Enough reduce the display difference between the first static pixels and dynamic pixel so that the display effect of whole display panel is more preferably equal
It is even.
Above-mentioned pixel-driving circuit 201 is described in detail below.
Specifically, as shown in Fig. 2 being provided with pixel electrode 202 in each pixel cell 20 on display panel.Herein
On the basis of, the pixel-driving circuit 201 in the pixel cell 20 can include the first transistor T1 and second transistor T2.
Wherein, the first transistor T1 the first pole connection grid line 10, grid connection additional signal lines 12, the second pole and second
Transistor T2 grid is connected.
Second transistor T2 the first pole connection data wire 11, the second pole is connected with pixel electrode 202.
It should be noted that above-mentioned the first transistor T1 and second transistor T2 can be N-type transistor, or P
Transistor npn npn.And the first of above-mentioned transistor extremely can be source electrode, second can be extremely drain electrode;Or, first extremely drains, the
Two extremely source electrodes.The present invention is not limited this.
So, the signal that additional signal lines 12 are exported can control the first transistor T1 conducting, and when the first crystalline substance
When body pipe T1 is turned on, the scanning signal on grid line 10 can be just exported to second transistor T2, so that by second transistor T2
Conducting, the data-signal Vdata that data wire 11 is inputted is exported to pixel electrode 202 by second transistor T2, to the picture
Plain electrode 202 is charged, to cause the electric field controls pixel list between pixel electrode 202 and public electrode (not shown)
Liquid crystal molecule in member 20 enters horizontal deflection, and control backlight goes out light, to realize the display of different gray scales.
It follows that when the frequency of the input signal of additional signal lines 12 can control the first transistor T1 in preset time P
Interior conducting number of times.In the case, when the first transistor T1 is turned on, the frequency for the scanning signal that grid line 10 is inputted can be controlled
The conducting number of times of the second transistor T2 in a preset time is made, so as to control in a preset time P, with second crystalline substance
The pixel electrode 202 that body pipe T2 is connected receives the input data signal Vdata of data wire 11 number of times, i.e., can control the pixel
The charging times of electrode 202.
Specifically, as shown in figure 3, in a preset time P, the signal frequency with second frequency F2 is that have first
3 times of frequency F1 output signal frequencies, and the 3rd frequency F3 is between first frequency F1 and second frequency F2.Therefore, upper
State in preset time P, when additional signal lines 12 drive the first transistor T1 using second frequency F2 signal, the first transistor
T1 opening times are additional signal lines 12 using three times during first frequency F1 signal driving the first transistor T1, using the
During three frequency F3 signal driving the first transistor T1, the first transistor T1 opening times between using first frequency F1 with adopting
With between second frequency F2.Similarly the control second transistor of grid line 10 T2 mode is same as above.Therefore in above-mentioned preset time P
Interior, the frequency of grid line 10 and the input signal of additional signal lines 12 is higher, and pixel electrode 202 is in the preset time in pixel cell 20
In P, the number of times being electrically charged is also more, so as to show that the power consumption of needs is also larger.
It can similarly obtain, when the signal frequency that grid line 10 or additional signal lines 12 are inputted is relatively low, pixel in pixel cell 20
Electrode 202 is in preset time P, and the number of times being electrically charged is also fewer, so as to show that the power consumption of needs is also smaller.Therefore, for
For dynamic pixel 02, additional signal lines 12 and grid line 10 are required to input high-frequency signal, such as letter with second frequency F2
Number when, in order to which the pixel-driving circuit ensured in dynamic pixel 02 can be opened in time so that data-signal Vdata can be timely
Export to the dynamic pixel 02.For the first static pixels 101, when additional signal lines 12 and grid line 10, to be required to input low
Any one input in frequency signal, such as signal with first frequency F1, or additional signal lines 12 and grid line 10 is above-mentioned
During first frequency F1 signal, the power consumption of the first static pixels 101 of driving can be reduced, is dropped using the 3rd frequency F1 signal
The principle of the second static pixels 102 of low driving is ibid.Due to (including the first static pixels 101 and second static of static pixels 01
Pixel 102) display data in scheduled time P will not change, therefore work as less using leakage current in pixel cell
During TFT, even if low-power consumption driving causes the charging times of pixel cell to reduce, it still can ensure the electricity being filled with pixel cell
Lotus has stronger holding capacity, so that the picture that static pixels 01 are shown within the above-mentioned scheduled time will not be by shadow
Ring.
