In frame, first LED backlight and the second LED backlight are separately positioned on the side of the first light guide plate and the second light guide plate
Side, the reflector plate are arranged between the first light guide plate and the second light guide plate, and the diffusion barrier is pasted setting and led second
The outer side edges of tabula rasa.
In one preferred embodiment of the utility model, LED mounting base, the LED peace are provided in the glue frame
There are two the quantity for filling seat.
In one preferred embodiment of the utility model, first LED backlight and the second LED backlight are pacified respectively
It is arranged in LED mounting base and in relative direction.
In one preferred embodiment of the utility model, the backlight of television LED light further includes backboard, the back
Plate is arranged in the bottom of the first light guide plate and is located in glue frame.
In one preferred embodiment of the utility model, first light guide plate and the second light guide plate, which are provided with, makes light
The dot pattern of reflection.
In one preferred embodiment of the utility model, the material of first light guide plate and the second light guide plate is propylene
Acid resin.
The beneficial effects of the utility model are: the backlight of television LED light of the utility model, using the double-deck opposite side entering type
Luminous form makes light uniformly be distributed in entire liquid crystal display panel, further increases the contrast of picture by double layer light guide board,
Enhance display effect.
Detailed description of the invention
