In addition, backlight BL1 is provided after State Transferring is stablized in the liquid crystal lattice of liquid crystal display panel 14, ghost can be avoided
Phenomenon.In in practical operation, it can also be able to liquid crystal lattice and completed the State Transferring of certain percentage to regard under acceptable specification
To have stablized.The liquid crystal reaction time is defined as the time required to liquid crystal lattice conversion (such as from standard-sized sheet to fully closed).If during a scanning
The time span of section (such as first scanning period TP1) is aobvious to be less than the liquid crystal reaction time, therefore in principle, in first scanning
Backlight is not provided in period TP1, because now the liquid crystal lattice of liquid crystal display panel 14 fail in stable state, even not
Close to stable state.In the present embodiment, backlight BL1 control modules 12 control backlight module 16 from cycle time sequence TS
Very first time t1 rise provide, very first time t1 fall the 3rd scan period TP3 end point E3, exceeded well over the cycle (also
I.e. its time span for scanning period TP1~TP4 and vertical blanking interval VB1~VB4 the totalling time) half.In
General scenario, end point E1 and very first time t1 time difference dt1 is more than the liquid crystal reaction time, therefore user can be in viewing area
The almost image without ghost is watched on domain 142；But the present invention is not limited.For example, even if t1 is not less than week the very first time
The half of phase, if foregoing time difference dt1 can also watch the shadow of no ghost still greater than the liquid crystal reaction time, user
Picture.
Also, in the present embodiment, very first time t1 falls in the 3rd end point E3 for scanning period TP3 (or meanings the 3rd
Vertical blanking interval VB3 initial point), backlight BL1 continues to the second time t2 in the 4th vertical blanking interval VB4, such as
This backlight BL1 at least continue for an a scanning period TP4 and vertical blanking interval VB3.From the point of view of the opposing party, backlight BL1
From (the 3rd scanning period i.e. in the present embodiment penultimate scanning period in a plurality of scanning periods TP1~TP4
TP3 end point E3) starts to provide.In in implementation, control module 12 also the plurality of scanning period TP1 of controlling back light module 16
Backlight BL1 is provided after the end point E3 of penultimate scanning period (i.e. the 3rd scanning period TP3) in~TP4.Separately
Outside, in the present embodiment, the second time t2 is fallen within the 4th vertical blanking interval VB4, in practical operation, also can be extended down to most
The end point at the latter vertical blanking interval (the 4th vertical blanking interval VB4 i.e. in the present embodiment) (is tied to this cycle
Beam).
In addition, in the present embodiment, backlight BL1 has luminous intensity L1, and luminous intensity L1 can adjust.Work as image brilliance
When insufficient, luminous intensity L1 can be also improved.When required image brilliance is constant, luminous intensity L1 can be improved to shorten backlight BL1
Time (that is, very first time t1 and the second time t2 time difference) is provided.In in practical operation, luminous intensity L1 tune
Whole permeable user's setting, or the scope of collocation backlight BL1 extensions perform automatically.For example, in Fig. 2, backlight BL1 is control
Module 12 controls backlight module 16 to be provided from the very first time t1 in cycle time sequence TS between the second time t2, in image
Under the constant requirement of brightness, backlight BL1 is adjusted to backlight BL2 (shown in dotted line), and wherein backlight BL2 is from time t3 to time t4
Between provide, backlight BL2 luminous intensity L2 is higher than luminous intensity L1, luminous intensity L1 and time t1 to the second time t2 time
Poor dt1 product is equal to luminous intensity L2 and time t3, t4 time difference dt2 product.In other words, very first time t1 to second
Time t2 time difference is one predetermined with luminous intensity L1 (or time t3, t4 time difference dt2 and luminous intensity L2) product
Value.But the present invention is not limited.In addition, in general, under the requirement that image brilliance can be satisfied, very first time t1's prolongs
Backlight BL1 is contributed to be provided after the liquid stable lattice of liquid crystal display panel 14 afterwards.In addition, luminous intensity L1 and time difference dt1
Also it respectively can independently be adjusted by user, alleviate ghost phenomena, while meet brightness demand.In addition, in practical operation,
Module 12 is controlled to control backlight module 16 also can be after first end point E1 for scanning period TP1, there is provided to divide with backlight BL1
Another backlight BL3 (being represented by dotted lines in the 2nd figure) opened, also contribute to lift brightness.
