Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are please referred to, below to introduce the first of the touching control device 26 of the present invention
Embodiment is comprising an integrator 28 and a touching controller 32.Integrator 28 is electrically connected a touch-control display panel 36, touching
Controlling display panel 36 has an electrod-array, as shown in Figure 1.Electrod-array includes a sensing substrate 38 and plurality of electrodes group
40, each electrode group 40 includes one of to be separated by the first touch control electrode 42, at least a second touch control electrode 44 and a third
Touch control electrode 46, in this electrod-array, the quantity of second touch control electrode 44 is two, one of second touch control electrode 44
Between the first touch control electrode 42 and third touch control electrode 46, third touch control electrode 46 be located at two second touch control electrodes 44 it
Between.Two second touch control electrodes 44 and the first touch control electrode 42 form a touching mutual capacitance 47, third touch control electrode 46 and first
Touch control electrode 42 forms an induction mutual capacitance 48, and each electrode group 40 has a baseline (baseline) capacitance C0, baseline
When capacitance C0 is that electrode group 40 is not touched, the summation capacitance of all self-capacitances and mutual capacitance.In the first touch-control electricity
The confluce and the first touch control electrode 42 of pole 42 and second touch control electrode 44 and the confluce of third touch control electrode 46 have one absolutely
Edge layer, this insulating layer is between the first touch control electrode 42 and second touch control electrode 44 and the first touch control electrode 42 and third touch-control
It is in electrical contact to avoid the first touch control electrode 42 and second touch control electrode 44 between electrode 46, while avoiding the first touch control electrode
42 is in electrical contact with third touch control electrode 46.
When object 50 is non-conductor and touching electrode group 40, object 50 will not take away electric field, and only will affect electric field

It is distributed in non-conductor more, the capacitance CM for incuding mutual capacitance 48 is made to be greater than base line capacitance value C0.In Fig. 4, object is worked as in L1 representative
When body 50 is non-conductor, capacitance CA and CM start the object 50 changed at a distance of the shortest distance of electrod-array, and object is worked as in L2 representative
When body 50 is conductor, capacitance CA and CM start the object 50 changed at a distance of the shortest distance of electrod-array.When object 50 is non-
Conductor, and object 50 at a distance of the shortest distance of electrod-array be L2 when, capacitance CA and CM are all equal to base line capacitance value C0.Work as object
Body 50 be non-conductor, and object 50 at a distance of electrod-array the shortest distance be less than or equal to L1 when, capacitance CA be less than baseline electricity
Capacitance C0, capacitance CM are greater than base line capacitance value C0.When object 50 be conductor, and object 50 at a distance of electrod-array the shortest distance

Press VM.It touches controller 32 and is electrically connected integrator 28, touching controller 32 has one of corresponding base line capacitance value C0 baseline
(baseline) voltage, one first threshold value and it is greater than the second threshold value of one of the first threshold value.It touches controller 32 and receives sense
Voltage VM is answered, and obtains the absolute value of the difference of induced voltage VM and baseline voltage.Induced voltage is judged in touching controller 32
VM be less than baseline voltage, and absolute value be greater than the first threshold value when, touching 32 judgment object 50 of controller be non-conductor, and according to
The position of induced voltage VM record non-conductor counter electrode array.Judge that induced voltage VM is greater than or equal in touching controller 32
Baseline voltage, and when absolute value is greater than the second threshold value, touching 32 judgment object 50 of controller is conductor, and according to induced voltage
The position of VM record conductor counter electrode array.In some embodiments of the present invention, when touching controller 32 judges absolute value
When continuing one first preset period of time greater than the first threshold value, touching controller 32 records the corresponding electricity of non-conductor according to induced voltage VM
The position of pole array.In some embodiments of the present invention, when touch controller 32 judge absolute value continue one second it is default when

Preset period of time can be adjusted according to demand with the second preset period of time, set the use of the first preset period of time and the second preset period of time
Meaning is the situation for receiving instantaneous noise in order to avoid touching controller 32 and causing erroneous judgement.
As can be seen from Figure 4, when object 50 is conductor, as the shortest distance between object 50 and electrod-array is shorter, sense
It answers capacitance CM lower, and is far below base line capacitance value C0.When object 50 is non-conductor, with object 50 and electrod-array it
Between the shortest distance it is shorter, induced electricity capacitance CM is higher, and slightly above base line capacitance value C0.In induction, mutual capacitance 48 is corresponding fills
Under the premise of electric current and charging time are all fixed, induced electricity capacitance CM is inversely proportional with induced voltage VM.Therefore, the present invention judges
Induced voltage VM be less than baseline voltage when, object 50 be non-conductor, and judge induced voltage VM be greater than or equal to baseline voltage when,
Object 50 is conductor.In addition, because induced electricity capacitance CM's changes greatly when object 50 is conductor, when object 50 is non-leads
When body, the variation of induced electricity capacitance CM is smaller, so the second threshold value need to be greater than the first threshold value, the present invention utilizes two differences
Threshold value go the touching behavior for judging conductor and non-conductor whether effective, to promote the touch-control sensitivity of non-conductor or conductor,