However, for the reduction display power consumption on the basis of the display quality of display picture is not influenceed, for dynamic pixel
For 02, because display data changes, it is therefore desirable to by the first transistor T1 in dynamic pixel 02 and second transistor T2
Conducting in time, to cause the display data of change to be inputted by way of data wire 11 is with data-signal Vdata, in time to pixel
Electrode 202, so as to change the deflection angle of the corresponding liquid crystal molecule of dynamic pixel 02, realizes the change for showing gray scale.So,
Grid line 10 or additional signal lines 12 need the signal of the input upper frequency of pixel-driving circuit 201 into the pixel cell, example
60Hz~120Hz signal can be used as.So as to avoid, when signal frequency is less than 60Hz, causing above-mentioned crystal
Pipe on-off times are relatively low so that the not timely writing pixel electrodes 202 of the data-signal Vdata of change.However, when signal frequency is big
When 120Hz, although data-signal Vdata writing speed can be improved, but it can cause to show being substantially improved for power consumption, no
Beneficial to the design of low energy consumption product.
In addition, for above-mentioned first static pixels 01, grid line 10 or additional signal lines 12 are needed to its pixel driver
Circuit 201 inputs the signal of lower frequency, for example, can typically use and be more than 0Hz, the signal less than or equal to 60Hz.So as to
Avoid, when signal frequency is more than 60Hz, causing to show the rising of power consumption when driving static region, being unfavorable for reducing the work(of product
Consumption.
Further, the concrete structure that driving source 100 is carried out is illustrated below.Specifically, as shown in Fig. 2
The display panel can also include the first decoder 30, the second decoder 40 and clock controller 50.
Wherein, clock controller 50 is connected with the first decoder 30 and the second decoder 40, for being shown in a frame picture
Before, determine that each pixel cell 20 is dynamic pixel 02 or static pixels 01 in preset time P, and by pixel cell 20
Horizontal address information (Y1, Y2, Y3 ...) and longitudinal address information (X1, X2, X3 ...) are respectively sent to the first decoder 30
With the second decoder 40.
First decoder 30 is also connected with grid line 10, for being solved to the horizontal address information (Y1, Y2, Y3 ...)
Analysis so that clock controller 50 is by the grid line 10 that matches with horizontal address information (Y1, Y2, Y3 ...), with first frequency
The pixel-driving circuit 201 that F1, second frequency F2 or the 3rd frequency F3 drivings are connected with the grid line 10.
Second decoder 40 is also connected with additional signal lines 12, for being solved to longitudinal address information (X1, X2, X3 ...)
Analysis so that clock controller 50 by the additional signal lines 12 that match with longitudinal address information (X1, X2, X3 ...), with
The pixel-driving circuit 201 that first frequency F1, second frequency F2 or the 3rd frequency F3 drivings are connected with the additional signal lines 12.
So, can be respectively to the horizontal address of clock controller 50 by the first encoder 30 and second encoder 40
Information (Y1, Y2, Y3 ...) and longitudinal address information (X1, X2, X3 ...) are parsed, so that clock controller
50 are directed to the static pixels 01 (including the first static pixels 101 and second static pixels 102) or dynamic pixel 02 of diverse location,
The signal of corresponding frequencies is exported to its pixel-driving circuit 201.
