Optionally, Fig. 7 is the structural schematic diagram of another display panel provided in an embodiment of the present invention.Referring to Fig. 7, single The both ends of second conducting wire 2021 extend respectively in two adjacent touch control electrodes 20, wherein two touch-controls adjacent positioned at this Second conducting wire 2021 in electrode 20 is referred to as the first conductive part 20211 and the second conductive part 20212, adjacent positioned at this Second conducting wire 2021 in interval between two touch control electrodes 20 is known as third conductive part 20213；Along first direction X, One conductive part 20211 and two conductive parts 20212 are located at the both ends of third conductive part 20213；Wherein, the first conductive part 20211 are located between two first conducting wires 201 in a touch control electrode 20 on second direction Y；Second conductive part 20212 exists It is located between two first conducting wires 201 in another touch control electrode 20 on second direction Y；Third conductive part 20213 is second On the Y of direction not between the first conducting wire 201.The length C2 of the length C1 of first conductive part 20211, the second conductive part 20212 Meet with the length C3 of third conductive part 20213: C1≤C3 < C2.
Wherein, the second conducting wire 2021 is electrically insulated with each sub-conductor 2011 in the first conducting wire, i.e. the second conducting wire 2021 with Touch control electrode 20 is electrically insulated.When touch action occurs, coupled capacitor can be still generated on the second conducting wire 2021, which can Influence the touch sense signals on the first conducting wire 201 adjacent thereto.
Wherein, when touch action (or referred to as touch action) occurs at the corresponding position of the second conducting wire 2021, the Coupled capacitor can be generated on two conducting wires 2021, if in the range of the profile that the second conducting wire 2021 extends to touch control electrode 20 surrounds, The coupled capacitor generated on second conducting wire 2021 will affect touch control capacitance, and here, touch control capacitance is touch control electrode in response to touching The capacitor of control movement and generation.
Based on this, the second conducting wire 2021 can be set in the interval between adjacent touch control electrode 20.But only at this The structure that the second conducting wire 2021 is arranged in interval is easier to make the display panel 10 that there are the dummy electrodes that the second conducting wire 2021 is constituted The visible risk of 202 profile.Therefore, the second conducting wire 2021 can be extended in the range of the profile encirclement of touch control electrode 20.
Comprehensively consider the coupled capacitor problem generated on the second conducting wire 2021 problem visible with the profile of dummy electrode 202, Second conducting wire 2021 can be extended only in the touch control electrode 20 of 202 side of dummy electrode, and be not extend to positioned at the void If specifically can refer to Fig. 5 in the touch control electrode 20 of the other side of electrode 202.
The set-up mode of second conducting wire 2021 of the dummy electrode 202 in the display panel referring to shown in Fig. 5.In Fig. 5 For the orientation shown, touch control electrode 20 can be described as left side touch control electrode and right side touch control electrode, touch control electrode and the right side in left side Dummy electrode 202 is set between the touch control electrode of side, and dummy electrode 202 is made of a plurality of second conducting wire 2021.A plurality of in figure Two conducting wires 2021 can be divided into two classes: in the range of the profile that the second conducting wire of one type extends only to right side touch control electrode surrounds, Two i.e. between such second conducting wire and the first conducting wire are interrupted in a little, and one is beaten breakpoint setup in the profile of left side touch control electrode On, another dozen of breakpoint setups are in the inside of right side touch control electrode；Wherein another kind of second conducting wire extends only to left side touch-control electricity In the range of the profile of pole surrounds, i.e., two between such second conducting wire and the first conducting wire are interrupted in a little, and one is interrupted and a little sets It sets on the profile of right side touch control electrode, another dozen of breakpoint setups are in the range of the profile of left side touch control electrode surrounds.It is right The two further analyses of the second conducting wire of class 2021 in the dummy electrode 202, it is known that: extend only to the profile packet of right side touch control electrode The coupled capacitor generated on the second conducting wire 2021 in the range of enclosing only has an impact to the touch control capacitance of right side touch control electrode, without It will affect the touch control capacitance of left side touch control electrode；Extend only to the second conducting wire in the range of the profile encirclement of left side touch control electrode Coupled capacitor on 2021 only has an impact to the touch control capacitance of left side touch control electrode, the touch-control without will affect right side touch control electrode Capacitor.Therefore, influence of the coupled capacitor generated on the second conducting wire 2021 to touch control capacitance, can be mended using driving circuit It repays, simplified control algorithm, thus it is advantageously ensured that the touch-control accuracy of display panel.
In display panel shown in Fig. 5, it would still be possible to which there are more interrupting a little to be set on the profile of touch control electrode 20, is Be further reduced interrupting a little on the profile of touch control electrode 20, the second conducting wire 2021 in dummy electrode 202 can be extended to In adjacent two (i.e. adjacent with dummy electrode 202 along the first direction X) touch control electrodes 20 of dummy electrode 202 or so, specifically may be used Referring to Fig. 7.
In display panel shown in Fig. 7, led by above-mentioned first conductive part 20211, the second conductive part 20212 and third The setting of the length relation in electric portion 20213 can make the coupled capacitor generated on the second conducting wire 2021 equivalent can regard third conduction as The touch sense signals that the touch control electrode 20 that portion 20213 extends to senses, and the coupled capacitor prolongs the first conductive part 20211 The influence that the touch control electrode 20 reached senses side touch sense signals is negligible, is avoiding figure visible to be promoted and be shown as a result, Under the premise of the picture display effect for showing panel, it can be ensured that the touch function of display panel is good.
It makes a concrete analysis of as follows: using orientation shown in Fig. 7 as example, when the both ends of the second conducting wire 2021 extend respectively to phase In the range of the profile of two adjacent touch control electrodes 20 surrounds, i.e. the both ends of the second conducting wire 2021 extend respectively to left side touch-control electricity When in the range of the profile of pole surrounding and in the range of the encirclement of the profile of right side touch control electrode, second conducting wire 2021 is to touch-control electricity The influence of appearance can understand in terms of following two: in a first aspect, since the second conducting wire of this bar 2021 does not extend only to left side touch-control electricity In the range of the profile of pole surrounds, also extend in the range of the profile encirclement of right side touch control electrode, therefore, the second conducting wire of this bar The coupled capacitor generated on 2021 can not only have an impact to the touch control capacitance of left side touch control electrode, also can be to right side touch control electrode Touch control capacitance has an impact；Second aspect, also due to the second conducting wire of this bar 2021 does not extend only to the profile of left side touch control electrode It in the range of encirclement, also extends in the range of the profile encirclement of right side touch control electrode, therefore, the second conducting wire of this bar 2021 can incite somebody to action The touching signals of left side touch control electrode are conducted to right side touch control electrode, or the touching signals of right side touch control electrode are conducted to left side Touch control electrode, thus, interference is generated between left side touch control electrode and the touching signals of right side touch control electrode.
