In order to make it easy to understand, first structure and scan mode to In-cell touch panel are introduced.Refering to figure
2, Fig. 2 is the structural representation of the touch-control display panel of a kind of In-cell touch panel disclosed in prior art.Touch-control shown in Fig. 2
Display floater includes driving IC, a plurality of gate line 1, a plurality of public electrode 2, a plurality of touch-control sensing electrode (RX) 3, multiplexing common electrical
Pole 2 is touch-control drive electrode (TX).Wherein, a plurality of gate line 1 and a plurality of public electrode 2 are used for coordinating realization display scanning, many
Bar touch-control sensing electrode 3 and a plurality of public electrode 2 realize touch-control scanning for cooperation.Drive owing to public electrode 2 is multiplexed with touch-control
Moving electrode, so, display scanning and touch-control scanning can only be carried out in timesharing, i.e. carry out display scanning in the display scan period, touching
The control scan period carries out touch-control scanning.In the display scan period, IC is driven to scan signal to the input display of a plurality of gate line 1, to
A plurality of public electrode input VCOM voltage, under the cooperation of display scanning signal and VCOM voltage, performs display scanning.At touch-control
Scan period, IC is driven to input touch scanning signals to a plurality of touch-control sensing electrode 3, to a plurality of public electrode 2 input pulse electricity
Pressure, under the cooperation of touch scanning signals and pulse voltage, performs touch-control scanning.
But, in this manner, when the voltage of public electrode 2 input is pulse voltage from the VCOM voltage jump of direct current
Moment, there is Line defect phenomenon, greatly have impact on the quality of touch-control display panel in touch-control display panel.
It is a kind of touch-control scan method disclosed in the embodiment of the present invention refering to Fig. 3, Fig. 3.Described touch-control scan method includes
Following steps:
310: in the display scan period, input VCOM voltage to public electrode, to sweep with the display inputted to gate line
Retouch under the cooperation of signal, perform display scanning.
320: the first time period in the touch-control scan period, input First Transition voltage to public electrode.
330: the second time period in the touch-control scan period, to public electrode input pulse voltage, with to touch-control
Under the cooperation of the touch scanning signals of induction electrode input, perform touch-control scanning.
In order to prevent the voltage of public electrode from VCOM voltage jump to pulse voltage, can set in the touch-control scan period
Put first time period, first time period inputs First Transition voltage to be gradually transitions pulse voltage from VCOM voltage.Its
In, the First Transition voltage value in the start time of first time period is equal to VCOM voltage, in the finish time of first time period
Value equal to the amplitude of pulse voltage, the value of the start time of first time period to finish time is positioned at VCOM voltage and pulse electricity
Between the amplitude of pressure.Such as, First Transition voltage be initial voltage be VCOM voltage, end voltage is pulse voltage amplitude, in
Voltage that oblique line rises etc..
Here, first time period t1 is that the touch-control scan period is after the display scan period terminates as shown in Figure 4
Starting, but drive IC not yet to a period of time of public electrode input pulse voltage, in other words, first time period t1 is also
Be exactly start the touch-control scan period after, touch-control t2 sweep time start before time.In order to can be steadily from VCOM voltage
Being transitioned into pulse voltage, in the case of allowing, the time of first time period, the longer the better.And, by contrasting with Fig. 1
It is found that the time that time of starting sweep time of the touch-control shown in Fig. 4 starts than the touch-control of prior art sweep time
Want evening, to provide time enough to input First Transition voltage.
In a specific embodiment, First Transition voltage except on magnitude of voltage gradually from VCOM voltage-transition to pulse
Outside voltage, in addition it is also necessary to be gradually transitions the waveform of pulse voltage from the waveform of direct current.Thus it is possible to first time period t1 is divided into
First timesharing, the second timesharing and the 3rd timesharing.In the first timesharing, First Transition voltage is the pulse that magnitude of voltage is equal to ground voltage
Voltage, wherein, ground voltage approximates VCOM voltage；In the second timesharing, First Transition voltage is the arteries and veins that magnitude of voltage is equal to half voltage
Rushing voltage, wherein, half voltage is equal to the half of the amplitude of pulse voltage；In the 3rd timesharing, First Transition voltage is magnitude of voltage etc.
In the pulse voltage of quasi-voltage, wherein, quasi-voltage is equal to the amplitude of pulse voltage.
Further, owing to the scan period is periodically variable, after VCOM voltage becomes pulse voltage, again can be from arteries and veins
Rush voltage and again become VCOM voltage, so, in order to prevent the voltage of public electrode from jumping to VCOM voltage from pulse voltage, also
3rd time period t 3 can be set in the touch-control scan period, in the 3rd time period t 3, input the second transition electricity to public electrode
Pressure is to be transitioned into VCOM voltage from pulse voltage.Wherein, second transient voltage value in the start time of the 3rd time period is equal to
The amplitude of pulse voltage, in the value of finish time of the 3rd time period t 3 equal to VCOM voltage, during the beginning of the 3rd time period t 3
The value of quarter to finish time is between the amplitude of pulse voltage and VCOM voltage.Such as, the second transient voltage is initial voltage
For pulse voltage amplitude, end voltage is VCOM voltage, voltage declined in oblique line etc..
Here, the 3rd time period t 3 is to finish the second time period, but, a period of time that display scanning does not starts.
In order to steadily VCOM voltage can be transitioned into from pulse voltage, allow in the case of, the time of the 3rd time period t 3 the longest more
Good.
In a specific embodiment, in order to reduce the time of transition, make the second transient voltage in the 3rd time period t 3
Value is equal to ground voltage, and wherein, ground voltage is equal to VCOM voltage.
In a specific embodiment, the second transient voltage is except being gradually transitioned into VCOM from pulse voltage on magnitude of voltage
Outside voltage, in addition it is also necessary to be gradually transitions the waveform of direct current from the waveform of pulse voltage.Thus it is possible to the 3rd time period t 3 is divided into
4th timesharing, the 5th timesharing and the 6th timesharing.In the 4th timesharing, the value of the second transient voltage is equal to quasi-voltage；At the 5th point
Time, the value of the second transient voltage is equal to half voltage；In the 6th timesharing, the value of the second transient voltage is equal to ground voltage.
The embodiment of the invention also discloses a kind of touch-control display panel, described touch-control display panel includes a plurality of gate line,
A plurality of public electrode, a plurality of touch-control sensing electrode, the bearing of trend of described a plurality of public electrode and described gate line bearing of trend
Parallel, described a plurality of public electrode is multiplexed with touch-control drive electrode, described touch-control display panel for realize as shown in Figure 3 touch
Control display packing, the most no longer specifically describes.
The present invention inputs First Transition voltage by the first time period in the touch-control scan period so that the electricity of public electrode
Pressure is pulse voltage from DC voltage slowly transition, prevents touch screen from Line defect phenomenon occur, it is provided that the display of touch screen
