Detailed description of the invention
Below, specific embodiment of the utility model is described by way of example in detail.Should be understood that; embodiment of the present utility model is not limited to the example of act set forth below; those skilled in the art utilize principle of the present utility model or spirit can modify shown embodiment and modification; obtain the other embodiments that form is different; obviously, these embodiments both fall within the scope that this utility model is claimed.
Embodiment one:
Fig. 2 schematically shows the pattern of a touch sensing unit 10 in the touch sensible element according to an embodiment of the present utility model, it should be understood that be, the touch sensible element that the present embodiment provides can include the touch sensing unit 10 that multiple such same layer is arranged, in other words, a repetitive in the touch sensing unit 10 simply touch sensible element shown in Fig. 2.In the present embodiment, touch sensible element can include the touch sensing unit 10 that multiple same layer is arranged, touch sensing unit 10 includes at least one first touch sensible subelement 11, each first touch sensible subelement 11 includes the first electrode block array, first electrode block array of the first touch sensible subelement 11, the multiple same layer cascaded the electrode block arranged forms.
For purpose that is clear and that simplify, Fig. 2 simply schematically shows three the first touch sensible subelements 11.It should be appreciated that, single touch sensing unit 10 can include mutually insulated between the first touch sensible subelement 11 of at least one, and multiple first touch sensible subelement 11.As in figure 2 it is shown, the multiple first touch sensible subelements 11 in touch sensing unit 10 can have similar structure or a pattern, but the number of electrode block that each the first touch sensible subelement 11 is comprised can be different.Owing to, in the first electrode block array of each first touch sensible subelement, electrode block cascades with one another, so the first electrode block array in each first touch sensible subelement 11 can be formed actually and continual pattern.
Further, touch sensible element also includes electrically connecting with the first electrode block array, and the first wiring arranged with layer with the first electrode block array, is used for connecting driving chip.First wiring can be made up of the multiple electrode blocks electrically connected；Such as, three the first touch sensible subelements 11 can be connected with driving chip by the first wiring being made up of the electrode block of multiple series connection respectively.
In the present embodiment one, the touch sensible element including multiple touch sensing unit 10 can serve as self-capacitance pattern touch control electrode.As is known in the art, self-capacitance sensing detection method be by detection touch control electrode self electric capacity change (when finger touching touch screen time, the capacitance variations of touch control electrode self) detect touch location.As shown in Figure 2, first electrode block array of three the first touch sensible subelements 11 can receive, by the first wiring, driving signal Tx1, Tx2 and the Tx3 driven successively in sequential respectively as touch control electrode, first electrode block array of three the first touch sensible subelements 11 can also provide feedback signal respectively responsive to received driving signal to touch detection chip successively, touch detection chip by judging whether to occur touch-control to the analysis of feedback signal, thus realizes from holding touch control detection function.Or, when the first electrode block arrays of three of three the first touch sensible subelements 11 can also receive three identical driving signal Tx1, Tx2 and Tx3 as touch control electrode, and the first electrode block array combination of three the first touch sensible subelements 11 receives as an entirety and drives signal feedback signal.Those skilled in the art can derive according to this, and according to the precision required by touch-control, how the multiple first touch sensible subelement of unrestricted choice combines, and how to drive, and thus, this embodiment can be that the touch-control realizing self-capacitance pattern provides architecture basics.
Same, a touch sensing unit 20 in touch sensible element as shown in Figure 4, and the another kind of implementation of the first touch sensible subelement 21 structure that touch sensing unit 20 includes, it is possible to provide architecture basics for realizing the touch-control of self-capacitance pattern, do not repeating at this.
It should be noted that, when the first wiring is also made up of the electrode block electrically connected, in actual touch-control sensing, the change of its electric capacity there is also contribution to the sensing of touch-control, but it is connected with driving chip owing to the effect of the first wiring is only, the capacitance variations every time produced much smaller than the first electrode block array in the first upper capacitance variations produced of wiring during touch-control, those skilled in the art can pass through conventional technique means, ignore or identification is by the first upper capacitance variations produced of wiring, thus have no effect on the location of touch-control.
Embodiment two:
See Fig. 5, that schematically shows the touch sensible element according to another embodiment of the present utility model.It is on the basis of embodiment one, add the second touch sensible subelement 30, second touch sensible subelement includes the second electrode block array that the electrode block arranged by the multiple same layer cascaded forms, and the second touch sensible subelement and the first touch sensible subelement insulate.
In addition to structure same or similar with Fig. 2, increase the present embodiment structure of the second touch sensible subelement 30, can be to realize mutual capacitance touch-control to provide architecture basics.The most each first touch sensible subelement 11 can serve as receiving the drive electrode driving signal Tx1, Tx2, Tx3 from touch detection chip, and the second touch sensible subelement 30 can serve as providing the induction electrode of induced signal Rx to touch detection chip.As known to those skilled in the art, when a finger is touching the screen, the electric capacity between drive electrode and induction electrode can change, and can determine touch location by the change of the electric capacity between drive electrode and induction electrode.
In mutual capacitance sensing detection pattern, corresponding drive electrode in different touch sensing unit can receive identical driving signal simultaneously, such as, for the embodiment shown in Fig. 5, each electrode block array being used as drive electrode in different touch sensing unit can receive identical driving signal simultaneously, as such, it is possible to make the quantity of the pin (pin) of formed contact panel be reduced.
Fig. 6 schematically shows another implementation according to the present embodiment.Same, in this implementation, except being able to receive that three the first touch sensible subelements 21 driving signal, each touch sensing unit also includes that at least one can generate the second touch sensible subelement 30 of induced signal in response to driving signal.Different, in Fig. 6, the number of the electrode block that the first electrode block array of three the first touch sensible subelements 21 is comprised is different from shown in Fig. 5, and the electrode block number that in Fig. 6, the second electrode block array of the second touch sensible subelement 30 is comprised is different from shown in Fig. 5.
Further, the present embodiment is compared to embodiment one, and touch sensible element also includes the second wiring electrically connecting with described second electrode block array and arranging with layer with the second electrode block array, is used for connecting touch detection chip.Second wiring can be made up of the multiple electrode blocks electrically connected.
