Therefore the imaging for needing to cooperate 30 side of the shutter glasses that can reach stereoscopic picture plane again also needs to control the liquid by the controller 40
The running of crystal panel 10, the backlight 20 and the shutter glasses 30 is arranged in pairs or groups.
The liquid crystal display panel 10 has a plurality of data line and multi-strip scanning line, and has respective control circuit to the progress
Control, the scan line is horizontally arranged in general, and scans by the scan line of 10 the top of liquid crystal display panel to most lower
The scan line of side can be considered the generation of a left eye or right eye picture, when right and left eyes picture after whole scan lines scans through
After all generating, carry the user of the glasses 30 will visually will form a stereoscopic picture plane.When whole scan lines has been scanned
Afterwards, scanning motion can be returned to first scan line, to carry out the imaging process of next right eye or left eye picture.
The backlight 20 has multiple LED light-emitting components, to provide light source to the liquid crystal display panel 10.Preferably, the back
Tabula rasa 20 can control the luminous column with more multiple luminous scan line quantity for arranging the corresponding liquid crystal display panel 10, the controller 40
Fluorescent lifetime, to be cooperated with the scan line scanned time.The LED light-emitting component is preferably by blue light core
New-type LED composed by piece and red, green emitting phosphor, so as to provide preferable color pure for the liquid crystal display panel 10
Degree.The backlight 20 is for switching opening or closing for its backlight, and in a preferred embodiment, which can have all
Change switch, and controlled by the controller 40 with switch the backlight 20 it is luminous whether, but in other embodiments, the back
Switching switch is not necessarily had on tabula rasa 20, switching switch can be placed on the element outside the backlight 20, also or the back
Tabula rasa can be opened or closed directly by the controller 40 control.
Wherein, which further includes the light source of multiple kinds of colors, at least two face in the light source of multiple kind of color
The difference or the difference of fall time of the rise time of the luminescent waveform of the light source of color is greater than 1 millisecond (msec), for example, such as
Shown in Fig. 1 (B), the rise time of one first colour light source 21 is Tr1, fall time Tf1 in the light source；One second color
The rise time of light source 22 is Tr2, fall time Tf2, then when the difference of the rise time of two-tone light | Tr1-Tr2 | or
Person is the difference of fall time | Tf1-Tf2 | when being greater than 1 millisecond, because the reaction time of light source is slow, therefore it is of the invention to arrange in pairs or groups
Design, the 3D image presented just tend to have preferable quality.
The shutter glasses 30 have a left eyeglass lens and a right eye eyeglass, and the light transmission of each eyeglass is controllable with sequentially
Switching open and close, in a preferred embodiment, the shutter glasses 30 have one switching switch, to switch left eyeglass lens with

Time carrys out the light transmission of switching right and left eye, i.e., when the liquid crystal display panel 10 shows left eye picture, which can control the backlight
Plate 20 generates backlight, and opens the light transmission of the left eyeglass lens of the shutter glasses 30, so that the left eye of user can see the left side
Eye picture, but in another embodiment, switching switch is not necessarily had on the shutter glasses 30, switching switch can be placed in this
On element outside shutter glasses 30, also or the eyeglass light transmission of the shutter glasses 30 can directly by the controller 40 control open or
It closes.In addition, the mode that can be wirelessly transferred between the shutter glasses 30 and the controller 40 is controlled, but it is not limited to
This.
