Description of the drawings
Fig. 1 is the cross-sectional view of the backlight module of the utility model embodiment.
Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, many technical details are proposed in order to make reader more fully understand the utility model.But even if without this
A little technical details and various changes and modifications based on the following respective embodiments, can also realize each claim of the utility model
Technical solution claimed.
The embodiment of the utility model is related to a kind of backlight module 100, as shown in Figure 1, including：Panel 1 is arranged in face
The light guide plate 2 of 1 incident side of plate, is successively set on reflector plate 3 and backboard 4 of the light guide plate 2 far from 1 side of panel, and setting is being reflected
Buffer layer 5 between piece 3 and backboard 4, buffer layer 5 are mutually abutted with reflector plate 3 and backboard 4.
The utility model embodiment in terms of existing technologies, is buffered by being arranged between reflector plate 3 and backboard 4
Layer 5, to buffer hard contact and the extruding between backboard 4 and reflector plate 3, avoids 4 direct hard contact of reflector plate 3 and backboard
Reflector plate deforms caused by squeezing afterwards so that therefore display screen hickie problem will not occur, improve display effect.In addition, the back of the body
There are when foreign matter between plate 4 and reflector plate 3, buffer layer can cause to squeeze to avoid foreign matter to reflector plate, play cushioning effect, from
And it can be to avoid the display effect of foreign materials away display screen.
Preferably, in present embodiment, buffer layer 5 is platy structure.Since buffer layer 5 is arranged in reflector plate 3 and backboard 4
Between, and abutted with reflector plate 3 and backboard 4, its surfacing and upper and lower surface can be made by setting buffer layer 5 to platy structure
It is parallel, it avoids causing reflector plate 3 and the inclination of 4 position of backboard etc. because of the setting of buffer layer 5 so that reflector plate 3, buffer layer 5, the back of the body
Plate 4 can form a stable laminated construction of comparison.
Specifically, backboard 4 include with 3 first part 41 disposed in parallel of reflector plate and from first part 41 away from
The interconnecting piece 43 of the direction bending of reflector plate 3 and extend from the interconnecting piece along the direction parallel with the first part
Second part 42, first part 41 are arranged in parallel with buffer layer 5 and mutually abut.First part 41 is supported buffer layer 5,
Buffer layer 5 is steadily clamped between backboard 4 and reflector plate 3.The bending deformation of interconnecting piece 43 can be to first part
41 and second part 42 play connection function, so that first part 41 is connect with second part 42 by interconnecting piece 43, and make
First part 41 and second part 42 are not in the same plane.Second part 42 supports the other component abutted with it, to make
The component supports reflector plate 3 jointly with backboard 4.
Further, backlight module 100 further includes VCM (vinyl chloride monomer, vinyl chloride) plate 6, VCM plates
The one end at 61 center of close panel bears against on second part 42 and is arranged in parallel with buffer layer 5 and mutually abuts.VCM plates 6
Buffer layer 5 is supported jointly with the first part 41 of backboard 4 so that buffer layer 5 more stable can be clamped in reflector plate 3 and backboard 4
Between.
Specifically, the flush on the surface of 6 face buffer layer 5 of VCM plates and 41 face buffer layer 5 of first part.In this way,
The steady installation for being conducive to buffer layer 5 further facilitates the compactedness of structure between the installation and component of backlight module 100.
It should be noted that the material of buffer layer 5 can be elastic material.Since elastic material can be made with compressive deformation
It is unlikely to damage the backboard 4 abutted with it and reflector plate 3 because of hard contact and extruding due to for buffer layer.In addition, reflector plate 3 and the back of the body
There are when foreign matter between plate 4, elastic material can also avoid foreign matter from causing to squeeze to reflector plate, play cushioning effect, so as to
To avoid the display effect of foreign materials away display screen.Preferably, the elastic material can be sponge.
Specifically, backlight module 100 further includes：Plastic parts 7 and framework 8 in the edge of backboard 4, plastic parts 7 are set
Against the edge of panel 1, the edge of backboard 4, the edge of panel 1 and plastic parts 7 are coated on interior by framework 8.By using change
The small plastic parts 7 of shape amount supports panel 1 against the edge of panel 1, and panel 1 is enable firmly to be supported, and will not make
With position movement occurs because of the deformation of plastic parts 7 in the process, to improve 100 integrally-built stability of backlight module.Together
When, framework 8 plays backboard 4, panel 1 and plastic parts 7 in being coated on the edge of backboard 4, the edge of panel 1 and plastic parts 7
To protective effect.
Further, backlight module 100 further includes flexible PCB 9, and preset clearance 90, soft between framework 8 and plastic parts 7
Property circuit board 9 be arranged in gap 90.It is arranged in flexible PCB 9 can be housed in by the framework 8 in 9 outside of flexible PCB
And play a protective role, avoid flexible PCB 9 from being squeezed damage.
It should be noted that in present embodiment, framework 8 can be aluminium casting die.Aluminium casting die ductility is good, is readily designed to
Type, and aluminium casting die is metal material, and the heat conductivility of metal material is good, thus used in present embodiment aluminium casting die as
Framework 8 is also convenient to radiate to light source (not shown).Preferably, aluminium casting die can be Al squeezing material, since Al squeezing material can
To ensure certain structural strength, be unlikely to deform, so as to in being coated on the edge of backboard 4, the edge of panel 1 and
Plastic parts 7 plays preferable protective effect.In addition, in other embodiments, framework 8 or plastic cement material, due to
Plastic cement material deflection is small, and stationarity is good, will not because external compression deform and influence coated by framework backboard 4 edge,
The edge of panel 1 and the structure of plastic parts 7, can also play a very good protection.
In addition, backlight module 100 can also include being arranged in hard circuit board 11 of the backboard 4 far from 2 side of light guide plate, firmly
Property circuit board 11 is connect by flexible PCB 9 with panel 1.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
And range.
