Signal is retouched, the scanning signal can be transmitted through drives line to the pressure-sensitive electroconductive resin of corresponding connection.For example, give each drives line
The scanning voltage signal of offer can be 0~15V so that be connected to the leakage current of the display thin film transistor (TFT) of the drives line compared with
It is low, it is off, does not influence the dispaly state of corresponding sub-pixel.Occur if acted without external touch, because this is public
The current potential of voltage signal is essentially certain value, and the electric current for flowing through pressure-sensitive electroconductive resin is also essentially definite value, signal will not be caused to become
Change；When there is external touch action to occur, due to subjected to compressive forces, resistance value reduces pressure-sensitive electroconductive resin, and electric current increases
Greatly, the signal of curent change is conducted to signal detection port by the touch control detection line SL being attached thereto, and recognizes row coordinate, together
When, it is different by the sweep time of drives line, can be with lock line coordinate, so as to position the position of touch-control generation.By pressure-sensitive touch-control
The drives line of structure further reduces array base with being multiplexed for the common electrode signal line shown while cost is reduced
The thickness of plate.
Fig. 7 be yet another embodiment of the invention provide array base palte overlooking the structure diagram, the battle array that the present embodiment is provided
The difference for the array base palte that row substrate is provided with Fig. 5,6 is, is not in every drives line and touch control detection line
Pressure-sensitive electroconductive resin is both provided with crossover location.In the present embodiment, such as could be arranged to：Array base palte includes a plurality of the
One sub- drives line CL1 and a plurality of second sub- drives line CL2, pressure-sensitive electroconductive resin 14 are only arranged at the first sub- drives line CL1 with touching
Between control detection line SL.The face being related to when drives line is multiplexed with gate line, during relative to extraneous touch-control on array base palte
Product size, the density of drives line is very big in fact, without all being set in the crossover location of every drives line and touch control detection line
Pressure-sensitive electroconductive resin is equipped with, the density that pressure-sensitive electroconductive resin is set meets touch-control needs, and it is sensitive so neither to influence touch-control
Degree can reduce manufacturing cost again.Wherein first sub- drives line CL1 can be for example arranged at intervals with the second sub- drives line CL2, or
Person is evenly distributed on the viewing area of array base palte, to improve the degree of accuracy of touch control detection.
Further, may be arranged as：Array base palte includes the multiple second sub- drives line groups, each second sub- drives line
Group includes at least a plurality of second sub- drives line CL2, and the second sub- drives line group arranges with the first sub- drives line CL1 alternate intervals.
In the present embodiment, array base palte can also include multiple touch control detection line groups, and each touch control detection line group includes
A plurality of touch control detection line SL, all touch control detection line SL in touch control detection line group are connected to the second lead of same 17, and lead to
Cross second lead 17 to be connected to positioned at the signal detection port of rim area, the signal that the signal detection port is located at rim area drives
In dynamic circuit 18.The size being related to during relative to extraneous touch-control on array base palte, the distribution density of touch control detection line
It is very big in fact, a plurality of touch control detection line may be included in the region that each touch-control is related to, therefore, can be according to above-mentioned
Mode carries out packet setting to touch control detection line, for example, could be arranged to, each touch control detection line group includes N bar touch control detections
Line, the touch control detection line of opening use V1 voltages, and remaining touch control detection line being also not switched on uses V2 voltages, is moved when without touch-control
When work occurs, the N bar touch control detection lines in each touch control detection line group are always an opening, and (N-1) root is not opened, so always
Voltage is V1+ (N-1) V2, flow through all pressure-sensitive electroconductive resins in each touch control detection line group and by the second lead transmit to
The current signal of signal detection port is also essentially definite value, will not cause signal intensity；But when there is touch generation, can
So that all pressure sensitivity electric currents in a touch control detection line group to be gathered together, signal amplification, signal detection port pair is more convenient
The identification of touching signals, increase the touch control detection sensitivity of the pressure-sensitive touch-control structure.
In addition, the present invention also provides a kind of display panel, including any array base palte described in above-described embodiment.Fig. 8
It is a kind of display panel schematic diagram provided in an embodiment of the present invention, the display panel is electrophoretic display panel, the electrophoresis showed face
Plate also includes array base palte 10, electrophoresis film layer 20, common electrode layer 31 and protective layer 30, common electrode layer 31 and is located at protective layer 30
The side towards array base palte 10, electrophoresis film layer 20 is between common electrode layer 31 and array base palte 10.Electrophoresis film layer 20
Including multiple electrophoresis particles, when electrophoretic display panel shows black and white screen, electrophoresis particle can include black electrophoretic particles with
And white electrophoretic particles；When electrophoretic display panel shows colour picture, electrophoresis particle can include the electrophoresis grain of multiple color
Son, such as red electrophoresis particle, blue electrophoresis particle, green electrophoretic particle etc..
The movement of electrophoresis particle can be realized by electric field, that is to say, that electrophoresis particle can be according to public electrode and pixel electricity
Electric field level and direction between pole are correspondingly moved, for example, apply ground voltage to public electrode, and to pixel electrode
Apply data voltage, then the white electrophoretic particles of positively charged can move to public electrode, and electronegative black electrophoretic particles can be to
Pixel electrode moves, and so, when exterior light is from the incidence of pixel electrode side, incident light is anti-by electronegative black electrophoretic particles
Penetrate, black is presented so as to which the pixel can be observed.
When there is extraneous touch to be applied on protective layer, the protective layer at this is caused to be deformed upon with electrophoresis film layer,
Give pressure transmission to pressure-sensitive electroconductive resin, the resistance value of corresponding pressure-sensitive electroconductive resin is according to being applied in the pressure-sensitive electroconductive resin
Compression stress changes, and based on the change for the current value for flowing through the pressure-sensitive electroconductive resin, can detect that the display panel is applied in
The position of touch-control.
Certainly, the display panel is not limited to electrophoretic display panel, can also be applied to the liquid crystal of total-reflection type
Display panel.Because the liquid crystal display panel of electrophoretic display panel and total-reflection type is to aperture opening ratio no requirement (NR), touch control detection line
Cabling mode, position selection and width set it is all relatively free.
Certainly, the display panel can also be transmissive liquid crystal display panel, at this point it is possible to by touch control detection line and number
Set parallel according to line, positioned at shading region, such as touch control detection line can be arranged on to the surface of data wire, can reduced as far as possible
Even eliminate influence of the introducing of touch control detection line to aperture opening ratio.
