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 5-8, 11,13 are rejected under 35 U.S.C. 103 as being unpatentable over Wei et al, (CN 110299469 A, machine translation 10-2019) (Wei, hereafter).
Regarding claims 5 and 6, Wei discloses(Figure 8) wherein the OLED display panel further comprises an interlayer insulating layer (no number) and a planarization layer (102); where the thermal conduction functional layer is disposed on the entire surface of the substrate(10). Wei fails to explicitly disclose wherein the thermal conduction functional layer(70) is disposed between the interlayer insulating layer (no number) and the planarization layer (102) throughout the entirety of the substrate (claim 5 and 6).
It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the Display Panel of Wei wherein the thermal conduction functional layer(70) is disposed between the interlayer insulating layer (no number) and the planarization layer (102) throughout the entirety of the substrate(10), since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70.
Regarding claims 7 and 8, Wei fails to explicitly disclose wherein a recessed area is disposed on an upper surface of the interlayer insulating layer, and the thermal conduction functional layer is disposed in the recessed area (claim 7); a cross-sectional shape of the recessed area is any one of a rectangle, a trapezoid, a triangle, a rhombus, or a parallelogram (claim 8). However Wei discloses in several embodiments recesses or openings in insulation structures and depositing other layers .The recesses having a particular cross-sectional shape.
It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the display panel of Wei as disclosed by Wei, wherein a recessed area is disposed on an upper surface of the interlayer insulating layer, and the thermal conduction functional layer is disposed in the recessed area ; a cross-sectional shape of the recessed area is any one of a rectangle, a trapezoid, a triangle, a rhombus, or a parallelogram the motivation being to provide a device that can solve the problem of high temperature in electroluminescent display panels.
Regarding claim 11 and 13, the limitations wherein the thermal conduction functional layer is disposed between the color resist blocks and the encapsulation layer (claim 11);. wherein the thermal conduction functional layer is disposed on both upper surfaces and lower surfaces of the black matrices and color resist block (claim 13),. etc do not appear to contain any additional features which define more than slight constructional changes which come within the scope of the customary (design) practice followed by persons skilled in the art, especially as the advantages thus achieved can be readily contemplated in advance. Alternatively, these limitations are not deemed patentable since the applicant’s disclosure fails to show such limitations to solve any problems or to yield any unobvious advantage that is not within the scope of the teachings applied. Therefore, such limitations would be a matter of design alternative.
It would have been obvious to one of ordinary skill to modify the display panel of Wei wherein the thermal conduction functional layer is disposed between the color resist blocks and the encapsulation layer;. wherein the thermal conduction functional layer is disposed on both upper surfaces and lower surfaces of the black matrices and color resist block the motivation being preventing the problem of uneven display brightness caused by excessively high temperature of the light-emitting functional layer, and since design alternative requires only routine skill.
Claims 14-15 are rejected under 35 U.S.C. 103 as being unpatentable over Wei et al, (CN 110299469 A, machine translation 10-2019) (Wei, hereafter) in view of Li et al. (US 20220328578 A1).
Regarding claims 14 and 15, Wei discloses the display panel set forth above (see rejection claim 4). Wei further discloses a cover plate (Figure 1:2).disposed above the black matrixes (34).Wei fails to explicitly disclose wherein an optical adhesive is disposed on a surface of the black matrices facing the cover plate(claim 14); wherein the black matrices are defined with grooves, and the optical adhesive is partially filled in the grooves (claim 15).

It would have been obvious to one of ordinary skill to modify the display panel of Wei as disclosed by Li disclose wherein an optical adhesive is disposed on a surface of the black matrices facing the cover plate; wherein the black matrices are defined with grooves, and the optical adhesive is partially filled in the grooves the motivation being to provide a device that can realize higher color gamut, higher resolution and larger viewing angles.
Claims 18-19 are rejected under 35 U.S.C. 103 as being unpatentable over Wei et al, (CN 110299469 A, machine translation 10-2019) (Wei, hereafter) in view of Panchawagh et al, (US 20180373913 A1) (Panchawagh , hereafter).
Regarding claims 18-19, Wei fails to disclose wherein the OLED display panel further comprises an isolation layer, the isolation layer is an insulating material, and the isolation layer is disposed on at least one surface of the thermal conduction functional layer (claim 18) or disposed around the thermal conduction functional layer (Claim 19).
Panchawagh discloses the mechanical stress isolation layer may serve a thermal function by providing for improved heat dissipation and better temperature uniformity at the back of the display. the mechanical stress isolation layer may include a plastic material (is an insulator) and serve atop an electrical shielding layer that may serve an electrical function by providing an electrical or electromagnetic barrier or an EMI shield from other electrical components and reduce electromagnetic interference. The electrical shielding layer may serve a thermal function by providing heat dissipation and improving temperature uniformity at the back of the display(π43-π48).
One of ordinary skill in the art before the effective filing date would modify the display panel of Wei as disclosed by Panchawagh above wherein the OLED display panel further comprises an isolation layer, the isolation layer is an insulating material, and the isolation layer is disposed on at least one surface of the thermal conduction functional layer or disposed around the thermal conduction functional layer the motivation being too able to provide a system in which to provide a device protected from EMI and heat degradation.
