Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As Figure 4-8, a kind of backlight, including glue frame 1, be arranged in the glue frame 1 light guide plate 2, be arranged on institute
The lamp bar 4 on the incidence surface of light guide plate 2 is stated, some optical films 3 are provided with the exiting surface of the light guide plate 2；The glue frame 1 by
It is provided with some screens grooves 11 on the side of nearly described one end of lamp bar 4, an at least optical film 3 in a screens groove 11 at least extending
Go out retaining structure 31.
The backlight is provided with screens groove 11 on the glue frame 1 of source ends, and the optical film 3 is to the screens groove 11
Inside extending has retaining structure 31, produces displacement to limit the optical film 3, limits working well for the displacement of optical film 3,
It is particularly useful for narrow frame or Rimless backlight.
In the present embodiment, be disposed with the exiting surface of the light guide plate 2 diffusion barrier 32, lower bright enhancement film 33 and on add lustre to
Film 34, in specific implementation, the type and quantity of the optical film 3 should according to the actual requirements depending on, should not be as limit.
In the present embodiment, the diffusion barrier 32, which extends, the first retaining structure 321, and the lower bright enhancement film 33, which extends, to be had
Second retaining structure 331, in specific implementation, each layer of optical film 3 is not limited to only each extend over out a retaining structure 31,
Multiple retaining structures 31 can also be each extended over out, this regard backlight dimensional space and the screens groove 11 quantity and
It is fixed.
Preferably, at least two optical films 3 extend retaining structure 31 into different screens grooves 11 respectively, i.e. different layers
The retaining structure 31 of optical film 3 is staggered in position, to be arranged in different screens grooves 11；Such as in the present embodiment, institute
The second retaining structure 331 for stating the retaining structure 321 of diffusion barrier 32 and first and lower bright enhancement film 33 is staggered, and is arranged on different cards
In the groove 11 of position.
Anti-dazzling screen 6 is provided with the glue frame 1, the anti-dazzling screen 6 is two-sided to have viscosity, its one backwards to the glue frame 1
Face is black, and the one side towards the glue frame 1 is black, white, silver color or other colors.
Wherein, at least the superiors' optical film 3 is pasted together with the anti-dazzling screen 6, now, if the superiors' optical film 3 with
If the anti-dazzling screen 6 is pasted together, then the superiors' optical film 3 either with or without set retaining structure 31 can, such as this reality
Apply in example, after the upper bright enhancement film 34 of the superiors is pasted together with the anti-dazzling screen 6, retaining structure 31 is not set；If
If optical film 3 outside the superiors is pasted together with the anti-dazzling screen 6, then it can be pasted by its retaining structure 31, than
In the present embodiment, the lower bright enhancement film 33 of the second layer can be pasted onto one by its second retaining structure 331 and the anti-dazzling screen 6
Rise.
Preferably, the glue frame 1 is provided with list between one end of the light guide plate 2 and the front of the light guide plate 2
Face glue 5 or double faced adhesive tape 5, the one side glue 5 have sticking one side and are pasted onto on the glue frame 1, or, the double faced adhesive tape 5 divides
It is not pasted onto on the front of the glue frame 1 and light guide plate 2, so it is prevented that the optical film 3 is shifted and sticked into described