Fig. 2 (A) is the first reality for responding the first structure of slow shutter stereo picture for improving backlight of the invention
The flow chart of applying method, this method are executed by the system 1 of Fig. 1 (A).Step S21 is carried out first, which connects
A left eye or eye image data signal are received, i.e., the liquid crystal display panel 10 receives a display left eye or the instruction of eye image is believed
Number, it include the left eye to be shown or eye image data in the command signal；Step S22 is carried out later, when receiving the instruction
After signal, which controls each luminous column of the backlight 20 while opening；Step S23, the liquid crystal surface are carried out later
First scan line of plate 10 starts to be scanned, in other words, when the liquid crystal display panel 10 receives the left or right eye image document signal
Afterwards, which can control all LED light-emitting components in the backlight 20 simultaneously while shine, and wait until the backlight 20
Shine scanning that is rear or carrying out the scan line simultaneously；Later carry out step S24, continue each scan line scanning to this most
Latter scan line, so that every online pixel of scanning is started to charge to respective default voltage；Step is carried out later
S25 re-enters the left eye or eye image data, and scans since first scan line again, until the last item
When scan line starts scanned；Step S26 is carried out later, when the last item scan line starts one section after second of scanning
Between, preferably all pixels of first scan line have charged to the default voltage at this time, which controls the shutter
The left eyeglass lens light transmission or right eye eyeglass light transmission of glasses 30 are opened, in other words, after all scan lines start scanning, the controller
40, which can then control the shutter glasses 30 that user carries, opens the light transmission of left eyeglass lens or right eye eyeglass, if it carries out at present
Be left eye picture imaging, then open the light transmission of the left eyeglass lens or right eye eyeglass and close the right eye eyeglass or left eyeglass lens
Light transmission, thus the left eye or right eye of user can receive picture；Step S27 is carried out later, when the last item scan line root
After carrying out second of scanning according to left eye or right eye picture data information, which receives a right eye or left eye picture
Data information and the scanning for starting to carry out right eye or left eye picture；Carry out step S28 later, when the right eye or left eye picture most
A period of time after the completion of latter scan line is scanned, online pixel preferably is scanned in the last item and has all been charged
To the default voltage, which closes the light transmission of the left eye or right eye eyeglass of the shutter glasses 30.Step is carried out later
S29, the system 1 is according to the scanning of above-mentioned steps completion right eye or left eye picture and right eye eyeglass or the unlatching of left eyeglass lens light transmission
With closing, after left eyeglass lens and right eye eyeglass all receive corresponding image, a stereopsis is can be seen in user.
It is worth noting that, in this embodiment, which just persistently opens after opening, in other words in the scanning
The backlight 20 can also continue to open when line is scanned, therefore the backlight 20 will not have continuity fluorescent lifetime mistake after closing
Long and cause user see different eye shadows as the problem of.In addition, since left eye or right eye picture are shown after the completion of scanning
Image be not pop-off but fade away, therefore, the light transmission opening time of the left eye or right eye eyeglass will be between
First scan line is completed the scanning of left eye or right eye picture and between the last item scan line not yet completes, at the same this first
Scan line has started to carry out the scanning of right eye or left eye picture, since in scanning process, right eye picture is not possible to be imaged, because
The light transmission of this left eyeglass lens is opened at this moment will only see the left eye picture in fading away without can be appreciated that the right side formed
Eye picture.
Fig. 2 (B) is the schematic diagram of multi-strip scanning line on liquid crystal display panel 10 in Fig. 2 (A) step S21-S28 process, to make
It is bright next to have 8 scan line SL1-SL8 be illustrated with the liquid crystal display panel 10 in more detail, but actually described sweep
The quantity for retouching line is not limited to 8.
Fig. 2 (C) -2 (F) is the detailed implementation status diagram of Fig. 2 (A) process, please also refer to Fig. 2 (A) to Fig. 2 (F),
First in time T1, the scan line SL1 to SL8 is to start to be scanned to show a left eye picture, i.e. the liquid crystal
Panel 10 will carry out the formation of left eye picture, and the scan line has no the scanning for carrying out right eye picture at this time.Time T1 compared with
The good half for being close to 8.333 milliseconds (ms), and time t1 to t8 can be divided into.In the t1 time, first scan line SL1
Start the scanning of progress left eye picture imaging, the pixel on this scan line SL1 will start to charge and voltage is made to increase, should
Charging finally will charge to respective predetermined voltage, and the pixel is made to open the image document to show left eye picture, and
In time t1, the pixel of first scan line SL1 is to belong to the state just started to charge, other scan line
SL2-SL8 then still maintains the imaging (the right eye picture imaging after having scanned through) of a picture (right eye picture).In time t2
In, Article 2 scan line SL2 starts to be scanned, and the pixel on this scan line SL2 starts to charge.It is so lasting to carry out often
The scanning (time t3-t7) of scan line is to time t8, in time t8, the last item scan line SL8 start it is scanned and
Voltage rises, and the pixel on other scan line SL1-SL7 still falls within voltage and maintains state at this time, i.e., in liquid crystal transition reaction.
