Also namely, at signal transfer direction, the first branch 114a and the second branch 124a is irregular figure, relative to regular figure (as shown in Figure 6), when needing to press equal area, the length of pressing is longer, thus can improve the precision of false-touch prevention further.
Further, in the present embodiment, shape and the size of the first function part 114 and the second function part 124 are identical, and the first function part 114 and the second function part 124 1 corresponding sides close to each other.Also namely the first function part 114 and the second function part 124 are congruent figures, and the arrangement of the first function part 114 and the second function part 124 meets, and one group corresponding sides are close to each other.
Further, in the present embodiment, the first induction pattern 110 respond to pattern 120 shape with second and size identical, rectangular triangle, the first hypotenuse responding to pattern 110 responds to the hypotenuse of pattern 120 near second.Also namely the first function part 114 only includes a first branch 114a, and the second function part 124 only includes a second branch 124a.
Further, in the present embodiment, the area of the first induction pattern 110 is S, and when the first function part 114 is pressed against S/3 ± 5%S area, the second function part 124 can be pressed against S/3 ± 5%S area.Thus make the size distribution of the first anti-tactile portion 112 and the first function part 114 more reasonable.
As shown in Figure 7, in other embodiments, the number of the first branch 114a and the number sum of the second branch 124a are more than or equal to 3, and the first branch 114a and the second branch 124a is staggered.
In the figure 7, along on the anti-direction of touching portion 112 of the first function part 114 to the first, each (all) first branch 114a both sides between spacing continuity become large gradually.Along on the anti-direction of touching portion 122 of the second function part 124 to the second, each (all) second branch 124a both sides between spacing continuity become large gradually.Further, in the figure 7, first induction pattern 110 respond to pattern 120 shape with second and size identical.
In his embodiment, as shown in Figure 8, along on the anti-direction of touching portion 112 of the first function part 114 to the first, each (owning) first branch 114a both sides between spacing continuity become large gradually.On the direction along the second anti-tactile portion 122 of function part 124 to the second, the spacing continuity between the both sides of part second branch 124a becomes large gradually, and the spacing discontinuity between the both sides of part second branch 124a becomes large gradually.Also namely the first induction pattern 110 and second to respond to pattern 120 shape not identical.
As shown in Figure 3, lead-in wire 24 comprises the first lead-in wire 24a and second lead-in wire 24b.One end of first lead-in wire 24a is electrically connected away from the side of functional area 200 with the first anti-tactile portion 112, and the other end is used for chip electrical and connects.One end of second lead-in wire 24b is electrically connected away from the side of functional area 200 with the second anti-tactile portion 122, and the other end is used for chip electrical and connects.
In the present embodiment, also provide a kind of false-touch prevention method of touch-screen, described method comprises, and when human finger is only pressed into the area of the first function part more than 50%, and when being pressed into the second function part more than 50% area, described touch controlled key is triggered; When human finger be pressed into first and second function part respective area more than 50% while, be also pressed into first and second and anti-touch portion or first and second anti-one of them of portion touched, then described touch controlled key is not triggered.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this instructions is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
