Detailed description of the invention
The utility model provides a kind of backlight, comprises a backlight module and is fitted in the reflector plate below this backlight module by gum; Described gum is have extensible the first gum being fitted in the flanging portion of this backlight module side, or the second gum for being formed by coating binder.When existing diaphragm technique restriction, by the flanging portion exceeding narrow frame backlight module periphery being folded into the mode of side, solve the impact of gum width limit restriction; Or adopt the mode of gluing, utilize the framework of reflector plate or backlight module as its substrate layer, when gum narrows, because adhesive layer thickeies, be conducive to the fixing of reflector plate; Be conducive to designing and producing of narrow frame backlight.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Embodiment 1
Please refer to Fig. 2,3, which show the utility model back light source structure schematic diagram.This backlight comprises backlight module and is fitted in the reflector plate 11 below this backlight module by the first gum 111; Described first gum 111 has the extensible flanging portion 112 being fitted in this backlight module side.This backlight also comprises the anti-dazzling screen 18 be fitted in above this backlight module.When described anti-dazzling screen 18 be the sticking black glue of one side tool or black and white glue time, its side towards described backlight module has viscosity, side away from described backlight module is black, described anti-dazzling screen 18 has the extensible kink 181 being fitted in described flanging portion 112, to cover the surface viscosity in described flanging portion 112; When described anti-dazzling screen 18 be the sticking black glue of two-sided tool or black and white glue time, its side away from described backlight module is black, can be fitted with diaphragm to cover surface viscosity in flanging portion 112, as PET (such as 0.01mm thickness).
Described backlight module comprises a framework 12 with spatial accommodation, the light guide plate 13 being positioned at this spatial accommodation, is positioned at a luminescence unit 14 of the spatial accommodation near described light guide plate 13 incidence surface side, is positioned at the blooming of described light guide plate 13 exiting surface side.Described framework 12 is provided with the spatial accommodation for carrying described light guide plate 13; Described light guide plate 13 has an incidence surface and an exiting surface; Described blooming comprises diffusion barrier 15, lower bright enhancement film 16 and upper bright enhancement film 17, and described diffusion barrier 15, lower bright enhancement film 16 and upper bright enhancement film 17 are sequentially laminated on above described light guide plate 13 exiting surface.
It should be noted that, described flanging portion 112 can also be two symmetrical flangings, three flangings or four flangings.The present embodiment is preferably three flangings, usually only needs left and right and luminescence unit 14 opposite of backlight module to need to have flanging, places luminescence unit 14 1 end spaces enough, do not need to be greater than backlight module periphery and be folded into side.Described kink 181 can be two symmetrical bendings, also can be three bendings, can also be four bendings, be preferably three bendings, usually left and right and luminescence unit 14 opposite of backlight module is only needed to need to have bending, place luminescence unit 14 1 end spaces enough, do not need to be greater than backlight module periphery and be folded into side.
Make further improvements, at the back side of described backlight and side spray black ink, in case leak-stopping light.
The present embodiment backlight is by separately gum 111 and reflector plate 11, and this gum 111 has flanging portion 112 to side edge bending to be fitted in the side of backlight module, solves the impact of gum 111 width limit restriction, is conducive to the realization of narrow border structure.
Embodiment 2
Please refer to Fig. 4, which show the utility model back light source structure schematic diagram.This backlight comprises backlight module and is fitted in the reflector plate 21 below this backlight module by the second gum 211; Described second gum 211 is formed by coating binder, does not adopt the double faced adhesive tape of band substrate layer.The double faced adhesive tape of current employing is all the structure of three layers, substrate layer and upper and lower surface adhesive, and usually thick double faced adhesive tape is more eager to excel in whatever one does than thin viscosity.Therefore in same thickness situation, if do not have substrate layer, the amount of adhesive just increases, and improves the viscosity of double faced adhesive tape.Consider adhesive to be directly coated on reflector plate 21, reflector plate 21 is equivalent to the substrate layer of double faced adhesive tape, and when gum 211 narrowed width, because glue amount increases, viscosity can be better.
Described backlight module comprises a framework 22 with spatial accommodation, the light guide plate 23 being positioned at this spatial accommodation, the luminescence unit 24 being positioned at the spatial accommodation near described light guide plate 23 incidence surface side, the blooming being positioned at described light guide plate 23 exiting surface side and the anti-dazzling screen 28 be fitted in above this backlight module.Described framework 22 is provided with the spatial accommodation for carrying described light guide plate 23; Described light guide plate 23 has an incidence surface and an exiting surface; Described blooming comprises diffusion barrier 25, lower bright enhancement film 26 and upper bright enhancement film 27, and described diffusion barrier 25, lower bright enhancement film 26 and upper bright enhancement film 27 are sequentially laminated on above described light guide plate 23 exiting surface
Make further improvements, at the back side of described backlight and side spray black ink, in case leak-stopping light.
The present embodiment backlight adopts the mode of gluing, utilizes the framework 22 of reflector plate 21 or backlight module as its substrate layer, when gum 211 narrows, because adhesive layer thickeies, is conducive to the fixing of reflector plate 21; Be conducive to designing and producing of narrow frame backlight.
