3rd electricity of the 4th backlight 72, the second circuit board 73 of control the 3rd backlight 71 and control the 4th backlight 72
Road plate 74；
The incidence surface 413 of 3rd backlight 71 and first light guide plate is oppositely arranged, the 4th backlight 72
It is oppositely arranged with the incidence surface 423 of second light guide plate.
Wherein, because the first light guide plate 41 and the second light guide plate 42 are wedge shape, in order that obtaining the incident more light of incidence surface
Source, therefore, the width of the incidence surface 413 of the first light guide plate 41 are more than the width in the 3rd face 414, the incidence surface of the second light guide plate 42
423 width is more than the width of the fourth face 424.
The technical scheme of the embodiment of the present invention has the advantages that：
The set-up mode of light source module and light guide plate provided in an embodiment of the present invention enters light using bilateral, relative to embodiment
The mode of three single-sided illuminations, has disperseed the heat excessively concentrated during single-sided illumination, has improved the radiating of double-sided display backlight module
Performance, improves reliability.
In the light source module and the set-up mode of light guide plate shown in the Fig. 6 of above-described embodiment three and example IV Fig. 7, work as use
During single-sided illumination mode shown in Fig. 6, it is only necessary to which a first circuit board 63 controls the first backlight 61 and the second backlight 62,
The control to backlight exiting surface is realized, the structure of backlight module is simplified；Enter light mode when using the bilateral shown in Fig. 7
When, because the backlight positioned at the same side in original Fig. 6 has been dispersed in both sides, it is therefore desirable to which single circuit board is right respectively
It is controlled, and such backlight is dispersed in both sides, has disperseed the heat excessively concentrated during single-sided illumination, improves two-sided aobvious
Show the heat dispersion of backlight module, improve reliability.
Embodiment five
On the basis of embodiment three or example IV, the embodiment of the present invention additionally provides backlight module, and the present embodiment exists
Based on being illustrated on the basis of example IV, the 3rd light source 71 in the backlight module be LED light bar or for institute
State the corresponding multiple LEDs (lamp bar) of display subregion of the first light guide plate；4th backlight 72 be LED light bar or for

As shown in figure 8, the 3rd light source 71 in the backlight module is corresponding multiple with the display subregion of the first light guide plate
LED (lamp bar), the 4th backlight 72 is multiple LEDs (lamp bar) corresponding with the display subregion of second light guide plate, its
The middle display number of partitions can be understood as pixel, certainly because pixel is smaller, set more complicated with pixel quantity identical LED,
Accordingly it is also possible to the multiple pixels of display subregion correspondence are set in advance in, for example, the display number of partitions of the first light guide plate is N
It is individual, " subregion 1, subregion 2 ... subregion N " (N is the positive integer more than or equal to 1), the display subregion of the second light guide plate in such as Fig. 8
Number is N number of, " subregion 1, subregion 2 ... subregion N " (N is the positive integer more than or equal to 1), so, in respective partition in such as Fig. 8
For it is dark when, second circuit board 73 only needs to control LED of the 3rd backlight 71 respective partition etc. to close, relative to arrangement one
Whole LED light bar, solves the unconspicuous problem of comparison of light and shade.
In addition, it is preferable for the thermal diffusivity of whole backlight module, in the outside of second circuit board 73 and tertiary circuit plate 74
The first heat sink strip 81 and the second heat sink strip 82, wherein face of the area of heat sink strip 81 compared with second circuit board 73 are correspondingly provided with respectively
Identical or more than second circuit board 73 the area of product；The area of heat sink strip 82 is identical compared with the area of tertiary circuit plate 74 or more than
The area of three-circuit plate 74.
The technical scheme of the embodiment of the present invention has the advantages that：
When above-mentioned light source is LED light bar, installation steps can be simplified；When for the display subregion with the first light guide plate it is corresponding
During multiple LEDs, per showing that it is bright dark that subregion is individually controlled by the mainboard chip in circuit board all the way, according to the bright dark control of picture
The LED's of each display subregion is bright dark, and comparison of light and shade is obvious, while also reducing power consumption.
