As shown in figure 13, Figure 13 be a kind of traditional contact panel 20 structural representation (clear for Figure 13, the most right
BM carries out shade sign), contact panel 20 includes: underlay substrate；Underlay substrate is formed BM, BM and is positioned at underlay substrate limit
The annular region of edge；It is formed on the underlay substrate of BM and is formed with transparent conductive pattern 201, the outside of transparent conductive pattern 201
There is overlapping region in the inward flange of edge and BM, transparent conductive pattern 201 includes: the touch of a plurality of horizontally set drives line Tx with many
The thread touch sensor Rx that bar is longitudinally disposed, and multiple vacant piece, the Tx of a plurality of horizontally set and a plurality of longitudinally disposed Rx phase
Insulation mutually, and form multiple cross structure.Each cross structure and be positioned at multiple skies in vacant district of cross structure corner
Put block one touch control unit of composition；In transparent conductive pattern 201, the structure of each touch control unit L0 is identical, in correlation technique, logical
Touch control unit is often referred to as Pixel (English: pixel), and the transparent conductive pattern 201 of Figure 13 is actually by same Pixel battle array
Row.Example, the structure of each touch control unit L0 is referred to structure L1 of the touch control unit shown in Fig. 2.
Therefore, the touch control unit that the touch control unit of offer and Figure 13 in Fig. 1-1, Fig. 1-2 or Fig. 3 to Figure 10 provide is carried out
Relatively, it can be clearly seen that, in the contact panel 10 that this utility model embodiment provides, BM is overlapping with transparent conductive pattern
In region, the distribution density of vacant piece is significantly greater than the distribution density of traditional contact panel 20.That is to say, in unit are,
The number of vacant piece in overlapping region is more, and the area of each vacant piece is relatively small, short with vacant piece of generation at Tx or Rx
Lu Shi, owing to, in BM district, the area of vacant piece is less, the impact on the size of Tx and Rx electric capacity is more weak, thus effectively reduces
Impact on the touch effect of contact panel.Further, in this utility model embodiment, the transparent conductive pattern of change non-display
The structure of vacant piece on region, does not affect the display of its VA.
In traditional contact panel 20, in order to improve the optical effect of VA, the gap of each graphic element adjacent in VA
Width is usually 30um (micron), in order to ensure the integrally-built homogeneity of contact panel, and all of figure on transparent conductive pattern
The gap width of shape unit is disposed as the width fixed, and that is to say 30um.In this utility model embodiment, graphic element is permissible
For constituting the minimum independent drawing of transparent conductive pattern, such as vacant piece, Tx etc..
But, inventor through repeatedly it is experimentally confirmed that in the overlapping region of transparent conductive pattern and BM, two adjacent
The gap width of graphic element the biggest, the probability producing short circuit is the lowest, therefore, in this utility model embodiment, is positioned at this
The gap width of the graphic element that any two in overlapping region is adjacent can be more than 30um.So can effectively reduce overlay region
The probability of territory short circuit.
But, in actual application, when the gap width of BM district graphic element increases, the mutual capacitance of node of single touch control unit
Can increase, (be greater than 100um) when gap width is excessive, the increase of node capacitor value is too much, the node electricity in such BM district
Capacitance generally node capacitor value than VA is much larger, causes the lack of homogeneity of transparent conductive pattern, affects touch panel edge district
The touch performance in territory.Drive integrated circult owing to being connected respectively with Tx, Rx is (English: Integrated Circuit；It is called for short:
IC) upper limit of the gap width that chip can be supported by is that (that is to say, when gap width is within 100um, node is electric for 100um
Capacitance is in the tolerance interval of driving IC chip, now little to the touch performance impact in touch panel edge region), in order to
Ensure effective driving of driving IC chip, it is preferred that as shown in figure 14, the contact panel 10 that this utility model embodiment is provided
In, the gap width of the graphic element that any two in overlapping region is adjacent is 100um.The gap width of VA can be still
30um。
During it should be noted that conductive surface has electric charge accumulation, charge density is relevant with the shape of conductive surface, due to point
Sharp place curvature is big, and electric lines of force is intensive, and charge density is little at mild position, maximum at the position of point.Therefore, the most advanced and sophisticated appearance of conductor
Easily assembling electric charge, after charge density reaches a certain amount value, the electric field that electric charge produces can be very big, is easy for there will be tip and puts
Electrical phenomena.
