The corresponding bottom incidence surface is set, and the secondary light source corresponds to the top incidence surface and set, and first light source includes setting
In the first FPC and some first LEDs being welded on first FPC, the secondary light source bag
Include the second FPC and some second LEDs being welded on second FPC, first light source with
Secondary light source, which is separately controlled, to be lighted.
Further, first FPC and second FPC carry out Darkening process, and described the
One FPC forms light shield layer with the second flexible circuitry plate surface.
Further, the top incidence surface is located at described this side of rectangle vacancy.
Further, the light guide plate is provided with some sites, and it includes some the on first exiting surface
One site and some second sites on second exiting surface, first site are upward by the LED of lower section first
The second exiting surface of side progressively becomes close, and second site progressively becomes close to the right by the LED of left side first.
Further, first site and the second site are rounded, and first site and second site are big
It is small equal.
Further, the special-shaped backlight module of energy-conservation also includes：Backboard, the reflector plate in the backboard and set
Optical diaphragm group on the light guide plate, the light guide plate is interior located at the backboard and is located at the reflector plate and blooming piece
Between group.
Further, second LED is 2.
Using such scheme, the utility model provides a kind of special-shaped backlight module of energy-conservation, is set up above the first exiting surface
Second exiting surface, lighting and extinguishing for the first exiting surface and the second exiting surface can be individually controlled, when needing to check the date
When time, weather forecast or incoming information etc., it is not necessary to it is full frame to light, the second exiting surface only need to be lighted, power consumption can be reduced,
Electricity is greatlyd save, when needing full screen display, the first exiting surface and the second exiting surface are all lighted.And this product is different
Type structure design, product structure design space is saved, can meet the needs of market is to product differentiation aspect, and by using
Brand-new net-pont design, to ensure the uniformity of luminance of whole screen.
