Abstract
The utility model relates to a backlight module for a liquid crystal display, which comprises a back plate and a light guide plate. The light guide plate is disposed in the concave space formed by the back plate. An elastic body is disposed between the back plate and the light guide plate. Through arranging the elastic body between the back plate and the light guide plate, the backlight module can prevent the light guide plate from deforming such as warping, etc., at the high temperature, and can absorb the impact energy at the normal temperature when the module is mechanically impacted, therefore, the mechanical performance of the whole module is improved, the phenomena such as various traces, ripples, light leakage, etc., due to the deformation of the light guide plate are avoided, and the display quality of images is improved.
Description
Technical field
The utility model relates to a kind of backlight module, especially a kind of backlight source of liquid crystal display apparatus module.
Background technology
Along with the live raising of grade of the development of lcd technology and people, the consumer is more and more higher to the quality requirements of liquid crystal display picture, and the illumination effect of backlight directly has influence on the picture quality of LCD.Owing to be subjected to the effect of extraneous and fluorescent tube heat, the dilatational strain of each parts of backlight source of liquid crystal display apparatus module is unavoidable, if handle the cooperation between the bad parts, will take place since display brightness inhomogeneous cause such as phenomenons such as various vestiges, ripple and light leaks.In numerous parts of backlight source of liquid crystal display apparatus module, the dilatational strain of light guide plate is the most serious, and backboard immediate constraint light guide plate, it is most important with cooperating of light guide plate therefore to handle backboard well.
Fig. 3 is the structural representation of prior art backlight source of liquid crystal display apparatus module, and as shown in Figure 3, the backlight source of liquid crystal display apparatus module of prior art all is to provide the space for the expansion of light guide plate 2 by leave and take certain interval between light guide plate 2 and backboard 1.Fig. 4 is the synoptic diagram behind the light guide plate expanded by heating in the prior art backlight source of liquid crystal display apparatus module, as shown in Figure 4, when light guide plate 2 expanded by heating, light guide plate 2 interacts with backboard buckling deformation takes place, cause entire liquid crystal display device backlight module torsional deformation, thereby cause phenomenons such as various vestiges, ripple and light leak, influence quality of display pictures.Find in actual the use, because the expansion coefficient of light guide plate is higher, especially for large-sized module, if the gap that is provided with is less, the excesssive gap that is provided with can cause the deformation of light guide plate warpage, if can cause the shift in position of light guide plate, reduce the mechanical property of backlight module, be difficult to the gap size between definite light guide plate and the backboard in therefore producing.
The utility model content
The purpose of this utility model provides a kind of backlight source of liquid crystal display apparatus module, effectively solves the problem that gap size is difficult to determine between prior art light guide plate and the backboard.
To achieve these goals, the utility model provides a kind of backlight source of liquid crystal display apparatus module, comprise backboard and light guide plate, described light guide plate places in the concave shaped space of described backboard formation, is provided with elastic body between the side of described backboard and the side of light guide plate.
Described elastic body is attached on the described backboard inner surface.
The outer surface of described light guide plate also is provided with reflectance coating, and described elastic body is attached on the described reflectance coating surface.
Described elastic body and described reflectance coating are for being wholely set.
On the technique scheme basis, described elastic body is the silica gel goods.
The utility model provides a kind of backlight source of liquid crystal display apparatus module; by between backboard and light guide plate, elastic body being set; not only can guarantee that when high temperature deformation such as warpage do not take place light guide plate; and can when being subjected to physical shock, module absorb impact energy at normal temperatures; protection module; improve the mechanical property of whole module, thereby avoided because the phenomenons such as various vestiges, ripple and light leak that light guide plate deformation causes have improved quality of display pictures.

Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 is the synoptic diagram of the utility model backlight source of liquid crystal display apparatus module first embodiment, as shown in Figure 1, the utility model backlight source of liquid crystal display apparatus module comprises backboard 1, light guide plate 2, reflectance coating 3 and elastic body 4, backboard 1 is a concave structure, light guide plate 2 places in the concave shaped space of backboard 1 formation, reflectance coating 3 is attached on the side surface of light guide plate 2 (being provided with except the light source side), and elastic body 4 is attached on the inner surface of the backboard 1 between backboard 1 and the reflectance coating 3.In backlight module work, be subjected to the time spent of doing of extraneous and fluorescent tube heat, light guide plate 2 expands owing to the material self-characteristic absorbs heat, replace on the elastic body 4 that is arranged on backboard 1 inside surface, elastic body 4 can shrink under the extruding of light guide plate 2, reserve bigger expansion space for light guide plate 2, so light guide plate 2 is difficult for taking place deformation such as warpage.In addition, at normal temperatures, when backlight module ran into physical shock, the setting of elastic body 4 closely cooperated light guide plate 2 and backboard 1, and most of energy that the elasticity of elastic body 4 can the absorption machine tool be impacted has improved the mechanical property of whole module.
Present embodiment backlight source of liquid crystal display apparatus module is by attaching elastic body in the backboard inboard, not only can guarantee that when high temperature deformation such as warpage do not take place light guide plate, and can when being subjected to physical shock, backlight module absorb impact energy at normal temperatures, improve the mechanical property of whole module, thereby avoided because the phenomenons such as various vestiges, ripple and light leak that light guide plate deformation causes have improved quality of display pictures.In addition, operation is convenient in the position that the utility model elastic body is attached on the backboard inboard, and cost is low.
Fig. 2 is the synoptic diagram of the utility model backlight source of liquid crystal display apparatus module second embodiment, and as shown in Figure 2, the structure of the present embodiment and first embodiment is basic identical, and difference is that elastic body 4 is attached on the outside surface of reflectance coating 3.In backlight module work, be subjected to the time spent of doing of the external world or fluorescent tube heat, light guide plate 2 expands owing to the material self-characteristic absorbs heat, replace on the backboard 1, owing to be provided with elastic body 4 at reflectance coating 3 outside surfaces, elastic body 4 can shrink under the extruding of light guide plate 2, reserve bigger expansion space for light guide plate 2, so light guide plate 2 is difficult for taking place deformation such as warpage.In addition, at normal temperatures, when backlight module ran into physical shock, the setting of elastic body 4 closely cooperated light guide plate 2 and backboard 1, and most of energy that the elasticity of elastic body 4 can the absorption machine tool be impacted has improved the mechanical property of whole module.