Supplementary notes, if very first time t1 falls in first end point E1 for scanning period TP1, LCD
The liquid crystal lattice of the plate 14 corresponding subregion of viewing area 142 (i.e. close to scanning area during end point E1) may still not change to
Stable state, after causing backlight BL1 to provide, the subregion (during for example with horizontal sweep, i.e. the bottom of viewing area 142
Region) image may still have ghost phenomena.On the other hand, backlight BL1 can be limited in the initial point S2 of second scanning period TP2
There is provided afterwards, such as very first time t1 falls in initial point S2, it is foregoing not change to steady in first vertical blanking interval VB1
Conversion can be continued to stable state in the case of backlight BL1 not yet occurs by determining the liquid crystal lattice of state, with when the backlight BL1, energy
Remove ghost problem.If foregoing do not change to the liquid crystal lattice of stable state can not be all changed to stable state, can at least reduce not
Change to the liquid crystal lattice quantity of stable state, also just alleviate ghost phenomena.
In addition, when display device 1 is actually used, continuous image that liquid crystal display panel 14 is shown in viewing area 142
Partial dynamic image and part static image, such as online game may be included, its image, which is shown, is also generally divided into upper and lower twoth area
The image (such as the movement of game, interaction etc.) that game is carried out immediately is presented in domain, wherein upper area, and it belongs to dynamic shadow
Picture；Information (such as the ability value of game, mutual exchanged messages, games system of the player in game is presented in lower zone
Information of offer etc.), it belongs to static image.In general, dynamic image because pixel color changes greatly, be easier to reflect it is residual
Shadow problem；Conversely, static image is smaller because pixel color changes, ghost phenomena is not easy to be noticeable.Therefore, backlight BL1 is carried
The decision of the initial point (i.e. very first time t1) of confession can also utilize this characteristic and extend forward, allow the ghost of static image to show
As to increase the time range (can also improve image brilliance) of backlight BL1 offers.It is the display to refer to Fig. 4 and Fig. 5, Fig. 4

FD2 corresponds to relative quiescent image.Control module 12 controls backlight module 16 to start to provide backlight BL1 initial point (when i.e. first
Between t1) corresponding second image data section FD2 (initial point), now, user can watch liquid crystal display panel 14 in
The corresponding first image data section FD1 of first area 142a displays relative dynamic image, and liquid crystal display panel 142 is in second
The corresponding second image data section FD2 of region 142b displays relative quiescent image.If when backlight BL1 occurs, although liquid crystal
Display panel 14 still has a non-complete stability of liquid crystal lattice, but these liquid crystal lattice are predominantly located at lower section (such as corresponding second area
142b), and shower is relative quiescent image on second area 142b, and image change is smaller, therefore ghost phenomena regards to user
Influence in feel is also small.In addition, when backlight BL1 occurs, though have part correspond to first area 142a liquid crystal lattice it is incomplete
It is stable, but the ratio for accounting for whole first area 142a is still small, then and ghost phenomena caused by the partial liquid crystal lattice is watched user
For whole first area 142a, still belong to slight.
Supplementary notes, in the present embodiment, very first time t1 falls to be scanned in period TP2 at second, but the present invention
It is not limited.In addition, in the present embodiment, when very first time t1, corresponding first area 142a liquid crystal lattice are at least
A scanning period and a vertical blanking interval (i.e. a quarter in cycle in the present embodiment) are crossed, if the liquid crystal reacts
Between enough hours (such as the means in liquid crystal reaction time are reduced through customary means), be, for example, less than four points of the cycle in the present embodiment
One of, then the liquid crystal lattice for now corresponding to first area 142a have been stablized, in the relative dynamic image shown on the 142a of first area
There is no ghost problem in principle.In in practical operation, if by very first time t1 controls when scanning in period TP3 for the 3rd, it is right
First area 142a liquid crystal lattice are answered at least to have been subjected to two scanning periods and two vertical blanking intervals (i.e. in the present embodiment
The half in cycle), it more can easily promote corresponding first area 142a liquid crystal lattice to enter stable state, to provide user
Relative dynamic image without ghost.Explanation is supplemented, is influenceed based on the foregoing ghost using relative quiescent image less
Characteristic, in practical operation, if initial part also shows relative quiescent image above viewing area 142, it will can also carry on the back
The second time t2 that light BL1 terminates was postponed in first scanning period into next cycle, and corresponding foregoing aobvious in scanning
Before showing that the image data of the top relative quiescent image of region 142 terminates；Thereby, image brilliance can be further added by.In addition, in reality
In operation, control module 12 controls backlight module 16 also can be after first end point E1 for scanning period TP1, there is provided with the back of the body
Another backlight BL3 (being represented by dotted lines in Fig. 4) separated light BL1, also contribute to lift brightness.
In addition, be supplemented explanation, in previous embodiment, single a cycle (i.e. it is the plurality of scan period TP1~
4) in, in principle, control module 12 is provided which identical picture image data FD to liquid crystal display panel 14, but the present invention not with
