Claim Rejections - 35 USC § 103
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(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lim et al. (US PGPub 2021/0167144; hereinafter “Lim”) in view of Kimura et al. (US PGPub 2016/0103359; hereinafter “Kimura”).
Re claim 1: Lim teaches (e.g. fig. 6) a display apparatus comprising: a substrate (SUB as shown in fig. 6); a first light emitting device (light emitting layer EL within G as shown in fig. 6; e.g. paragraph 110; hereinafter “1LED”) and a light receiving device (light receiving layer RL within SPX as shown in fig. 6; e.g. paragraph 111; hereinafter “LRD”) disposed on the substrate (SUB) and positioned adjacent to each other (LED and LRD are adjacent to each other); and a light blocking layer (black matrix BM as light blocking layers BM_D and BM_S; e.g. paragraphs 133 and 136; hereinafter “LBL”) disposed on the first light emitting device (1LED) and the light receiving device (LRD) and including a first upper opening (opening in BD_D; hereinafter “1UO”) vertically aligned with the first light emitting device (1LED) and a sensing upper opening (opening in BD_S; hereinafter “SUO”) vertically aligned with the light receiving device (LRD), wherein the light blocking layer (LBL) comprises a black pigment (light blocking layer BM may include organic light blocking material including at least one of carbon black and/or titanium black; e.g. paragraph 133).
Lim is silent as to explicitly teaching the light blocking layer comprises a black pigment and a blue pigment.
Kimura teaches the light blocking layer (black matrix BM) comprises a black pigment (carbon pigment; e.g. paragraphs 207 and 222) and a blue pigment (10% or less of the mass ratio is an organic pigment such as blue pigment; e.g. paragraph 222).
It would have been obvious to one of ordinary skill in the art at the time of effective filing, absent unexpected results, to use the added blue pigment to the black matrix as taught by Kimura in the device of Lim in order to have the predictable result of improving the half value wavelength to be within 800nm (see paragraph 229 of Kimura).
Re claim 2: Lim in view of Kimura teaches the display apparatus of claim 1, wherein a weight ratio of the black pigment to the blue pigment is greater than about 10:0 and less than or equal to about 7:1 (the blue pigment is 10% or less; e.g. paragraph 222 of Kimura).
Re claim 3: Lim in view of Kimura teaches the display apparatus of claim 1, wherein the black pigment comprises at least one of a carbon black and an organic black pigment (carbon black; e.g. paragraph 133 of Lim and paragraph 222 of Kimura).
Re claim 4: Lim in view of Kimura teaches the display apparatus of claim 1, wherein the blue pigment (blue 15:6; e.g. paragraph 229 of Kimura) comprises at least one of C.I. pigment blues 15, 15:1, 15:2, 15:3, 15:4, and 15:6.
Re claim 5: Lim in view of Kimura teaches the display apparatus of claim 1, wherein the light blocking layer further comprises a violet pigment (violet V23; e.g. paragraph 229 of Kimura), and the violet pigment comprises at least one of C.I. pigment violets 1, 19, 23, 27, 29, 30, 32, 37, 40, 42, and 50.
Re claim 6: Lim teaches the display apparatus of claim 1, further comprising a touch sensor layer (touch conducting layers TCL1,TCL2 of touch sensing layer TSL; e.g. paragraph 59) arranged between the first light emitting device (1LED) and the light receiving device (LRD) and the light blocking layer (LBL) and comprising a plurality of touch conductive patterns (touch conducting layers TCL1,TCL2 of touch sensing layer TSL; e.g. paragraph 119) and a plurality of touch insulating layers (touch insulating layers TIL,TCNT,TPVX of touch sensing layer TSL; e.g. paragraph 119).
Re claim 7: Lim teaches the display apparatus of claim 6, wherein a lower surface of the light blocking layer (LBL) contacts a layer comprising an inorganic material (TPVX is an inorganic film; e.g. paragraph 127 of Lim).
Re claim 8: Lim teaches the display apparatus of claim 7, wherein the lower surface of the light blocking layer (LBL) contacts a touch insulating layer (TPVX is an inorganic film; e.g. paragraph 127 of Lim) included in the touch sensor layer (TSL).
Re claim 9: Lim teaches the display apparatus of claim 6, further comprising an encapsulation layer (encapsulation layer TFEL; e.g. paragraph 64, 65) arranged between the first light emitting device (LED) and the touch sensor layer (TSL) and comprising at least one inorganic layer and at least one organic layer (one inorganic layer and one organic layer; e.g. paragraph 64 and 65).
Re claim 10: Lim teaches the display apparatus of claim 1, further comprising: a first color filter (color filter CF_D; e.g. paragraph 140) in the first upper opening (1UO); and a sensing color filter (color filter CF_S; e.g. paragraph 140) in the sensing upper opening (SUO).
Re claim 11: Lim teaches the display apparatus of claim 10, wherein the first color filter (CF_D) and the sensing color filter (CF_S) transmit light in a same wavelength band (CF_D may be a green filter; e.g. paragraph 141; CF_S may be formed of a green color filter; e.g. paragraph 143).
