S30 step particularly as follows: phase III P3, an IC by with the first sub-common electrical
First cabling 102 input pressure detection signal of pole 1011 electrical connection；2nd IC is by with
Second cabling 202 of one sub-opposite electrode 2011 electrical connection inputs the second fixed voltage signal,
Or control opposite electrode 201 ground connection.
Wherein, second stage P2 and phase III P3 are same stage.
It should be noted that the concrete table that second stage P2 and phase III P3 are same stage
Existing form is: liquid crystal display, while carrying out touch control detection, can carry out pressure detecting,
Both there is no dividing of sequencing.
This utility model embodiment is by by one of them sub-public electrode in public electrode 101
Such as second sub-public electrode 1012 as touch control electrode, another sub-public electrode such as
One sub-public electrode 1011 is as pressure detecting electrode, on this basis, by controlling to the
One sub-opposite electrode 2011 and the signal of the second sub-opposite electrode 2012 input, just can be the most real
Existing touch-control and pressure detecting function.Wherein, when realizing pressure detecting function, owing to needs are controlled
Make first sub-opposite electrode 2011 ground connection corresponding with the first sub-public electrode 1011 or to first
Sub-opposite electrode 2011 inputs fixed voltage signal, is equivalent to be formed screen between touch control electrode
Cover layer, thus the mutual crosstalk between touch control electrode can be avoided.
Preferably, between arbitrary neighborhood opposite electrode 201, also stacking is provided with metal electrode
40 and semiconductor layer 50 in the case of, said method also includes:
As shown in figure 18, in second stage P2, the 3rd IC control metal electrode 40 unsettled or
Ground connection；Signal is opened to metal electrode 40 input at phase III P3, the 3rd IC, so that
Adjacent opposite electrode 201 turns on.Wherein, metal electricity is controlled at first stage P1, the 3rd IC
Pole 40 is unsettled, ground connection, input open signal.
Concrete, at first stage P1, an IC by the first cabling 102 to public electrode
101 input common electric voltage Vcom signals；3rd IC controls that metal electrode 40 is unsettled or ground connection；
2nd IC inputs the first fixed voltage signal by the second cabling 202 to opposite electrode 201,
Or control opposite electrode 201 is unsettled or ground connection.
In second stage P2, in second stage P2, an IC passes through the first cabling 102 to public affairs
Common electrode 101 inputs touching signals；3rd IC controls that metal electrode 40 is unsettled or ground connection；The
Two IC synchronize input touching signals by the second cabling 202 to opposite electrode 201, or control
Opposite electrode 201 is unsettled.
Inputted to public electrode 101 by the first cabling 102 at phase III P3, an IC
Pressure detecting signal；3rd IC opens signal to metal electrode 40 input；2nd IC passes through
Second cabling 202 inputs the second fixed voltage such as common electric voltage Vcom to opposite electrode 201
Signal, or control opposite electrode 201 ground connection.
It should be noted that the 3rd IC can be same IC with an IC or the 2nd IC,
Or an IC, the 2nd IC and the 3rd IC are same IC.
This utility model embodiment passes through the 3rd IC control to metal electrode 40, can be at liquid crystal
Display floater 01 realizes making opposite electrode 201 disconnect during touch controllable function, to avoid touch control electrode
Between crosstalk；All opposed electricity are made when display panels 01 realizes pressure functional detection
Pole 201 electrically connects, and finger can be avoided at an arbitrary position to pressure detecting electrode and opposed electricity
The impact of electric capacity is produced between pole 201.
The above, detailed description of the invention the most of the present utility model, but guarantor of the present utility model
The scope of protecting is not limited thereto, and any those familiar with the art is at this utility model
In the technical scope disclosed, change can be readily occurred in or replace, all should contain at this utility model
Protection domain within.Therefore, protection domain of the present utility model should be with described claim
Protection domain is as the criterion.