It should be noted that because the first encoder 30 is connected with grid line 10, therefore by clock controller 50 to first
The address information that encoder 30 is exported is referred to as horizontal address information (Y1, Y2, Y3 ...).And second encoder 40 and additional signal
Line 12 is connected, thus by the address information that clock controller 50 is exported to second encoder 40 be referred to as longitudinal address information (X1,
X2、X3……).Therefore the above-mentioned horizontal and vertical different coding device that is merely representative of is believed to the different address of different signal wire output
Breath.Transmission direction to address information is not limited.For example, being revolved when by the direction of grid line in Fig. 2 10 and additional signal lines 12
Turn after 90 °, horizontal address information (Y1, Y2, Y3 ...) is inputted along longitudinal arrangement along the longitudinal direction by the first encoder 30
Grid line 10, and longitudinal address information (X1, X2, X3 ...) can in transverse direction be inputted by second encoder 40 it is transversely arranged
Additional signal lines 12.
In the case, for all grid lines 10 in display panel, generally require and gradually scan, and to all attached
Plus signal line 12 and the general opening simultaneously of data wire 11.Therefore, as shown in figure 4, it is first static to work as in one-row pixels unit
During pixel 101 (such as fourth line L4 pixel cells), above-mentioned time schedule controller 50 can be by being connected with the row pixel cell
Grid line 10 pixel-driving circuit 201 of the row all pixels unit 20 is driven with first frequency F1.And time schedule controller 50 can
So that the pixel-driving circuit of the row pixel cell 20 is driven with first frequency F1 or second frequency F2 by additional signal lines 12
201.So, for static pixels 01, at least one in additional signal lines 12 and grid line 10 can input low frequency letter
Number, so as to reduce the power consumption of driving static pixels 01.
Or, when there is at least one to be dynamic pixel 02 in one-row pixels unit, remaining is the first static pixels 101
When (such as fifth line L5 pixel cells), above-mentioned time schedule controller 50 can be by the grid line 10 that is connected with the row pixel cell
The pixel-driving circuit 201 of the row all pixels unit is driven with second frequency F2.And above-mentioned time schedule controller 50 can pass through
Additional signal lines drive the pixel-driving circuit 201 of dynamic pixel 02 in the row pixel cell with second frequency F2, and with first
Frequency F1 drives the pixel-driving circuit 202 of static pixels 01 in the row pixel cell.So, on the one hand, for static state
For pixel 01, at least one in additional signal lines 12 and grid line 10 can input low frequency signal, quiet so as to reduce driving
The power consumption of state pixel 01.On the other hand, for dynamic pixel 02, additional signal lines 12 and grid line 10 input high frequency letter
Number, it is ensured that dynamic pixel 02 can normally be shown.
In addition, as shown in figure 4, it is (such as the second row L2 pixel lists of the second static pixels 102 to work as in one-row pixels unit
Member) when, above-mentioned time schedule controller 50 can be somebody's turn to do by the grid line 10 being connected with the row pixel cell with the 3rd frequency F3 drivings
The pixel-driving circuit 201 of row all pixels unit.And above-mentioned time schedule controller 50 can be by additional signal lines 12 with first
Frequency F1 or second frequency F2 drive the pixel-driving circuit 201 of the row all pixels unit.So, on the one hand for quiet
For state pixel 01, at least one in additional signal lines 12 and grid line 10 can input low frequency signal (the 3rd frequency F3), so that
The power consumption of driving static pixels 01 can be reduced.On the other hand, due to the pixel-driving circuit of the second static pixels 102 of driving
201 the 3rd frequency is between first frequency F1 and second frequency F2, so the charging times of the second static pixels 102 are more than
First static pixels 101, keep the ability and display effect of discrepancy electric charge in pixel electrode also compared with the first static pixels 101
It is good, so as to reduce the display difference between the first static pixels 101 and dynamic pixel 02 so that entirely display panel is aobvious
Show better uniform.
