Abstract
The utility model discloses a kind of back light module unit structure, it include: backlight module ontology, the backlight module ontology is equipped with optical diaphragm, shading glue and two adhesive tape, the shading glue is in Back Word type and is attached on the optical diaphragm, the shading glue includes the hollow-out parts at middle part and the attaching portion of surrounding, four interior angles of the hollow-out parts are fillet, the adhesive tape is attached at one side of the attaching portion towards the optical diaphragm, and be located on the region of two rounded edges of backlight, the one side of the adhesive tape towards the optical diaphragm is white.The phenomenon that the utility model structure is simple easily operated and cost is relatively low, can avoid the occurrence of dark space, makes the brightness uniformity for obtaining light, improving optical effect.
Description
Technical field
The utility model relates to display module technical field more particularly to a kind of back light module unit structures.
Background technique
In backlight module industry, the bright dark and uniformity of light that backlight module goes out light is very important index, and carries on the back
The effect of shading glue in optical mode group is that light region and non-outgoing area are marked off in display module.Common shading glue has black
White double-sided adhesive and two kinds of black double-sided adhesive, and black and white double faced adhesive tape is easy to make display module in display in the output optical zone output optical zone Yu Hefei
The edge in domain forms bright line, therefore black and white double faced adhesive tape is gradually being eliminated.But with the development of liquid crystal display, part is shown
Four right angles development of viewing area is fillet in screen, this makes backlight module go out light at the fillet of backlight side two
There is the problems such as dark space, light guide is uneven because of the scattering blind area of light in region and non-outgoing area intersection, influence using
Effect.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of back light module unit structure.
The technical solution of the utility model is as follows: the utility model provides a kind of back light module unit structure, comprising: backlight module
Ontology, the backlight module ontology are equipped with optical diaphragm, shading glue and two adhesive tape, and the shading glue is in Back Word type and attaches
In on the optical diaphragm, the shading glue includes the hollow-out parts at middle part and the attaching portion of surrounding, in four of the hollow-out parts
Angle is fillet, and the adhesive tape is attached at one side of the attaching portion towards the optical diaphragm, and is located at close to backlight
Two rounded edges region on, the adhesive tape towards the optical diaphragm one side be white.
Preferably, the adhesive tape is arc-shaped, and the adhesive tape edge shape is consistent with the rounded edges shape, the glue
Item correspondence is attached at the rounded edges.
Further, the thickness of the adhesive tape is less than or equal to 0.05 millimeter.
Further, the adhesive tape is located in attaching portion region.
Further, the adhesive tape is two-sided white adhesive tape or black and white double faced adhesive tape item.
Further, the backlight is LED light.
Using the above scheme, the utility model structure is simple easily operated and cost is relatively low, can avoid the occurrence of dark space
Phenomenon makes the brightness uniformity for obtaining light, improving optical effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of back light module unit structure, comprising: backlight module ontology, the backlight mould
Group ontology is equipped with optical diaphragm 3, shading glue 1 and two adhesive tape 2, and the shading glue 1 is in Back Word type and is attached at the optics
On diaphragm 3, the shading glue 1 includes the hollow-out parts 12 at middle part and the attaching portion 11 of surrounding, four interior angles of the hollow-out parts 12
For fillet, the adhesive tape 2 is attached at the attaching portion 11 towards the one side of the optical diaphragm 3, and is located at close to backlight
On the region of two rounded edges in source 4, the one side of the adhesive tape 2 towards the optical diaphragm 3 is white, and the adhesive tape 2 can
Think two-sided white adhesive tape or black and white double faced adhesive tape item.The thickness of the adhesive tape 2 is less than or equal to 0.05 millimeter.The adhesive tape 2
In in 11 region of attaching portion.The backlight 4 is LED light.By the reflection of the adhesive tape 2, the backlight mould can be made
The phenomenon that organizing uniform in light emission, avoiding the occurrence of dark space.
It is worth one, the adhesive tape is arc-shaped or rectangle or other irregular bodies, preferably it is arc-shaped, and
The adhesive tape edge shape is consistent with the rounded edges shape, and the adhesive tape correspondence is attached at the rounded edges.It can obtain
Optimal optical effect is obtained, so that backlight module emitting brightness is uniform.
In conclusion the utility model structure is simple easily operated and cost is relatively low, the phenomenon that dark space can be avoided the occurrence of,
Make the brightness uniformity for obtaining light, improving optical effect.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
