The touch screen requirement that it is used is also higher and higher, not only requires appearance looks elegant, also requires cheap.In order to reduce cost, very much
Chevron Research Company (CRC) replaces the touch screen of double-deck or bridge joint IT0 composition using single layer IT0.
The product of present touch-control mainstream in the market is OGS and GIF, and OGS is that Lens and sensor is integrated, usually
First strengthen, then plated film, etches, finally cut.Cutting cost is high in strengthened glass, and yield is low, and causes glass edge edge
Some capillary cracks are formed, these cracks reduce the intensity of glass.What OGS scheme used is the bridge joint of mutual capacitance mostly simultaneously
Technique, bridge process is more complicated, at high cost, and finished product yield is low, and metal bridge joint bottom shadow is obvious, influences appearance.As GIF-
Using triangle or rectangular patterns, mostly use silk screen printing process greatly, although cost slightly reduces, silk-screen GAP be 0.2~
0.3mm, if not doing the shadow processing that disappears, bottom shadow clearly, and can be unable to satisfy narrow frame requirement, and most importantly structure is mostly
Self-capacitance, single-point add gesture, it is difficult to the interference problem of LCD be overcome to cannot achieve the multi-point touch requirement of four cun or more TP.In order to
Cost is reduced, the touch function of mutual tolerance multiple spot is realized on single layer ITO, and also to improve the bottom that TP and LCD interference generates
Shadow problem provides the new single layer IT0 wire structures of one kind to realize above-mentioned target.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.Single layer multiple spot mutual capacitance used herein
IT0 electrode layer can effectively reduce the thickness of projection-type capacitive touch screen, and the single layer IT0 electrode layer in the application is not
Made of traditional single-layer electrodes bridging technique, but constitute in the following manner
Single layer IT0 wire structures of the present invention are as depicted in figs. 1 and 2 walked by actual induction blind area 11, driving
Line blind area 12, matching interval blind area 13 form, and actual induction blind area 11 repeats electrode unit by multiple groups and forms, and repeat electrode unit
By column-shaped repeated arrangement, and form multiple column.Every two repeats electrode unit and arranges face-to-face.Cabling blind area 12 is driven to be located at two
It is a to repeat between electrode unit, it is made of each lead-out wire for repeating the driving electrodes in electrode unit, every lead-out wire all draws
To the top-Bonding padl4 of touch screen, while suspension block 15 is filled in the gap except cabling, and suspension block is parallel
Quadrangle, triangle or irregular shape.Matching interval blind area by isolated ground 17 or driving cabling form, cabling it
Outer gap suspension block, suspension block are parallelogram, triangle or irregular shape.Positioned at the repetition electricity of same row
Induction electrode in pole unit is connected directly, to form multiple column induction electrodes；The repetition electrode unit with a line will be located at
In driving electrodes connected (not in figure on flexible circuit board (FPC) or printed circuit board (PCB) by Bonding pad
Show), to form multiple row driving electrodes.
Fig. 2 shows a complete repetition electrode unit.Wherein 21 be induction electrode, and 22 be driving electrodes.It is each heavy
Induction electrode 21 in telegram in reply pole unit, is made of the first strip shaped electric poles that multiple tops connect, and each first
The shape of shape electrode is vertically connected with such as multiple " mountain " words.And each driving electrodes 22 repeated in electrode unit, it is
It is linked together by the multiple second strip base parts complementary with multiple first strip shaped electric poles shapes.It is each to repeat electrode unit
In driving electrodes 22 there is a lead-out wire in lower section, every lead-out wire is directed towards the top-Bonding pad of touch screen.
It needing to stay the gap 0.2mm between induction electrode and driving electrodes, this gap fills suspension block, increase capacitance compensation, in order to avoid draw
Line broken string.
It is 3-4mm that design parameter requirement L1, which is driving Pitch width,.L2 is induction Pitch length, is TP VA section length
With the ratio of induction channels number.L3 is driving trace width, also referred to as dead zone, does not provide touch information theoretically herein, one
As be less than or equal to 2.2mm, this, closer to traditional mutual tolerance, touches that performance is better, and the position TX is different apart from smaller, and track lengths are not yet
Together, in order to meet channel impedance no more than limiting value, passage portion needs appropriate increase to draw line width, and cabling is longer, width
It is wider.If IT0 sheet resistance is smaller, cabling can be thinner, and dead zone area can reduce.L4 is the width of matching interval blind area
Degree is consistent with driving blind area width, can usually walk two driving lines herein, property-line is needed to be isolated.
Fig. 3 show pattern in TP SENSORAA peripheral wiring requirement, wherein in Fig. 3 A 31 be sensor edge line, 32
For peripheral ground wire, 34 be suspension block, and 31 be sensor edge line in Fig. 3 B, and 32 be peripheral ground wire, and 33 for driving cabling or press
Key cabling, 34 be suspension block, and 35 be isolated ground.
Due to the crack interference between TP and IXD, when backlight shines, clearly IT0 pattern, this hair can be seen
The bright IT0 pattern integrally arrangement wave-shaped, bending angle are between 10 °~20 ° of vertical direction left avertence.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
