It is same to be divided into side-light type and straight-down negative.
In existing backlight module, the position of internal optics diaphragm is not relatively fixed with other components, therefore often
Internal optics diaphragm and light guide plate can often occur or relatively moved between other optical diaphragms, after the two rubs for a long time
It is also easy to produce powder or cut, the uniformity that backlight module provides light source is influenced, to reduce the image quality of LCD screen.
Invention content
It, can be with regarding the issue above, the present invention provides a kind of ladder-like backlight module with limit assembly
Being fixed together only by the component of each layer in backlight module well makes it that opposite slide not occur.
To achieve the above object, the method that the present invention uses is：A kind of ladder-like backlight module with limit assembly, packet
Include light source, light guide plate, reflecting plate；The light source is bonded with the incidence surface of the light guide plate, is stacked gradually above the reflecting plate
There are light guide plate, diffusion sheet, a prismatic lens, and the area of every layer of component is bigger than its component area adjacent and above, it is as described anti-
It penetrates plate, light guide plate, diffusion sheet, prismatic lens and forms stepped construction, limit side wrapped plate, the limit are additionally provided on the reflecting plate
Side wrapped plate end portion is located in the straight slot that the reflecting plate opens up, and the limit side wrapped plate is also step structure and difference
It is tightly bonded with the light guide plate, diffusion sheet, the side wall of prismatic lens and upper surface, on the limit side wrapped plate and the reflecting plate
It is detachably connected by axis pin between the part and the reflecting plate of surface fitting.
As an improvement of the present invention, side wrapped plate is limited there are two being all provided on the surrounding side wall of the reflecting plate.
As an improvement of the present invention, the limit side wrapped plate that the reflecting plate is arranged on parallel opposite side two-by-two symmetrically divides
Cloth.
As an improvement of the present invention, it is connect with the light guide plate, diffusion sheet, prismatic lens on the limit side wrapped plate inner wall
Tactile position is equipped with antiskid rubber.
As an improvement of the present invention, the section at the top of the upper end of the bound edge limiting plate is triangular in shape.
Advantageous effect：
A kind of ladder-like backlight module with limit assembly of the present invention is arranged by multiple on backlight module side wall
The mutual cooperation of limit side wrapped plate wherein each plate is fixed, avoid relatively moving between them, carry
The uniformity of high backlight module light source, to promote the imaging effect of LCD screen.
Description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is the vertical view of the present invention；
Fig. 3 is enlarged diagrams of the Fig. 1 at A.
Each component is in figure：
1- light sources, 2- light guide plates, 3- reflecting plates, 4- diffusion sheets, 5- prismatic lens, 6- limit side wrapped plate, 7- straight slots, 8- skid-proof rubbers
Pad, 9- axis pins.
Specific implementation mode
With reference to embodiment and with reference to attached drawing, the invention will be further described, it should be understood that following specific implementation modes are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in width figure, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As an embodiment of the present invention, a kind of ladder-like backlight module with limit assembly in conjunction with described in attached drawing,
It is characterized in that：Including light source 1, light guide plate 2, reflecting plate 3；The light source 1 is bonded with the incidence surface of the light guide plate 2, described
The top of reflecting plate 3 is sequentially laminated with light guide plate 2, diffusion sheet 4, prismatic lens 5, and the area of every layer of component is adjacent and above than it
Component area is big, i.e., light guide plate above it is big, area of light guide plate is than stacking on it than stacking for the area of reflecting plate
Diffusion sheet is big, diffusion sheet area is bigger than the prismatic lens of stacking on it, and the surface area of component each so successively reduces shape
At stepped construction, limit side wrapped plate 6 is additionally provided on the reflecting plate 3,6 end portion of limit side wrapped plate is located at described anti-
Penetrate in the straight slot 7 that plate 3 opens up, and the limit side wrapped plate 6 also be step structure and respectively with the light guide plate 2, diffusion
Piece 4, the side wall of prismatic lens 5 and upper surface are tightly bonded, the portion that the limit side wrapped plate 6 is bonded with 3 upper surface of the reflecting plate
Divide and is detachably connected by axis pin between the reflecting plate 3.Each side-walls of backlight module limit bound edge there are two being all provided with
Plate 6, and the limit side wrapped plate 6 in opposing sidewalls is symmetrically distributed, stepped limit side wrapped plate 6 facing each other in this way
Limitation locking is carried out to each plate type part of backlight module, avoids its generation relative motion in use.In addition it is limiting
