LED lamp bar 500.
In the present embodiment, metal frame 100 is chase, and in other embodiments, metal frame can also be other materials
Matter is made, such as aluminum etc..
Heat conduction glue-line 300 and reflector plate 200 interval are arranged, or abut against with reflector plate 200.Can also
Being interpreted as, heat conduction glue-line 300 is set up in parallel with reflector plate 200, and has gap each other, or leads
Hot glue layer 300 is set up in parallel with reflector plate 200, and end located adjacent one another abuts against.Further, lead
Hot glue layer 300 part covers at least part of region of LED 520, i.e. heat conduction glue-line 300 is completely covered LED
Lamp 520, or heat conduction glue-line 300 part covering LED 520.
LED lamp bar 500 includes flexible PCB 510 and the LED 520 being arranged on flexible PCB,
Wherein, LED 520 is connected with metal frame by heat conduction glue-line 300 away from the side of flexible PCB.
It is pointed out that in the present embodiment, flexible PCB 510 covers the edge of light guide plate 400, i.e. covers
Light guide plate 400 is away from the side of metal frame 100, concrete, and flexible PCB 510 is by shading glue or double
Face sticker is located on light guide plate 400.In other embodiments, the edge of flexible PCB 510 can also with lead
The edge of tabula rasa 400 is concordant.
Above-mentioned backlight assembly 10 compares traditional backlight assembly, owing to LED 520 is by heat conduction glue-line 300
Abut with metal frame 100 rather than abutted with metal frame 100 by reflector plate 200, and then make LED
520 heats produced, pass to quickly to metal frame 100, accelerate the heat dispersion of backlight assembly 10,
Improve the stability in use of backlight assembly 10, and extend its service life.
Additionally, due to flexible PCB 510 covers the edge of light guide plate 400, make the peace of LED lamp bar 500
Dress fastness is higher, and is avoided that light leak.

Arrange owing to heat conduction glue-line 300 and reflector plate 200 are spaced, it is to avoid heat conduction glue-line 300 and reflector plate 200
Interfere when assembling.Additionally, due to first end 210 with and the LED that abuts against of light guide plate 400
Distance between 520 is less than 2mm, it is possible to ensures the reflecting effect of reflector plate 200, thus does not affect backlight
The display effect of assembly 10.
In other embodiments, heat conduction glue-line 300 abuts against with the first end 210 of reflector plate 200, and the
One end 210 is concordant with the second end 410.The most now, LED 520 is adjacent to the end of light guide plate 400
Concordant adjacent to the end of light guide plate 400 with heat conduction glue-line 300, and reflector plate 200 is adjacent to LED 520
End is concordant adjacent to the end of LED 520 with light guide plate 400, and respectively with heat conduction glue-line 300 and LED
Lamp 520 abuts against.
According to practical situation, in other embodiments, when the second end 410 than first end 210 closer to LED
During lamp 520, heat conduction glue-line 300 can also extend between light guide plate 400 and metal frame 100, and with
One end 210 interval is arranged, or abuts against.
It is pointed out that according to practical situation, first end 210 can also extend to LED 520 with
Between metal frame 100, now, the first end 210 of reflector plate 200 covers the part district of LED 520
Territory, another part region is covered by heat conduction glue-line 300.
Further, in the present embodiment, LED 520 is multiple, and multiple LED 520 form a line.
Further, heat conduction glue-line 300 is strip, and the LED 520 formed a line is respectively positioned on strip heat conduction glue-line 300
On.It is also understood that heat conduction glue-line 300 is one, multiple LED 520 may be contained within this heat-conducting glue
On layer 300.In such manner, it is possible to improve the heat-conducting effect of backlight assembly 10.
In other embodiments, the quantity of heat conduction glue-line 300 can also be identical with LED 520 quantity, each
The corresponding LED 520 of heat conduction glue-line 300 is arranged.I.e. to may be contained within one right with it for each LED 520
On the heat conduction glue-line 300 answered.
A kind of display device, including above-mentioned backlight assembly 10.
