Abstract
The utility model relates to an improved backlight of lamp-eye light beams. The improved backlight of the lamp-eye light beams comprises a light guide plate and an FPC. Light-emitting diode (LED) lamps are fixedly arranged on the FPC. The LED lamps are arranged behind the light guide plate. The light emitted by the LED lamps is emitted into the light guide plate from the rear lateral side of the light guide plate. A long-strip-shaped light-blocking part is arranged at the portion, between each LED lamp and the light guide plate, of the FPC. The light-blocking parts are arranged in front of the LED lamps. According to the improved backlight of the lamp-eye light beams, each light-blocking part is only and additionally arranged at the portion, between each LED lamp and the light guide plate, the high-brightness light generated by the LED lamps is diffused, the effects that brightness is even and faculae are avoided are achieved, and the improved backlight of the lamp-eye light beams has the advantages of being simple in structure, low in manufacturing cost and remarkable in effect.
Description
Technical field
The utility model relates to the backlight production technical field, particularly a kind of backlight of improveing lamp eye bundle.
Background technology
Existing backlight is general to adopt a plurality of LED lamps luminous, injects from the side in the LGP, and the diffusion mould by LGP and the back side thereof and reflectance coating make light penetrate from the front of LGP divergence of beam, reach effect backlight.
In the above-mentioned prior art, at close LED lamp place, because light is comparatively concentrated, brightness is bigger, can cause display screen bigger than normal in the side brightness near the LED lamp, has hot spot, has a strong impact on display effect sometimes, thereby reduces the experience of backlight display screen.
The utility model content
Main purpose of the present utility model is, at above-mentioned deficiency of the prior art, provides a kind of backlight of improveing lamp eye bundle, only adopts simple structure, just can make the light of backlight even, improves the display effect of display screen.
For achieving the above object, the utility model by the following technical solutions.
The utility model provides a kind of backlight of improveing lamp eye bundle, comprise LGP and FPC, be installed with the LED lamp at described FPC, described LED lamp is arranged at the rear of described LGP, and the light that described LED lamp sends is injected described LGP from the trailing flank of described LGP, FPC between described LED lamp and the LGP is provided with the light-blocking part of a strip, and described light-blocking part is arranged at the place ahead of described LED lamp.
Preferably, described light-blocking part is the white ink that is coated on the described FPC.
Preferably, described light-blocking part is the white light-diffusing film that is attached on the described FPC.
Than above-mentioned prior art, the utility model only FPC between LED lamp and LGP is set up light-blocking part, the LED lamp is produced the divergence of beam of high brightness, reach and make all even effects of avoiding hot spot of brightness, have simple in structure, low cost of manufacture and obvious results advantage.
Description of drawings
Fig. 1 is the structural representation of FPC among the utility model embodiment.
Fig. 2 is the structural representation of the backlight of improvement lamp eye bundle among the utility model embodiment.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
Describe the technical solution of the utility model in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present utility model intuitively.
Fig. 1 is the structural representation of FPC among the utility model embodiment; Fig. 2 is the structural representation of the backlight of improvement lamp eye bundle among the utility model embodiment.
Shown in seeing figures.1.and.2, present embodiment provides a kind of backlight of improveing lamp eye bundle, comprise LGP 1 and FPC 2, be installed with LED lamp 3 at described FPC 2, described LED lamp 3 is arranged at the rear of described LGP 1, and the light that described LED lamp 3 sends is injected described LGP 1 from the trailing flank of described LGP 1, and the FPC 2 between described LED lamp 3 and the LGP 1 is provided with the light-blocking part 4 of a strip, and described light-blocking part 4 is arranged at the place ahead of described LED lamp 3.
Particularly, above-mentioned light-blocking part 4 is a rectangular white ink, is coated on the FPC 2 corresponding with LED lamp 3.Or be attached at a white light-diffusing film on the FPC 2, the divergence of beam that utilizes this white ink or white light-diffusing film that LED lamp 3 is produced, make this part light can't pass FPC 2, perhaps evenly penetrate from the positive of LGP 1, thereby make from the LGP 1 positive light that penetrates even, hot spot can be do not occurred, good display can be reached.
In sum, the utility model only FPC between LED lamp and LGP is set up light-blocking part, and the LED lamp is produced the divergence of beam of high brightness, reaches to make all even effects of avoiding hot spot of brightness, has simple in structure, low cost of manufacture and obvious results advantage.
The above only is preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
