Contact panel of the present invention, by joint sheet being equally divided into the setting of about two groups transverse directions or the connection wire that tilts, can reducing the area of surrounding zone, thus realize the object of narrow frame.In addition, this design can increase the bounding force of joint sheet and circuit board, is separated with joint sheet to avoid circuit board because of fracture.
Above-mentioned is the general introduction of invention technical scheme, and below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of contact panel of present pre-ferred embodiments;
Fig. 2 is the partial schematic diagram of a kind of contact panel of another preferred embodiment of the present invention.
Embodiment
For further setting forth the present invention for the technological means that reaches predetermined object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1, contact panel comprises a sensing area A, a surrounding zone B, multiple conducting wires 1 and multiple joint sheet 2.Contact panel can use resistance-type, condenser type, optical profile type or other touch technologies, and wherein sensing area A can do corresponding structure change because of the difference of above-mentioned touch technology.In addition, contact panel of the present invention can comprise contact panel or touch-control display panel.And be make graphic succinct to facilitate a kind of contact panel of this explanation present pre-ferred embodiments, therefore do not illustrate structure and the composition of sensing area A.
Surrounding zone B is positioned at around sensing area A, and also namely surrounding zone B can be positioned at least side of sensing area A, and has a bonding land C.In the present invention, sensing area A is roughly a quadrilateral, and surrounding zone B ring establishes sensing area A, and bonding land C is arranged at surrounding zone B and be positioned at the side of sensing area A.Wherein sensing area A has a side L of contiguous bonding land C.It is worth mentioning that, in other embodiments, surrounding zone B also can be positioned at the side of sensing area A or relative both sides, and can configure surrounding zone B according to demand, the present invention does not limit.
Wire 1 is configured at surrounding zone B, and each wire 1 can pass through wires design is collected to bonding land C.Wire 1 can be electrically connected at some sensing element (not shown) of sensing area A, is sent to a circuit board 3 with the sensor signal produced by the sensing element of sensing area A via wire 1.In this, namely bonding land C can be the region that wire 1 overlaps with circuit board 3, and circuit board 3 correspondence fits in the joint sheet 2 of bonding land C.
Joint sheet 2 is arranged at bonding land C, and correspondence is electrically connected those wires 1 respectively.In the present embodiment, each joint sheet 2 spaced-apart relation, and be mutually electrically insulated.Joint sheet 2 can be such as the materials such as molybdenum, aluminium, copper, gold, silver, or the multi-layer conductor leads of aforementioned different materials formation is superimposed, but the present invention does not limit the material of joint sheet, really can be electrically connected wire 1 and circuit board 3 for considering.
Multiple joint sheet 2 is equally divided into two groups and symmetric offset spread is arranged to the left and right.In the present embodiment, multiple joint sheet 2 is that average left and right lateral symmetry is arranged, namely known, the extension line of joint sheet is parallel with sensing area, simultaneously, because the extension line of wire 1 and the side L of the contiguous bonding land C of sensing area A are formed with obtuse angle A1, by such setting, fix at the width of joint sheet 2, and under the constant condition of the total area that contacts with circuit board 3 of joint sheet 2, compared to the joint sheet that the vertical sensing measurement district A commonly used is arranged, the present invention can shorten joint sheet 2 perpendicular to the length on side L direction, to reduce the area of surrounding zone B, thus realize the object of narrow frame, thus under realizing not increasing the prerequisite of contact panel size, screen visible area (corresponding induction zone) is maximized.
In addition, under above-mentioned design can make unit area, circuit board 3 increases with the fitting area of joint sheet 2, thus increases the bounding force of joint sheet 2 and circuit board 3.On the other hand, when circuit board 3 is pullled by external force, this design dispersibles stress, is separated with joint sheet 2 to avoid circuit board 3 because of fracture.Wherein, when the width of joint sheet 2 is wider and to each other apart from time narrower, joint sheet 2 will be larger with the bounding force of circuit board 3.
Fig. 2 is the partial schematic diagram of a kind of contact panel of another preferred embodiment of the present invention.Please refer to Fig. 2, in the present embodiment, multiple joint sheet 2 is symmetrical arranged for average left right bank, namely by joint sheet 2 is tilted to connect wire 1, compared to the joint sheet do not tilted commonly used, because the extension line of the joint sheet 2 of the present embodiment and the side L of the contiguous bonding land C of sensing area A are formed with obtuse angle A2, therefore at the joint sheet 2 times of same length, the present embodiment can shorten the length of joint sheet 2 in vertical side edge L direction, to reduce the area of surrounding zone, thus realizes the object of narrow frame.
In addition, the circuit board correspondence commonly used fits in the part of joint sheet, and fracture is easily caused because not having protective seam in its dew copper region.But, shorten joint sheet 2 in the length perpendicular to side L direction by the design of above-described embodiment, make dew copper region also shorter in the length perpendicular to side L direction, therefore can reduce the regmatic risk of dew copper of circuit board 3.It is noted that the dew copper region alleged by the present invention refers to the region that circuit board is electrically connected in order to fit in joint sheet, not the conductive material of limiting circuit plate is copper.
In addition, surrounding zone B can arrange magnetic conductive ink layer, reaches object attractive in appearance in order to cover wire 1, joint sheet 2 and the circuit space of a whole page 3.
In sum, contact panel of the present invention is equally divided into about two groups transverse directions by joint sheet or tilts to connect the setting of wire, can reduce the area of surrounding zone, thus realize the object of narrow frame.In addition, this design can increase the bounding force of joint sheet and circuit board, is separated with joint sheet to avoid circuit board because of fracture.
The above; be only preferred embodiment of the present invention, not technical scope of the present invention imposed any restrictions, therefore adopt the technical characteristic identical or approximate with the above embodiment of the present invention; and other contact panels obtained, all within protection scope of the present invention.