Or, when there is at least one to be dynamic pixel 02 in one-row pixels unit, remaining is (the example of the second static pixels 102
Such as the third line L3 pixel cells) when, above-mentioned time schedule controller 50 can by the grid line 10 that is connected with the row pixel cell with
Second frequency F2 drives the pixel-driving circuit 201 of the row all pixels unit.And above-mentioned time schedule controller 50 can be by attached
Plus signal line 12 drives the pixel-driving circuit 201 of dynamic pixel 02 in the row pixel cell with second frequency F2, and with the 3rd
Frequency F3 drives the pixel-driving circuit 202 of the second static pixels 102 in the row pixel cell.So, on the one hand, for
For second static pixels 102, at least one in additional signal lines 12 and grid line 10 can input low frequency signal (the 3rd frequency
F3), so as to reduce driving static pixels 01 power consumption.On the other hand, for dynamic pixel 02, additional signal lines 12
With the equal input high-frequency signal of grid line 10, it is ensured that dynamic pixel 02 can normally be shown.Another aspect, due to the static picture of driving second
3rd frequency of the pixel-driving circuit 201 of element 102 is between first frequency F1 and second frequency F2, so the second static picture
The charging times of element 102 are more than the first static pixels 101, keep the ability and display effect of discrepancy electric charge in pixel electrode
It is good compared with the first static pixels 101, so as to reduce the display difference between the first static pixels 101 and dynamic pixel 02, make
The display effect for obtaining whole display panel is more preferably uniform.
From the foregoing, for the first row L1 pixel cells, because the quantity of dynamic pixel 01 is more, therefore this
A line L1 pixel cells may be constructed a dynamic area G1.For the second row L2 and the third line L3 pixel cells, due to
The quantity of second static pixels 102 is more, thus the second row L2 and the third line L3 pixel cells can respectively constitute it is another
Second static region G2.For fourth line L4 or fifth line L5 pixel cell, due to the quantity of the first static pixels 101
It is more, therefore fourth line L4 or fifth line L5 pixel cell may be constructed the first static region G3.Wherein above-mentioned dynamic area
G1, two second static region G2, G2 ' and the first static region G3 distribution situation can be as shown in Figure 5.
So, when to second skip zone G2, G2 ' inputs away from dynamic area G1 successively, for drive this
The signal frequency of the pixel-driving circuit 201 of each pixel cell is successively decreased successively in two skip zone G2, G2 '.I.e. as shown in figure 5,
Second static region G2 ', the second static region G2 are successively away from dynamic area G1, then every in the second static region G2 ' of driving
The signal of the pixel-driving circuit 201 of individual pixel cell, the pixel driver for driving each pixel cell in the second static region G2
The signal frequency of circuit 201 is successively decreased successively.So that the second static region G2 ' of driving signal frequency is with driving dynamic area G1's
Second frequency F2 is approached so that the second static region G2 of driving signal frequency and the first static region G3 of driving first frequency
F1 is approached.It is aobvious between dynamic area G1 and the first static region G3 so as to gradually be homogenized by multiple second static region G2
Show difference.
Below in conjunction with Fig. 6 a-6d, in Fig. 2 exemplified by the different pixel cell (A, B, C, D) in position, to above-mentioned driving side
Formula is described in detail.Wherein, pixel cell A is dynamic pixel 02, and pixel cell B is quiet positioned at dynamic pixel 01 and first
The second static pixels 102 between state pixel 101, rest of pixels unit is the first static pixels 101.
For pixel cell A, because the pixel cell is dynamic pixel 02, therefore additional signal lines 12 are with such as Fig. 3
Shown second frequency F2 driving pixel cells A pixel-driving circuit 201.In addition, pixel cell A, and with the pixel list
First A is located at the pixel cell with a line, such as pixel unit B be required to the grid line 10 that is connected jointly by the row pixel cell with
Second frequency F2 drives the pixel-driving circuit 201 of the row pixel cell 20.
Specifically as shown in Figure 6 a, clock controller 50 is by the longitudinal direction of the pixel cell A additional signal lines 12 being connected
Address information X1 is sent to the second decoder 40, and second decoder, 40 couples of longitudinal direction address information X1 are parsed so that clock
Controller 50 drives the row pixel by the additional signal lines 12 matched with above-mentioned longitudinal address information X1 with second frequency F2
Unit A pixel-driving circuit 201 so that the first transistor T1 is turned on.
