As shown in figure 5, that schematically shows a touch control electrode 510 and corresponding multiple display pixels 541~
544.In display pixel 541, touch control electrode 510 includes two the first slits 511,512.Along the first slit 511,512
Extending direction, touch control electrode have been divided to form three first electrodes 521,522,523.
It should be noted that herein, the meaning of " segmentation " word should not narrowly be interpreted as making each first electrode
It mutually " insulate ", and can be understood as that there is wider intension than " insulation ".For example, in application scenes, although one
Touch control electrode in a display pixel forms multiple first electrode by multiple first slits " segmentation ", each first electrode it
Between be still electrically connected to each other.And in other application scenarios, the touch control electrode in a display pixel can be by multiple first
Slit " segmentation " forms first electrode of multiple mutually insulateds, these first electrode for example can respectively with touch-control electricity
Extremely corresponding touching signals line electrical connection, so that it is equal to realize that each first electrode for belonging to a touch control electrode has
Current potential.
In addition, although each first slit in Fig. 5, in two the first slits 511 and 512 and display pixel 542~544
It is of similar shape and extending direction, but this is only schematical.It in practical applications, can be according to the need of application scenarios
The shape, quantity and extending direction of first slit be set, the scheme of the application to this with no restriction.
In other optional embodiments, touch control electrode can be between substrate and pixel electrode.In other words,
In these optional implementations, when making the integrated touch-control display panel of the present embodiment, touch control electrode can be prior to picture
Plain electrode fabrication is completed, so that touch control electrode is in than each pixel electrode in the integrated touch-control display panel being ultimately produced
Closer to the position of substrate.In these optional embodiments, pixel electrode can have at least one second slit.One
In a display pixel, pixel electrode can be divided by the second slit shapes at least one second electrode.In these optional implementations
In mode, structure and shape as shown in Figure 5 for example also can have by the pixel electrode after the segmentation of the second slit.However, picture
Shape and structure of plain electrode are also schematical.It will be appreciated by those skilled in the art that in a display pixel, second
Shape, quantity and the extending direction of slit can be equally arranged according to practical application, the scheme of the application to this with no restriction.
With continued reference to Fig. 4.In some alternative embodiments, the extending direction of touching signals line 431~434 can be with
The extending direction of data line D1~D4 is identical.In application scenes, for example, data line D1~D4 can be considered as straightway.
In these application scenarios, touching signals line 431~434 is identical as data line D1~D4 extending direction for example to be can be understood as respectively
Touching signals line 431~434 and pieces of data line D1~D4 is parallel to each other.In other application scenarios, due to showing picture
The shape of element and/or the demand of array arrangement mode, data line can be considered as broken line.In these application scenarios, touching signals
Line 431~434 is identical as data line D1~D4 extending direction for example it is to be understood that touching signals line 431~434 is also folding
Line, and each broken line piecewise-parallel of each broken line of touching signals line 431~434 and data line D1~D4.Alternatively, although touching
Control that signal wire 431~434 and data line D1~D4 be not parallel or piecewise-parallel, but the whole extending direction of the two is identical
's.
In these optional embodiments, a plurality of touching signals line 431~434 plane where substrate has first just
Projection.Data line D1~D4 plane where substrate has the second orthographic projection.Each first orthographic projection and second orthographic projection
It is at least partly overlapping.
Herein, the first orthographic projection, the second orthographic projection can be understood as touching signals line and data line along perpendicular to substrate
Projection of 410 direction to substrate 410.
Since each touching signals line 431~434 is between two adjacent display pixels, and under normal conditions, data
Line D1~D4 also is located between two adjacent display pixels.By the way that each touching signals line 431~434 and each data line D1 is arranged
The cabling of~D4 can make adjacent two so that each first orthographic projection and second orthographic projection are at least partly overlapping
Spacing between display pixel is smaller, thus more display pixels that can arrange on unit area, conducive to the reality of high PPI
It is existing, and then promote display effect.
