Fig. 5 is the schematic diagram of the contact panel of the fourth embodiment of the present invention.Please refer to Fig. 5, in the present embodiment, the contact panel 100a of contact panel 100c and aforesaid second embodiment is similar, and its Main Differences is, part first electrode 120a to the first electrode 120d of contact panel 100c has at least one slit pattern 124a or slit pattern 124b separately.Specifically, contact panel 100c has the composition of similar contact panel 100a, and its similar component represents with identical label, and has similar function.When the first wire 140 correspondence is configured in channel C 1 to the channel C 3 formed by spacing G4 to spacing G9, between the first wire 140 of strip, be separated by a distance and the visual effect that formed as slit (slit).Now, will there be significant vision difference in the region being provided with the first wire 140 and the region not being provided with the first wire 140.Therefore, the present embodiment is taked to configure slit pattern 124a or slit pattern 124b on the first electrode 120a to the first electrode 120d, wherein slit pattern 124a is positioned on the first electrode 120a to the first electrode 120c and corresponds to multiple strip openings of the second electrode 130a to the second electrode 130c, and slit pattern 124b is the multiple strip shaped electric poles being positioned at spacing.
In the present embodiment, each slit pattern 124a and slit pattern 124b be positioned at the second electrode 130a to the second electrode 130c one of them, be such as the second all electrode 130a to the second electrode 130c, in the frontal projected area on first substrate 110.Slit pattern 124a does not block the first electrode 120a and the sub-electrode 122 of its correspondence, therefore slit pattern 124a does not affect the first electrode 120a of correspondence and electrically conducting of sub-electrode 122, and slit pattern 124b does not contact the first electrode 120a, sub-electrode 122 and the first wire 140, therefore slit pattern 124b does not affect the electrical independence of each component in contact panel 100b.It can thus be appreciated that, slit pattern 124a can make spacing G4 to the spacing G9 part in the first electrode 120a to the first electrode 120c without corresponding second electrode 130a to the second electrode 130c have to be similar to configure in spacing G4 to G9 the visual effect as slit that the first wire 140 is formed, and slit pattern 124b can fill up in spacing the region not being configured with the first wire 140, to improve the visual effect of contact panel 100c.Similarly, first electrode 120a to the first electrode 120d of the contact panel 100c of the present embodiment and the relative position of the second electrode 130a to the second electrode 130c and configuration relation can with reference to the aforementioned descriptions corresponding to Fig. 2 B and Fig. 2 C, and the overlay 102 that contact panel 100c uses can, according to demand configuration decorative layer as shown in Figure 2 D, not added to repeat at this yet.
Fig. 6 is the schematic diagram of the contact panel of the fifth embodiment of the present invention.Please refer to Fig. 6, in the present embodiment, contact panel 200 comprises first substrate 210, first electrode 220a to the first electrode 220d, the second electrode 230a to the second electrode 230d, many first wires 240 and many second wires 250.First electrode 220a to the first electrode 220d is separately along first direction D1 extension and along second direction D2 sequential, and the second electrode 230a to the second electrode 230d is separately along second direction D2 extension and along first direction D1 sequential.First electrode 220a to the first electrode 220d is connected to the first wire 240, and the second electrode 230a to the second electrode 230d is connected to the second wire 250.Meanwhile, first substrate 210 is used for carrying first electrode 220a to the first electrode 220d, the second electrode 230a to the second electrode 230d, many first wires 240 and many at least one parts of second these components of wire 250, and provides user to touch.
