It is described in detail below in conjunction with principle of the Fig. 1 to Fig. 3 to the embodiment of the present invention.Wherein, Fig. 1 is a kind of mutual capacitance
The structural schematic diagram of formula touch panel, Fig. 2 are the partial enlargement diagram in Fig. 1 at dotted line frame A, and Fig. 3 is in structure shown in Fig. 1
One of touch-driven electrode and a touch-control sensing electrode schematic diagram.
As depicted in figs. 1 and 2, specifically, in above-mentioned touch panel provided in an embodiment of the present invention, what is be arranged in array is more
A touch control electrode 10 constitutes the touch-driven electrode 101, Yi Jiyan extended along first direction (direction shown by arrow Y in such as figure)
The touch-control sensing electrode 102 that second direction (direction shown by arrow X in such as figure) extends；First direction Y and second direction X are mutual
Intersect；
Touch-driven electrode 101 and touch-control sensing electrode 102 all have through-hole.
As shown in Figure 1, each touch-driven electrode 101 and each touch-control sensing electrode 102 are examined by conducting wire 30 and touch-control respectively
It surveys chip 40 to connect, referring concurrently to Fig. 3, during touch control detection, from touch control detection chip 40 to each touch-driven electrode 101
Touch-control is provided and drives (Tx) signal, such as can be square-wave signal, and passes through the constantly detection touch-control sense of touch-control sensing electrode 102
(Rx) signal is answered, to judge the position of touch of touch panel.It is carried out so that first direction Y is vertical with second direction X as an example in Fig. 1
Signal, in the specific implementation, the angle between first direction Y and second direction X may be other angles, not limit herein
It is fixed.
In the specific implementation, referring to Figures 1 and 2, above-mentioned touch-driven electrode 101 and above-mentioned touch-control sensing electrode 102 can
To be in same film layer, connecting bridge 50 is equipped at the position that touch-driven electrode 101 and touch-control sensing electrode 102 are intersected, and
102 mutually insulated of touch-driven electrode 101 and touch-control sensing electrode at position where connecting bridge 50, touch-driven electrode 101
In each touch control electrode 10 connected by being located at the conducting wire of same layer, each touch control electrode 10 in touch-control sensing electrode 102 passes through company
It connects bridging to connect, for ease of description the positional relationship and size relationship between touch-driven electrode 101 and touch-control sensing electrode 102
Deng the embodiment of the present invention is illustrated with the structure that touch-driven electrode and touch-control sensing electrode are located at same film layer, specific
When implementation, touch-driven electrode and touch-control sensing electrode can also be located at two film layers of mutually insulated, not limit herein
It is fixed.
As shown in figure 3, there is parasitic capacitance Cp over the ground between touch-driven electrode 101 and the earth, the parasitic capacitance is by electricity
Hold formula:It determines, wherein εrAnd ε0Indicate that dielectric constant, s indicate to constitute the phase between two electrodes of capacitor
To area, s indicates that the effective area of touch control electrode, d indicate to constitute between two electrodes of capacitor in embodiments of the present invention
Distance.In the embodiment of the present invention, since touch control electrode has the through-hole through film layer where touch control electrode, as shown in Figures 1 to 3,
By taking touch-driven electrode 101 and touch-control sensing electrode 102 all have through-hole 20 as an example, thus the effective area s of touch control electrode subtracts
It is small, and permittivity εrAnd ε0, and distance d is constant, thus the Cp of parasitic capacitance over the ground of touch control electrode reduces, shared by through-hole 20
Area it is bigger, then the effective area of touch control electrode is smaller, so that the degree that parasitic capacitance Cp reduces over the ground is bigger, specific real
Shi Shi, can be by the size and number of setting through-hole 20, to control the degree that the effective area of touch control electrode reduces.
Also, as shown in figure 3, at the position of connecting bridge 50, or in touch-driven electrode 101 and touch-control sensing electrode

Formula are as follows:Wherein,Indicate the sheet resistance of touch control electrode, it is constant for the touch control electrode sheet resistance of identical material,
H indicates cornerwise effective length of diamond shape, and since through-hole is arranged in touch control electrode, the effective length h of prismatic diagonal subtracts
Small, a is the width at connecting bridge, and since connecting bridge itself is relatively narrow, through-hole is generally arranged not at connecting bridge, thus a is kept not
Become, k indicates effective slope of diamond shape, and since through-hole is arranged in touch control electrode, thus effectively slope k reduces relatively, all due to h and k
A degree of reduction is had, thus the variation degree of impedance R will not be very big, ordinary circumstance can slightly increase.
To sum up, since touch control electrode has through-hole, reduce the effective area of touch control electrode, thus make pair of touch control electrode
Ground parasitic capacitance Cp can reduce, and the impedance R of touch control electrode slightly increases, and the RC charging time can be made to reduce on the whole, to drop
The attenuation degree of low touching signals (Tx or Rx) improves the scan frequency and report point rate of touch drive signal (Tx), to improve
Touch-control sensitivity.Further, since the attenuation degree of reduction touching signals may be implemented by the way that through-hole is arranged, thus no longer need to pass through
Increase the mode of the thickness of touch control electrode to change the sheet resistance of touch control electrode, moreover, can drop just because of by the way that through-hole is arranged

Multiple through-holes 20 may be uniformly distributed in interior zone, can be with for example, when the through-hole in touch control electrode is more
It is distributed in through-hole uniformly in touch control electrode as far as possible, to keep the stress of each position in touch control electrode relatively uniform, guarantees
The touch-control effect of touch control electrode.
Alternatively, multiple through-holes are uniformly distributed in interior zone and fringe region.For example, when the number of openings in touch control electrode
When less, through-hole can be concentrated on to the interior zone of touch control electrode, thus guarantee the uniform force of each touch control electrode, thus
Will not the touch-control effect to touch control electrode have an impact.
