Abstract
The utility model discloses a back light module group for a liquid crystal display. The back light module group comprises a plastic cement frame, an optical diaphragm, a light guide plate, lamp tube groups and a back plate, wherein the lamp tube groups are arranged at the two sides of the back plate, the light guide plate is arranged under the back plate and the lamp tube groups, the lamp tube groups and the back plate are parallelly arranged at the part of the back light module group near the outside, the side surface of the back plate is provided with a convex block, and a groove matched with the convex block is formed in the plastic cement frame. The convex block is arranged at the side surface of the back plate, the groove matched with the convex block is formed in the plastic cement frame, so the connection between the back plate and the plastic cement frame is more reliable, the lamp tube groups are arranged at the outermost part of the back light module group, the lamp tube groups can be directly dismounted in the disassembly process of the back light module group, and the goal of prolonging the service life of the back light module group is reached by utilizing the measure of replacing the lamp tube equipment.
Description
Technical field
The utility model relates to a kind of module backlight, particularly relates to a kind of backlight liquid crystal display module.
Background technology
LCD is a kind of flat-panel screens that is widely used most at present, because the liquid crystal itself in the display panels does not have the characteristics of luminescence, therefore, in order to reach display effect, need provide a planar light source device to display panels, module backlight for example, its function are to provide brightness fully and the planar light source that is evenly distributed to display panels.
The reliability that each element of existing module backlight connects is not high, in the process of LCD carrying and use, is easy to generate the slit between backboard and the plastic cement frame, has reduced the service life of LCD.In addition, the normally used fluorescent tube of module backlight is CCFL, and this causes module backlight to lose efficacy as the frangible product that split; The fluorescent tube briliancy in use can reduce along with the variation of fluorescent material, when be reduced to initial luminance 50% the time, also will cause module backlight to lose efficacy, change the life-span that fluorescent tube can prolong module backlight this moment.But in the module backlight of existing structure, in a single day fluorescent tube lost efficacy, and its unloading process is quite complicated, has wasted time and manpower, has reduced operating efficiency.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is, provides a kind of reliability high and be convenient to change the backlight liquid crystal display module of fluorescent tube equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of backlight liquid crystal display module, comprise plastic cement frame, blooming piece, LGP, light tube group and backboard, it is characterized in that: described light tube group is arranged on the both sides of described backboard, described LGP is located at the below of described backboard and light tube group, and described light tube group and described backboard are arranged side by side in described module backlight part outside; The side of described backboard is provided with projection, and described plastic cement frame is provided with the groove that matches with described projection.
Aforesaid a kind of backlight liquid crystal display module is characterized in that: the thickness of described projection equals the degree of depth of described groove.
Aforesaid a kind of backlight liquid crystal display module is characterized in that: described light tube group is fixed on the described plastic cement frame.
The utility model has the advantages that: the side at backboard is provided with projection, is provided with the groove that matches with projection at the plastic cement frame, makes backboard more reliable with being connected of plastic cement frame; Light tube group is arranged on the outermost of module backlight, makes module backlight in the disintegration process, can directly dismantle light tube group, change fluorescent tube equipment to utilize, reach the purpose that prolongs the module life-span backlight.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of backboard of the present utility model and light tube group.
The specific embodiment
For further disclosing the technical solution of the utility model, now be described with reference to the accompanying drawings embodiment of the present utility model: as shown in Figure 1 and Figure 2, a kind of backlight liquid crystal display module, comprise plastic cement frame 1, blooming piece 2, LGP 3, light tube group 4 and backboard 5, light tube group 4 is arranged on the both sides of backboard 5, and light tube group 4 is fixed on the plastic cement frame 1.LGP 3 is located at the below of described backboard 5 and light tube group 4, and light tube group 4 and backboard 5 are arranged side by side in module backlight part outside.The side of backboard 5 is provided with projection 6, and plastic cement frame 1 is provided with the groove 7 that matches with projection 6, and the thickness of projection 6 equals the degree of depth of groove 7.
More than by description of listed embodiment, basic design of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on the technical solution of the utility model of change all should belong to protection domain of the present utility model.
Claims (3)
1. backlight liquid crystal display module, comprise plastic cement frame, blooming piece, LGP, light tube group and backboard, it is characterized in that: described light tube group is arranged on the both sides of described backboard, described LGP is located at the below of described backboard and light tube group, and described light tube group and described backboard are arranged side by side in described module backlight part outside; The side of described backboard is provided with projection, and described plastic cement frame is provided with the groove that matches with described projection.
2. a kind of backlight liquid crystal display module according to claim 1, it is characterized in that: the thickness of described projection equals the degree of depth of described groove.
