Abstract
The utility model discloses a kind of novel backlight structure.Wherein：The side of light guide plate is provided with glue frame；Diffusion sheet is provided between glue frame and light guide plate；A groove is formed between glue frame and light guide plate；A part for described diffusion sheet reaches the inside below glue frame, i.e. a part for diffusion sheet is reached in groove.As middle large scale backlight develops, quality requirements increasingly increase, backlight Integral luminous effect requirements more and more higher, and client also increases to the requirement of backlight LED sides illumination effect, and in past design, the LGP processing rising spaces are less and less.In traditional design, membrane material is general all concordant with glue frame, and diaphragm shaded effect is poor, the easy luminance nonuniformity of socket effect.The utility model has the advantage of：It is simple in construction, sheltered from by the light part that a part for diffusion sheet is put in diffusion inside glue frame by glue frame, reached using the shaded effect of glue frame and reduce the uneven purpose of side illumination effect.
Description
Technical field
A kind of back light module unit structure is the utility model is related to, especially a kind of novel backlight structure.
Background technology
As middle large scale backlight develops, quality requirements increasingly increase, backlight Integral luminous effect requirements more and more higher, visitor
Family also increases to the requirement of backlight LED sides illumination effect, and in past design, LGP has handled the rising space increasingly
It is small.In traditional design, membrane material is general all concordant with glue frame, and diaphragm shaded effect is poor, the easy luminance nonuniformity of socket effect.
The content of the invention
Task to be solved in the utility model is to provide a kind of novel backlight structure so that reaches and reduces side illumination effect not
Equal purpose.
In order to solve the above problems, the utility model is achieved through the following technical solutions：
A kind of novel backlight structure, including：Glue frame, diffusion sheet, light guide plate, groove；Wherein：The side of light guide plate is provided with
Glue frame；Diffusion sheet is provided between glue frame and light guide plate；A groove is formed between glue frame and light guide plate；Described diffusion sheet
A part reaches the inside below glue frame, i.e. a part for diffusion sheet is reached in groove.
A kind of novel backlight structure, raised line is provided with its further groove.
The utility model has the advantage of：It is simple in construction, expanded by the way that a part for diffusion sheet is put in inside glue frame
A scattered light part is sheltered from by glue frame, is reached using the shaded effect of glue frame and reduces the uneven purpose of side illumination effect.
Brief description of the drawings
Fig. 1 is the positional structure schematic diagram of groove of the present utility model.
Fig. 2 is the position view of diffusion sheet of the present utility model.
Reference：Glue frame 1, diffusion sheet 2, light guide plate 3, groove 4, raised line 5.
Embodiment
Embodiment 1, a kind of novel backlight structure, including：Glue frame 1, diffusion sheet 2, light guide plate 3, groove 4；Wherein：Light guide plate
3 side is provided with glue frame 1；Diffusion sheet 2 is provided between glue frame 1 and light guide plate 3；One is formed between glue frame 1 and light guide plate 3
Groove 4；A part for described diffusion sheet 2 reaches the inside of the lower section of glue frame 1, i.e. a part for diffusion sheet 2 is reached in groove 4.
Embodiment 2, a kind of novel backlight structure, wherein：Raised line 5 is provided with groove 4.Remaining is the same as embodiment 1.
Operation principle：
The utility model large-sized backing structure in being mainly used in, the film of the generally conventional placement from the bottom up of light guide plate 3
Piece has diffusion sheet 2, brightening piece, anti-dazzling screen；Diffusion sheet 2 and other related membrane layers edge that gathers into folds align, then against glue
Frame 1, but still with the presence of gap between diaphragm and glue frame 1, the phenomenon for additionally having diaphragm edge out-of-flatness occurs, so
The backlight source module encapsulated, the illumination effect of brightness disproportionation, the small size of conventional can be being showed at glue frame 1
Backlight source module in secret note placed typically on diffusion sheet 2 reach and reduce the uneven phenomenon of this side illumination effect；This practicality
It is new by the way that one end of diffusion sheet 2 is put in glue frame 1, by the way that secret note is replaced with into glue frame 1 so that glue frame 1 plays and small chi
The same effect of secret note in very little backlight, so reduce gap light leak and diaphragm edge it is irregular caused by side illumination effect
Uneven phenomenon, the elasticity of raised line 5 of setting is larger, the pressure increase that diffusion sheet can be caused to be subject to, is easy to fix.
