DETAILED ACTION
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 .
Response to Amendment
Acknowledgment is made that applicant's Amendment, filed on April 22nd, 2026, has been entered.
Upon entrance of the Amendment, claim 15 was amended. Claims 1-20 are currently pending.
Claim 15 was objected to because of informalities. Claim 15 has been amended as suggested. The objections of claim 15 has been overcome and is withdrawn.
Response to Arguments
Applicant's arguments filed April 22nd, 2026 have been fully considered but they are not persuasive.
The Applicant has argued:
Claim 1 recites at least in part the following distinguishing features:
"a first light-shielding structure located in the bank disposition region and on a side
of the first light-emitting portion facing the substrate" (Hereinafter referred to as Features-A for simplicity);
"wherein the first light-emitting portion and the first light-shielding structure at least partially overlap along a thickness direction of the display panel (Hereinafter referred to as Features-B for simplicity);
… neither Choi nor Zhai discloses or teaches Features-A or Features-B, whether considered individually or in combination….
Choi and Zhai address different technical problems and disclose structurally different solutions. Accordingly, a person of ordinary skill in the art would not have been motivated to modify Choi in view of Zhai to arrive at the claimed Features-A and Features-B, absent impermissible hindsight. Hence, claim 1 involves an inventive step and is patentable over Choi and Zhai, whether taken alone or in combination.
The arguments are not persuasive, by the following reasons:
The Office Action stated that “Choi does not disclose a first light-shielding structure located in the bank disposition region and on a side of the first light-emitting portion facing the substrate.” This claimed Feature-A is cured by Zhai.
Zhai does disclose a first light-shielding structure located in the bank disposition region and on a side of the first light-emitting portion facing the substrate (Fig. 5, light-shielding structure 0162 is located in the bank disposition region and “on” a side of the first light-emitting portion 013 facing the substrate. Please note that the word “on” is not interpreted as direct contact or vertical overlap). This cures the missing of Feature-A.
As seen in Fig. 17, Choi discloses the light emitting layer presents on both display region and non-display portion. The non-display region includes the bank disposition region and on a side of the first light-emitting portion facing the substrate.
As being modified, first light-shielding structure is located on the non-display region.
As a result, the first light-emitting portion and the first light-shielding structure at least partially overlap along a thickness direction of the display panel.
The claimed Feature-B was met as a result of modify Choi in view of Zhai.
Zhai was used as secondary refences for curing Feature-A. Zhai does not have to disclose Feature B, otherwise Zhai would be used for a 102 rejection.
Claim Rejections - 35 USC § 103
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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-2, 11-13, and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Choi et al. (U.S. Patent No. 11,417,864) in view of Zhai U.S. Patent No. 11,217,575).
Regarding to claim 1, Choi teaches a display panel, comprising a display region (Figs. 17-18, element DA) and a non-display region (Figs. 18-19, element OA/MA), wherein the display region surrounds at least part of the non-display region (Fig. 18);
the non-display region comprises an element disposition region (Figs. 17-18, element OA; column 4, lines 66-67) and a bank disposition region surrounding at least part of the element disposition region (Figs. 17-18, element MA), and the bank disposition region is provided with a bank (Figs. 17-18, element 510); and
the display panel further comprises:
a substrate (Fig. 17, element 101), wherein the bank is disposed on a side of the substrate (Fig. 17);
a light-emitting layer (Fig. 17, element 222; column 11, lines 28-33) located on a side of the bank facing away from the substrate and comprising a first light-emitting portion located in the bank disposition region (Fig. 17, portion of layer 222 in the bank region).
Choi does not disclose a first light-shielding structure located in the bank disposition region and on a side of the first light-emitting portion facing the substrate, wherein the first light-emitting portion and the first light-shielding structure at least partially overlap along a thickness direction of the display panel.
Zhai discloses a first light-shielding structure located in the bank disposition region and on a side of the first light-emitting portion facing the substrate (Fig. 5, element 0162, column 8, line 64). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Choi in view of Zhai to locate a first light-shielding structure in the bank disposition region and on a side of the first light-emitting portion facing the substrate in order to prevent interference. Choi as modified having the first light-shielding structure overlap the bank along a thickness direction of the display panel. As a result, the first light-emitting portion and the first light-shielding structure at least partially overlap along a thickness direction of the display panel, because the first light-emitting portion is on top of the bank (Fig. 17).
