Claims 1-10, 13, 15, 16, 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over YI SHEN CN101477430A (English machine translation) in view of ZHANG LEI (CN113867570A) (English machine translation).
Regarding claims 1, 20, YI SHEN CN101477430A discloses a capacitive touch screen and specifically discloses (4-6 of the specification, Fig. 2) that the transparent electrode conductive layer 12 is composed of a plurality of electrodes (including six sensing electrodes 121, six lead electrodes 122 and filling electrodes 123). Such capacitive touch screens can be used for single touch operation. In addition, the number of sense electrodes 121 and lead electrodes 122 may be provided according to practical needs, with the sense electrodes 121 and lead electrodes 122 being the same number and connected in one-to-one correspondence. Sense electrodes 121 are electrodes (equivalent to touch detection electrodes) that generate a sense capacitance when touch screen is touched, each sense electrode 121 is not conductive to each other and there is a void region between them; the lead electrodes 122 are transparent wires (equivalent to touch detection leads) connecting the sense electrodes 121 with external circuitry, one sense electrode 121 per lead electrode 122. The filling electrode 123 is distributed between the sensing electrodes 121 and the interstitial area (equivalent to the first gap) between the sensing electrodes 121 and the lead electrodes 122 and is not in communication with the sensing electrodes 121 and the lead electrodes 122, and its role is to eliminate the sensing electrodes 121 and lead electrodes 122 which create electrode shadows on the transparent insulating layer 11. The sense electrode 121 is within the viewable area 14 of the capacitive touch screen, and the fill electrode 123 and the lead electrode 122 are present both within the viewable area 14 and within the non-viewable area 15 (i.e. The area outside the viewable area 14). Within the viewable area 14 of the capacitive touch screen, the edges of each electrode (including the sense electrode 121, the lead electrode 122, and the filling electrode 123) on the transparent electrode conductive layer 12 are jagged (the outline corresponding to the first gap includes at least two first curves connected in sequence). Since the edge of each electrode is serrated, the orientation of the edges of the electrodes with the smaller linewidth of the capacitive touch screen (e.g., the filler electrodes 123, the lead electrodes 122) and the gaps 126 between the electrodes is slanted at an angle to the alignment of the pixel dot array of the dot array display device (equivalent to the display panel), thus, in terms of interference of light, it is equivalent to changing the direction of the slit so that the resulting interference fringes are not noticeable or disappear, effectively reducing or avoiding interference phenomena of the light from the touch surface viewable area 14. In addition, it is straightforward and unambiguously ascertained from the following description of Fig. 2, that the display panel has the display region 14 and the peripheral region 15 provided at the periphery of the display region, and that the touch sensing lead 122 is provided on the side of the touch sensing electrode 121 close to the peripheral region 15 and at least partially inside the display region 14. YI SHEN CN101477430A a gap between an orthographic projection of the touch detection leads 122 onto the substrate substrate and an orthographic projection of the touch detection electrodes 121 onto the substrate. The solution claimed in this claim is distinguished by the technical feature that the touch sensing electrode and the touch sensing lead of the present application are formed by grid-shaped conductive sections provided on one side of the substrate and positioned in the display region as compared to the technical content disclosed in this comparative document. Based on the above distinguishing technical features, the technical problem actually solved by claim 1 lies in how to design an alternative structure of touch sensing electrodes and touch sensing leads.
ZHANG LEI (CN113867570A) discloses a touch substrate and a touch display panel, and specifically discloses (see specification paragraphs 0061-0070, Figures 7-9) that a touch electrode layer includes a plurality of first electrodes arranged in parallel, a plurality of second electrodes arranged in parallel (equivalent to touch sensing electrodes), a plurality of first signal lines and a plurality of second signal lines (equivalent to touch sensing leads). In an embodiment of the present disclosure, since the first electrode, the second electrode are divided out of the conductive grid structure (or the first sub-grid structure and the second sub-grid structure it comprises) (equivalent to a grid-like conductive part), the areas where the remaining mesh structures are still present at the gaps of the first electrode, the second electrode, the first signal line and the second signal line can be seen as dummy regions. As shown in Figures 3 and 6 to 10, the first electrode 110 (of which Figure 7 shows three first electrodes 110a, 110b, 110c) is divided by the first sub-grid structure 101. Furthermore, the second signal line 140 is divided by the first sub-grid structure 101 (of which two second signal lines 140a, 140b are shown in Figure7). ZHANG LEI (CN113867570A) discloses that a touch sensing electrode and a touch sensing lead can be divided by a conductive grid, and serves the same role in ZHANG LEI (CN113867570A) as it serves in this claim, for forming a touch sensing electrode and a lead using a conductive grid.

In this way, the meshes of the first sub-grid structure 101 and the second sub-grid structure 102 are divided into small meshes by each other's mesh lines. As shown in FIG. 3 , the meshes of the first sub-grid structure 101 are divided into four small meshes by the grid lines of the second sub-grid structure 102 . Similarly, the meshes of the second sub-grid structure 102 The grid lines of the first sub-grid structure 101 are also divided into four small mesh holes, and the divided small mesh holes are the mesh holes of the conductive mesh structure).
