Description
Technical field
The utility model relates to back light model setting technology fields, refer in particular to a kind of backlight mould for preventing dust foul from scratching light guide plate
Group.
Background technique
Existing backlight module, light guide plate upper surface are sticked reflectance coating, and reflectance coating both sides are easy into dust, foul, buffings,
In production or transportational process, dust, foul, buffings can enter light guide plate region and make on light guide plate to scratch light guide plate
At white point, to cause quality accident.
Therefore, the defect based on above-mentioned existing backlight module needs to improve existing backlight module.
Utility model content
Prevent dust foul from scratching light guide plate the purpose of this utility model is that providing one kind in view of the deficiencies of the prior art
Backlight module, which solves present in existing backlight module: light guide plate be easy to cause the defects of white point.
To achieve the above object, the utility model is achieved through the following technical solutions: one kind prevents dust foul from scraping
Hurt the backlight module of light guide plate, including glue frame, glue frame is rectangle, light guide plate is installed in glue frame, light guide plate and glue frame it is interior
Wall is in contact, and reflectance coating is posted in the upper surface of light guide plate, and adhesive tape is posted in the two sides of the lower surface of reflectance coating, two adhesive tape respectively with
Two sides of light guide plate fit closely.
The front end of the light guide plate is convex block, and the top surface of convex block is inclined surface, adhesive tape be pasted on the side of light guide plate with
And the side of inclined surface.
The utility model has the beneficial effects that: by the setting of adhesive tape, light guide plate sticks together with reflectance coating when assembling,
It solves the problems, such as that dust, foul, buffings enter light guide plate region and cause white point, white seal, improves product yield.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlargement diagram of the utility model.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Seeing Fig. 1 --- Fig. 2, a kind of backlight module for preventing dust foul from scratching light guide plate of the utility model includes: glue frame
1, light guide plate 2, reflectance coating 3, anti-dazzling screen 4, adhesive tape 5, inclined surface 6.
The utility model includes glue frame 1, and glue frame 1 is rectangle, and light guide plate 2, light guide plate 2 and glue are equipped in glue frame 1
The inner wall of frame 1 is in contact, and reflectance coating 3 is posted in the upper surface of light guide plate 2, and adhesive tape 5 is posted in the two sides of the lower surface of reflectance coating 3, and two
Adhesive tape 5 is fitted closely with two sides of light guide plate 2 respectively, by the setting of adhesive tape 5, light guide plate 2 and reflectance coating 3 when assembling
It sticks together, solves the problems, such as that dust, foul, buffings enter 2 region of light guide plate and cause white point, white seal, improve product yield.
As shown in Fig. 2, the front end of the light guide plate 2 of the utility model is convex block, the top surface of convex block is inclined surface 6, and adhesive tape 5 is viscous
It is affixed on the side of light guide plate 2 and the side of inclined surface 6.
The adhesive tape 5 of the utility model with a thickness of 0.04mm, width 0.4mm.
