The described contact panel 100,400,700,800 of above embodiment and 900 all is provided with detection zone in the end of each sensing axes respectively.And these detection zones are insulated layer and come out.Therefore, contact panel 100,400,700,800 and 900 can adopt easy detection mode to inspect each sensing axes or each transmission line respectively whether defectiveness produces.Specifically, contact panel 100,400,700,800 and 900 detection methods that can adopt are as follows.Figure 12 is first kind of detection method of the contact panel of one embodiment of the invention.Please refer to Figure 12, carry out step 10 earlier, a contact panel is provided.In the detection method of present embodiment, contact panel for example be in aforesaid contact panel 100,400,700,800 and 900 wherein one or contact panel 100,400,700,800 and 900 in each sensing axes only have an end to be provided with the design of detection zone.
Then, carry out step 20, by in the contact panel wherein first detection zone of one first sensing axes and wherein second detection zone of one second sensing axes detect.Specifically, the step of detection for example is to utilize one group of probe to contact first detection zone of one first sensing axes wherein and second detection zone of one second sensing axes wherein respectively.And, measure the capacitance between this group probe.Judge according to measured capacitance whether first sensing axes and second sensing axes have short circuit or the defective that opens circuit.
In addition, because of fabrication error makes the pattern of first sensing axes or the pattern of second sensing axes inconsistent, for example the area discrepancy of pattern is excessive or the spacing of pattern is inconsistent, can cause first sensing axes and the capacitance coupling effect of second sensing axes on diverse location to change thereupon.So, contact panel will the true situation of thoughts indeterminacy.Whether the pattern that present embodiment can be judged sensing axes according to the capacitance variation between different sensing axes defectiveness, with further at defect part education mend and promote the sensing accuracy of contact panel.
The detection method collocation contact panel 100,400,700,800 of present embodiment and 900 topological design can directly detect the not capacitance between the same feeling side shaft line.Such detection method can not be subjected to the influence of transmission line and more directly check out whether defectiveness of sensing axes.That is to say that the defective in the sensing axes can correctly and efficiently be detected.
Figure 13 is second kind of detection method of the contact panel of one embodiment of the invention.Please refer to Figure 13, the contact panel detection method of present embodiment for example is carry out step 10, and a contact panel is provided.At this, contact panel for example is in aforesaid contact panel 100,400,700,800 and 900 wherein one.What deserves to be mentioned is that in the contact panel that the detection method of employing present embodiment detects, all sensing axes two ends all are provided with detection zone respectively.
Then, carry out step 30, the detection zone by same sensing axes two ends detects.Can detect the resistance value of same sensing axes by the detection zone at same sensing axes two ends, whether short circuit or the defective that opens circuit be arranged to confirm each sensing axes.And the transfer impedance of sensing axes is if there is excessive difference also can detect by step 30.
For instance, when this method was applied to contact panel 100, probe can contact first detection zone 150 at same first sensing axes 120 two ends simultaneously to detect.Certainly, probe also can contact second detection zone 160 at same second sensing axes 130 two ends simultaneously to detect.In such testing process, if there is the wherein resistance value generation of a sensing axes can very correctly be judged out and carry out the patch work of correspondence unusually.Therefore, such detection method helps to promote the quality of contact panel.
Aforementioned two kinds of detection methods can detect the defective in the sensing axes effectively, and contact panel normally carries out touch-control sensing but the transmission line in the contact panel also must be kept good electrical characteristics.Therefore, present embodiment proposes following detection method, and it detects at the transmission line in the contact panel.Figure 14 is the third detection method of the contact panel of one embodiment of the invention.Please refer to Figure 14, this detection method at first is to carry out step 10 contact panel is provided.Contact panel can be as the aforementioned in the contact panel 100,400,700,800 and 900 wherein one.What deserves to be mentioned is that use in the contact panel of this method, insulation course can expose the signal end of transmission line.In addition, can only there be an end that connects signal wire to be provided with detection zone in each sensing axes.
Then, carry out step 40, detect by one of them detection zone and one of them corresponding signal end.For instance, when this detection method is applied to contact panel 100, the mode of carrying out of step 40 for example is that a probe is contacted first detection zone 150 or second detection zone 160 wherein, first simultaneously that another probe contact is corresponding signal end S1b or corresponding secondary signal end S2b.So, by two probe in detecting, first transmission line S1 or the electrical characteristics of the second transmission line S2, with at the defective first transmission line S1 or the second transmission line S2 repairs.Certainly, such detection step also can be applied to contact panel 400,700,800 and 900, to promote the quality of contact panel 400,700,800 and 900.
Generally speaking, the present invention is provided with detection zone in the end of each sensing axes, and insulation course comes out detection zone.Therefore, the present invention can directly detect sensing axes whether defectiveness produce, and transmission line and sensing axes can detect respectively.The detection method of contact panel thereby more efficient.After defectiveness is detected in the contact panel, can further repair at defect part.So, contact panel of the present invention can have good quality.
Though the present invention discloses as above with embodiment; right its is not that any those skilled in the art are under the situation that does not break away from the spirit and scope of the present invention in order to qualification the present invention; can carry out various modifications to the present invention, so protection scope of the present invention is when being as the criterion with claim.
