Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried outDescribe clearly and completely, obviously, described embodiment is only the present invention's part embodiment, andNot whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not doingGo out the every other embodiment obtaining under creative work prerequisite, all belong to the scope of protection of the invention.
One embodiment of the present of invention provide a kind of array base palte, and this array base palte comprises substrate and establishesPut the many strip electrodes cabling on this substrate, as shown in Figure 1, this electrode cabling comprise functional pin A1,With the lead-out wire A2 of the driving element IC electrical connection of array base palte and be communicated with this functional pin A1 and drawThe auxiliary electrode B1 of outlet A2, wherein, the sheet resistance of auxiliary electrode B1 is greater than the sheet resistance of functional pin A1Or the sheet resistance of lead-out wire A2.
In the present embodiment, array base palte comprises many gate lines, many data wires and by gate line and numberThe pixel cell surrounding according to line, wherein, driving element IC is by providing driving letter to gate line and data wireNumber drive pixel cell to carry out the demonstration of picture. In another embodiment of the present invention, array base palte alsoCan be touch display substrate, this touch display substrate comprises the touch-control electrode of multiple array arrangements, eachTouch-control electrode is connected with driving element IC by a touch-control cabling, for touching signals is transferred to driverPart IC, realizes the detection of position of touch etc.
Based on this, the functional pin A1 in the present embodiment can be gate line, data wire or touch-control lead-in wire,But the present invention is not limited to this, this functional pin A1 can also be other functions on array base palteLead-in wire, as long as it need to be connected with driving element IC with lead-out wire A2 by auxiliary electrode B1.
Wherein, the many strip electrodes cabling in the present embodiment can be for transmission same type signal, for example,Functional pin A1 in the present embodiment is gate line, data wire or touch-control lead-in wire, or functional pinA1 is the part cabling in gate line, data wire and touch-control lead-in wire.
In the present embodiment, auxiliary electrode B1 is transparent conductive material, and optional, auxiliary electrode B1 canFor tin indium oxide (ITO) material.
