Please be simultaneously with reference to Figure 1B, it illustrates the top view of the conductive structure of the part among Figure 1A.Though this conductive structure 150 of sentencing in the region R illustrates, yet, have in this technical field and know that usually the knowledgeable should understand the feature of the conductive structure 150 of present embodiment whereby.
Each patterning 153 has a 153a of font portion, one first 153b1 of line portion and one second 153b2 of line portion.The opening 153a1 of the door font 153a of portion is in the face of being positioned at least one of the outside of the 153a of font portion first transversary 151.First 153b1 of line portion and second 153b2 of line portion respectively from the two ends of the door font 153a of portion along laterally extending in contrast to the direction of the door font 153a of portion.
Second transversary 155 disposes alternately with the door font 153a of portion of patterning 153, and is positioned at least one the inboard of one first 153b1 of line portion and one second 153b2 of line portion.
By the conductive structure 150 of input voltage at contact panel 100, conductive structure 150 produces an electric field accordingly at conductive layer 130 places.Because the design of first transversary 151, the electric field of generation can distribute equably.In addition, second transversary 155 with make cooperating of patterning 153 electric field magnitude of voltage from voltage input end toward voltage not the direction of input end successively decrease.Thus, the electric field of contact panel 100 can have the favorable linearity performance, makes contact panel 100 can judge touched position exactly.
Now the contact panel 100 with present embodiment further specifies as follows.The edge of the substrate 110 among Figure 1A has four sides, marks with label 111,113,115 and 117 respectively.Side 111 and side 115 are parallel to each other in fact, and side 113 and side 117 are parallel to each other in fact.In the present embodiment, conductive structure 150 is a pair of axisymmetric shape.That is to say that the conductive structure 150 that is positioned at side 111 places is symmetrical in the conductive structure 150 that is positioned at side 115 places, and the conductive structure 150 that is positioned at side 113 places is symmetrical in the conductive structure that is positioned at side 117 places.
