The metal guides 15a, 15b are disposed at the edge of the base substrate 1 and are connected to a signal wheel terminal (not shown), whereby the χ axis trace ΐ 2 ι and the Υ axis trace 122 on the sensing layer 12 are The sensing signal can be transmitted to a subsequent signal processing circuit via the signal output terminal; the barrier layer 13 has a plurality of insulating masks using a polyester film material having a high light transmittance and a dielectric constant of about 3 and a thickness of about Uym. And the covering area of the insulating mask is at least sufficient to cover the X-axis trace portion 12ib between the two adjacent array sensing units 122a on the γ-axis trace; the jumper conductive layer 14 has a complex edge An electric wire disposed in the Y-axis direction, wherein the electric wire is an opaque metal conductor having a wire diameter smaller than U/zm, and an electrical connection portion 141 having a larger contact area than the electric wire body at the two end edges of the electric wire, and The electric wire is set The upper surface of the insulating mask of the barrier layer 13 is disposed, and the electrical connection portion 141 of the two ends of the electrical conductor is extended outside the insulating mask; the capacitive sensing layer 12, the barrier layer 13 and the flea conductive layer M359752 14 When combined, the insulating masks of the resistive layers 13 are disposed between an adjacent array of sensing elements 122a corresponding to the gamma axis traces, and the X-axis trace portions 121b between the two adjacent array sensing units are passed. The insulating cover is provided, and the electrical junctions 141 of the two ends of the electrical leads of the jumper conductive layer 14 are respectively electrically connected to the two adjacent sensing units 122a on the γ-axis trace so as to be on the individual γ-axis traces 122. Each of the sensing units is electrically connected to each other to form a capacitive sensing structure. In addition, in the present embodiment, the X-axis sensing unit i21a and the Y-axis sensing unit 122a on the s-capacitance sensing layer 12 are further provided with imitation lines 129, and the imitation lines 129 are respectively The edges of the X-axis sensing unit 12ia and the γ-axis sensing unit 122a are kept at an interval 1293 without being connected. The usual interval 129a is about 20/m to 50//m, and ideally, the imitation line 129 is The X-axis sensing unit 121a and the Y-axis sensing unit 122a have the same material, that is, a transparent conductive film made of indium tin oxide, so that the capacitive sensing layer 12 has a relatively uniform light transmittance. According to the capacitive sensing structure formed by the above description, an equivalent capacitance can be formed between the X-axis trace 121 and the golden-pointed guide 15a, and there is an equivalent between the γ-axis trace m and the metal guide 15b.

And the transmittance uniformity of the touch panel improves the lack of development blur distortion; further, the setting means of the imitation texture 129 can expand X without increasing the hollow portion _ on the capacitor layer 12 The setting between the base unit and the γ-axis sensing unit is for the purpose of reducing the value of the capacitor; and as described above, the imitation line 129 and the X-axis and γ-axis sensing unit 121a 122a τξ: The same material is formed on the same capacitive sensing layer 12, so that the setting can be completed simultaneously in the capacitive sensing layer 12, so that the process or production cost is not additionally increased. For example, in the fourth embodiment of the present invention, the capacitive sensing structure of the touch panel is slightly different from the first-the real-off, that is, it includes the base substrate 4 and the upper panel 5, in the second A capacitive sensing layer 42 is disposed between the boards, and the two boards are laminated and bonded into a board by a glue layer 6; the main difference from the foregoing first embodiment is the setting of the capacitive sensing layer 42, wherein The capacitive sensing layer 42 is disposed on the upper surface of the base substrate*, and the capacitive sensing layer 42 is a transparent conductive film of indium tin oxide material f, and has three sensing units 42& The sensing units must be arranged in a staggered arrangement with each other at equal intervals (see the fourth figure), and then the -end edges of the respective sensing singles 42a are respectively electrically connected to the gold flexures provided at the edge of the base substrate 4. The circuit 42b' is connected to a signal output terminal (not shown), whereby the sensing signal of each sensing unit 42a can be transmitted to the subsequent processing circuit 8 M359752 through the signal output terminal; The setting gap of the unit 42a is also filled with the imitation texture 49, and the The imitation lines 49 are respectively connected to the edges of the two adjacent sensing units 42a by a gap 49a, and the spacing 49a is usually about 20//m~50#m'. In the ideal, the imitation lines are 49 is a transparent conductive film having the same material as the sensing unit 42a, that is, indium tin oxide, so that the capacitive sensing layer 42 has a relatively uniform light transmittance, thereby improving the flatness of the appearance and the touch panel. The uniformity of light transmittance improves the lack of development blur distortion. Reuben's creation is not limited to the above-mentioned forms. It is obvious that with reference to the above description, there can be more improvements and changes in technical equivalence, for example, when the imitation texture is applied to a conventional capacitive sensing structure, The X-axis trace and the χ-axis trace are separated on two different capacitive sensing layers, and are separated by an insulating layer between the two capacitive sensing layers, so the imitation texture is optionally The peripheral portion of the sensing unit disposed on any of the axis line traces or the Υ axis traces may be disposed on the insulating layer to correspond to the joint portion of the gap between the χ-axis sensing unit and the γ-axis sensing unit. And such change settings can achieve the same or similar performance as the previous embodiments, and therefore should be substantially the same as the prior art of this creation. Therefore, any modification or alteration of the creation made in the same creative spirit should still be included in the protection of this intention.
