Currently, the display screen of mainstream mostly uses LCD technology.On the other hand, with information technology, radio mobile communication and
The fast development of information household appliances and application, many information products more convenient, lighter and handier and more humane in order to achieve the purpose that
It is inputted by devices such as traditional keyboards or mouse, switchs to use touch panel (Touch Panel) as input unit,
In, touch control liquid crystal display device has become main product.
Touch control display apparatus can be generally divided into four seed types, respectively according to the difference of its working principle and transmission medium
Resistance-type, capacitor induction type, infrared-type and surface acoustic wave type.Wherein capacitive touch control display device is since it is with high score
Resolution, high sensitivity and it is durable the advantages that be widely used.The principle of capacitive touch control display device be by measurement finger or
Influence of other touch control objects between coupled capacitor touch screen electrode, to detect the position of finger or other touch control objects on the touchscreen
It sets.
Fig. 1 is the structural schematic diagram of existing touch control liquid crystal display device.As shown in Figure 1, the touch control display apparatus includes

The conducting wire 7 and 2 quantity of periphery cabling that driving electrodes 4 connect also can be very more, to will cause routing region (i.e. touch-control blind area)
Area it is bigger.The presence of larger area routing region on the one hand can to occur in the location Calculation for touching object compared with
Big deviation, the reason is that when touching object is moved in another touch-control sensing unit from a touch-control sensing unit, it is wider
Touch-control blind area can make touching object that can not cover another touch-control sensing unit immediately, therefore, carry out location Calculation
When cannot achieve stable transition, previous touch-control sensing unit can be biased to when carrying out location Calculation, thus influence display dress
Set touch-control precision.On the other hand, because there are the routing regions of larger area, so to make the display device that there is same size
Touch area, the size of display device touch screen is bigger, be unfavorable for using the touch screen display device miniaturization hair
Exhibition, is unfavorable for narrow frame design.
