The schematic diagram of driving circuit 500.As shown in figure 5, one (n-1)th grade of gate line drive circuit 510 is to generate an output signal
Gn-1.Output signal Gn-1 is not only used to one (n-1)th gate line Gn-1 of driving, is also used to control one n-th grade of gate line and drives
One transistor M1 of dynamic circuit 520.Similarly, an output signal Gn is also for driving a nth gate line Gn and control one n-th
One transistor (not shown) of+1 grade of gate line drive circuit.In the present embodiment, Gn had both represented the nth gate line, also generation
The output signal on table- driven nth gate line Gn.
Fig. 6 is the timing diagram of n-th grade of gate line drive circuit 520 of an embodiment according to the present invention.Wherein, when this is defeated
When signal Gn-1 is a high voltage out, a transistor M1 is for conducting.One VDS signal is a direct current (DC) high voltage signal, institute
One first high voltage VGH1 can be charged to a control node N of n-th grade of gate line drive circuit 520 at this time.When this is defeated
When signal Gn-1 becomes a low-voltage out, a pull-down circuit 521 is closed state, i.e. control node N can be maintained at this
One high voltage VGH1.A transistor M9 is connected at this time.When the signal CK on transistor M9 source electrode switchs to one by a low-voltage
When high voltage, due to there is the relationship of capacitor 3P, the voltage of control node N can be promoted to one second high voltage VGH2.And by
It is connected in transistor M9, therefore signal CK flows through transistor M9, output signal Gn can be drawn as the high voltage, with driving
Nth gate line Gn, and charge simultaneously to the control node N of the gate line drive circuit of a next stage.So this is defeated
The width of signal Gn can be controlled by signal CK out.When by the high voltage to switch to this low by the signal CK on transistor M9 source electrode
When voltage, the voltage of control node N can be pulled low to first high voltage VGH1, and transistor M9 is connected.Although at this time
Transistor M9 conducting, but signal CK switchs to the low-voltage, therefore output signal Gn can become the low-voltage.
According to the timing diagram of Fig. 6, which can be divided into an area I to be scanned, a preliminary filling area II, one open
It opens area III, an area IV to be closed and area V is completed in a scanning.In preliminary filling area II, transistor M1 is by the lock of the previous stage
Polar curve driving circuit 510 is opened, and to be pre-charged to control node N, control node N is in first high voltage
VGH1.In unlatching area III, control node N drives the gate line in second high voltage VGH2, output signal Gn
Gn.In the area IV to be closed, in first high voltage VGH1, but at this time, output signal Gn is the low electricity to control node N
Pressure.It is completed in area V in the scanning, control node N and output signal Gn are the low-voltage.
It will be appreciated from fig. 6 that the gate line drive circuit 520 drives gate line Gn, at this time the number in unlatching area III
It can be written in relevant picture element via the driving component 2115 according to the data on line 2113.Therefore unlatching area III not
It is suitble into hole.
It in the preliminary filling area II and is somebody's turn to do in area IV to be closed, although the gate line drive circuit 520 does not drive the gate line
Gn, but control node N can be opened in first high voltage VGH1, transistor M9 until scanning completion area V is just closed.
The gate line drive circuit 520 will appear two states, and the state of both gate line drive circuits 520 produces two kinds respectively
Different environmental capacitances, wherein a state 1 is the area I to be scanned and area V is completed in the scanning, another state 2 is preliminary filling area II
And it should area IV be closed.
The general gate line drive circuit 520 is using leggy mode to drive the gate line 2111.Fig. 7 is the present invention
Gate line drive circuit 520 using 8 phases (8-phase) driving timing diagram.In Fig. 7, being represented with the signal of N beginning should
Control node N, such as NL3 represent the control of the 210 third left gate line drive circuit 520 of In-cell touch display panel
Node N.Output signal is represented with the signal that G starts, such as GR4 represents 210 fourth right of In-cell touch display panel
The output signal of gate line drive circuit 520.As shown in fig. 7, the expression of block 710 stops cheating position.Enter hole, such as B after GL4
Shown in area.At this time because GR5 is not yet high voltage, so the node voltage of control node NR3 is pulled down to low potential not yet, because
This into hole when have the corresponding gate line drive circuit 520 of 8 gate lines control node N be in high potential state (NR3,
NL3, NR4, NL4, NR5, NL5, NR6, VL6), it is in the M9 transistor of the corresponding gate line drive circuit 520 of 8 gate lines
On state, and then influence the initial data (raw data) when the touching that transparent electrode 400 is read.As shown in Figure 7 may be used
Know, the positions of four gate lines influences whether that transparent electrode 400 is read after entering the position of preceding four gate lines in hole and entering to cheat
Touching when initial data.
