Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight, the anti-dazzling screen of this backlight does not cover above FPC completely, but local complexity is in FPC side, can the thickness of the Lights section on effective thinning FPC, namely remove the anti-dazzling screen of source ends upper, be conducive to the thinning further of backlight.
Technical problem to be solved in the utility model is achieved by the following technical programs:
The utility model provides a kind of backlight, comprises glue frame, light guide plate, the FPC be arranged in glue frame, described FPC be pasted onto above described glue frame and light guide plate; Be disposed with diffusion barrier, lower bright enhancement film, upper bright enhancement film above described light guide plate, described diffusion barrier, lower bright enhancement film and upper bright enhancement film are all positioned at described FPC side; Be provided with anti-dazzling screen above described upper bright enhancement film, this anti-dazzling screen extends and is pasted onto above the side of close described diffusion barrier on described FPC.
Further, described anti-dazzling screen is black and white glue or black glue or black elargol.
Further, also reflector plate is provided with below described glue frame.
Further, described diffusion barrier is provided with shading adhesive tape, and described shading adhesive tape is near described FPC side.
Further, described shading adhesive tape is black adhesive tape.
Further, described FPC is provided with at least one light source.
Further, be provided with a diaphragm above described FPC, described diaphragm side and described anti-dazzling screen partly overlap, and opposite side extends to glue frame side.
Further, described diaphragm is two-sided noncohesive diaphragm.
Further, described diaphragm is the sticking diaphragm of lower surface.
The utility model additionally provides a kind of liquid crystal display module, comprises above-mentioned backlight.
The utility model has following beneficial effect: existing anti-dazzling screen is for cover above FPC completely, and anti-dazzling screen of the present utility model is that local complexity is in FPC side, can the thickness of the Lights section on effective thinning FPC, namely remove the anti-dazzling screen of source ends upper, be conducive to the thinning further of backlight; The back side is had to the backlight of brandreth, when source ends structure allows, by raising source ends protrusion height (height of increase is exactly the anti-dazzling screen thickness saved), the gap of light source and reflector plate can be strengthened, improve the reliability of product further.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of prior art backlight;
The partial sectional view of Fig. 2 embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
Please refer to Fig. 1, Fig. 1 is the upper partial sectional view near source ends of backlight 1 ' in prior art, this backlight 1 ' at least comprises FPC13 ' and covers the anti-dazzling screen 15 ' of FPC13 ' top completely, light source 14 ' one end on FPC13 ' is protruded, and anti-dazzling screen 15 ' covers this projection completely, add the thickness of backlight.And along with liquid crystal display module is toward ultra-thin future development, its each parts, also thinning, reduce further for the height adopting thin polaroid protocols call source ends to protrude.
Please refer to Fig. 2, near the partial sectional view of light source 14 end on the backlight 1 that Fig. 2 provides for the utility model, this backlight 1 comprises glue frame 11, light guide plate 12, FPC13, at least one light source 14; Described light guide plate 12 is arranged in described glue frame 11, and glue frame 11 side of described light guide plate 12 is provided with at least one U-shaped groove; Described light source 14 is fixedly connected on FPC13, and this light source 14 is contained in described U-shaped groove, and described light source 14 preferably but be not defined as LED light source 14; Described FPC13 is pasted onto above described glue frame 11 and light guide plate 12 by double faced adhesive tape 131; Be disposed with diffusion barrier 16, lower bright enhancement film 18 and upper bright enhancement film 17 above described light guide plate 12, described diffusion barrier 16, lower bright enhancement film 18 and upper bright enhancement film 17 are all positioned at described FPC13 side; Be provided with anti-dazzling screen 15 above described upper bright enhancement film 17, this anti-dazzling screen 15 extends above the side of also local complexity close described diffusion barrier 16 on described FPC13 near one end of described FPC13.Described anti-dazzling screen 15 does not cover the top of described light source 14.Described anti-dazzling screen 15 preferably but be not defined as black and white glue or black glue or black elargol.
Be provided with reflector plate 20 below described glue frame 11, this reflector plate 20 is fixedly connected with described glue frame 11 by double faced adhesive tape 111.
Be provided with shading adhesive tape 161 near diffusion barrier 16 side of described FPC13, this shading adhesive tape can play the effect that restriction bright enhancement film down offsets, and prevents bright enhancement film to be shifted.Preferably but be not defined as black adhesive tape, black adhesive tape can extinction, reduces hot spot, improves effect for described shading adhesive tape 161.The thickness of described shading adhesive tape 161 is less than or equal to the thickness sum of described lower bright enhancement film 18 and upper bright enhancement film 17.
Be coated with a diaphragm 19 above described FPC13, its material can be PET or other, mainly play shield lights, prevent light from penetrating away from glass, affect display effect.Described diaphragm 19 side and described anti-dazzling screen 15 partly overlap, and opposite side extends to glue frame 11 side.Described diaphragm 19 can be two-sided noncohesive diaphragm 19, can also be the sticking diaphragm 19 of lower surface.
The back side is had to the backlight 1 of brandreth, light source 14 and reflector plate 20 are apart from time near, and owing to manufacturing and assembly error, light source 14 may be pressed onto reflector plate 20 and cause occurring during failtests the problem of reflector plate 20 fold.Adopt backlight 1 of the present utility model, when source ends structure allows, by raising light source 14 protrusion height (height of increase is exactly anti-dazzling screen 15 thickness saved), light source 14 and the gap of reflector plate 20 can be strengthened, improve the reliability of product further.
Anti-dazzling screen 15 is covered FPC13 comprehensively and is adjusted to local complexity by backlight 1 of the present utility model, (thickness of saving is with anti-dazzling screen 15 varied in thickness used to save the thickness of anti-dazzling screen 15, that conventional is 0.05 ~ 0.06mm, but be not limited to this), reduce light source 14 side protrusion height, be conducive to collocation and use ultra-thin glass polaroid, be conducive to the further ultrathin of backlight and liquid crystal display module.
The utility model additionally provides a kind of liquid crystal display module, comprises arbitrary above-mentioned backlight, due to the height that the backlight used protrudes by reducing source ends further, is conducive to the thinning further of module and display effect.
The above embodiment only have expressed embodiment of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; in every case the technical scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection domain of the present utility model.
