Please refer to Fig. 1 and Fig. 2, show the local upper schematic diagram of the touch-control module of one embodiment of the invention and the cross-sectional schematic along the x-x profile line in Fig. 1 respectively.As shown in the figure, the touch-control module 1 of the present embodiment comprises the contact panel 10 and a flexible circuit board (Flexible Printed Circuit, FPC) 20 that are electrically connected to each other.Wherein, contact panel 10 comprises substrate 11, electrode layer 12, a plurality of splice terminal (Bonding Pad) 13 and a plurality of auxiliary mat (Auxiliary Pad) 14.
One surface of substrate 11 has been defined a bonding land A, and substrate 11 is fitted with flexible circuit board 20 by a conducting resinl 30 on described bonding land A.Electrode layer 12 can be such as the transparency conducting layer be formed on substrate 11 through a patterning process, is used for the use of the touch-control sensing realizing contact panel 10.Splice terminal 13 be formed at substrate 11 surface and be positioned at described bonding land A, in design, splice terminal 13 can be such as be electrically connected with electrode layer 12 by a wire 15, and is electrically connected flexible circuit board 20 by conducting resinl 30.Auxiliary mat 14 be formed at substrate 11 surface and be positioned at described bonding land A, specifically, the auxiliary mat 14 of the present embodiment is the similar face being formed in substrate 11 with splice terminal 13, and at least part of auxiliary mat 14 is formed with splice terminal 13 to be spaced alternately.
It is worth mentioning that, the auxiliary mat 14 of the present embodiment can adopt conduction or non-conductive material in design, as long as concrete material can allow conducting resinl 30 to the tackness of material that adopts carry out get Geng Jia compared to the tackness of the material to substrate 11.For example, auxiliary mat 14 can adopt the material identical with splice terminal 13, as: the conducting metals such as silver, copper, or also can adopt the material identical with electrode layer 12, as conductive materials such as tin indium oxides (Indium Tin Oxide, ITO).In concrete experimental data, when the material of auxiliary mat 14 is tin indium oxide, average tension between contact panel 10 and flexible circuit board 20 is 1.43 newton, and identical in all the other conditions, only remove auxiliary mat 14, the average tension between contact panel 10 and flexible circuit board 20 drops to 0.23 newton.Certainly, if auxiliary mat 14 is actual is the words adopting conductive material to design, those skilled in the art can understand, interval one safe distance can be designed between spaced splice terminal 13 and auxiliary mat 14, avoid, between splice terminal 13 and auxiliary mat 14, capacitance coupling effect occurs, but actual safe distance is not for the present invention is limited, actual be the size of consideration bonding land A, the quantity of splice terminal 13, size and auxiliary mat 14 and splice terminal 13 material etc. because usually adjusting.
In addition, because auxiliary mat 14 can adopt the material identical with splice terminal 13 or electrode layer 12, therefore the auxiliary mat 14 of the present embodiment can be formed on same processing procedure with splice terminal 13 or electrode layer 12 on processing procedure, can not increase the fabrication steps of whole touch-control module 1.Moreover, those skilled in the art can understand, general in the splice terminal 13 of contact panel 10 or the processing procedure of electrode layer 12, target is normally first utilized after sputter deposition becomes whole piece rete, unwanted region is removed again by etching, finally realize required function with the region stayed, therefore the present embodiment more can reduce with the design of the auxiliary mat 14 of splice terminal 13 or electrode layer 12 same material the region etching and remove by increasing, and effectively reduces the waste of material.
The framework of touch-control module 1 from the above, the contact panel 10 of the present embodiment is after having fitted by conducting resinl 30 and flexible circuit board 20, splice terminal 13 and auxiliary mat 14 are between substrate 11 and conducting resinl 30, in other words, this framework can reduce the area that substrate 11 directly contacts conducting resinl 30.Thus, because the material of the auxiliary mat 14 of the present embodiment has better tackness compared to the material of substrate 11 to conducting resinl 30, therefore when being subject to External Force Acting, can reduce the chance that contact panel 10 and conducting resinl 30 occur to peel off, and then circuit stably between maintenance contact panel 10 and flexible circuit board 20 is online.
