PNG media_image1.png 830 874 media_image1.png Greyscale Claim 18, Lin discloses (see annotated Fig. 1 above and Fig. 2) the display device according to claim 11, wherein the light-shielding function layer (BM) comprises a plurality of light holes (BM has holes V1/V2 as seen in Fig. 2, Para [0026]), and an orthographic projection of each of the plurality of light filter units on the light-shielding function layer cover respective one of the plurality of light holes (orthographic projection of CF1/CF2 covers V1/V2 since CF1/CF2 vertically overlaps V1/V2). 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) 10 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lin (US 2019/0206945) as applied to claims 1 and 11 above, and further in view of Xiao (US 2021/0242433). Claim 10, Lin discloses (see annotated Fig. 1 above and Fig. 2) the display panel according to claim 1, wherein the display panel further comprises a touch function layer (TP, touch structure layer, Para [0034]) disposed on a side of the pixel definition layer away from the substrate (TP is on PDL on a top side away from 100), wherein the touch function layer are covered by an orthographic projection of the light-shielding function layer (BM) on the substrate (TP is covered by an orthographic projection as seen in Fig. 1). Lin does not explicitly disclose wherein the touch function layer comprises a plurality of first touch electrodes and a plurality of second touch electrodes, and orthographic projections of the plurality of first touch electrodes and the plurality of second touch electrodes on the substrate are covered by the orthographic projection of the light-shielding function layer on the substrate. However, Xiao discloses (Fig. 18) a touch function layer 600 with a plurality of first and second touch electrodes 610 (which comprise sensing and driving touch electrodes which are not labeled), Para [0066]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for the touch function layer of Lin to have sensing and driving touch electrodes as taught in Xiao as the two types of electrodes help the device realize the touch function capability (Xiao, Para [0066]). As a result, the sensing and driving touch electrodes of Xiao may be present in Lin as the plurality of first and second touch electrodes and orthographic projections of these would be covered by the BM layer. Claim 20, Lin discloses (see annotated Fig. 1 above and Fig. 2) the display device according to claim 11, wherein the display panel further comprises a touch function layer (TP, touch structure layer, Para [0034]) disposed on a side of the pixel definition layer away from the substrate (TP is on PDL on a top side away from 100), wherein the touch function layer are covered by an orthographic projection of the light-shielding function layer (BM) on the substrate (TP is covered by an orthographic projection as seen in Fig. 1). Lin does not explicitly disclose wherein the touch function layer comprises a plurality of first touch electrodes and a plurality of second touch electrodes, and orthographic projections of the plurality of first touch electrodes and the plurality of second touch electrodes on the substrate are covered by the orthographic projection of the light-shielding function layer on the substrate. However, Xiao discloses (Fig. 18) a touch function layer 600 with a plurality of first and second touch electrodes 610 (which comprise sensing and driving touch electrodes which are not labeled), Para [0066]). Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for the touch function layer of Lin to have sensing and driving touch electrodes as taught in Xiao as the two types of electrodes help the device realize the touch function capability (Xiao, Para [0066]). As a result, the sensing and driving touch electrodes of Xiao may be present in Lin as the plurality of first and second touch electrodes and orthographic projections of these would be covered by the BM layer. Allowable Subject Matter Claims 2-7, 9, 12-17, and 19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten to overcome the 112 rejection above and in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: the closest prior art of record, Lin (US 2019/0206945), Xiao (US 2021/0242433), fail to disclose (by themselves or in combination) the following limitations in combination with the rest of the claim: Regarding Claim 2 (from which claims 3-7 depend), wherein the light-shielding function layer is disposed on a surface of a side of the transparent first pixel definition layer away from the substrate, and an orthographic projection of the transparent first pixel definition layer on each of the plurality of first electrode units covers an edge part corresponding to the first electrode unit. Regarding Claim 9, wherein the plurality of light filter units comprise a red light filter unit, a blue light filter unit, and a green light filter unit, and a transmittance of each of the plurality of light filter units for light with a color corresponding to the light filter unit is larger than or equal to 43%. Regarding Claim 12 (from which claims 13-17 depend), wherein the light-shielding function layer is disposed on a surface of a side of the transparent first pixel definition layer away from the substrate, and an orthographic projection of the transparent first pixel definition layer on each of the plurality of first electrode units covers an edge part corresponding to the first electrode unit. Regarding Claim 19, wherein the plurality of light filter units comprise a red light filter unit, a blue light filter unit, and a green light filter unit, and a transmittance of each of the plurality of light filter units for light with a color corresponding to the light filter unit is larger than or equal to 43%.
