Moving electrode.The most as shown in figure 11, in position of touch detection time period T2, send out to touch-control drive electrode TX and pressure detecting electrode
Touch-control is sent to drive signal.In addition to this it is possible to send display drive signals to pressure detecting electrode.
It addition, in the pressure detecting time period, send pressure detecting to pressure detecting electrode and drive signal to include:
The pressure detecting time period, send display drive signals to touch-control drive electrode, send first to touch-control sensing electrode constant simultaneously
Voltage signal, the first constant voltage signal includes ground signalling GND.
Here display drive signals is different according to the concrete structure of display floater, refers specifically to for the different signals of telecommunication.Tool
Body ground, if display floater is display panels, display drive signals here is public voltage signal.If display floater is for having
Machine LED display panel, and pressure detecting electrode and anode layer be positioned in same film layer, display drive signals here
For anode voltage signal.If display floater is organic LED display panel, and pressure detecting electrode is positioned at cathode layer
In same film layer, display drive signals here is cathode voltage signal.
In order to prevent from being formed between touch-control drive electrode and conductive film layer parasitic capacitance, affect touch-control on touch-control drive electrode
Drive the input of signal, and then affect the sensitivity that position of touch detects, alternatively, such as Figure 10 and Figure 11, examine at position of touch
Surveying the time period, conductive film layer sends touch-control and drives signal；Meanwhile, the time period is detected at position of touch, to pressure detecting electrode
Sending touch-control and drive signal, can prevent from being formed between pressure detecting electrode and conductive film layer parasitic capacitance further, impact is touched
Capacitance variations between control drive electrode and touch-control sensing electrode, causes the sensitivity decrease that position of touch detects.Additionally, it is optional
Ground, in the pressure detecting time period, conductive film layer sends the second constant voltage signal, and the second constant voltage signal equally can also
Including ground signalling.
It should be noted that in the above-described embodiments, although with low level signal, Figure 10 and Figure 11 represents that display drives letter
Number, but be not the restriction of the voltage magnitude to display drive signals, during specific works, the voltage magnitude of this display drive signals
Can be zero, it is also possible to be a lower voltage value or a higher voltage value, specifically depend on the circumstances.
The embodiment of the present invention is by being arranged at touch control electrode and pressure detecting electrode in same film layer, and shows at touch-control
Device is set up conductive film layer, when utilization acts on when pressing touch control display apparatus, between conductive film layer and display floater
Pressure deformation gap deform upon so that the electric capacity between pressure detecting electrode and conductive film layer changes, and then makes
The signal of telecommunication of pressure detecting electrode output changes this characteristic, reaches the mesh detecting the force value of user's input
, solving touch control display apparatus and pressure transducer in prior art needs to make respectively, is shown by touch-control after making again
Showing device and pressure transducer are assembled together, the problem that processing technology is numerous and diverse, it is achieved simplify touching with pressure detecting function
The effect of the processing technology of control display device.