In order to realize the design on narrow limit and reduce the border width of contact panel 200, in the present embodiment, one end of part first electrode 220b to the first electrode 220d has and inside contracts district R1 to inside contracting district R3.Inside contract district R1 and be overlapped in outermost second electrode 230a to inside contracting district R3, the first wire 240 is arranged in and inside contracts district R1 to inside contracting district R3.Specifically, in the present embodiment, the first electrode 220a to the first electrode 220d is more less close to abutting end width in the first direction dl.In other words, the first electrode 220a to the first electrode 220d width in the first direction dl sequentially successively decreases along second direction D2, can define respectively inside contract district R1 to inside contracting district R3 with the side of the first electrode 220b to the first electrode 220d making part.In other embodiments, the first electrode 220a also selectively can have and inside contracts district.Also namely, the first electrode 220a is maximum at the width of first direction D1, and the first electrode 220d is minimum at the width of first direction D1.Because the width of first electrode 220a to the first electrode 220d of the present embodiment sequentially successively decreases, therefore the district R1 that inside contracts of corresponding different first electrode 220b to the first electrode 220d sequentially increases progressively to inside contracting district R3 width w3 in the first direction dl to width w5.Inside contract district R1 and be overlapped in the second electrode 230a to inside contracting district R3, and respectively inside contract district R1 and be less than the second electrode 230a width in the first direction dl corresponding to it to inside contracting district R3 width w3 in the first direction dl to width w5.Now, the district R1 that inside contracts being overlapped in same second electrode 230a forms passage to inside contracting district R3, and the first wire 240 is arranged in and inside contracts district R1 to the passage inside contracting district R3 and formed.So, the first wire 240 is positioned at the frontal projected area of the second electrode 230 on first substrate 210, and is extended towards abutting end 212 by the first connected electrode 220a to the first electrode 220d.
In the present embodiment, due to the present embodiment the first electrode 220b to the first electrode 220d inside contract district R1 to the one end inside contracting district R3 and be positioned at the first electrode 220b to the first electrode 220d, and inside contract district R1 and inside contract district R1 and be all positioned at second electrode 230a frontal projected area on first substrate 210 to the first wire 240 inside contracting district R3 to inside contracting district R3 and being arranged in and be positioned at the side of first substrate 210, therefore compared to aforesaid first embodiment to the 4th embodiment, the present embodiment does not need part first electrode 220a to the first electrode 220d to cut into multiple sub-electrode, and the first electrode 220b to the first electrode 220d can be made with the electrode pattern of continuous one.Moreover what the first wire 240 is configured in the first electrode 220b to the first electrode 220d inside contracts district R1 to inside contracting in district R3, the frame of first substrate 210 does not need the reserved space arranging the first wire 240.Accordingly, the border width of contact panel 200 can be reduced, reach the design on narrow limit.
In addition, in the present embodiment, the second electrode 230b to the second electrode 230d is strip shaped electric poles, but has the body 232 of strip and multiple compensation section 234 outstanding from body 232 side corresponding to inside contracting district R1 to the second electrode 230a inside contracting district R3.Specifically, the first electrode 220b to the first electrode 220d due to the present embodiment has and inside contracts district R1 to inside contracting district R3, and inside contract district R1 and sequentially increase progressively to width w5 to inside contracting district R3 width w3 in the first direction dl, the overlapping area of the therefore orthogonal projection of body 232 on first substrate 210 of the first electrode 220b to the first electrode 220d and strip is sequentially successively decreased.So, each first electrode 220a to the first electrode 220d can be made not identical with the initial capacitance value between the second electrode 230a.Therefore, the second electrode 230a is configured to have multiple compensation section 234 by the present embodiment.Compensation section 234 is given prominence to from body 232 along first direction D1 towards the second adjacent electrode 230b and is corresponded respectively to and inside contracts district R1 to inside contracting district R3, and the area of the orthogonal projection of each compensation section 234 on first substrate 210 can be set to equal inside contract district R1 to the area inside contracting the orthogonal projection of district R3 on first substrate 210 corresponding to each compensation section 234, therefore the area of the compensation section 234 of the present embodiment is also sequentially change along second direction.So, by the design of compensation section 234, the first electrode 220a to the first electrode 220d can be made to be overlapped in the overlapping area of the second orthogonal projection of electrode 230a on first substrate 210 equal, to reduce the capacitance difference between each first electrode 220a to the first electrode 220d and the second electrode 230a.
