Description
Technical field
Art of display device manufacture is the utility model is related to, concretely relates to a kind of backlight and its modular structure.
Background technology
Liquid panel technique development is maked rapid progress, and specification is constantly lifted, to matched backlight module requirement
Constantly lifted.At present, main flow resolution ratio has reached full HD (FHD, Full High Definition) rank, 4K2K
Product is also shown up prominently, and the lifting of resolution ratio causes the decline of penetrance, and this just proposes higher requirement to backlight illumination.Separately
Outside, the theory of " thinner and lighter " requires that the weight of backlight module must also make moderate progress.Fig. 1 is existing modular structure schematic diagram,
Existing modular structure includes backboard 10, LED 70, reflector plate 20, light guide plate 30, diaphragm group 40, glue frame 60 and liquid crystal panel
50, existing backlight module is stacked using backboard 10 and glue frame 60 as support member, and LED 70 is located at light guide plate 30 and glue frame
Between 60.Fig. 2 is the propagation path of light figure simplified in existing backlight, and light is sent by LED 70, because LED 70 can not be with leading
Tabula rasa 30 is matched completely, and part light is spilt into up to the inwall of glue frame 60 through light guide plate 30, is further reflected；Light is in the inwall of glue frame 60
Reflection be diffusing reflection, light guide plate 30 is again introduced into by a reflected light part, in the position for having LED, a part of reflected light by
It is blocked and is lost in the propagation of light；There is no the position of LED, due to certain distance be present between glue frame 60 and light guide plate 30,
A part of light can be lost in air borne.In addition, the use of backboard and glue frame not only increases cost, module weight can not also
Further mitigate.
Utility model content
To solve the above problems, the utility model proposes a kind of backing structure, the exiting surface in light guide plate close to incident side
Cut groove, by by LED be embedded in light guide plate groove, and then reflector plate can the above folding parcel light guide plate, using light guide plate for support,
Backboard and glue frame are not used, it is not only cost-effective so as to simplify modular structure, mitigate module weight, optics can also be improved
Utilization rate, increase brightness, optimization optics taste.
The utility model provides a kind of backing structure, and it includes reflector plate, light guide plate, LED light bar and each layer optical film
Piece, light conducting plate structure include incident side, bottom surface, the exiting surface relative with bottom surface and the side with plane perpendicular, the leaded light
Plate is provided with multiple grooves close to the exiting surface of incident side, and the LED is embedded in the groove；The reflector plate parcel is guide-lighting
The side and bottom surface of plate.
Further, LED light bar includes flexible PCB and fixed multiple LED lamp beads on circuit boards, described after assembling
LED lamp bead is fixed in the light guide plate groove.
Further, the thickness of the LED lamp bead is not more than the depth of the light guide plate groove.
Further, the reflector plate is in bending after assembling, the exiting surface of the reflector plate wrapping portion light guide plate device.
Further, the backing structure also includes each layer blooming piece, and routinely backlight framework is stacked the diaphragm group.
The utility model is embedded in light guide plate by cutting groove close to the exiting surface of incident side in light guide plate, by LED, and then
Reflector plate can above folding parcel light guide plate, using light guide plate for support, do not use backboard and glue frame, so as to simplified modular structure,
It is not only cost-effective, mitigate module weight, optics utilization rate can also be improved, increase brightness, optimization optics taste.
