Embodiment
As shown in Figure 1A, the substrate 10 of contact panel 100 has Touch Zone 13, Touch Zone 13 is provided with multiple induction electrode 131.Substrate 10 does not have the region of induction electrode 131 as non-touch-control district 14, and non-touch-control district 14 surrounds Touch Zone 13.Metal routing 11 on substrate 10 is positioned in non-touch-control district 14, and is electrically connected to multiple induction electrodes 131 of Touch Zone 13.Metal routing 11 is electrically connected to connection pad 15, and connection pad 15 can be electrically connected to again external circuit as flexible circuit board (not shown).The electric current of external circuit or signal can be passed to Touch Zone 13 via connection pad 15 and metal routing 11, impel contact panel 10 to operate.In an embodiment of the present invention, the material of substrate 10 can be glass or plastic cement.In an embodiment of the present invention, the material of metal routing 11 can be aluminium, molybdenum, copper, silver, above-mentioned alloy or above-mentioned sandwich construction, and the material of connection pad 15 can be tin indium oxide (ITO) or indium zinc oxide (IZO).
Protective seam 17 covers and protects metal routing 11 and Touch Zone 13.As shown in Figure 1A, the distance between the edge of protective seam 17 and all metal routings 11, as D1, D2 and D3, is all at least greater than 140 microns.If the distance between the edge of protective seam 17 and arbitrary metal routing 11 is less than 140 microns, extraneous aqueous vapor may be had in use for some time and infiltrate between substrate 10 and protective seam 17, and then corroding metal cabling 11 reduce the fiduciary level of contact panel 100.As for the ultimate range between the edge of protective seam 17 and all metal routings 11, then change to some extent according to the edge of substrate 10 and the distance of metal routing 11.In an embodiment of the present invention, the edge of substrate 10 and the distance of metal routing 11 are 390 microns.Therefore, in the above-described embodiment, the ultimate range between the edge of protective seam 17 and all metal routings 11 is 390 microns.But above-described embodiment is not in order to limit the present invention.Be understandable that, the distance between the edge of substrate 10 and outermost metal routing 11 must be more than or equal to 140 microns.If the edge of substrate 10 and the distance of metal routing are less than 140 microns, even if protective seam 17 covers all substrates 10, the distance between the edge of protective seam 17 and outermost metal routing 11 must be less than 140 microns and effectively cannot intercept aqueous vapor.In an embodiment of the present invention, protective seam 17 can be light-hardening resin or thermosetting resin.
Fig. 2 A is the cut-open view of the hatching line A-A along Figure 1A, and Fig. 2 B is the cut-open view of the hatching line B-B along Figure 1A.As shown in Fig. 1 and Fig. 2 B, because connection pad 15 need extend protective seam 17 to be electrically connected to external circuit, the metal routing 11 on connection pad 15 and the distance D3 between the edge of protective seam 17 short especially.But distance D3 still needs to be greater than 140 microns.If the distance between the edge of protective seam 17 and arbitrary metal routing 11 is less than 140 microns, extraneous aqueous vapor may be had in use for some time and infiltrate between connection pad 15 and protective seam 17, and then corroding metal cabling 11 reduce the fiduciary level of contact panel 100.
Although it should be noted that the connection pad 15 of Fig. 2 B below between metal routing 11, connection pad 15 also can be positioned at above metal routing 11, looks closely design and determines.No matter the position of connection pad 15 why, as long as electrical connection metal routing 11 and external circuit (not shown) can be reached.
In the embodiment shown in Fig. 2 A and Fig. 2 B, protective seam 17, except covering metal cabling 11 is with except connection pad 15, also successionally extends to Touch Zone 13, and the so-called Touch Zone 13 of comprehensive covering.But in other embodiments of the present invention, protective seam 17 can not cover Touch Zone 13, or only cover the subregion of Touch Zone 13.The protective seam 17 of this kind of selectivity covering has the first edge 17A be positioned in non-touch-control district 14, and the second edge 17B extended to Touch Zone 13 by non-touch-control district 14.
In the embodiment shown in Figure 1B, the second edge 17B of protective seam 17 is between induction electrode 131 and metal routing 11.The hatching line A-A of the corresponding Figure 1B of Fig. 2 C, and the hatching line B-B of the corresponding Figure 1B of Fig. 2 D, wherein, the distance D4 between the second edge 17B of protective seam 17 and metal routing 11 need at least be greater than 140 microns.
In the embodiment shown in Fig. 1 C, the second edge 17B of protective seam 17 is positioned on induction electrode 131.The hatching line A-A of Fig. 2 E corresponding diagram 1C, and the hatching line B-B of Fig. 2 F corresponding diagram 1C, wherein, the distance D5 between the second edge 17B of protective seam 17 and metal routing 11 need at least be greater than 140 microns.In the embodiment shown in Figure 1B (and Fig. 2 C and Fig. 2 D) Yu Fig. 1 C (and Fig. 2 E and Fig. 2 F), Touch Zone 13 do not have protective seam 17 in fact.Thus, when contact panel and display panel are integrated into touch control display apparatus, the light transmittance of contact panel its viewing area overlapping in fact with Touch Zone 13 can be improved further.
Above-mentioned contact panel 100 can be integrated in existing any touch control display apparatus.As shown in Figure 3, contact panel 100 can be located between display panel 305 and cover plate 310, and the black matrix" 320 of cover plate 310 is overlapping with connection pad 15 with the metal routing 11 of contact panel 100, to complete contactor control device 300, it is so-called GG (glasstoglass) structure.Although it should be noted that the design of corresponding Figure 1A, Figure 1B and Fig. 1 C of contact panel that Fig. 3 is corresponding also can be used in touch control display apparatus.
As shown in Figure 4, contact panel 100 can be integrated into display panel 405, and namely the substrate 10 of contact panel 100 also can be used as the upper substrate of display panel 405.In other words, metal routing 11, Touch Zone 13, to be directly formed on the upper substrate (sign) of display panel 405 with connection pad 15, then to get cover plate 310 and cover said structure, and the black matrix" 320 of cover plate 310 is overlapping with metal routing 110 and connection pad 15.To complete contactor control device 400, it is so-called TOD (Touchondisplay) structure.Although it should be noted that the design of corresponding Figure 1A, Figure 1B and Fig. 1 C of contact panel that Fig. 4 is corresponding also can be used in touch control display apparatus.
As shown in Figure 5, first form black matrix" 510 on the substrate 10, then formed metal routing 11, Touch Zone 13, with connection pad 15 on substrate 10, namely complete contact panel 100.Above-mentioned black matrix" 510 is overlapping with metal routing 11 and connection pad 15, is namely located between substrate 10 and metal routing 11.Then contact panel 100 is covered display panel 505, namely substrate 10 is as the cover plate of touch control display apparatus 500, and to complete touch control display apparatus 500, it is so-called OGS (Oneglasssolution) structure.Although it should be noted that the design of corresponding Figure 1A, Figure 1B and Fig. 1 C of contact panel that Fig. 5 is corresponding also can be used in touch control display apparatus.
It should be noted that the contact panel of subject application is not limited to said structure.The contact panel of any employing protective seam protection metal routing, all can apply above-mentioned specification to improve product property.