In addition, clock controller 50 will be sent in the horizontal address information Y1 of the pixel cell A grid lines 10 being connected
One decoder 30, first decoder, 30 couples of transverse direction address information Y1 are parsed so that clock controller 50 by with it is above-mentioned
The grid line 10 that horizontal address information Y1 matches, row pixel cell A pixel-driving circuit 201 is driven with second frequency F2,
So that second transistor T2 is turned on.
In the case, pixel-driving circuit 201 is opened, because second frequency F2 frequency is higher, therefore pixel cell A
Middle the first transistor T1 and second transistor T2 the opening number of times in preset time P are relatively more, so when display data exists
When constantly changing in above-mentioned preset time P, data wire 11 can be by data voltage Vdata inputs in time to pixel cell A.
For pixel cell B, although the pixel cell be the second static pixels 102, but because pixel cell B with
Pixel cell A is connected with same grid line 10.Therefore pixel cell B same as above is also required to by common with pixel cell A
The grid line 10 of connection drives the pixel-driving circuit 201 of the row pixel cell 20 with second frequency F2.And it is used as the second static picture
The pixel cell B of element 102, in order to realize the charging times of lower frequency, additional signal lines 12 can be with the as shown in Figure 3 the 3rd
Frequency F3 driving pixel cells B pixel-driving circuit 201.
Specifically as shown in Figure 6 b, clock controller 50 is by the longitudinal direction of the pixel cell B additional signal lines 12 being connected
Address information X2 is sent to the second decoder 40, and second decoder, 40 couples of longitudinal direction address information X2 are parsed so that clock
Controller 50 drives the row pixel by the additional signal lines 12 matched with above-mentioned longitudinal address information X2 with the 3rd frequency F3
The pixel-driving circuit 201 of unit B so that the first transistor T1 is turned on.
In addition, clock controller 50 will be sent in the horizontal address information Y1 of the pixel cell B grid lines 10 being connected
One decoder 30, first decoder, 30 couples of transverse direction address information Y1 are parsed so that clock controller 50 by with it is above-mentioned
The grid line 10 that horizontal address information Y1 matches, row pixel cell B pixel-driving circuit 201 is driven with second frequency F2,
So that second transistor T2 is turned on.
In the case, pixel-driving circuit 201 is opened, although pixel cell B second transistor T2 and pixel cell A
In second transistor T2 connection sames grid line 10, into respective pixel cell second transistor T2 input upper frequency
Signal.But for pixel cell B second transistor T2, only when pixel cell B the first transistor T1 is turned on
When, the second transistor T2 can be turned on.Because pixel cell B the first transistor T1 grids receive the 3rd frequency F3's
Signal, therefore the first transistor T1 conducting number of times is less than the first transistor T1 in pixel cell A.Therefore pixel cell B
Second transistor T2 conducting number of times again smaller than the second transistor T2 in pixel cell A.So above-mentioned type of drive can
Reduce the conducting number of times of transistor, so as to reduce display power consumption.In addition as TFT less using leakage current in pixel cell B,
Even if pixel cell B charging times reduce, it still can ensure that the electric charge being filled with pixel cell has stronger holding energy
Power, so that the picture of display is unaffected in the above-mentioned scheduled time P of the second static pixels 102.
For pixel cell C, because the pixel cell D being located in Fig. 2 with pixel cell C with a line is first quiet
State pixel 101, therefore pixel cell C and pixel cell D are required to the grid line 10 connected jointly by the row pixel cell with
One frequency F1 drives the pixel-driving circuit 201 of the row pixel cell 20.
