From unlike the embodiment shown in Fig. 2, in the present embodiment, driving in scanning element 302 to include
VSR0, and VSR0 sends scanning signal to TX1 and TXN respectively by two unidirectional conducting switch units 303.In touch detection
When, scanning signal first propagates to VSR0, then propagates to VSR1, VSR2VSRN-1 successively.So make TX1 with other first
As touch control electrode 301, twice sweep signal can be received, such that it is able to effectively ensure that the touch-control of TX1 left borders is examined
Survey precision.Alternatively, in order to ensure the touch control detection precision of TXN right side boundaries, VSRN-1 can be electrically connected (in figure with VSR0
It is not shown).That is, after scanning signal incoming VSR0 again, a scan period just terminates.It should be noted that
Scanning signal can only be transmitted to VSR0 by VSRN-1, it is impossible to be transmitted to VSRN-1 by VSR0.
As shown in figure 4, the array base palte of the application include multiple first touch control electrodes 401, i.e. TX1, TX2, TX3, TX4,
TX5、TX6、TX7、TX8···.Wherein, TX1, TX2 and TX4 are the first touch control electrode group；TX3, TX4 and TX6 are touched for second
Control electrode group；TX5, TX6 and TX8 are the 3rd touch control electrode group etc..That is, each touch control electrode group is except comprising at least
Outside two the first adjacent touch control electrodes, multiple non-conterminous first touch control electrodes can also be included.And two neighboring touch-control
Electrode group includes a first shared touch control electrode.
In the present embodiment, it is each to drive scanning element 402 to be sequentially connected electrically, and each drives scanning element 402 to
Individual touch control electrode group sends scanning signal.Figure 4, it is seen that VSR1 sends scanning signal to TX1, TX2 and TX4；VSR2
Scanning signal is sent to TX3, TX4 and TX6；VSR3 to TX5, TX6 and TX8 send scanning signal etc..Further, since first touches
The first shared touch control electrode 401 that control electrode group and second touch control electrode group are included is TX4, so VSR1 passes through two poles
Pipe (unidirectional conducting switch unit) 403 is electrically connected with TX4, and VSR2 is also electrically connected by another diode 403 with TX4.Equally
Ground, because the first shared touch control electrode 401 that second touch control electrode group and the 3rd touch control electrode group are included is TX3, so
VSR2 is electrically connected by a diode 403 with TX3, and VSR3 is also electrically connected by another diode 403 with TX3.Other are touched
Electrically connect with corresponding the first shared touch control electrode 401 after the same method between control electrode group.
Compared with the embodiment shown in Fig. 3, each the touch control electrode group in the present embodiment includes more first touch-controls electricity

502 to touch control electrode groups of unit send scanning signal.Meanwhile, each first shared touch control electrode 501 is each with what it was located
Each driving scanning element 502 corresponding to touch control electrode group, is electrically connected respectively by a unidirectional conducting switch unit 503.
From unlike the embodiment shown in Fig. 4, between each first touch control electrode 501 in each touch control electrode group two-by-two
It is adjacent.That is, each first touch control electrode 501 in each touch control electrode group is arranged in order.As shown in figure 5, the first touch-control
Electrode group includes TX1, TX2 and TX3；Second touch control electrode group includes TX3, TX4 and TX5；3rd touch control electrode group comprising TX5,
TX6 and TX7, by that analogy.
Compared with the embodiment shown in Fig. 4, in each the touch control electrode group in the present embodiment two between the first touch control electrode
Two is adjacent so that each drives the driving scope of scanning element continuous, is conducive to improving the precision of touch control detection.
With further reference to Fig. 6, the array base palte of the application includes multiple first touch control electrodes 601, i.e. TX1, TX2, TX3,
TX4、TX5、TX6···.Wherein, TX1, TX2, TX3 and TX4 are the first touch control electrode group；TX2, TX3, TX4 and TX5 are the
Two touch control electrode groups；TX3, TX4, TX5 and TX6 are the 3rd touch control electrode group etc..That is, each touch control electrode group is included

VSR2 to TX2, TX3, TX4 and TX5 send scanning signal；VSR3 to TX3, TX4, TX5 and TX6 send scanning signal etc..This
Outward, because the first touch control electrode of shared three 601 that the first touch control electrode group and second touch control electrode group are included is respectively
TX2, TX3 and TX4, so VSR1 is electric with TX2, TX3 and TX4 respectively by three diode (unidirectional conducting switch units) 603
Connection；VSR2 is also electrically connected with TX2, TX3 and TX4 respectively by the other three diode 603.Similarly, second touch control electrode
The first touch control electrode of shared three 601 that group and the 3rd touch control electrode group are included is respectively TX3, TX4 and TX5, due to VSR2
Pass through two diodes 603 to electrically connect with TX3 and TX4 respectively, so VSR2 is electric with TX5 by a diode 603 again
Connection；And VSR3 is also electrically connected with TX3, TX4 and TX5 respectively by the other three diode 603.From fig. 6 it can be seen that this
When the first touch control electrode group and the 3rd touch control electrode group also contains two the first shared touch control electrodes 601 (TX3 and TX4).
Meanwhile, VSR1 and VSR3 has also been electrically connected respectively by diode 603 with TX3 and TX4.Between other touch control electrode groups according to
Same method is electrically connected with corresponding the first shared touch control electrode 601.
Compared with the embodiment shown in Fig. 5, the two neighboring touch control electrode group in the present embodiment is touched comprising first for sharing
The more of electrode is controlled, can so increase the overlapping area of the driving scope of two neighboring driving scanning element, or even can
So that non-conterminous each driving overlapping ranges driven between scanning element, so as to effectively improve touch control detection precision.Additionally,
The quantity of the first touch control electrode that each touch control electrode group is included also accordingly increases, and can also so effectively improve scanning effect
Rate, and the quantity for driving scanning element and its wiring can be reduced to a certain extent, it is equally beneficial for the narrow frame of lower frame
Design.
