Abstract
The present invention discloses a thin-film touch induction screen, comprising a touch induction thin film and a controller. The touch induction thin film comprises an induction layer formed by a plurality of horizontal leads and longitudinal leads that are insulated from each other and are arrayed in a longitude and latitude lattice shape, a flexible circuit connector that connects an induction zone with the controller, and transparent protective layers covering two sides of the induction layer. The longitudinal leads are arrayed in a high-curvature wave line shape. The horizontal leads are arrayed in a low-curvature relatively-flat curve shape. Two or more rows of bonding pads are arrayed in a crossing manner on the flexible circuit connector. The efficiency of 3D printing wiring is greatly improved, anti-breaking performance is improved, the lead arraying area is increased, and touch sensitivity is improved. By increasing the drifting distance of the horizontal leads and the longitudinal leads, electromagnetic interference between the horizontal leads and the longitudinal leads is lowered, stability is greatly improved; and the bonding pads of a flexible circuit connecting board are in a multi-row mode, so the size of the flexible circuit connecting board is reduced, and moreover manufacturing cost is lowered.

It is characterized in that: described longitudinal wire is the wave wire arrangement of deep camber, and horizontal wire is little curvature
The most open and the most flat curve-like arrangement；The described pad on flexible circuit connector is the staggered rows of more than 2 rows
Cloth.
Preferably, the whipping part of the horizontal wire of touch-control sensing layer is protected in the middle of the whipping part of longitudinal wire
Hold the distance of more than at least 2 millimeters, reduce electromagnetic interference each other.
Preferably, the whipping part of the horizontal wire of touch-control sensing layer and the whipping part of longitudinal wire are in up and down
2 layers of wire laying mode, and it is provided with electro-magnetic screen layer between 2 layers.
Preferably, the horizontal wire of touch-control sensing layer can exchange with longitudinal wire.
Preferably, the horizontal wire of touch-control sensing layer and longitudinal wire through pad be back-shaped needle-like curve or
Spirality is arranged, and increases welding contact area and increases weld strength.
Further, horizontal wire and longitudinal wire of described inductive layer uses 3D printing type will have absolutely
The ultrafine wire of edge outer layer is directly printed upon on transparent protective film.
The prominent effect of the present invention is: change the arrangement method of tradition ultrafine wire, from original with
The multi straight wiring method of corner angle changes over free curve formula and walks collimation method, substantially increases 3D and prints the effect of wiring
Rate；And free curve formula cabling decreases the stress within wire so that it is the anti-performance that fractures is greatly improved；
Use the wave wiring method of deep camber, add line conductor row cloth area, make touching signals strengthen, improve
Touch-control sensitivity；By increasing the distance of horizontal line wire and longitudinal wire whipping, decrease electricity each other
Magnetic disturbance, stability is greatly improved；The welded disc of flexible circuit connecting plate uses multiple rows of pattern, reduces soft
The size of property circuit connecting plate, reduces manufacturing cost simultaneously.
Hereinafter accompanying drawing the most in conjunction with the embodiments, is described in further detail the detailed description of the invention of the present invention, so that
Technical solution of the present invention is more readily understood, grasps.

Detailed description of the invention
Film touch-control sensing screen, including touch-control sensing film and controller；Touch-control sensing film includes again: many
The sensing that the horizontal wire (2) of bar mutually insulated and longitudinal wire (1) graticules trellis arrangement are formed
Layer, connects the flexible circuit connector (5) of induction zone and controller, and cover in inductive layer both sides saturating
Bright protective layer.
As it is shown in figure 1, be the line conductor row mode for cloth of current existing a kind of touch-control film, longitudinal wire
(1) rectangular arrangement, horizontal wire (2) is linearly arranged.Fig. 2 is the partial enlarged drawing of Fig. 1,
The whipping part (3) of longitudinal wire (1) nestles up the whipping part (4) of horizontal wire (2).
Longitudinal wire (1) is that multistage orthoscopic walks collimation method when arrangement, so can form many right-angled apices, 3D
Printer is these apex when wiring, can be substantially reduced the speed of wiring, thus cause printing effect very
Low, and can be because the existence of stress at these apex, the probability causing broken string is the biggest.
As it is shown on figure 3, the bending row that the arrangement of longitudinal wire (1) and horizontal wire (2) is in multistage straight line
Cloth, such arrangement makes 3D printing effect promote, but still can form many summits, easily makes
Become broken string.
Fig. 4 is a kind of wiring method of the present invention, and longitudinal wire (1) uses the waveform of deep camber freely
Curve is arranged, and horizontal wire (1) uses the most open and the most flat free curve arrangement of little curvature, free curve
Formula wiring makes the wiring efficiency of 3D printer be greatly improved, and due to the existence without drift angle, outage is big
Big lifting, and the area that wire covers is bigger, and touch-control sensitivity also can be improved.Fig. 5 is Fig. 4
Close-up schematic view, as we can see from the figure the whipping part (3) of longitudinal wire (1) with laterally lead
The whipping part (4) of line (2) keeps the distance of at least more than 2mm when wiring, is primarily due to
Longitudinal wire (1) is signal transmitting terminal, and horizontal wire (2) is signal receiving end, the whipping of horizontal wire
When partly the whipping part (3) of (4) and longitudinal wire is close to arrangement, it is easy to cause electromagnetic interference,
Affect sensitivity and the stability of touch-control.The whipping part (4) of horizontal wire and the whipping portion of longitudinal direction wire
Divide (3) one layer of electro-magnetic screen layer can be increased therebetween, reduce that in the way of using 2 layers of arrangement
This signal disturbing.
As shown in Figure 6, it is a kind of structural representation of flexible circuit connector (5) of existing film touch screen
Figure, Fig. 7 is the partial enlarged drawing of Fig. 6, the single side being arranged in flexible connector of pad (6), separately
Side is connected to the whipping part (4) of horizontal wire and the whipping part (3) of longitudinal wire.
As shown in Figure 8, the upper pad (6) of the flexible circuit connector (5) of the present invention is in about 22
Row is staggeredly placed, and Fig. 9 is the close-up schematic view of Fig. 8, it can be seen that such arrangement can be contracted significantly
The length of short flexible circuit connector (5), increase touch-control film and other devices with the use of spirit
Activity, has saved manufacture material and cost simultaneously.
It is that the ultrafine wire of existing film touch-control sensing screen is in the wiring side through pad as shown in Figure 10
Formula, the central authorities of a wire straight-line pass pad, such wire laying mode is easy to because welding when welding
Precision causes sealing-off or not prison welding solid not, causes entire film touch-control sensing screen without non-usage.Figure
11 be the ultrafine wire of the present invention at the wire laying mode through pad, by walking the wiring of a clip type
Structure, adds the contact area of ultrafine wire and pad, welding more firm, greatly reduces rosin joint
Or sealing-off, adds the yield of finished product.
The present invention is not limited to aforementioned embodiments, and those skilled in the art are in the enlightenment of the technology of the present invention marrow
Under, it is also possible to make other changes, but as long as its function realized is same or similar with the present invention, all should belong to
In protection scope of the present invention.
