Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the part plan schematic diagram according to the contact panel 100 of one of the utility model embodiment.As shown in Figure 1, contact panel 100 comprises at least one joint sheet (bonding pads) 108, touch-control sensing structure 102 and at least one protecting component 112.In Fig. 1, with 8 joint sheets 108, illustrate, but not as limit these joint sheet 108 spaces and be arrangeding in parallel.The form of touch-control sensing structure 102 can be the known any pattern of those having an ordinary knowledge in this technical field and structure, is not described in detail in this.Touch-control sensing structure 102 is electrically connected to the joint sheet 108 of correspondence via plural wires 106, these joint sheets 108 engage with a plurality of metal gaskets (not drawing) on flexible printed wiring board 114 via conducting resinl (not drawing), the sensing signal of touch-control sensing structure 102 can, via wire 106, joint sheet 108, conducting resinl and flexible printed wiring board 114, be sent to outside signal processor (not drawing) and process.
According to one of the utility model embodiment, contact panel 100 also can comprise a light shield layer 104, by light shield layer 104, contact panel 100 is distinguished to visible area V and non-visible area NV, light shield layer 104, joint sheet 108 and wire 106 are positioned at non-visible area NV, and touch-control sensing structure 102 is positioned at visible area V.Joint sheet 108 is to be formed on the light shield layer 104 that is positioned at non-visible area NV; and on these joint sheets 108, be formed with protecting component 112, protecting component 112 can be protected at least one side of these joint sheets 108 to reduce it affected by environmental attack or other processing procedure.
The summary of only drawing protecting component 112 in Fig. 1 forms region; do not draw the detailed structure of protecting component 112; follow-up various embodiment floor map and the diagrammatic cross-section that refers to protecting component shown in subsequent figure 2A to Fig. 7 B 112 and joint sheet 108, and the various structural designs of protecting component 112 are provided, and details are as follows.
Fig. 2 A implements floor map according to one of the protecting component that dashed region A illustrated in Fig. 1 and joint sheet.As shown in Figure 2 A, each joint sheet 108 has the first long side 108A, the second long side 108B, the first short side 108C and the second short side 108D, wherein, the first long side 108A in abutting connection with the first short side 108C and the second short side 108D and with the second long side 108B subtend setting, the first short side 108C is electrically connected by wire with touch-control sensing structure (Fig. 2 A does not show).Along joint sheet 108 long sides and short side, orthogonal long axis direction L and short-axis direction S have been defined respectively, the first long side 108A, the second long side 108B system are arranged in parallel along this long axis direction L, and the second short side 108C, the second short side 108D are arranged in parallel along this short-axis direction S.Protecting component 112 is arranged on the first long side 108A and the second long side 108B of joint sheet 108; to shelter from the first long side 108A and the second long side 108B, avoid the first long side 108A and the second long side 108B expose and affected by environmental attack or other processing procedure.Preferably, be positioned at 108 liang of long sides of joint sheet protecting component 112 upper surface at least with the upper surface flush of joint sheet 108.Because the area of the first short side 108C and the second short side 108D is less; and the first short side 108C also docks with touch-control sensing structure; therefore even the first short side 108C and the second short side 108D are subject to the impact of environment or other processing procedures; its suffered influence degree is also less, therefore protecting component can be set at the first short side 108C and the second short side 108D.But in order more comprehensively to protect the side of joint sheet 108, in other embodiments, protecting component 112 is more arranged at the second short side 108D, to shelter from the second short side 108D, can further improve the phenomenon that the second short side 108D of joint sheet 108 is etched.The material of protecting component 112 can be insulating material, for example pi (polyimide; PI), can form protecting component 112 by coating, exposure and developing manufacture process, or also can directly form by printing process the pattern of protecting component 112.Joint sheet 108 can be by the first metal layer, the second metal level and the 3rd metal level are formed by stacking from top to bottom, the first metal layer and the 3rd metal level are slightly to have a conducting element of defencive function, for example can be by molybdenum, chromium, titanium, the materials such as molybdenum niobium alloy form, the second metal level is for strengthening the electric conductivity of joint sheet, can adopt preferably material of electric conductivity, for example can be by aluminium, the materials such as aluminium neodymium alloy form, in another embodiment, because the first metal layer and the 3rd metal level are slightly to have a conducting element of defencive function, therefore so-called protecting component 112 is arranged on the first long side 108A and the second long side 108B of joint sheet 108, also can only refer to that protecting component 112 is arranged on the both sides long side of the second metal level.
In conjunction with reference to figure 1 and Fig. 2 A; in another embodiment; protecting component 112 more extends and is covered on wire 106; can to wire 106, there is protection effect simultaneously; and because wire 106 does not need to engage with flexible printed wiring board 114, therefore the protecting component 112 being covered on wire 106 can be the insulativity protecting component of a whole layer.Or, in other embodiments, wire 106 also can be otherwise or element protect.
The diagrammatic cross-section of the contact panel that Fig. 2 B system illustrates along the profile line 2-2 ' of Fig. 2 A.As shown in Fig. 1 and Fig. 2 B, contact panel also comprises that one has the cover plate 101 of lower surface, and light shield layer 104 is arranged at the lower surface of cover plate 101 and cover plate 101 is distinguished to visible area V and non-visible area NV.Touch-control sensing structure 102 is arranged at the lower surface of cover plate 101 and is positioned at visible area V.Joint sheet 108 is formed on light shield layer 104, is also that light shield layer 104 is arranged between cover plate 101 and joint sheet 108.The upper surface of cover plate 101 is a touching face for user's touching.
Due to other element forming contact panel, when processing procedures such as the micro-shadow of employing and etching forms touch-control sensing structure, the edge of joint sheet 108 is easily by the erosion of acid & alkali liquid and cleaning fluid, and it is easier of contact area is compared with the impact that is greatly more easily subject to other processing procedure with the quality that engages, the particularly long side of joint sheet 108 of flexible printed wiring board to affect joint sheet 108.According to the embodiment of the utility model, at least two long side 108A and the 108B of each joint sheet 108 are all protected blocking of element 112 and are unlikely to expose, and therefore can effectively improve the problem that joint sheet 110 edges are etched.
In addition; the contact panel of above-described embodiment is formed with protecting component 112 on joint sheet 108; even therefore in the sputter process of deposition joint sheet 108; the gas that forms the black photoresistance release of light shield layer 104 can affect the adhesion between joint sheet 108 and light shield layer 104; two long side 108A that are covered in joint sheet 108 and 108B by the protecting component 112 of the present embodiment; can improve the adhesion between joint sheet 108 and light shield layer 104, that improves joint sheet 108 peels off from light shield layer 104 phenomenon coming off.