Fig. 7 is the partial schematic diagram of the contact panel of Fig. 6.Fig. 8 is the changing trend diagram of the capacitance of the contact panel of Fig. 7.Please refer to Fig. 6 to Fig. 8, in the present embodiment, using the region A1 in Fig. 7 to region A3 as simulation, wherein region A1 to region A3 is respectively the first electrode 220a to the first electrode 220c is overlapped in the second orthogonal projection of electrode 230a on first substrate 210 overlapping region when not having compensation section 234.Inside contract district because the first electrode 220a does not have, and inside contracting district R1 and inside contracting district R2 of the first electrode 220b and the first electrode 220c sequentially increases progressively, therefore the area of the region A1 of the present embodiment to region A3 sequentially successively decreases.Whether the capacitance between the first electrode 220a to the first electrode 220c corresponding to comparison domain A1 to region A3 and the second electrode 230a and capacitance difference value have the result of compensation section 234 as following table relative to the second electrode 230a:
Table one: capacitance comparison sheet
Region Not there is compensation section There is compensation section
A1 1.1538 1.1702
A2 0.7532 0.9132
A3 0.5423 0.8087
Table two: capacitance difference value comparison sheet
Region Not there is compensation section There is compensation section
A1-A2 0.4006（34.72%） 0.257（21.90%）
A1-A3 0.6115（53.00%） 0.3615（31%）
It can thus be appreciated that, when the second electrode 230a does not configure compensation section 234, capacitance between the first electrode 220a corresponding to the A1 of region and the second electrode 230a is about 1.1538 picofarad (picofarad, be called for short pF), capacitance between the first electrode 220b corresponding to the A2 of region and the second electrode 230a is about 0.7532 picofarad, and the capacitance between the first electrode 220c corresponding to the A3 of region and the second electrode 230a is about 0.5423 picofarad, its trend as shown in Figure 8.
Relatively, when the second electrode 230a configures compensation section 234, overlapping region between first electrode 220a and the second electrode 230a is maintained region A1, but the overlapping region between the first electrode 220b and the second electrode 230a becomes region A2 and the compensation section corresponding to it 234, and the overlapping region between the first electrode 220c and the second electrode 230a becomes region A3 and the compensation section corresponding to it 234.Now, capacitance between the first electrode 220a corresponding to the A1 of region and the second electrode 230a is about 1.1702 picofarads, capacitance between region A2 and the first electrode 220b corresponding to the compensation section corresponding to it 234 and the second electrode 230a is about 0.9132 picofarad, and the capacitance between region A3 and the first electrode 220c corresponding to the compensation section corresponding to it 234 and the second electrode 230a is about 0.8087 picofarad, its trend as shown in Figure 8.Therefore, by the design of compensation section, the difference of the capacitance between the first electrode 220a to the first electrode 220c and the second electrode 230a can be made to reduce.Moreover, above-mentioned comparative result be set to allow the second electrode 230a be overlapped in compensation section 234 overlapping area of the first electrode 220a to the first electrode 220c is roughly equal is described.In other embodiments, suitably the area of adjustment compensation section 234, can make the capacitance between the first electrode 220a to the first electrode 220c and the second electrode 230a more close.Accordingly, by configuring compensation section 234 corresponding to inside contracting district R1 to inside contracting district R3 and being positioned on the outermost second electrode 230a of first substrate 210, the sensing effect at the edge of contact panel 200 can be improved.In addition, first electrode 220a to the first electrode 220d of the contact panel 200 of the present embodiment and the relative position of the second electrode 230a to the second electrode 230d and configuration relation can with reference to the first electrode 120a to the first electrode 120d in aforesaid Fig. 2 B and Fig. 2 C and the second electrode 130a to the second electrode 130c, and after contact panel 200 adopts overlay 102 as shown in figs. 2 b and 2 c, overlay 102 can, according to demand configuration decorative layer as shown in Figure 2 D, not added to repeat at this yet.
