Embodiment

The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.

Please referring initially to shown in Fig. 1, the contact panel 10 of one embodiment of the invention is main to include a substrate 108, and sets In 102 and one bucking electrode 106 of sensing electrode structure one of on substrate 108.Foregoing sensing electrode structure 102 includes at least 1 the One first axis electrode 102a and at least one second axial electrode 102b (have a plurality of first axis electrodes in the present embodiment 102a and a plurality of second axial electrode 102b), wherein those first axis electrodes 102a (sensing electrode) system is parallel to Y-axis Arrangement, and those second axial electrodes 102b (sensing electrode) systems arrange parallel to X-axis.First axis electrode 102a and the second axis It is preferably to be mutually perpendicular in the present embodiment to being non-parallel relation between electrode 102b.Foregoing bucking electrode 106 then surrounds foregoing The periphery of sensing electrode structure 102.

Please continue to refer to be also provided with shown in Fig. 1, on aforesaid base plate 108 a plurality of conducting wires 110 and at least one ground wire 112 (the present embodiment includes two ground wires 112), one end system of wherein those conducting wires 110 is electrically connected foregoing first Axial electrode 102a and the second axial electrode 102b, and its other end then with a circuit board (such as flexible circuit board, not shown) Upper circuit is connected.The scope that foregoing first axis electrode 102a and the second axial electrode 102b are covered can form a sensing Functional areas S, can sense the touch from the external world, and form of its positional information through electric signal is sent to aforementioned circuit Plate, thereby to realize the man-machine interface of a touch-control sensing.In addition, foregoing ground wire 112 is then electrically connected bucking electrode 106 with before The ground terminal on circuit board is stated, bucking electrode 106 is capable of providing the function of prevention electrostatic interference accordingly, and electrostatic can be avoided to enter Sensing function area S and the touch-control menu that influences device show.

In this present embodiment, foregoing sensing electrode structure 102, bucking electrode 106, conducting wire 110 and ground wire 112 are all set The lower surface of substrate 108 is placed in, thereby those electrodes can be avoided to be subject to scratch and influence the reliability of device.It is in addition, foregoing The confluce of first axis electrode 102a and the second axial electrode 102b are also provided with insulation system 104, to avoid two axis To electrode form short circuit.

Then also referring to shown in Fig. 1, Fig. 2A, foregoing bucking electrode 106 is ring-type, its circular profile in the present embodiment For rectangle, the hollow-out parts 106a formed with two long and narrows wherein on short side side (side of part A as shown in Figure 1).This implementation In example, the hollow-out parts 106a of foregoing long and narrow is preferably arranged in parallel along the long axis direction (X-axis) of bucking electrode 106, and court Short-axis direction (Y-axis) extension of bucking electrode 106.In an embodiment, foregoing hollow-out parts 106a also can be odd number or More.

, also can be formed with plural number in foregoing bucking electrode 106 in another embodiment of the present invention (as shown in Figure 1, Figure 2 shown in B) The hollow-out parts 106a of a long and narrow, and those hollow-out parts 106a is tied up on the short-axis direction (Y-axis) of bucking electrode 106 to be separated by one Apart from form be arranged at intervals, and in arranged in parallel on the long axis direction (X-axis) of bucking electrode 106, wherein those are (in short axle On direction) the hollow-out parts 106a of different row is on short-axis direction (Y-axis) in can form Heterogeneous Permutation.Alternatively, in an embodiment it Those hollow-out parts 106a also can be only arranged on single row, and on short-axis direction (Y-axis) in the form of spaced a distance interval Set.

It is to be understood that foregoing hollow-out parts 106a can be formed at the long side 1061 of bucking electrode 106, corner 1062 or The one of the group (including the short side side of bucking electrode 106, long side 1061 and corner 1062) of above-mentioned position grouping, it is It is distributed according to assembling situation (later illustrate in introduce) of the contact panel 10 in a touch control display.

Above-described embodiment is that the present invention will be described in detail so that the shape of bucking electrode ring-type is rectangle as an example.It is actual On, the needs of the shape of the bucking electrode ring-type also visual actual product are circular, polygon or other irregular figures.

Through the structure design of above-described embodiment, when the shell 20 of 10 and one touch control display D of contact panel is assembled (the display assembling schematic diagram for referring to Fig. 3 expressions), although bucking electrode 106 (short side side, long side or corner) Generation crack under external force (arrow as shown in Figure 3) effect that shell 20 may be abutted and applied in assembling, but due to For bucking electrode 106 with 20 intersection of shell formed with (hollow-out parts 106a) is partly hollowed out, hollow-out parts 106a can hinder crack Sprawling, it is thus possible to the problem of avoiding whole bucking electrode 106 from being broken, thereby accounting for the failure of product antistatic effect, and and then The reliability of product can be lifted.

Although the present invention is disclosed above with foregoing embodiment, so it is not limited to the present invention.Skill belonging to the present invention Has usually intellectual in art field, without departing from the spirit and scope of the invention, when a little change and retouch can be done.Cause The scope of protection of the present invention shall be subject to the definition of the patent scope appended hereto for this.
