As shown in figure 4, the first electrode pattern 21 has edge part 211, the edge part 211 and the corresponding company
The position of map interlinking case 24 is corresponding, and the side length L1 of the edge part 211 is less than or equal to the 1/ of the perimeter of the first electrode pattern 21
10, to further reduce the area in the gap between two neighboring first electrode pattern, user is further prevented to use
The shape for seeing pattern inside touch screen in the process, further improves display effect.
In one embodiment, as shown in figure 5, the two neighboring first electrode pattern 21 and the second electrode pattern
Have between 22 there are four the free cells 25 for being spaced apart from each other setting, there are third folders between the free cells 25 and horizontal line
Angle, namely favour horizontally arranged, the free cells 25 include four free segment 251-254 being arranged successively, described
251-254 is arranged with the corresponding first electrode pattern 21 and the interval of the second electrode pattern 22 respectively, the free segment
There are third angles between 251-254 and horizontal line 31.It is empty to respectively indicate the first free segment 251, second for dotted line 34,35 in Fig. 5
The extended line of not busy section 252.The angular range of the third angle includes between 0 degree to 45 degree, between 45 degree to 90 degree, 90 degree extremely
Between 135 degree, 135 degree it is at least a kind of between 180 degree, but do not include 0 °, 45 °, 90 °, 135 °, 180 °.Due to touching
Touch screen lower section pixel arrange on 0 °, 45 °, 90 °, 135 °, 180 ° of directions, when free cells angle be 0 °, 45 °, 90 °,
At 135 °, 180 °, the pixel quantity fallen into etching gap is most.When free cells avoid 0 °, 45 °, 90 °, 135 °, 180 °
When, the pixel quantity fallen into etching gap is reduced.Preferably, when free cells take 0 °, 45 °, 90 °, 135 °, 180 ° of centre
When being worth angle (i.e. 22.5 °, 67.5 °, 112.5 °, 157.5 °), the pixel quantity fallen into etching gap is minimum.Therefore work as each sky
When the free segment of not busy unit avoids above-mentioned angle, so that the pixel quantity fallen into etched gap is reduced, it in other words will be idle
The gap location of pixel is arranged in unit, to prevent user from seeing the shape inside touch screen, to preferably improve display effect
Fruit.Wherein etched gap includes the gap between first electrode pattern and second electrode pattern and free cells, may also include phase
Gap between adjacent sensing unit.When meeting above-mentioned relation for a1, a2 and third angle above, can further such that
It is mutually staggered between each free segment in each free cells, when each free segment mutually staggers, can be further improved display
Effect.
Wherein it is offset from each other between each free segment in the same free cells 25.In other words, adjacent described
The third angle of free segment is unequal.Such as the third angle of the third angle a3 of the free segment 251 and the free segment 252
A4 is unequal, and the third angle of the free segment 252 and the third angle of the free segment 253 are unequal.Namely adjacent institute
It states not parallel between free segment.In one embodiment, the third angle of four free segments is unequal.
It should be understood that the free cells 25 may include two, three or more than four free segments.
Wherein between the two neighboring free cells 25 symmetrically.
In conjunction with Fig. 5 and 4, in another embodiment, as shown in fig. 6, each free segment includes two first idle
Section 41 and two the second free segments 42, first free segment 41 are staggered with second free segment 42, and described first is empty
The angular range of third angle (sharp angle) between not busy section 41 and horizontal line 31 is between 45 degree to 90 degree, and described second is empty
Angle (sharp angle) range of third angle between not busy section 42 and the horizontal line 31 is Ye Jisuo between 0 degree to 45 degree
The angular range for stating the third angle between the first free segment and the horizontal line is 45 degree to 90 degree or 90 degree to 135 degree, institute
The angular range of the third angle between the second free segment and the horizontal line is stated as 0 degree to 45 degree or 135 degree to 180 degree.
The total length of two first free segments 41 in the free segment is equal to described two second free segments
42 total length.Wherein, two the first free segments 41 are parallel to each other, and two the second free segments 42 are parallel to each other.Certainly, free segment
It can also only include first free segment 41 and the second free segment 42, first free segment 41 is close to the connecting pattern at this time
32, for second free segment 42 far from the connecting pattern 32, it is idle that the length of first free segment 41 is equal to described second
The length of section 42.It should be understood that the free segment includes more than two first free segments 41 and the second free segment 42.It is above-mentioned
Scheme can make free cells arrange at polyline shaped, and then make free cells that the gap location of pixel be arranged in, to further subtract
The pixel quantity in etched gap is fallen into less, is further avoided user and is seen shape inside touch screen, preferably improves aobvious
Show effect.It, can be further such that in each free cells when meeting above-mentioned relation for a1, a2 and third angle above
Each free segment between mutually stagger, when each free segment mutually staggers, can be further improved display effect.
The first electrode pattern 21 or the material of the second electrode pattern 22 are tin indium oxide or indium zinc oxide.
The material of the connecting bridge 24 include tin indium oxide, indium zinc oxide, molybdenum, silver, titanium, copper, aluminium, molybdenum/aluminium/molybdenum and
Molybdenum/copper/molybdenum at least one.
The present invention also provides a kind of electronic devices comprising above-mentioned touch screen.
Touch screen and electronic device of the invention, by being set between adjacent first electrode pattern and second electrode pattern
Set free cells, the free cells include multiple free segments, the free cells respectively with the corresponding first electrode figure
Case and second electrode pattern interval setting, there are third angle between the free segment and horizontal line, and it is adjacent described
The third angle of free segment is unequal, so that free cells are arranged at polyline shaped, so that user be avoided to observe in use
Shape inside to touch screen improves the visuality and display effect of touch screen.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
