Abstract
The utility model discloses a novel backlight module shading structure which comprises black-and-white shading glue and a polyethylene terephthalate (PET) film which is covered on the black-and-white shading glue. The PET film comprises a body and a handle, wherein the body is covered on the black-and-white shading glue, the handle is stretched outward from the middle of one side of the body, the handle of the PET film is exposed out of the black-and-white shading glue, and the PET film covered on the black-and-white shading glue can prevent the black-and-white shading glue from being stained with dust. In addition, the handle of the PET film is exposed out of the black-and-white shading glue, and therefore after a backlight source and a liquid crystal display (LCD) are combined to form an LCD device, the handle of the PET film can be pulled through one hand to be removed, and the PET film is convenient to remove.
Description
Technical field
The utility model relates to the backlight field of liquid crystal display, particularly relates to the light-shielding structure of backlight module.
Background technology
Liquid crystal display (LCD) is widely used in the Display Technique field, the demonstration of liquid crystal normally forms the function that the liquid crystal of electric field driven between electro-conductive glass realized demonstration by two electro-conductive glass, but liquid crystal itself can not be luminous, therefore need to really realize Presentation Function by external light source, the backlight of main flow has LED-backlit source and TTF backlight at present.Backlight and LCD stick together by the black and white shading glue, the black and white shading glue is to paste LCD and backlight in this one of effect, and another one is shading, and the black and white shading glue is stained with dust easily, the black and white shading glue is stained with after the dust, can make a big impact to the display effect of LCD.
The utility model content
The purpose of this utility model is to overcome the deficiency of present technology, and a kind of novel backlight module light-shielding structure is provided, and it can avoid the black and white shading glue to be stained with the problem of dust.
For achieving the above object, the technical scheme that adopts of the utility model is:
A kind of novel backlight module light-shielding structure, comprise a black and white shading glue, cover the PET film on the black and white shading glue, described PET film comprises that one covers the body on the black and white shading glue, the handle that also comprises past extension in the middle of body one side, and the handle of described PET film is exposed to outside the black and white shading glue.
The handle width of described PET film is less than body.
There is the chamfering of carrying out at the position that described handle both sides are connected with body.
Described chamfer radius is not less than 1.0MM.
The beneficial effects of the utility model are: because covered one deck PET film at the black and white shading glue, thereby can prevent that the black and white shading glue is stained with dust; And the handle of PET film is exposed to outside the black and white shading glue, thereby after backlight and LCD are combined into liquid crystal display, can haul on the other hand the handle of PET film, thereby the PET film is removed, and that is to say removing easily of PET film; In addition, because the position that the both sides of PET film handle are connected with body is provided with chamfering, rather than the right angle, so, can avoid when removing the PET film, handle being torn down from body, thus the problem of avoiding the PET membrane body not to be removed.
Description of drawings
Fig. 1 is the schematic diagram of the utility model backlight module light-shielding structure.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model backlight source module light-shielding structure comprises a black and white shading glue 1, covers the PET film 2 on the black and white shading glue 1.Described PET film 2 comprises that one covers the body 21 on the black and white shading glue 1, also comprise the handle 22 of past extension in the middle of body 21 1 sides, and the handle 22 of described PET film 2 is exposed to outside the black and white shading glue 1.
In the present embodiment, preferably, handle 22 width of described PET film 2 are less than body 21, and there is the chamfering of carrying out at the position 23 that handle 22 both sides are connected with body 21, and chamfer radius namely is not less than 1.0MM more than 1.0MM.
In sum, because covered one deck PET film 2 at black and white shading glue 1, thereby can prevent that black and white shading glue 1 is stained with dust; And the handle 22 of PET film 2 is exposed to outside the black and white shading glue 1, thereby after backlight and LCD are combined into liquid crystal display, can haul on the other hand the handle 22 of PET film 2, thereby PET film 2 is removed, and that is to say removing easily of PET film 2; In addition, because the position 23 that the both sides of PET film 2 handles 22 are connected with body 21 is provided with chamfering, rather than the right angle, so, can avoid when removing PET film 2, handle 22 being torn down from body 21, thus the problem of avoiding PET film 2 bodies 21 not to be removed.
