Specific embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to
Convenient for description, part relevant to related invention is illustrated only in attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 shows the structural schematic diagram of one embodiment of the touch-control display panel according to the application.As shown in Figure 1,
The touch-control display panel 100 of the present embodiment includes: along first direction D1 extension, M the first touch-controls that D2 is arranged in a second direction
Electrode 101 and in a second direction D2 extend, along N number of second touch control electrode 102 of first direction D1 arrangement.Wherein, M, N are positive
Integer.Also, orthographic projection and each second touch-control electricity of each first touch control electrode 101 to each 102 place plane of second touch control electrode
Pole 102 is at least partly overlapped.As shown in Figure 1, positive throwing of first touch control electrode 101 to 102 place plane of second touch control electrode
Shadow has lap with each second touch control electrode 102.It is understood that above-mentioned first touch control electrode 101 can be touching
Control driving electrodes, or touch-control sensing electrode.When the first touch control electrode 101 is touch-driven electrode, the second touch-control electricity
Pole 102 is touch-control sensing electrode.
In above-mentioned M the first touch control electrodes 101, the first touch control electrode of every two 101 is electrically connected to each other, if i-th first
Touch control electrode is electrically connected with k-th of first touch control electrodes, then the first touching of (i-1)-th the first touch control electrode and i+1 is arranged
Control electrode meets the following conditions: when the first touch control electrode of i+1 is electrically connected with -1 the first touch control electrode of kth+1 or kth,
In (i-1)-th the first touch control electrode and above-mentioned M the first touch control electrodes in addition to -1 kth+1, kth the first touch control electrode one
A first touch control electrode electrical connection；When (i-1)-th the first touch control electrode is electrically connected with -1 the first touch control electrode of kth+1 or kth
When, in i+1 the first touch control electrode and above-mentioned M the first touch control electrodes in addition to -1 kth+1, kth the first touch control electrode
First touch control electrode electrical connection.Wherein, i, k meet: 2≤i≤M-3,4≤k≤M-1, k-i >=2.
That is, working as, i-th of first touch control electrodes are electrically connected with k-th of first touch control electrodes and i+1 first is touched
Control electrode is with -1 the first touch control electrode of kth+1 or kth when being electrically connected, and (i-1)-th the first touch control electrode cannot be with kth+1 or the
K-1 the first touch control electrode electrical connections.When i-th of first touch control electrodes are electrically connected and (i-1)-th with k-th of first touch control electrodes
When first touch control electrode is electrically connected with -1 the first touch control electrode of kth+1 or kth, the first touch control electrode of i+1 cannot be with kth
+ 1 or kth -1 the first touch control electrode electrical connection.
This is because i-th of first touch control electrodes can produce when finger or stylus i-th of first touch control electrodes of touch-control
Raw charge inducing amount.Exist in view of finger or stylus are generally greater than first touch control electrode in the width of second direction D2
The width of second direction D2, in this way, touch-control is equally understood to i+1 the first touch control electrode and i-th-in finger or the edge of stylus

The value for the charge inducing amount that a first touch control electrode generates is identical.As the first touch control electrode of i+1 and kth+1 or kth -1
When an electrical connection in the first touch control electrode, in -1 the first touch control electrode of kth+1 or kth with i+1 the first touch-control electricity
The charge inducing that the value and the first touch control electrode of i+1 of charge inducing amount existing for first touch control electrode of pole electrical connection generate
The value of amount is identical.If another in (i-1)-th the first touch control electrode and -1 the first touch control electrode of kth+1 or kth at this time
Electrical connection, then the first touch-control electricity being electrically connected in -1 the first touch control electrode of kth+1 or kth with (i-1)-th the first touch control electrode
The value of extremely existing charge inducing amount is identical as the value of charge inducing amount that (i-1)-th the first touch control electrode generates, just can not be true
Fixed true position of touch.

One touch control electrode is electrically connected with the 4th the first touch control electrode, then the 3rd the first touch control electrode cannot be with the 6th the first touch-control electricity
Pole electrical connection.In Fig. 1, the 3rd the first touch control electrode is electrically connected with M-1 the first touch control electrodes, the 6th the first touch control electrode
It is electrically connected with the first touch control electrode of m-th.
It is understood that when any of the 1st the first touch control electrode and 3~m-th, first touch control electrode the
When one touch control electrode is electrically connected, it is only necessary to which the first touch control electrode that the 2nd the first touch control electrode is electrically connected and the 1st the are set
The first touch control electrode that one touch control electrode is electrically connected is non-conterminous.Similarly, when the first touch control electrode of m-th and the 1st~the
When the first touch control electrode electrical connection of any of M-2 the first touch control electrodes, it is only necessary to which M-1 the first touch control electrodes are set
The first touch control electrode that the first touch control electrode being electrically connected is electrically connected with the first touch control electrode of m-th is non-conterminous.

Control electrode is electrically connected two-by-two, and above-mentioned first touch control electrode can be touch-driven electrode, or touch-control sensing electrode.Setting
I-th of first touch control electrodes are electrically connected with k-th of first touch control electrodes, meanwhile, when the first touch control electrode of i+1 and kth+1
Or when kth -1 the first touch control electrode electrical connection, in (i-1)-th the first touch control electrode and M the first touch control electrodes except kth+1,
First touch control electrode electrical connection except -1 the first touch control electrode of kth；When (i-1)-th the first touch control electrode and kth+1
Or when kth -1 the first touch control electrode electrical connection, in the first touch control electrode of i+1 and M the first touch control electrodes except kth+1,
First touch control electrode electrical connection except -1 the first touch control electrode of kth.In such manner, it is possible to pass through each first touch control electrode
