Embodiment
To make the purpose of the present invention, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings to embodiment of the present invention
It is described in further detail.
Embodiment one
As shown in figure 1, the invention provides a kind of back light unit 1, for realizing the requirement to the local controlled light of back light unit 1, together
When maintain backlight it is bright it is dark mutually turn in the case of gentle transition.The back light unit 1 is described including luminescence component 11 and for controlling
Multiple backlight driving units 12 of the bright dark situation of luminescence component, specifically, as shown in Fig. 2 the luminescence component 11 includes substrate
111 and the array LED 112 that is electrically connected on substrate 111., can be so that luminescence component 11 to be divided to be more after array LED 112 is set
Individual control zone, each region can include multiple LED112, it is preferable that the LED112 quantity in each region is equal；It is so luminous
The can of component 11 requires brightness or the switch of subregion regulation backlight according to display, so as to realize wanting for local controlled light
Ask.Specifically, the luminescence component 11 divides for multiple control zones, the area of the N of each control zone control zone adjacent with its line/mono-
Domain and put the region of the N2 of adjacent control zone/mono- and be electrically connected at same backlight driving unit；The span of the N is 2
To 4；Wherein, line adjacent area represents there is a conllinear region with some control zone, general to be in the control zone
Left and right or the adjacent area of upper and lower both sides, point adjacent area represent the region for having a concurrent with some control zone, typically
That is the adjacent area of four diagonal positions in the control zone.So, each control zone is controlled in backlight driving unit 12
Bright dark situation when, the region of the N2 of the region of the N of control zone adjacent with its line/mono- and the adjacent control zone of point/mono- is also simultaneously
Controlled, it is bright it is dark mutually turn when, i.e., originally highlighted region switchs to dark, and adjacent original dark region switchs to highlight,
There will be a transitional region, be always maintained at highlighted state, so as to there is a bright dark transition region mutually turned so that picture
Switching is gentler, realizes more preferable display effect.In the present embodiment, the value of the N is preferably 3.
In the present embodiment, as shown in figure 3, the luminescence component 11 divides for 4x6 control zone, by taking C3 areas as an example, C3 areas
Control zone C2 areas adjacent with its line, C4 areas, B3 areas, each 1/3rd region in D3 areas, adjacent control zone B2 areas, B4 are put with it
Area, D2 areas, each 1/9th region in D4 areas are commonly connected to same backlight driving unit 12-C3, i.e., when opening C3 areas,
C2 areas, C4 areas, B3 areas, each 1/3rd regions and B2 areas in D3 areas, B4 areas, D2 areas, each 1/9th region in D4 areas are also same
Shi Kaiqi, light-emitting zone are the dotted box portion shown in Fig. 3.Further, as shown in figure 4, occur it is bright it is dark mutually turn when, i.e.,
When C3 areas switch to dark by highlighted, when C4 areas switch to highlighted by dark, due to C4 areas control zone adjacent with its line each three/
Each 1/9th region of one region and the adjacent control zone of point is also controlled by a backlight driving unit 12-C4 simultaneously, i.e. C3 areas
A control overlapping region, i.e. Fig. 4 shadow regions be present with C4 areas and its periphery adjacent area, this region when C3 areas are highlighted by
It is highlighted in being maintained by same backlight driving unit 12-C3 controls, when when C3 areas switch to dark, C4 areas switch to highlighted, due to
Equally maintained by same backlight driving unit 12-C4 controls highlighted, realized in C3 areas and C4 areas bright dark when mutually turning with C4 areas
It there is one and be always maintained at highlighted transitional region, so that the bright dark transition that mutually turns is gentle, effectively solve because backlight becomes
Change it is excessively obvious and the problem of influence display effect.Specifically, in the present embodiment, backlight driving unit 12 controls luminescence component
11 control zone realized by control electric current size, it is bright it is dark mutually turn when, in backlight driving unit 12-C3 control C3 areas
By it is highlighted switch to dark when, can reduce C2 areas adjacent thereto of C3 areas, C4 areas, B3 areas, D3 areas each 1/3rd regions and B2 areas,
B4 areas, D2 areas, D4 areas each 1/9th region electric current, so as to reduce brightness, and due to backlight driving unit 12-C4 simultaneously
When control C4 areas switch to highlighted by dark, the electric current of C4 areas and its corresponding adjacent area can be improved, so as to simultaneously by 12-C3 and
The size of current of the overlapping region Ji Tu4 shadow regions of 12-C4 controls is constant, so as to be always maintained at highlighted state.
It should be noted that the present invention does not limit for the number of partitions and mode of luminescence component 11, luminescence component
11 specific number of partitions can be made reasonably according to the quantity of array LED 112 and the driveability of backlight driving unit 12
Distribution.In the present embodiment, each backlight driving unit 12 is correspondingly connected to a control zone setting, described for controlling
The bright dark situation in the region of the N2 of the region of the N of control zone control zone adjacent with its line/mono- and the adjacent control zone of point/mono-.When
So, each backlight driving unit 12 can also be correspondingly connected to multiple control zones according to its driveability, for controlling respectively
The region of the N of each control zone control zone adjacent with its line of system/mono- and put the bright of the region of the N2 of adjacent control zone/mono-
Dark situation；The backlight driving unit for being connected to multiple control zones is provided with multiple connectivity ports, is connected to multiple control zones, can
To control multiple control zones simultaneously and export different drive signals so that the bright dark situation of multiple control zones is different.
