Specific embodiment
To the present invention, the array base palte providing and touch-control display panel elaborate below in conjunction with the accompanying drawings.
With reference to Fig. 3, the schematic diagram shown in array base palte first embodiment of the present invention.Include on described array base palte
A plurality of gate line g1 and a plurality of data lines d1, the multiple pixel cell p1 being surrounded by gate line g1 data line d1, array base palte
On also include common electrode layer and drive circuit (not shown).
Common electrode layer is provided with zigzag and slots 39 (in figure dashed box illustrates its position) with will be described public
Electrode layer is divided into multiple sensing pads (in figure illustrates two sensing pads 311,312), the longitudinal grooved of described zigzag fluting 39
391 2 pixel cells of leap, the transversal slotting 392 of described zigzag fluting 39 crosses over 3 pixel cells.Each sensing pad leads to
Cross a touch-control lead (not shown) to electrically connect with described drive circuit, the region of zigzag fluting is not provided with common electrode layer
Described touch-control lead is connected with the sensing pad that it is controlled by via 33.
Common electrode layer has been divided into multiple jagged sensing pads by zigzag fluting 39, between all sensing pads mutually
Insulate, and, sensing pad is electrically connected with the drive circuit of array base palte by touch-control lead.In the touch-control stage, drive circuit is used
In providing touching signals for sensing pad, so that sensing pad is as touch control electrode；In the display stage, drive circuit is additionally operable to as sensing
Pad provides common electric voltage, so that sensing pad is as public electrode.Touch-control lead is used for transmitting public affairs in the display stage to public electrode
Common electrode signal, transmits touch scanning signals in the touch-control stage to touch control electrode, and the touch-control electricity of touch position will occur
The touching signals that pole produces are transferred to drive circuit.Additionally, drive circuit is also electrically connected with gate line g1 data line d1, it is used for
There is provided scanning signal for gate line g1, provide data signal for data wire d1.
Wherein, the extension of longitudinal grooved 391 bearing of trend of zigzag fluting 39 in common electrode layer and data wire d1

The rgbw embedded touch control panel becoming.Rgbw technology is exactly to increased w white sub-pixels on original rgb three primary colories, becomes
Four colour pattern pixel designs.In the present embodiment, still through control transversal slotting 392 length it is ensured that zigzag fluting 39 longitudinal direction
Fluting 391 is between r, b color blocking；In the present embodiment, longitudinal grooved 1 pixel cell of 391 longitudinal crossing of zigzag fluting 39
P1, the transversal slotting 392 of described zigzag fluting 39 crosses over 2 pixel cells.In rgbw embedded touch control panel, by saw
Profile of tooth mode of grooving, longitudinal grooved is placed between color blocking r and b, reduces the shadow slotted in common electrode layer to g color blocking penetrance
Ring.This pixel cell illustrated in the letter (r, g, b, w) that in diagram, each pixel cell indicates is corresponding sub-pixel.
In other embodiments, the longitudinal grooved 391 of zigzag fluting 39 can be with longitudinal crossing 4 and above pixel cell
p1.
Present invention also offers a kind of touch-control display panel, described touch-control display panel is provided with array of the present invention
Substrate.Using the touch-control display panel of array base palte of the present invention, by sensing pad demarcation line is changed to saw by linear
Profile of tooth, can make the touch-control lead on demarcation line across on two adjacent sensing pads, touch-control lead can run through it and be controlled
Sensing pad or run through whole panel.This zigzag mode of grooving can by touch-control lead in common electrode layer unslotted area
Domain is connected with the sensing pad that it is controlled by il hole, so, there is not floating metal in one side panel, reduces and electrostatic occurs
Residual or the risk of damage by static electricity, on the other hand, without bridge, increase the panel homogeneity of In-cell touch display panel.?
