The technical scheme that its technical matters that solves the utility model adopts is:
A kind of touch-screen of narrow frame, comprise transparent touch base plate and the induction line layer that is arranged on this touch base plate, this induction line layer comprises a plurality of touch control units that matrix is arranged and a plurality of circuits that are electrically connected with a plurality of touch control units on the induction line layer, be used for the capacitance variations value that the induction line layer senses is exported to process chip, touch-screen also comprise with circuit in the first port of part connection, with the second port of another part connection in the circuit, the first port and the second port are positioned at upside and/or the downside of touch base plate.
In the touch-screen of narrow frame described in the utility model, circuit is flexible PCB.
In the touch-screen of narrow frame described in the utility model, the induction line layer is etched into many along touch control unit and a plurality of touch control unit along y direction of X direction, adjacent along X direction touch control unit and the cross part of the touch control unit of y direction be provided with bridging node insulation, that prevent conducting.
In the touch-screen of narrow frame described in the utility model, touch base plate is glass or PET.
In the touch-screen of narrow frame described in the utility model, the induction line layer is indium tin oxide layer.
In the touch-screen of narrow frame described in the utility model, the induction line layer is double-deck, is separately positioned on the both sides, front and back of touch base plate.
In the touch-screen of narrow frame described in the utility model, capacitance plate also comprises the protective seam that sticks in sensor circuit layer top.
Implementing the beneficial effect that the touch-screen of narrow frame of the present utility model has comprises: because by two port cablings up and down, the Width prior art in the cabling zone of the left and right sides is narrow, not only save to make material, and the result of use of manufactured goods better, more attractive in appearance; The cabling of part circuit is short than prior art, locates more accurate.
Description of drawings
Be described further below in conjunction with the touch-screen of drawings and Examples to the narrow frame of the utility model, in the accompanying drawing:
Fig. 1 is the structural representation of the touch-screen of prior art;
Fig. 2 is the structural representation of an embodiment of the utility model narrow-frame touch panel;
Fig. 3 is the structural representation of another embodiment of the utility model narrow-frame touch panel;
Fig. 4 is the structural representation of another embodiment of the utility model narrow-frame touch panel;
Fig. 5 is the structural representation of another embodiment of the utility model narrow-frame touch panel.
Embodiment
Structure and the principle of the touch-screen of the narrow frame of the utility model are described in conjunction with Fig. 2 to Fig. 5.
For the convenience of describing, definition A-A be laterally, or about claiming, on the plane at paper place with the A-A perpendicular direction be vertical, or deserve to be called down, vertically outside, the inside direction in plane, paper place is called front, back.
As shown in Figure 2, in an embodiment of the touch-screen of narrow frame of the present utility model, it comprises transparent touch base plate 1, the induction line layer is etched on this touch base plate, the induction line layer is divided into a plurality of touch control units that matrix is arranged, touch control unit is connected to the first port 4a or the second port 4b by circuit 3, is connected with process chip by the first or second port again.Further, among this embodiment touch control unit 5 places have the bridging node 5 of the insulation of the touch control unit conducting that prevents vertical and horizontal (A-A) in the point of crossing.The first port 4a and the second port 4b are separately positioned on the up and down both sides of touch base plate in this embodiment, and they are by circuit 3 and the sensing unit connection of close together of being connected.Prior art and this embodiment of Fig. 1 are contrasted as can be known, and the width of the cabling of the left and right sides zone S1, S2 has obviously narrowed down.The length that is not both in addition the part circuit has shortened.Circuit 3 can be adopted as flexible PCB or zebra bar in this embodiment, and touch base plate 1 is glass or PET.The induction line layer is indium tin oxide layer.Capacitance plate also has the protective seam that sticks in sensor circuit layer top in addition.Make according to half circuit of the nearer pact of port to be attached thereto in concrete line design, second half circuit is connected with the another port, will consider simultaneously the problem of the matching between the circuit.
The touch-screen of the narrow frame of Fig. 3 is from the different of Fig. 2: the first port 4a and the second port 4b are arranged on the diagonal position of touch base plate upper and lower sides.It can be that the cabling district of the right and left narrows down equally, thereby the opaque border of cover plate is narrowed down, and saves material, and easy to use.
The touch-screen of the narrow frame of Fig. 4 is from the different of Fig. 2: the first port 4a and the second port 4b are arranged on the position near the centre of touch base plate upper and lower sides.In another embodiment of the present utility model, the first port and the second port are arranged on the same side, namely all at upside or all at downside.
From the setting position of the port of Fig. 2 to Fig. 4 as can be known, the position that port is arranged on the upper and lower side of touch base plate is variable, and they all can make the frame of the left and right sides narrow down.
The touch-screen of the narrow frame of Fig. 5 adopts the mode of monolateral cabling, and it also can make left and right side frame narrow down, and different from above-described embodiment is, in this embodiment, the amplitude of variation of left frame is different.
Those skilled in the art also can make upper and lower frame narrow down according to the circuit set-up mode of the touch screen of narrow frame of the present utility model, this design can be used in people and be accustomed on the equipment such as the horizontal MP4 that uses, E-book reader, not only material can be saved equally, and people's use impression and the aesthetics of product can be improved.
In addition, according to design philosophy of the present utility model, can also design 3,4, even multiport more.This design compared with prior art can make frame narrow down, but compares with above-mentioned several embodiment, and it can more significantly not narrow down frame, still can increase the difficulty of the making of product.Same this cabling mode can be applied in the ITO project organization of single-surface single-layer structure, single-surface double-layer structure or two-sided double-deck structure.
