage lines as defined below) of columns,
one of the plurality of first vertical voltage lines (005a and 006a – Fig. 1A –
[0035] – {“first voltage line 005 includes a first portion 005a and a second portion 005b. The first portion 005a extends in a column direction”}, {“Similarly, the second voltage line 006 includes a first portion 006a and a second portion 006b. The first portion 006a extends in the column direction”}) is first pair of adjacent pixel areas (002 – Fig. 1A – [0033] – “light-emitting unit 002 includes a driving circuit and a plurality of light-emitting elements” – this is a pixel area), and
one of the plurality of second vertical voltage lines (0061 – Fig. 1B – [0039] – “additional voltage lines 0061”) is a second (002).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the voltage lines column structure as taught by Yang-746 into Lee, Dong, Park, and Hayashi.
An ordinary artisan would have been motivated to use the known technique of Yang-746 in the manner set forth above to produce the predictable result [0033] – “each light-emitting unit 002 includes a driving circuit and a plurality of light-emitting elements.”
To do so would have merely been to apply a known technique to a known device ready for improvement to yield predictable results, KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007), MPEP 2143 I. D.
Claim 19 is rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Dong, Park, Lai, and Yang et al. (CN 112289267 A – hereinafter Yang-267).
Regarding claim 19, Lee, as modified by Dong and Park, teaches claim 16 from which claim 19 depends. Lee further teaches
(Currently Amended) The display panel of claim 16, wherein each
pixel circuit (PXC) of the plurality of pixel circuits (PXC) comprises:

Lee, Dong, and Park do not expressly disclose the limitations of claim 19.
However, in an analogous art, Lai teaches
a second capacitor (C3 – Fig. 1 – [0026] – “third capacitor (C3)”) comprising a third electrode ([0026] – “a second pole plate of the third capacitor (C3) is connected to the third node (N3)” – node N3 is connected to T2, hereinafter ‘3E’) ([0026] – “first pole plate of the third capacitor” – hereinafter ‘4E’) above the third electrode (3E); [[and]]
a third capacitor (C2 – Fig. 1 – [0026] – “second capacitor (C2)”) comprising a fifth electrode ([0026] – “a second pole plate of the second capacitor (C2) is connected to the second node (N2)” – node N2 is connected to T1, hereinafter ‘5E’) ([0026] – “first pole plate of the second capacitor” – hereinafter ‘6E’) above the fifth electrode (5E),

wherein the third electrode of the second capacitor (C3) is electrically connected to the first semiconductor layer, and the fifth electrode of the third capacitor (C2) is electrically connected to the second semiconductor layer.
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the capacitor structure as taught by Lai into Lee, Dong, and Park.
An ordinary artisan would have been motivated to use the known technique of Lai in the manner set forth above to produce the predictable result as stated above in claim 6.
Lee, Dong, Park, and Lai do not expressly disclose the limitations of claim 19.
However, in an analogous art, Yang-267 teaches
wherein the third electrode of the second capacitor is electrically connected to the first semiconductor layer ([0043] – “The initialization signal line Ref at the overlap position with the active layer of the first sub-transistor T11 and the second sub-transistor T12 in series serves as one plate of the first coupling capacitor C1, and the active layer of the first sub-transistor T11 and the second sub-transistor T12 in series serves as the other plate of the first coupling capacitor C1”), and the fifth electrode of the third capacitor is electrically connected to the second semiconductor layer ([0043] teaches this connection).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the electrical connection structure as taught by Yang-267 into Lee, Dong, Park, and Lai.
An ordinary artisan would have been motivated to use the known technique of Yang-267 in the manner set forth above to produce the predictable result of [0033] – “In order to make the light-emitting element emit light, a first voltage signal needs to be provided to a first voltage terminal 003 of each light-emitting unit 002, and a second voltage signal needs to be provided to a second voltage terminal 004 of each light-emitting unit 002.”
To do so would have merely been to apply a known technique to a known device ready for improvement to yield predictable results, KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007), MPEP 2143 I. D.
Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Dong, Park, Lai, Yang-267, and Dokania et al. (US 20230284456 A1 – hereinafter Dokania).
Regarding claim 20, Lee, as modified by Dong, Park, Lai, and Yang-267 teaches claim 19 from which claim 19 depends. Lee further teaches
the second electrode (Cst2) of the first capacitor (Cst).
Lee, Dong, Park, and Yang-267 do not expressly disclose the limitations of claim 20.
However, in an analogous art, Lai teaches
(Currently Amended) The display panel of claim 19, wherein
the third electrode (3E) of the second capacitor (C1) and the fifth electrode
(5E) of the third capacitor (C2) each include a semiconductor material, and
the second electrode of the first capacitor, the fourth electrode (4E), of the second capacitor (C1) and the sixth electrode (6E) of the third capacitor (C2) are integral with each other and are electrically connected to the driving voltage line (PVDD).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the capacitor structure as taught by Lai into Lee, Dong, and Park.
An ordinary artisan would have been motivated to use the known technique of Lai in the manner set forth above to produce the predictable result as stated above in claim 6.
Lee, Dong, Park, Yang-267, and Lai do not expressly disclose the limitations of claim 20.
However, in an analogous art, Dokania teaches
are integral with each other ({[0687] – “the metal plane is coupled to individual bottom electrodes of the first capacitor, the second capacitor, the third capacitor”}, {[0310] – “capacitors on shared electrode 1301 or metal plane 1401”} the capacitors share an electrode therefore are integral to each other).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to integrate the capacitor structure as taught by Dokania into Lee, Dong, Park, Yang-267, and Lai.
An ordinary artisan would have been motivated to use the known technique of Dokania in the manner set forth above to produce the predictable result of [0091] – “a configuration for efficiently placing a group of capacitors that have one terminal connected to a common node.”