Later in the T2 time, the scan line SL1-SL8 will carry out the scanning of second of left eye picture, i.e., every scanning
The pixel of line SL1-SL8 charges again to show left eye picture, due to every scan line SL1-SL8 pixel when the time T1
It charges, therefore charging in time T2 again will can shorten the pixel and reach the time of predetermined voltage, furthermore such as
With time T1, time T2 is preferably 8.333 milliseconds of half, and can be divided into time t9 to t16.In time t9 to t15,
The scan line sequentially charges.In time t16, the voltage of the pixel of scan line SL1 to SL3 all has reached predetermined electricity
Pressure, and scan line SL7 is still in charging, and scan line SL8 then starts to carry out the scanning of second of left eye picture.Due in the time
In t16, the pixel of at least existing three scan line SL1-SL3 has charged to predetermined voltage and can show left eye picture
Image document, therefore the controller 40 can open the light transmission of the left eyeglass lens of the shutter glasses 30 in this time t16, allows use
The left eye of person initially receives the information of left eye picture, however actually can also be in the pixel charging of first scan line SL1
The light transmission of the left eyeglass lens is switched on after to predetermined voltage.It is noted that left eye picture is divided into T1, T2 charging, this is
For Multiple frequency design, it can make to reduce above picture with the level of charge difference below picture, keep the presentation of image more consistent.So
And the present invention also can be used under the design of non-frequency multiplication, i.e. after left eye picture will not charge twice, but the charging of left eye picture is primary
Switch to right eye picture.
Later in the T3 time, which will carry out first time right eye according to right eye picture data signal
The scanning of picture, the liquid crystal display panel 10 will start the formation of progress right eye picture at this time.In time t17, scan line SL1's
Pixel starts to carry out the charging scanning of right eye picture, can show the money of the right eye picture after charging to a predetermined voltage
Material.In time t18, Article 2 scan line SL2 starts to carry out the charging of pixel, in time t19 to t24, the scanning
Line SL1-SL8 persistently carries out the scanning of right eye picture.It is worth noting that, before time t24, because liquid crystal has the reaction time,
So liquid crystal at this time can be transformed into the voltage status of right eye picture slowly from the voltage status of left eye picture, that is, when
Between t24 a setting time before, liquid crystal has not maintained the voltage status of left eye picture, and the light transmission of the left eyeglass lens will be closed.
Left eyeglass lens light transmission close, and the scan line start carry out second of right eye picture scanning after, the right eye eyeglass
Light transmission can just open.
It is described in more detail, the backlight 20 is constantly to open, therefore LED has been avoided to shine in time T1 to T3
The element shut-in time it is too long and cause different eye picture backlights be overlapped the problem of.In addition it can be seen from the above, the shutter glasses 30
The left eyeglass lens light transmission opening time is preferably just opens after second of the scanning that all scan line SL1-SL8 all carry out left eye picture
When opening, and carrying out second of scanning due to the last item scan line SL8, first scan line SL1 charging has reached predetermined electricity
Press and can show a part of image of left eye picture, therefore user can initially receive the image, therefore in order to promote human eye
The left eyeglass lens light transmission of the brightness perceived, the shutter glasses 30 can be after first scan line SL1 carries out second scanning
It is opened after a period of time；And the left eyeglass lens light transmission shut-in time of the shutter glasses 30 is preferably in the last item scan line SL8
After carrying out a period of time after scanning second, i.e., the voltage status of left eye picture is still maintained in liquid crystal, draw being transformed into right eye
Before the voltage status in face, left eyeglass lens light transmission is closed, thus user can receive complete image data, wherein being worth
It is noted that time of the eyeglass light transmission from opening closing is actually very of short duration, therefore the vision of user itself can't
See that scan line sequentially shows the process of image, but understands the generation of direct feeling a to left-eye image.In addition, working as right and left eyes
After image all generates, user visually will form a three-dimensional image.
