The backlight module that example provides can strengthen backlight illumination, reduces the consumption of source current, reduces power consumption, and then reduces heat product
Raw, the service life of extended back light source.
In order to improve the uniformity of light source, between reflective list saturating formula reflector plate and backboard, can increase can be by the external world
The diaphragm that light source is broken up, as it is shown on figure 3, the structural representation of the backlight module including diffusion sheet provided for the embodiment of the present invention
Figure.
It is also preferred that the left backlight module also includes: the diffusion sheet 12 being arranged between backboard 10 and reflector plate 11.Wherein, diffusion
The size of sheet 12, type etc., can be configured according to the structure of reflector plate and backlight module, as long as be capable of the external world
Break up through the light come, make brightness more uniformly, do not limit at this.
In the specific implementation, the structure of the above-mentioned backboard being provided with the first transmission region can be configured as required,
Do not limit at this, as long as the ambient light in the external world can be made to pass through；The making material of backboard can also enter as required
Row is chosen, such as, can be transparent material, it is also possible to be nontransparent material.Introduce the backboard of two kinds of light-permeables in detail below
Structure.
The first: backboard is the structure of a flood.
In the specific implementation, as required backboard can be set to the structure of a flood, and in order to realize
The function of printing opacity, can use transparent material to make.It is also preferred that the left the material of backboard is transparent material；Backboard is one whole
The structure of layer；Alternatively non-transparent region on backboard is provided with light screening material.
Except, in above-mentioned Fig. 2, the first transmission region on backboard only includes outside the pattern of a big rectangle, the first transparent area
The pattern in territory can also be arranged as required to as by multiple little rectangles (can also be Else Rule and/or irregular shape)
Composition.
As shown in Figure 4, the plan structure schematic diagram of the second backboard provided for the embodiment of the present invention；On figure dorsulum 10
The first transmission region 101 include multiple rectangular patterns, wherein, the size of rectangular patterns and distribution situation, can basis
It is actually needed and is configured.

Dot number few.
As it is shown in figure 5, the plan structure schematic diagram of the light guide plate provided for the embodiment of the present invention；This figure be with Fig. 2 in
The plan structure schematic diagram of the light guide plate that a kind of backboard is corresponding, the first transmission region being i.e. arranged on backboard only includes one greatly
The pattern of rectangle, Regional Representative's the first transmission region that in figure, dotted line is enclosed, the initial point of Lycoperdon polymorphum Vitt represents the site on light guide plate.
Due to the network point distribution on light guide plate sparse time, brightness is partially dark, and when network point distribution is intensive, brightness is the brightest.Thus
In order to make the brightness uniformity after light guide plate, in unit are, with the first transmission region corresponding region on light guide plate 13
Dot number less, and the dot number corresponding with the lighttight region on backboard is more.
In the specific implementation, however it is not limited to the only distribution schematic diagram of above-mentioned a kind of light guide plate mesh point, wherein site is thin
Close, size etc. can be configured according to the pattern of the first transmission region on backboard, can not limit at this.
In the specific implementation, importing external environmental light, as additional source of light, can directly improve the brightness of backlight module.Typically
In the case of, when extraneous environmental light intensity, backlight module need to be lightened；When external environmental light is weak, backlight module need to be dimmed.And work as
During external environment light intensity, the ambient light just imported is the strongest；When external environmental light is weak, import external environmental light the most weak；
Import external environmental light to be very beneficial for being adjusted the brightness of display device according to the change of external environment brightness.
Based on same inventive concept, embodiments providing a kind of display device, this display device includes the present invention
The above-mentioned backlight module that embodiment provides.Owing to the principle of this display device solution problem is similar to above-mentioned backlight module, therefore
The enforcement of this backlight module may refer to the enforcement of above-mentioned display floater, repeats no more in place of repetition.
As shown in Figure 6, the structural representation of the display device including casing provided for the embodiment of the present invention；It is also preferred that the left
Display device also includes: is arranged on backlight module 1 outermost and has the casing 14 of the second transmission region 141.
In the specific implementation, display device also includes being provided with the second transmission region 141 in casing 14, and casing 14, with
Just light can pass through the second transmission region 141 in casing, and the first transmission region 101 on backboard, incides display
Panel.
Wherein, in order to ensure that the light passed through can make full use of, it is also preferred that the left the first transmission region 101 to be positioned at second saturating
In the orthographic projection on backboard of the light region 141.The size of the i.e. first transmission region 101 is not more than the chi of the second transmission region 141
Very little.As shown in Figure 6, the first transmission region 101 and the second transmission region 141 can be set to the pattern of formed objects, it is possible to
The pattern of ratio the first transmission region 101 to be arranged by the pattern of the second transmission region 141 is big.
In the specific implementation, display device is except being separate two single structures shown in Fig. 6, it is also possible to arrange
For backboard and casing one structure, it is also preferred that the left display device be backboard and casing one structure, the first transmission region 101
It is same pattern with the second transmission region 141.If display device is backboard and the structure of casing one, then have only to arrange one
The region of printing opacity, concrete set-up mode may refer to setting of the first transmission region in the introduction of above-mentioned backlight module
Put.
In sum, in the embodiment of the present invention, the reflector plate of backlight module is single formula reflector plate thoroughly, it is possible to achieve extraneous ring
Border light is unidirectional through reflector plate by the first transmission region on backboard, is incident to display floater, can be as auxiliary Non-energy-consumption
Light source；And the light that the light source of backlight unit sends cannot pass through reflector plate, the most substantially completely used by display floater, permissible
It is effectively improved brightness and the adjustability of backlight, and then reduces the power consumption of backlight module.Meanwhile, this structure used unit structure is tight
Gather, simple easily installation, take volume little, required cost is relatively low.
Obviously, those skilled in the art can carry out various change and the modification essence without deviating from the present invention to the present invention