In this utility model embodiment, in order to avoid the generation of point discharge phenomenon, arbitrary figure in transparent conductive pattern
The corner of unit is fillet, and fillet is relative to sharp-pointed acute angle, and its curvature is less, it is achieved seamlessly transitting of figure, it is possible to subtract
Few accumulation, it is to avoid the generation of point discharge phenomenon.
In sum, the contact panel that this utility model embodiment provides, transparent conductive pattern exists and is positioned at overlay region
The distribution density of vacant piece in territory is more than the distribution density of vacant piece be positioned in VA, owing to being positioned at the sky in the W of overlapping region
The distribution density putting block is relatively big, that is to say, in unit are, the number of vacant piece in overlapping region is more, overlapping region
In the area of each vacant piece relatively small, when Tx or Rx is short-circuited with vacant piece, due in BM district, the face of vacant piece
Long-pending less, the impact on the size of Tx and Rx electric capacity is more weak, thus effectively reduces the impact of the touch effect on contact panel.
This utility model embodiment provides the manufacture method of a kind of contact panel, is used for manufacturing the above-mentioned enforcement of this utility model
The contact panel 10 that example provides, as shown in figure 15, this manufacture method includes:
Step 301, on underlay substrate formed BM, this BM be positioned at the annular region at underlay substrate edge.

Thread touch sensor Rx, and multiple vacant piece, the Tx of a plurality of horizontally set and a plurality of longitudinally disposed Rx mutually insulated；
Wherein, the gap width of the graphic element that any two in overlapping region is adjacent is more than 30um.
Optionally, the gap width of the graphic element that any two in overlapping region is adjacent is 100um.Figure 18 with
Indicated as a example by 100um.
In traditional contact panel 20, as shown in figure 13, in order to improve the optical effect of VA, each figure adjacent in VA
The gap width of unit is usually 30um (micron), in order to ensure the integrally-built homogeneity of contact panel, transparent conductive pattern
The gap width of upper all of graphic element is disposed as the width fixed, and that is to say 30um.
But, inventor through repeatedly it is experimentally confirmed that in the overlapping region of transparent conductive pattern and BM, two adjacent
The gap width of graphic element the biggest, the probability producing short circuit is the lowest, therefore, in this utility model embodiment, is positioned at this
The gap width of the graphic element that any two in overlapping region is adjacent can be more than 30um.So can effectively reduce overlay region
The probability of territory short circuit.
But, in actual application, when the gap width of BM district graphic element increases, the mutual capacitance of node of single touch control unit
Can increase, (be greater than 100um) when gap width is excessive, the increase of node capacitor value is too much, the node electricity in such BM district
Capacitance generally node capacitor value than VA is much larger, causes the lack of homogeneity of transparent conductive pattern, affects touch panel edge district
The touch performance in territory.Drive integrated circult owing to being connected respectively with Tx, Rx is (English: Integrated Circuit；It is called for short:
IC) upper limit of the gap width that chip can be supported by is that (that is to say, when gap width is within 100um, node is electric for 100um
Capacitance is in the tolerance interval of driving IC chip, now little to the touch performance impact in touch panel edge region), in order to
Ensure effective driving of driving IC chip, it is preferred that as shown in figure 14, the contact panel 10 that this utility model embodiment is provided
In, the gap width of the graphic element that any two in overlapping region is adjacent is 100um.The gap width of VA can be still
30um。
During it should be noted that conductive surface has electric charge accumulation, charge density is relevant with the shape of conductive surface, due to point
Sharp place curvature is big, and electric lines of force is intensive, and charge density is little at mild position, maximum at the position of point.Therefore, the most advanced and sophisticated appearance of conductor
Easily assembling electric charge, after charge density reaches a certain amount value, the electric field that electric charge produces can be very big, is easy for there will be tip and puts
Electrical phenomena.
In sum, the contact panel that this utility model embodiment provides, owing to any two in overlapping region is adjacent
Graphic element gap width more than 30um effectively reduce overlapping region short circuit probability, and, adjacent in any two
When the gap width of graphic element is 100um, it is possible on the premise of the effectively driving ensureing driving IC chip, it is achieved subtract as far as possible
The probability of few overlapping region short circuit.
It should be noted that " adjacent " described in this utility model embodiment refers to that two figures pass through gap insulation,
But suffer recently.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