In the case, specifically as fig. 6 c, the additional signal that clock controller 50 will be connected in pixel cell C
Longitudinal address information X1 of line 12 is sent to the second decoder 40, and second decoder, 40 couples of longitudinal direction address information X1 are solved
Analysis so that clock controller 50 is by the additional signal lines 12 that match with above-mentioned longitudinal address information X1, with second frequency F2
Drive row pixel cell C pixel-driving circuit 201 so that the first transistor T1 is turned on.Or, can also by with it is above-mentioned
The additional signal lines 12 that longitudinal address information X1 matches, row pixel cell C pixel driver electricity is driven with first frequency F1
Road 201 so that the first transistor T1 is turned on.
In addition, clock controller 50 will be sent in the horizontal address information Y2 of the pixel cell C grid lines 10 being connected
One decoder 30, first decoder, 30 couples of transverse direction address information Y2 are parsed so that clock controller 50 by with it is above-mentioned
The grid line 10 that horizontal address information Y2 matches, row pixel cell C pixel-driving circuit 201 is driven with first frequency F1,
So that second transistor T2 is turned on.
Because first frequency F1 frequency is less than second frequency F2.The first transistor in therefore pixel cell C can similarly be obtained
The opening number of times of T1 and second transistor T2 in preset time P, for pixel cell A, and pixel cell B compared with
It is few.Therefore for the pixel cell using the less TFT of leakage current, above-mentioned type of drive can equally show ensureing picture
Show that reduction shows power consumption not by the case of considerable influence.
For pixel cell D, because it is also required to pass through with pixel cell C positioned at same a line, therefore pixel cell D
The grid line 10 that the row pixel cell is connected jointly drives the pixel-driving circuit 201 of the row pixel cell 20 with first frequency F1.
In the case, so as shown in fig 6d, the additional signal lines that clock controller 50 will be connected in pixel cell D
12 longitudinal address information X2 is sent to the second decoder 40, and second decoder, 40 couples of longitudinal direction address information X2 are parsed,
So that clock controller 50 is driven by the additional signal lines 12 matched with above-mentioned longitudinal address information X2 with first frequency F1
Row pixel cell D pixel-driving circuit 201 so that the first transistor T1 is turned on.Or, can also by with above-mentioned longitudinal direction
The additional signal lines 12 that address information X2 matches, row pixel cell D pixel-driving circuit is driven with second frequency F2
201 so that the first transistor T1 is turned on.
In addition, clock controller 50 will be sent in the horizontal address information Y2 of the pixel cell D grid lines 10 being connected
One decoder 30, first decoder, 30 couples of transverse direction address information Y2 are parsed so that clock controller 50 by with it is above-mentioned
The grid line 10 that horizontal address information Y2 matches, row pixel cell D pixel-driving circuit 201 is driven with first frequency F1,
So that second transistor T2 is turned on.Similarly driving pixel cell D power consumption is again smaller than the power consumption for driving pixel cell A.
In summary, secondly driving pixel cell A power consumption highest, driving pixel cell B power consumption drives pixel cell
C's and pixel cell D is least in power-consuming.
On this basis, the display panel is as shown in Fig. 2 driving source 100 can also include source electrode driver 60, the source electrode

The embodiment of the present invention provides a kind of method for driving any one above-mentioned display panel, as shown in fig. 7, described
Driving method includes:
S101, before a frame picture is shown, determine each pixel cell 20 be in preset time P dynamic pixel 02 or
Static pixels 01.The static pixels 01 can include the first static pixels 101 and the second static pixels 102.Wherein, dynamic pixel
01 and first has a pre-determined distance H between static pixels 101, and the second static pixels 102 are located at the first static pixels 101 and dynamic
Between state pixel 01.
Specifically, above-mentioned static pixels 01 and the specific partition process of dynamic pixel 02 can be:
Before a frame picture is shown, the number of repetition of i frame display datas is more than or equal to j pixel cell 20 before continuous
Referred to as static pixels, will it is continuous before the numbers of repetition of i frame display datas be less than j pixel cell 20 and be referred to as dynamic pixel.1 < j
≤ i, i, j are positive integer.

Drive circuit 201.
