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 factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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.
Claim 34 are rejected under 35 U.S.C. 103 as being unpatentable over Ohchi (US 2020/0135820) as applied to claim 31 above, and further in view of Song et al. (US 2015/0349291).
Regarding claim 34, Ohchi fails to expressly disclose:
The display panel according to claim 31, wherein the at least one encapsulation layer comprises a plurality of encapsulation layers, the first encapsulation layers of the plurality of encapsulation layers are arranged at intervals at the isolation structure, and the first encapsulation layers and the light-emitting units are in a one-to-one correspondence; and
the first encapsulation layer is in contact with a side of the light-emitting unit away from the array base plate and covers a side wall of the isolation structure, the first encapsulation layer extends to a side surface of the isolation structure away from the array base plate and forms a gap with the side surface of the isolation structure away from the array base plate, and the light filtering layer is partially located in the gap.
However, Song teaches an organic LED structure with an encapsulation layer 3 that is patterned to correlate with the light emitting layer 5, and within which a light filtering layer 10 is formed.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the structure of Ohchi to include the multi-layered packaging and encapsulation structure of Song for the predictable advantage of providing pixel isolation in a conventional and well known manner.
Claims 36 and 37 are rejected under 35 U.S.C. 103 as being unpatentable over Ohchi (US 2020/0135820) as applied to claim 31 above, and further in view of Hung et al. (US 2020/0057520).
Regarding claim 36, Ohchi fails to expressly disclose:
The display panel according to claim 31, further comprising a touch layer, wherein the light filtering layer is arranged on a side of the touch layer close to the array base plate.
However, Hung teaches the use of an AMOLED display integrated with a touch layer (FIG. 3).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to integrate a touch layer with the display of Ohchi as taught by Hung for the further advantage of enabling a touch sensitive display in a conventional and predictable manner.
Regarding claim 37, Ohchi fails to expressly disclose:
The display panel according to claim 36, further comprising a second light blocking layer arranged on a side of the touch layer away from the array base plate, wherein the second light blocking layer comprises a second body portion and a second aperture, the second aperture is arranged opposite to the isolation opening, and an orthographic projection of the second body portion on the array base plate covers an orthographic projection of the isolation structure on the array base plate.
However, Hung teaches the use of an AMOLED display integrated with a touch layer (FIG. 3) and having multiple anti-reflective portions.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to integrate a touch layer with the display of Ohchi as taught by Hung for the further advantage of enabling an antireflective touch sensitive display in a conventional and predictable manner.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
US 2015/0357388 teaches multi-layered isolation structures having larger orthographic projections in layers further from the base
US 2006/0170340 teaches multi-layered isolation structures having larger orthographic projections in layers further from the base
