The utility model has the beneficial effects that: can promote the pasting effect of lamp strip, can realize moreover that the lamp strip region is lived to complete parcel, prevent that light leak and lamp shadow's problem from appearing in backlight unit, avoid reworking to appear badly, promoted the quality and the yield of product.
Description
Technical Field
The utility model relates to a display module, in particular to a light leakage-proof narrow-edge backlight module.
Background
In the display module assembly, including parts such as backlight unit, because the frame of present display module assembly is more and more narrow, lead to the pasting area of lamp strip PET in the backlight unit little, the viscidity is easy to weaken this light leak, lamp shadow scheduling problem, also takes lamp strip PET easily when tearing the backlight unit during returning to lead to the material to scrap.
Accordingly, the prior art has drawbacks and needs improvement.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a light leakage-proof narrow-edge backlight module.
The technical scheme of the utility model is as follows: the utility model provides a light leakage-proof narrow-edge backlight module, which comprises: the LED lamp strip is stuck in the integrated frame of the rubber iron through the lamp strip PET, a rubber graphite sheet is further arranged between the lamp strip PET and the integrated frame of the rubber iron, the rubber graphite sheet comprises an upper portion and a lower portion, the length of the upper portion is identical to that of the lamp strip PET, the width of the upper portion is greater than 0.2mm of that of the lamp strip PET, the lamp strip PET is correspondingly located in the area of the upper portion, the lower portion is attached to the back face of the backlight module after being bent, and the edge of the lower portion is overlapped with the lower edge of the radiating fin attached to the back face of the integrated frame of the rubber iron.
Further, the thickness of the glued graphite flake is 0.035mm.
Further, the glued graphite flake comprises: the thickness of the graphite sheet layer is 0.025mm, and the thickness of the acrylic adhesive layer is 0.01mm.
By adopting the scheme, the utility model has the beneficial effects that: can promote the pasting effect of lamp strip, can realize moreover that the lamp strip region is lived to complete parcel, prevent that light leak and lamp shadow's problem from appearing in backlight unit, avoid reworking to appear badly, promoted the quality and the yield of product.

Detailed Description
The utility model will be described in detail below with reference to the drawings and the specific embodiments.
The utility model provides a light leakage-proof narrow-edge backlight module, which comprises: an integrated frame 2 made of rubber and iron (including a rubber frame and an iron frame) and an LED lamp strip 3 (backlight FPC, welded with LEDs). LED lamp strip 3 is pasted through lamp strip PET in the integrative frame of glued iron 2, the lamp strip PET with still be equipped with between the integrative frame of glued iron 2 and take gluey graphite flake 1. The glued graphite flake 1 comprises an upper portion 11 and a lower portion 12 which are connected, the length of the upper portion 11 is the same as that of the light bar PET, the width of the upper portion 11 is larger than that of the light bar PET by 0.2mm, the light bar PET can be ensured to be located in the area of the upper portion 11, the lower portion 12 is attached to the back face of the backlight module after being bent, the edge of the lower portion 12 is overlapped with the lower edge of the radiating fin 4 attached to the back face of the glued integrated frame 2, the edge area of the lower portion 12 can be attached to the upper layer of the radiating fin 4, and the overlapped width is about 0.1mm-0.2mm. Through setting up the tape glue graphite flake 1, promoted the fixed effect of LED lamp strip.
Further, the thickness of the glued graphite flake 1 is 0.035mm.
Further, the glued graphite flake 1 comprises: the graphite sheet layer and ya keli glue layer, wherein ya keli glue layer is towards the inner wall of the integrative frame of glued iron 2, the thickness of graphite sheet layer is 0.025mm, the thickness of ya keli glue layer is 0.01mm.
To sum up, the beneficial effect of this scheme lies in: can promote the pasting effect of lamp strip, can realize moreover that the lamp strip region is lived to complete parcel, prevent that light leak and lamp shadow's problem from appearing in backlight unit, avoid reworking to appear badly, promoted the quality and the yield of product.
The foregoing description of the preferred embodiment of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