S103, by additional signal lines 12 and grid line 10 with second frequency F2 drive dynamic pixel 02 pixel-driving circuit
201。
S104, by additional signal lines 12 and/or grid line 10 with the 3rd frequency F3 drive the second static pixels 102 pixel
Drive circuit 201.
It should be noted that the 3rd frequency F3 is more than first frequency F1, less than second frequency F2.And above-mentioned first frequency F1
More than or equal to 1HZ, less than or equal to 60HZ, it can avoid, when signal frequency is more than 60Hz, causing to show during driving static pixels
The rising of power consumption, is unfavorable for reducing the power consumption of product.In addition, second frequency F2 is more than 60HZ, less than or equal to 120HZ, it can keep away
Exempt from when signal frequency be less than 60Hz when, cause above-mentioned transistor switch number of times relatively low so that the data-signal Vdata of change not and
When writing pixel electrode 202.Also, when signal frequency is more than 120Hz, although data-signal Vdata write-in can be improved
Speed, but can cause to show being substantially improved for power consumption, it is unfavorable for the design of low energy consumption product.
The present invention is not limited above-mentioned steps S102, S103 and S104 step sequencing.For example, step
Additional signal lines 12 in S102, step S103 and step S104 can input signal simultaneously, after this, step S102, step
Grid line 10 in rapid S103 and step S104 is while input signal.
S105, pixel-driving circuit 201 are opened, the input data line signal Vdata of data wire 11, in pixel cell 20
Pixel electrode 202 is charged.
Because during actual displayed, the display data of the one part of pixel unit on display panel all can in each frame
Change, and the display data of another part pixel cell can keep constant in continuous multiple frames.Therefore driving source can be with
According to the situation of change of display data (including at least two frames) in the given time, a frame pixel cell is divided into static pixels
And dynamic pixel.Wherein its display data of static pixels can be repeated in the given time, and dynamic pixel is sent out in the given time
Changing.The static pixels include the first static pixels and the second static pixels, and the second static pixels are between the first static picture
Between element and dynamic pixel.
On this basis, for the first static pixels, driving source is by additional signal lines and/or grid line with the first frequency
Rate drives the pixel-driving circuit of first static pixels;For dynamic pixel, additional signal lines and grid line are with
Two frequencies drive the pixel-driving circuit of dynamic pixel;For the second static pixels, additional signal lines and/or grid line are with
Three frequencies drive the pixel-driving circuit of the second static pixels.Because the 3rd frequency is more than first frequency, less than second frequency, this
Sample one, may be such that the charging of the second static pixels between dynamic pixel and the first static pixels.But it is due to first quiet
The display data of state pixel in the given time is repeated without changing, therefore when smaller using leakage current in pixel cell
TFT when, even if the charging times of pixel cell reduce, still can ensure that the electric charge that is filled with pixel cell has stronger
Holding capacity, so that the picture that the first static pixels are shown within the above-mentioned scheduled time is unaffected.And for dynamic
For state pixel, because the display data of the pixel cell can all change in each frame, it is possible to by grid line and attached
Plus signal line improves the charging times of pixel cell to the higher signal of the pixel-driving circuit incoming frequency of the pixel cell,
The data voltage being continually changing is inputted to above-mentioned pixel cell in time by data wire.And for static positioned at first
For the second static pixels between pixel and dynamic pixel, on the one hand, it remains as static pixels, so frequency is less than second
Although the signal of frequency can reduce the charging times of the second static pixels, its display effect is not interfered with.On the other hand,
The frequency of the 3rd frequency signal of the second static pixels is driven between first frequency and second frequency, so the second static picture
The charging times of element are more than the first static pixels, keep the ability and display effect of discrepancy electric charge in pixel electrode also compared with first
Static pixels are good, so as to reduce the display difference between the first static pixels and dynamic pixel.
