To extension；Second touch control electrode item 120 is along the second direction setting intersected with first direction, specifically second touch control electrode item
120 length extends in a second direction.Specifically, first direction and second direction are mutually perpendicular to.For example, as shown in Figure 1, with water
Square to being second direction for first direction, vertical direction, then one the first touch control electrode item of the behavior in horizontal direction
110, one on vertical direction is classified as second touch control electrode item 120.It is appreciated that in other embodiments, first direction and the
It two directions can not also be vertical.
Fluting or chamfering are carried out to capacitance type touch-control panel, can the touch drive electrode item that is slotted or is chamfered and/

The corresponding resnstance transformer unit of electrode is in parallel, and specifically one special-shaped crossed electrode 11 and a resnstance transformer unit are simultaneously
Connection, different abnormity crossed electrodes 11 resnstance transformer unit in parallel are different.
Since fluting or chamfering cause that the electrode of special-shaped crossed electrode 11 lacks, area lacks, in special-shaped crossed electrode 11
The area lacked corresponds to resistance value, and resistance value corresponding with real area is the relationship of parallel connection, that is, meets relationship：
Wherein, RsIndicate the corresponding resistance value of real area of special-shaped crossed electrode 11, RqIt indicates to lack in special-shaped crossed electrode 11
The corresponding resistance value of few area, RzIndicate the corresponding resistance value of the gross area of regular crossed electrode 12.As it can be seen that special-shaped crossed electrode 11
Electrode missing the resistance value of special-shaped crossed electrode 11 can be caused to increase, 11 corresponding touching signals of special-shaped crossed electrode are relative to rule