Similarly, when the gate line drive circuit 520 is using 6 phase driven, enter to cheat first three gate line position and
Enter the initial data when positions of three gate lines behind hole influences whether the touching that transparent electrode 400 is read.
Fig. 8 is the schematic diagram for entering to cheat position Yu impacted gate line position of the invention.Gate line drive circuit 520 uses
8 phase drivens, corresponding 40 gate lines of every a line touch-control sensing electrode.For simplified form, two row touch-control senses are only drawn in fig. 8
Survey part gate line corresponding to electrode 403 and 404.Causing initial data variation is and the gate line drive circuit 520 when entering to cheat
Control node N voltage it is related.The item number of initial data when gate line influences touching is 8 (after entering to cheat first 4 and going out to cheat
4).When these gate lines are at different picture frames (frame), the item number across touch-control sensing electrode is different, just has original number
According to variation.
In fig. 8, to be with a gate line G112 be into position is cheated, which does not touch
When, the initial data which is obtained is basic data (Base data), to be compared.Meanwhile the touch-control
Controller 230 is also using basic data as whether having the comparison foundation of touching.Being labeled as 810 rectangle frames indicates that gate line G116 is
Enter to cheat position, when which does not touch, the initial data that is obtained.It is labeled as the expression of 820 rectangle frames
Gate line G117 be into cheating position, when which does not touch, the initial data obtained, sequentially class
It pushes away.
When gate line G116 be into cheat initial data that position is obtained with when gate line G112 is is obtained into cheating position
Initial data compare, there is no notable differences.And when a gate line G117 be into cheat initial data that position is obtained with when should
Gate line G112 is to compare into cheating the initial data that position is obtained, then notable difference occurs.Meanwhile as gate line G118 to gate
Line G124 be respectively into cheat initial data that position is obtained with when gate line G112 is into cheating the initial data phase obtained position
Than also having notable difference, and difference is more and more obvious.When a gate line G125 be into cheat initial data that position is obtained with when should
Gate line G124 is to compare into cheating the initial data that position is obtained, without notable difference.That is, when gate line G125 is into hole
The initial data that position is obtained is into the difference for cheating the initial data that position is obtained and when the gate line with gate line G112 is worked as
G124 be into cheat initial data that position is obtained with when gate line G112 be into the difference for cheating the initial data that position is obtained, and
There is no significant change.
From the foregoing it will be appreciated that being depended on entering the gate number of lines at the gate line drive circuit 520 when cheating in the state 2
Driving method.The gate line for taking the driving method of 8 phases to have 8 is in the state 2.Wherein 8/2 in preliminary filling area II,
8/2 in the area IV to be closed, be equivalent to behind the position of hole 4 (preliminary filling area II) with enter to cheat before position 4 (should areas be closed
IV).Entering the state 2 when cheating, gate line corresponding to the gate line drive circuit 520 when across different transparent electrodes 400
Number difference when, will occur even if the In-cell touch display panel 210 when not touching, the initial data obtained is also
The situation that can be morphed.
Similarly, when the gate line drive circuit 520 takes the driving method of 6 phases, 6 gate lines is had and are in this
State 2.Wherein 3 in preliminary filling area II, 3 in the area IV to be closed, be equivalent to behind the position of hole 3 (preliminary filling area II) with
Enter to cheat before position 3 (should area IV be closed).Entering the state 2 when cheating, gate line when across different transparent electrodes 400 drives
When the number difference of gate line corresponding to dynamic circuit 520, it will occur not touch even if the In-cell touch display panel 210
When touching, situation that the initial data obtained can also morph.
Also that is, having the lock of X item when the gate line drive circuit 520 takes the driving method of X phase (X-phase)
Polar curve is in the state 2 (the preliminary filling area II and the area IV to be closed).Wherein X/2 item waits closing at this in preliminary filling area II, the X/2 item
Closed zone IV is equivalent to behind the position of hole X/2 item (preliminary filling area II) and enters to cheat X/2 item before position (should area IV be closed).Entering
State 2 when hole, the number of gate line corresponding to the gate line drive circuit 520 when across different transparent electrodes 400 is not
Meanwhile the initial data (raw data) obtained when the In-cell touch display panel 210 is not touched will occur also
The situation that can be morphed.
Fig. 9 is the schematic diagram of transparent electrode 400 and impacted gate line position of the invention.The gate line drive circuit
520 use 8 phase drivens.When entering to cheat position selection before Y, the gate line for being somebody's turn to do area V to be closed can enter previous transparent electricity