In addition, referring once again to Fig. 2 (F), the unlatching of left eyeglass lens light transmission or the right eye eyeglass light transmission of the shutter glasses 30
Time (as shown in the x of Fig. 2 (F)) is to account for 50 percentages (%) of this picture imaging time (as shown in the y of Fig. 2 (F)) extremely
Between 90 percentages, i.e. x/y=50-90 (%), and the opening time of the backlight 20, (backlight of the present embodiment was persistently to open
Open) 35 percentages to 100 percentages of this picture imaging time y are then accounted for, this picture imaging time y herein is the eye
Picture whole sweep time, such as Fig. 2 (F), because an embodiment is Multiple frequency design thus, therefore y is the update of a picture
Twice of time (1frame time).And Multiple frequency design is not used other, but in the embodiment for using primary frequency to design, it should
The picture only run-down of eye, then this picture imaging time y is the renewal time (1frame time) of a picture
One times.Formula is defined as follows: for shutter glasses: the time that x=left or right eye is opened in the picture, y=eye picture
The sweep time of face whole.For backlight, the time that x=backlight is opened in the picture, the picture of y=at a glance is whole
Sweep time.
Fig. 3 (A) is the second reality for responding the first structure of slow shutter stereo picture for improving backlight of the invention
The flow chart of applying method, this method are executed by the system 1 of Fig. 1 (A).Step S31 is carried out first, which connects
A left or right eye image document signal is received, i.e. the liquid crystal display panel 10 receives the left or right eye image that enable is instructed and to be shown
Data；Step S32 is carried out later, and first scan line of the liquid crystal display panel 10 starts to be scanned；Step S33 is carried out later, is held
The scanning of continuous each scan line is to the last item scan line；Step S34 is carried out later, again since first scan line
Sequentially scan；Step S35 is carried out later, when the pixel of first scan line will charge to the default voltage, the control
Device 40 opens all luminous column in the backlight 20 simultaneously；Step S36 is carried out later, it is last after the luminous column are opened
One scan line starts after carrying out second charging, which controls left eyeglass lens light transmission or the right eye of the shutter glasses 30
Eyeglass light transmission is opened, in other words, after all scan lines start to carry out second to scan, preferably in first scan line
Pixel has charged to after the default voltage (voltage status that liquid crystal has turned to left eye picture), which can then make in control
The solid shutter glasses 30 that user wears open the light transmission of left eye or right eye, if carry out at present be left eye picture at
Picture then opens the light transmission of the left eye or right eye and closes the light transmission of the right eye or left eye, and thus the left eye or right eye of user can
To receive picture；Step S37 is carried out later, after the completion of second of scanning of first scan line, first scan line
The scanning for receiving a right eye or left eye picture data information and starting progress right eye or left eye picture (carries out another picture
Scanning)；Later, step S38 is carried out, when one section after the completion of the last item scan line of the left eye or right eye picture is scanned
Between, which closes the light transmission of the left eye or right eye eyeglass of the shutter glasses 30.Later, step S39 is carried out, in the left eye
Or after right eye eyeglass light transmission is closed, which closes the backlight 20.Step S40 is carried out later, and the system 1 is according to above-mentioned
Step completes the open and close of the scanning of another right eye or left eye picture and the light transmission of right eye or left eyeglass lens, works as left eyeglass lens
And after right eye eyeglass all receives corresponding image, a stereopsis is can be seen in user.
