To the problem among the above-mentioned prior art, the utility model provides a double-deck ITO touch-sensitive screen function piece to this implements once only to bind the pressfitting molding, and improves the production efficiency of touch-sensitive screen function piece.

The utility model discloses a following technical scheme implements: a double-layer ITO touch screen functional sheet comprises an upper OCA layer, an upper ITO layer, a lower OCA layer and a lower ITO layer. Wherein, go up OCA layer bottom attached being equipped with in proper order go up the ITO layer OCA layer down with lower ITO layer, it is equipped with a plurality of PIN interfaces of going up to go up ITO layer bottom, ITO layer bottom is equipped with at least one PIN interface down through the holder connection down, the holder side is L shape frame, down the PIN interface and with the interconnecting link on ITO layer all is fixed in down on the holder, down the PIN interface with the upper surface of going up the PIN interface flushes.

Furthermore, the upper PIN interface and the lower PIN interface are both connected to a golden finger interface of the FPC.

Further, the lower PIN interface is located in the middle of the arrangement area of the plurality of upper PIN interfaces.

Furthermore, the lower PIN interface is attached to one surface of the L-shaped frame of the retainer.

Furthermore, UV glue is filled in a gap between the retainer and the bottom end of the upper ITO layer.

Further, the holder is made of an insulating material.

The utility model has the advantages that: this device can be under the function condition of walking the line not influencing, and through the department PIN interface position design of binding on upper and lower ITO layer for the coplanar, the touch-sensitive screen function piece of making its constitution and FPC accessible conducting resin membrane can once only bind the pressfitting type when binding the board and snatching both sides mark, effectively improve the production efficiency of touch-sensitive screen function piece.

Drawings

fig. 2 is a partial cross-sectional view of an embodiment of the invention;

in the figure: 1-upper OCA layer, 2-upper ITO layer, 2 a-upper PIN interface, 3-lower OCA layer, 4-lower ITO layer, 4 a-lower PIN interface, 5-holder, 6-UV glue and 7-FPC.

Detailed Description

The invention is described in further detail below with reference to the drawings and examples.

As shown in fig. 1-2, a double-layer ITO touch screen functional sheet includes an upper OCA layer 1, an upper ITO layer 2, a lower OCA layer 3, and a lower ITO layer 4. Wherein, go up 1 bottoms on OCA layer and attach in proper order and be equipped with ITO layer 2, lower OCA layer 3 and lower ITO layer 4, it is equipped with two PIN interfaces 2a to go up 2 bottoms on ITO layer, lower ITO layer 4 bottom is connected through holder 5 and is equipped with a lower PIN interface 4a, holder 5 side is L shape frame, lower PIN interface 4a and with down ITO layer 4's interconnecting link all be fixed in on holder 5, lower PIN interface 4a flushes with the upper surface of last PIN interface 2 a.

Because the L-shaped retainer 5 guides the circuit of the lower PIN interface 4a and provides the lower PIN interface 4a with an installation fixing position protruding out of the lower ITO layer 4, the surface of the lower PIN interface 4a is flush with the surface of the upper PIN interface 2a, and under the condition that functional wiring is not affected, the positions of the upper PIN interface 2a and the lower PIN interface 4a are designed into the same plane, so that a touch screen functional sheet formed by the touch screen functional sheet and an FPC7 can be bound and pressed at one time when the left and right side areas of the PIN interface are captured by a binding machine table through a conductive adhesive film, the upper PIN interface 2a and the lower PIN interface 4a are connected with a golden finger interface of the FPC7 to form quick binding connection, and the production efficiency of the touch screen functional sheet is effectively improved.

In this embodiment, the lower PIN interface 4a is located in the middle of the arrangement region of the two upper PIN interfaces 2a, so as to ensure the stress balance after being bound with the FPC 7.

In this embodiment, the gap between the holder 5 and the bottom end of the upper ITO layer 2 is filled with the UV glue 6, and the holder 5 is mounted and positioned by using the characteristic of fast curing speed of the UV glue 6, so as to further improve the production efficiency of the touch screen functional sheet.

In this embodiment, the lower PIN interface 4a is attached to one surface of the L-shaped frame of the holder 5, preferably to the vertical surface shown in fig. 2, so that the lower PIN interface 4a does not roll back, and is attached to the vertical surface of the L-shaped frame of the holder 5, thereby ensuring that the lower PIN interface 4a and the upper PIN interface 2a are kept flush at any time.

In this embodiment, the holder 5 is made of an insulating material, so that the lines arranged on the holder 5 are protected from electrical interference, ensuring proper conduction of the lines of the lower PIN jack 4 a.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and it should be understood that the embodiments can be replaced by other equivalents, which are equivalent to the embodiments described above, and are included in the scope of the present invention, which is defined by the appended claims.