In summary, on the one hand, due to can be by grid line and/or additional signal lines to the first static pixels and second
The relatively low signal of the pixel-driving circuit incoming frequencies of static pixels, so as to reduce the power consumption of display driving.Also, in reality
During border is shown, each frame picture all includes static pixels and dynamic pixel, therefore can reduce display drive in each frame
Dynamic power consumption, so the effect of reduction power consumption is more effective in terms of existing technologies.On the other hand, what the present invention was provided is aobvious
Show that panel all can drive dynamic pixel and static pixels to be shown in each frame, therefore do not deposit a frame dynamic menu and a frame is quiet
Instantaneous switching of the state picture in display, so as to avoid because tableaux and dynamic menu instantaneously switch the screen flash caused
Phenomenon.Another aspect, drives the frequency of the 3rd frequency signal of the second static pixels between first frequency and second frequency,
So the charging times of the second static pixels are more than the first static pixels, display effect is also good compared with the first static pixels, so as to
Enough reduce the display difference between the first static pixels and dynamic pixel so that the display effect of whole display panel is more preferably equal
It is even.
It should be noted that for all grid lines 10 in display panel, generally require and gradually scan, and to all
Additional signal lines 12 and the general opening simultaneously of data wire 11.Therefore, as shown in figure 4, it is first quiet to work as in one-row pixels unit
During state pixel 101 (such as fourth line L4 pixel cells), above-mentioned driving method includes:
First, the row all pixels unit is driven with first frequency F1 by the grid line 10 that is connected with the row pixel cell
20 pixel-driving circuit 201.
Then, the pixel of the row pixel cell 20 is driven with first frequency F1 or second frequency F2 by additional signal lines 12
Drive circuit 201.
So, for static pixels 01, at least one in additional signal lines 12 and grid line 10 can input low
Frequency signal, so as to reduce the power consumption of driving static pixels 01.
Or, when there is at least one to be dynamic pixel 02 in one-row pixels unit, remaining is the first static pixels 101
When (such as fifth line L5 pixel cells), above-mentioned driving method includes:
First, the row all pixels unit is driven with second frequency F2 by the grid line 10 that is connected with the row pixel cell
Pixel-driving circuit 201.
Then, the pixel driver of dynamic pixel 02 in the row pixel cell is driven with second frequency F2 by additional signal lines
Circuit 201, and drive with first frequency F1 the pixel-driving circuit 202 of static pixels 01 in the row pixel cell.
So, on the one hand, for static pixels 01, at least one meeting in additional signal lines 12 and grid line 10
Low frequency signal is inputted, so as to reduce the power consumption of driving static pixels 01.On the other hand, it is attached for dynamic pixel 02
Plus signal line 12 and the equal input high-frequency signal of grid line 10, it is ensured that dynamic pixel 02 can normally be shown.
In addition, when in one-row pixels unit being the second static pixels 102 (such as the second row L2 pixel cell), it is above-mentioned
Driving method includes:
First, the row all pixels unit is driven with the 3rd frequency F3 by the grid line 10 that is connected with the row pixel cell
Pixel-driving circuit 201.
Then, the picture of the row all pixels unit is driven with first frequency F1 or second frequency F2 by additional signal lines 12
Plain drive circuit 201.
So, on the one hand for static pixels 01, at least one meeting in additional signal lines 12 and grid line 10
Low frequency signal (the 3rd frequency F3) is inputted, so as to reduce the power consumption of driving static pixels 01.On the other hand, due to driving the
3rd frequency of the pixel-driving circuit 201 of two static pixels 102 is between first frequency F1 and second frequency F2, so
The charging times of two static pixels 102 are more than the ability for the electric charge that come in and gone out in the first static pixels 101, holding pixel electrode and shown
Show that effect is also good compared with the first static pixels 101, so as to reduce the display between the first static pixels 101 and dynamic pixel 02
Difference so that the display effect of whole display panel is more preferably uniform.
Or, when there is at least one to be dynamic pixel 02 in one-row pixels unit, remaining is (the example of the second static pixels 102
Such as the third line L3 pixel cells) when, above-mentioned driving method includes:
First, the row all pixels unit is driven with second frequency F2 by the grid line 10 that is connected with the row pixel cell