It is worth noting that, in this embodiment, the backlight 20 and non-continuous unlatching, but it is online in first scanning
Pixel just unlatching when will charge to a default voltage, and carry out the electricity of another picture in the voltage of the last item scan line
It is closed before pressure charging.And the unlatching switch of the eyeglass light transmission is then that can just open after the backlight 20 unlatching, and preferably exist
The backlight 20 is first closed before closing, so even being that the light-emitting component of the backlight 20 can still have continuous illumination after closing
Phenomenon, user will not see, because the light transmission of eyeglass is turned off.
Fig. 3 (B) is the detailed implementation state of the backlight 20 and left eyeglass lens light transmission in Fig. 3 (A) step S31-S39 process
Schematic diagram, and please also refer to Fig. 2 (C) to 2 (E).The scanning process of right and left eyes picture is carried out in the present embodiment about scan line
It is identical with Fig. 2 (C) to 2 (E) of first embodiment, and main difference is that when being the open and close of backlight 20
Between.As shown in Fig. 2 (C) -2 (E) and Fig. 3 (B), in time t9 to t16, i.e., the picture on first scan line SL1
Before the charging of second of left eye picture of element is near completion, the light-emitting component in the backlight 20 will be turned on simultaneously, by
This can have backlight when the first scan line SL1 completes charging and shows a part portrait.And when the backlight 20 generates
After backlight, the light transmission of the left eyeglass lens of the shutter glasses 30 can be just turned on, and the light transmission of the left eyeglass lens open opportunity as
First embodiment is preferably just opened after second of the scanning that all scan line SL1-SL8 all carry out left eye or right eye picture,
Due to when the last item scan line SL8, which carries out second, to be scanned, first scan line SL1 charging have reached predetermined voltage and can

After picture is shown and after the right eye picture shows.
In general, the stereoscopic picture plane display system 100 is constantly to show multiple stereoscopic picture planes (i.e. multiple left eye pictures
And right eye picture), therefore next it will be described for the case where showing multiple stereoscopic picture planes.Since the liquid crystal display panel 100 is with more
A pixel, to make explanation illustrate below with one of pixel in more detail.
Wherein, when the pixel needs to show the left eye picture data (signal of left eye picture) or the right eye picture data
When the grayscale value of (signal of right eye picture), which can transmit a gray scale voltage to the pixel, the gray scale voltage pair
Ying Yuyi grayscale value, the pixel generate the corresponding grayscale value according to the gray scale voltage.In general liquid crystal display panel can have
One positive frame stage and a negative frame stage checker, therefore the gray scale voltage of corresponding same gray level value is in positive frame stage and negative frame
Stage will be different, which is a model in the difference of the gray scale voltage in positive frame stage and the gray scale voltage in negative frame stage
Value is enclosed, such as is equally 255 grayscale of display, the gray scale voltage in negative frame stage is 0.5V, and the gray scale voltage in positive frame stage is
15.5V, then the gray scale voltage value range of 225 grayscale is 15V.
Fig. 8 (A) is that a pixel on the liquid crystal display panel 100 user when showing first stereoscopic picture plane is experienced
Brightness change timing diagram.Brightness value shown by the pixel is in the signal of the signal and the right eye picture that show the left eye picture
It is identical, i.e., the pixel received gray scale voltage show the left eye picture signal and the right eye picture signal when have phase
Same numerical value.Such as the pixel all shows the one of the picture when signal of the signal and the right eye picture that show left eye picture
White signal.Wherein, the white signal is to make the pixel show maximum brightness.
It is worth noting that, in the case that the pixel is to show the white signal when being applied the gray scale voltage, it should
Liquid crystal display panel is to belong to vertical orientation type (Vertical aligned, VA), in other words, if the liquid crystal display panel belongs to twisted nematic
It is then one black signal of display when the pixel is applied the gray scale voltage when type (Twist Nematic, TN).In other words, to vertical
For straight alignment-type panel, which is the signal for making the pixel show maximum brightness, to stable twisted nematic panel
Speech, the black signal are the signals to make the pixel show minimum brightness.It for convenience of description, below will be with vertical orientation type
(VA) as an example.
