Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
It is to be understood that orientation "upper" used in the present invention, "lower" are "upper", "lower" direction in Fig. 1 and Fig. 2.
The present invention provides a kind of liquid crystal display device, and as shown in Figures 1 and 2, the liquid crystal display device includes liquid crystal
Panel 200, backlight 400 and the front frame 100 that backlight 400 is connected with liquid crystal display panel 200.Front frame 100 includes interconnecting
Cross spacing portion 110 and longitudinal spacing portion 120, longitudinal spacing portion 120 is located at the outside of liquid crystal display panel 200, and around liquid crystal
Panel 200, cross spacing portion 110 extends from the upper end in longitudinal spacing portion 120 initially towards the middle part of liquid crystal display panel 200, with position
In the top of the light-emitting surface of liquid crystal display panel 200.Wherein, the liquid crystal display device further includes gap adjusting mechanism, the gap
Regulating mechanism is used to adjust the gap between cross spacing portion 110 and the light-emitting surface of liquid crystal display panel 200.
In order to enable liquid crystal display panel 200 is securely attached together with backlight 400, it is often necessary to the transverse direction of front frame 100
Limiting section 110 closely mentions and and on the light-emitting surface of liquid crystal display panel 200.Through the inventors of the present invention discovered through researches that, if horizontal
If the engagement tension of limiting section 110 and liquid crystal display panel 200, it is easy that liquid crystal display panel 200 is caused to oppress, so that liquid crystal
Panel 200 is deformed.After liquid crystal display panel 200 is deformed, liquid crystal molecule in liquid crystal display panel also corresponding deformation, to can make
The phenomenon that at dark-state light leakage.
In liquid crystal display device provided by the present invention, the adjustable cross spacing portion 110 of gap adjusting mechanism is utilized
Gap between the light-emitting surface of liquid crystal display panel 200.
By can be seen that in Fig. 1 and Fig. 2 in Fig. 1 between cross spacing portion 110 and the light-emitting surface of liquid crystal display panel 200
Distance is greater than the distance between the light-emitting surface in cross spacing portion 110 and liquid crystal display panel 200 in Fig. 2.
When being that liquid crystal display panel 200 is in dark-state display shown in Fig. 1, the state of gap adjusting mechanism.As shown, horizontal
To between limiting section 110 and the light-emitting surface of liquid crystal display panel 200, there are biggish distances, and therefore, the light-emitting surface of liquid crystal display panel 200 is not
Again by the compressing in cross spacing portion 110, will not be deformed, therefore, the phenomenon that dark-state light leakage will not be generated.
It is shown in Fig. 2 be liquid crystal display panel 200 be in non-dark-state display when, the state of gap adjusting mechanism.As shown,
Cross spacing portion 110 is again adjacent to liquid crystal display panel 200, so as to be liquid crystal display panel 200 and backlight in the case where non-dark-state
Source 400 provides bigger attachment force, so that liquid crystal display panel 200 and backlight 400 are securely attached together.
In other words, intermittent regulation mechanism can be when liquid crystal display panel 200 be in dark-state display by cross spacing portion and liquid crystal
Gap between panel tunes up, and can be when liquid crystal display panel 200 is in the display of non-dark-state by liquid crystal display panel and cross spacing
It turns down in gap between portion.There is the phenomenon that light leakage when to can not only prevent dark-state from showing, but also may insure in liquid crystal display panel
Most of state under can be rigidly joined together with backlight.
It is to be understood that in order to make it easy to understand, being exaggerated in fig. 1 and 2 to the size of front frame 100, in reality
In the production of border, the size of front frame 100 is really not so.Also, in the display device, longitudinal spacing portion 120 is can to occur
Flexible deformation.
In the present invention, to the concrete form of gap adjusting mechanism, there is no special regulations.For example, in fig. 1 and 2
Shown in embodiment, the gap adjusting mechanism includes at least one magnetostriction component 310, the magnetostriction component
310 include magnetostriction column 313, the first electrode 311 that 313 one end of magnetostriction column is arranged in and setting in the magnetostriction
The second electrode 315 of 313 other end of column can be generated between first electrode 311 and second electrode 315 so that magnetostriction column
313 magnetic fields stretched, also, magnetostriction column 313 is between liquid crystal display panel 200 and longitudinal spacing portion 120, magnetostriction column
313 top is located at the lower section in cross spacing portion 110.
When providing voltage respectively to first electrode 311 and second electrode 315, first electrode 311 and second electrode 315 it
Between generate magnetic field so that magnetostriction column 313 extend.It, will be lateral after the elongation to a certain extent of magnetostriction column 313
Limiting section 110 jacks up, and deforms liquid crystal display panel 200 so as to prevent cross spacing portion 110 from acting on liquid crystal display panel 200.
It should be pointed out that magnetostriction column 313 is between liquid crystal display panel 200 and longitudinal spacing portion 120, and therefore, magnetic
Telescopic mast 313 is caused not generate active force to liquid crystal display panel 200 during deformation.Also, the deformation of magnetostriction column 313
It is reversible, after removing electric field, the recovery of magnetostriction column 313 to the original length, as shown in Figure 2.
In the present invention, the material of magnetostriction column is not particularly limited, as long as can be under the influence of a magnetic field
Elongation.As a kind of preferred embodiment of the invention, the material of the magnetostriction column includes Ni-Co alloy, Ni-
