The embodiment chatted after being not limited to.By the electrode institute of the self-capacitance type touch panel for increasing resistance value using tortuous line segment of the present invention
Comprising material and preparation method may be, it is known that therefore not influenceing the abundant disclosure of the electrode design pattern and exploitativeness
On the premise of, illustrate that for known details memorandum will be given below.
Fig. 2A is referred to, it is an embodiment of the equivalent resistance of the electrode of the increase self-capacitance type touch panel of the present invention
Schematic diagram.Electrode 210 and electrode 211 shown in figure are paired electrode, similar to the paired electrode 110 and 111 in Fig. 1.Electricity
Pole 210 includes the part for not being fabricated to tortuous line segment (or be snake line, Serpentine trace), hereinafter referred to as principal part
210A, and the zigzag part 210B of a tortuous line segment is included, electrode 211 includes principal part 211A, and zigzag part 211B.Zigzag part
210B is connected to the control circuit (not illustrating) of contact panel via wire 212, and zigzag part 211B is connected to tactile via wire 213
Control the control circuit of panel.Electrode 210 is approximate with one of its principal part 210A and zigzag part 210B shape, and electrode 211
It is approximate with one of its principal part 211A and zigzag part 211B shape.Below will by compare paired electrode 210 and 211 with into
How the zigzag part of the present invention, which increases the surface resistance of electrode, is illustrated to electrode 110 and 111.
The area of paired electrode 110 and 111 is substantially equal, and shape is generally triangular or subtriangular, triangle
E.g. right angled triangle or other kinds of triangle, the acute angle portion of subtriangular such as triangle is by an extremely short side
Substitution, as shown in figure 3, it is the enlarged drawing of Fig. 1 paired electrode 110 and 111, the length of the short side is x, when electrode 110 and
When the height h of electrode 111 is much larger than short side long x, the shape of electrode 110 and electrode 111 is just closer to triangle.Electrode 110 and
The surface resistance of electrode 111 can be obtained by following calculation：
Wherein R□For the resistance matter of material used in electrode.In a preferred embodiment, h=51mm, x=
0.3mm, y=1.23mm, therefore it is about 77.37R that can obtain the surface resistance of electrode 110 or electrode 111 by above-mentioned calculation□。
And Fig. 2A electrode 210 and the calculation of surface resistance of electrode 211 are classified into two parts calculating, that is, principal part is first calculated respectively
210A (211A) surface resistance and zigzag part 210B (211B) surface resistance, then be added to obtain total face of electrode 210 (211) electricity
Resistance.By taking electrode 210 as an example, principal part 210A surface resistance isAnd calculate zigzag part 210B's
Fig. 2 B are referred to during surface resistance, zigzag part 210B is divided into 5 sub- line segments, respectively sub-line section 201B-1~201B-5, sub-line
Section 201B-1 width is h0B1, and the line width between sub-line section 201B-1 and sub-line section 201B-3 is h0B2(that is, sub-line section
201B-2 width), the rest may be inferred by analogy for it, and the length of each sub-line section is respectively y1~y5.Each sub-line section is near with the rectangle shown in dotted line
Like it, and the calculation of the surface resistance of rectangle is：
Therefore zigzag part 210B surface resistance is：
(y1/h0B1+y2/h0B2+y3/h0B3+y4/h0B4+y5/h0B5)R□。
In a preferred embodiment, sub-line section 210B-1, sub-line section 210B-3, sub-line section 210B-5 are parallel to each other,
And there is identical line width and spacing, that is to say, that h0B1=h0B2=h0B3=h0B4=h0B5=h '.As principal part 210A in Fig. 2A
Height h0AFor 49.0mm, width y0For 1.2025mm, then principal part 210A surface resistance is about R210A=75.38R□, and it is tortuous
Portion 210B resistance is (assuming that all equal the h '=0.3mm of line width and spacing, and by sub-line section 210B-2 and sub-line section 210B-4
It is approximately square) R210B=(1.23/0.3+1+1.210/0.3+1+1.208/0.3) R□, it is approximately equal to 14.19R□.Therefore electricity
Total surface resistance value of pole 210 is about 75.38R□+14.19R□=89.57R□, more than the surface resistance of the electrode 110 shown in Fig. 3.Please
Pay attention to, Fig. 2A also includes connection principal part 210A and zigzag part 210B connecting portion 210C, and connection principal part 211A and zigzag part
211B connecting portion 211C.If connecting portion 210C surface resistance is included into calculating (also assuming that as square), electrode 210
Surface resistance value is about 90.57R□.In various embodiments, connecting portion 210C (211C) can be principal part 210A (211A) or song
Folding part 210B (211B) part.In addition, the mode of zigzag part 210B division sub-line sections is also not necessarily limited to Fig. 2 B mode, also may be used
Mode as that shown in fig. 2 c, the surface resistance of each sub-line section are different from the surface resistance for the sub-line section that Fig. 2 B are presented, but total surface resistance
It is identical.
From the foregoing, the surface resistance of electrode can be increased by a part for electrode is fabricated into tortuous line segment, and
And surface resistance can be changed by the number for the sub-line section for adjusting tortuous line segment, same area splits into the sub-line of tortuous line segment
The more, the surface resistance of electrode is also just bigger for section, that is to say, that the length of all sub-line sections, which adds up, more to be grown, and the electrode pair should control
The equivalent resistance of circuit 130 is just bigger.Because the electric capacity in the surface resistance and self-capacitance type touch panel of electrode forms low pass filtered
Ripple device, in more detail, two electrodes of the electric capacity in self-capacitance type touch panel are respectively by electrode and substrate the institute structure of contact panel
It is in general ground connection into, substrate, therefore can be by the surface resistance of adjustment individual electrode by corresponding low pass filter
Cut-off frequency designs the frequency range in needs.Such as when Fig. 1 control circuit 130 charges to the electric capacity of self-capacitance type touch panel,
Easily there is surging, and cause circuit unstable.Referring to Fig. 8, it is the charging-discharging cycle of known self-capacitance type touch panel
Schematic diagram.As illustrated, having a surging when charging indicated at dotted line frame choosing, surging is the signal of high frequency, therefore can be with
Filtered out using above-mentioned low pass filter.In the case of electric capacity is identical, it be able to should be controlled by each electrode pair is adjusted
The equivalent resistance of circuit, make the cut-off frequency of low pass filter corresponding to each electrode in the band limits of surging, effectively to filter
Except surging.