Fig. 8 (B) is that the pixel on the liquid crystal display panel 100 user when showing second stereoscopic picture plane is experienced
Brightness change timing diagram, signal of the brightness value shown by the pixel in the signal and the right eye picture for showing the left eye picture
Shi Butong, the i.e. pixel received gray scale voltage show the left eye picture signal and the right eye picture signal when have
Different numerical value.Such as the pixel is the white signal for showing the left eye picture in the signal of display left eye picture, and the picture
Element is the black signal for showing the right eye picture in the signal of display right eye picture.And when the left eye picture and the right eye picture
Between when being inserted into the display elimination mechanism (black or grey picture), when will lead to liquid crystal display panel 100 and showing, human eye is experienced bright
Degree be relatively expected it is low, i.e., the pixel in show the left eye picture signal (white signal) received by gray scale voltage will be unable to
Reach predetermined value in one specific time, therefore the brightness that will lead to the white signal reduces.
Fig. 8 (C) is the pixel on the liquid crystal display panel 100 when showing first stereoscopic picture plane and second stereoscopic picture plane
Human eye experience brightness value and compare figure, due to the presence of the black or grey picture, the pixel is in showing the one of second stereoscopic picture plane
Generated brightness value when generated brightness value can be lower than the white signal for showing first stereoscopic picture plane when white signal,
When therefore showing that the pixel of second stereoscopic picture plane is converted into the white signal from image elimination mechanism (black or grey picture),
It will cause the too late problem of liquid crystal reaction speed.The liquid crystal display panel 100 shows first stereoscopic picture plane in switching and this is second vertical
When body picture, the drop of the white signal brightness value will interfere (white closstalk).
Preferably, in order to avoid above-mentioned problem, when the pixel is in the first display picture of first stereoscopic picture plane
One first positive frame gray scale voltage is received when being displayed in white signal, when the pixel Yu Yizheng frame stage or is received when a negative frame stage
One first negative frame gray scale voltage, the first positive frame gray scale voltage and the first negative frame gray scale voltage have one first difference, when this
Pixel shows that the pixel connects when another positive frame stage when being displayed in white signal in picture in the third of second stereoscopic picture plane
One second positive frame gray scale voltage is received, or receives one second negative frame gray scale voltage, the second positive frame grayscale when another negative frame stage
Voltage and the second negative frame gray scale voltage have one second difference, and wherein first difference is necessarily less than second difference, such as
The first positive frame gray scale voltage is 16V, which is 4V, which is 12V, the second positive frame grayscale
Voltage is 17V, which is 3V, which is 14V.Can reduce as a result, first stereoscopic picture plane with
The difference of white signal brightness value, is lowered the interference in second stereoscopic picture plane.
Wherein, the white signal of second stereoscopic picture plane is not limited to be shown by left eye picture, actually also can be by
The right eye picture shows that the positive frame gray scale voltage of the right eye picture and the difference of negative frame gray scale voltage then have to be larger than this at this time
The positive frame gray scale voltage of the right eye picture of first stereoscopic picture plane and the difference of negative frame gray scale voltage.
It is worth noting that, above situation is that the liquid crystal display panel belongs to vertical orientation type (VA), field those skilled in the art can
If know that the liquid crystal display panel belongs to stable twisted nematic (TN), which is one black signal of display.
In addition, although the second structure of the invention is to be inserted into display elimination after the left eye picture and right eye picture are shown
Mechanism (black or grey picture), the i.e. left eye of user just can be appreciated that the black or grey picture after seeing left eye picture or right eye picture
Face, but actually the black or grey picture also can be inserted before the left eye picture and right eye picture, that is, the left side of user
Eye will first see the black or grey picture, then see left eye picture.
As a result, using the display elimination mechanism is inserted into, user will not see different pictures due to backlight postpones to dissipate
Remaining picture, and then solve the problems, such as backlight response slowly and caused by afterimage interference.
It is only for the sake of illustration for above-described embodiment, and the interest field that the present invention is advocated certainly should be with right
Subject to described in claimed range, not just the above examples.
