New Description: [New Technology Field] This is a projection capacitive touch device, especially a projected capacitive touch panel that can simplify the process by changing the spatial pattern of the electrode string. . [Prior Art] At present, the touch device is a technology widely praised by users in the market. Among them, the projected capacitive touch device supporting multi-touch is most favored by users, and therefore most manufacturers will use projected capacitors. The touch device is set up in many digital products as a manipulation interface. Referring to FIG. 3, the known projected capacitive touch panel is mainly provided on a transparent substrate 40 with X-axis sensing electrode strings 5 〇 and γ-axis sensing electrode strings 60 interlaced with each other, and each Y-axis sensing electrode string 6 The 〇 includes a plurality of γ-axis electrodes 61 and wires 62 connecting the two adjacent Y-axis electrodes; each of the 感应-axis sensing electrode strings 50 includes a plurality of X-axis electrodes 51 and a bridging wire 52, since the shaft electrode 61 and the X-axis electrode 51 are attached to each other. The matrix is arranged such that its wire μ is overlapped with the bridge wire 52, and in order to ensure the normal operation of the έ|έ sensing electrode string 5〇 and the Υ-axis sensing electrode string 60, the wire 62 between adjacent γ-axis electrodes 61 is adjacent to each other. An insulating layer 7 is disposed between the bridging wires 52 of the X-axis electrode 51 to be isolated from each other. In terms of process, the first step is to first cover the transparent substrate 40 with a |T 〇 transparent electrode, which is formed by the surname to form the y-axis electrode ^ and its wire 62', and then an insulating step is formed on each of the wires 61. The layer 70 is then overlaid with a transparent electrode to form a % axis 3 M420775 electrode 51 and a cross-bridge wire 52' wherein the bridge wire 52 is above the insulating layer 70 and utilizes the insulating layer 70 and below The wires 61 are isolated from each other. It can be seen from the above that one of the processes of the projected capacitive touch panel forms a x-axis electrode string and a Y-axis electrode string on one side of the single transparent panel, and the X and Y axis electrodes are arranged in a matrix, adjacent to the x-axis. The cross-bridge wire between the electrodes and the adjacent Y-axis electrode will inevitably intersect, so insulation isolation must be performed, but the insulation isolation process will increase the process steps, so how to maintain the function of the projected capacitive touch panel is not Change, but can effectively simplify the process, that is, to further seek a feasible solution. [New content] In view of the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to provide a type of projected capacitive touch panel, which is mainly for making a plurality of first-inductive electrode strings and second sensing electrode strings on a transparent substrate parallel and Arranged between the phases, the electrodes are still in the matrix (4) but there is no staggered line, thereby achieving the purpose of process steps and cost reduction. The technical means for achieving the above object is that the projected capacitive touch panel comprises: a transparent substrate having a surface; a plurality of first sensing electrode strings, forming a v-% on the transparent substrate and arranged in parallel Each of the first sensing electrode strings includes a plurality of first electrodes and a first wire connecting the two adjacent first electrodes; a plurality of second sensing electrode strings are formed on the transparent substrate, each of which is formed on each of the transparent substrates The first sensing electrode strings are arranged in parallel with each other; each of the first sensing electrode strings of each of the first sensing electrode strings comprises three silver-based second electrodes and a second wire connecting M420775 to two adjacent second electrodes. The first sensing electrode string and the second sensing electrode string are arranged on the surface i of the transparent substrate, and the two capacitances through the first and second electrodes are calculated to define the finger on the touch panel. The position pointed to. - Since the first sensing electrode contends with the second sensing electrode string, there is no wire interlacing, and the first sensing can be formed in the process. The electrode string and the first: sensing electrode string eliminate the steps of forming an insulating layer and forming another electrode string on the insulating layer, thereby shortening the process steps and reducing the cost. [Embodiment] A preferred embodiment of the present invention Referring to FIG. 1 and FIG. 2, the method includes: a transparent substrate 10 having a surface; a plurality of first sensing electrode strings 20 formed on the surface of the transparent substrate 1 且 and arranged in parallel, each of the first sensing electrodes The string 20 includes a plurality of first electrodes 21 and a plurality of first conductive electrode strings 30 connecting the two adjacent first electrodes 21, and is formed on the transparent panel 1 ,, and each of the second sensing electrode strings 30 is parallel to each other. Each of the second sensing electrode strings 30 includes a plurality of first electrodes 31 and a second wire 32 connecting the two adjacent second electrodes 31. The above transparent substrate is implemented in the present embodiment. In the example, the transparent substrate 1 is coated with a transparent electrode layer on the surface, and is etched to simultaneously form the first sensing electrode string 20 and the second sensing electrode string 30, and the transparent substrate 10 5 M4 20775 surface in which __ connecting line 11, 1 or both ends are formed with multiple connecting lines