In some alternative embodiments, touching signals line and data line can have structure and phase as shown in FIG. 6
To positional relationship.Specifically, as shown in fig. 6, touching signals line 620 can between two neighboring display pixel 611 and 612
With with third slit 621 (namely hollow-out part in Fig. 6 in touching signals line 620), third slit 621 is put down where substrate
Face has third orthographic projection.Third orthographic projection and the second orthographic projection have at least partly overlapping.In other words, data line 630 exists
Orthographic projection on substrate is at least partly overlapped with orthographic projection of the third slit 621 on substrate.
Further, in these optional embodiments, on the direction vertical with the extending direction of data line, third
Orthographic projection can cover the second orthographic projection.In other words, on the direction perpendicular to 630 extending direction of data line, third slit
621 width is greater than the width of data line 630, so that in the width direction, the orthographic projection of data line 630 can fall into the just
In the orthographic projection of three slits 621.
So, third slit 621 is opened up by the position corresponding with data line 630 in touching signals line 620, it can
So that the parasitic capacitance formed between the film layer where data line 630 and the film layer where touching signals line 630 can be into one
Step ground reduces.
In some alternative embodiments, between two adjacent display pixels, touching signals line can be narrow by third
Seam is divided into two third branch electrodes, and two third branch electrodes serve as the public electrode of its immediate display pixel.
With continued reference to Fig. 6, touching signals line 620 is divided into left and right two parts (i.e. two third branch by third slit 621
Electrode), the part in left side may be used as the public electrode of display pixel 621, and provide public affairs to display pixel 621 during display
Signal altogether.Similarly, the part on right side may be used as the public electrode of display pixel 622, and to display pixel during display
622 provide common signal.

Fig. 7 A is shown in the integrated touch-control display panel of the present embodiment, the schematic cloth of touch control electrode and touching signals line
Office's relationship.In Fig. 7 A, in order to protrude the layout relationship of touch control electrode and touching signals line, have ignored to each touch control electrode and touch-control
The description of the shape of signal wire itself.
Each dotted line frame in Fig. 7 A represents a block-like touch control electrode, and touch-control electricity is schematically shown in Fig. 7 A
The array arrangement of extremely 3 rows 3 column.By taking the touch control electrode 710 that the 3rd row the 1st in Fig. 7 arranges as an example (i.e. m=3, n=1), touch-control electricity
Pole 710 forms three (m) sub-electrodes, i.e. sub-electrode 711, son by two (m-1 item) touching signals line 721 and 722 segmentations
Electrode 712 and sub-electrode 713.
Wherein, touching signals line 721 is the touching signals line connecting with the touch control electrode that the 2nd row the 1st arranges, touching signals line
722 be the touching signals line connecting with the touch control electrode that the 3rd row the 1st arranges.
Similarly, then by taking the touch control electrode 730 that the 3rd row the 2nd in Fig. 7 A arranges as an example (i.e. m=3, n=2), the touch control electrode
730 form three sub-electrodes, i.e. sub-electrode 731,732 and of sub-electrode by touching signals line 741 and the segmentation of touching signals line 742
Sub-electrode 733.Wherein, touching signals line 741 is the touching signals line connecting with the touch control electrode that the 2nd row the 2nd arranges, touching signals

It will be understood by those skilled in the art that touch control electrode is divided the quantity for the sub-electrode to be formed by touching signals line, with
The quantity of touching signals line is related.For example, when each touch control electrode is electrically connected with two touching signals lines, what m row n-th arranged
Touch control electrode will be divided into 2m sub-electrode.And so on, when each touch control electrode is electrically connected with k touching signals line,
The touch control electrode that m row n-th arranges will be divided into k × m sub-electrode.Those skilled in the art are obtaining reality as shown in Figure 7
On the basis of the technical solution of integrated touch-control display panel for applying example, touch control electrode can be set to according to concrete application scene
