Abstract
The utility model relates to a backlight module allowing light incidence at a side end. The backlight module comprises a light guide plate and at least one light source, wherein the light source is arranged at the side end of the light guide plate; and the bottom face of the light guide plate is provided with a plurality of lattice points which are provided with a plurality of characteristic blocks. The characteristic blocks are of a polygon structure. The lattice points are uniformly distributed on the bottom face of the light guide plate. The characteristic blocks are arranged on the lattice points close to the head and tail of the light source as well as the lattice points located in the groove of the light guide plate. According to the utility model, light rays produced by the light source are emergent by transmitting through the light guide plate and are optically refracted and reflected through the characteristic blocks added based on the distribution of the lattice points of the light guide plate, so that the brightness of dark zones is increased, and the technical problem that the light guide plate is provided with dark zones at corners close the head and the tail of the light source or the groove of the light guide plate is solved.
Description
Technical field
The utility model relates to a kind of module backlight, particularly a kind of module backlight of side light inlet.
Background technology
LCD (LCD) is widely used in computer, communication apparatus and other various displays, and general LCD mainly is made up of liquid crystal panel and module backlight, and wherein, liquid crystal panel itself is not luminous, and the light source of panel is provided by module backlight.
Please refer to Fig. 1, existing module backlight comprises light source 2 and LGP 1, and this light source 1 is with respect to the incidence surface setting of LGP 2, and this LGP 1 guiding converts line source or spot light to the area source outgoing from the transmission direction of the light of light source 2.A plurality of sites that distribute, the bottom surface of this LGP 1 are in order to be scattered in the light of LGP 1 internal transmission, to improve the uniformity of LGP 1 emergent ray.But, please refer to Fig. 1, LGP 1 has dark corner near light source 2 head and the tail places or LGP 1 groove, and is specific as follows:
1, because of the actual luminous size in lamp source less than LGP light inlet size, LGP incident side corner can produce the dark space;
2, because of the light source specific refraction is different, can produce the dark space at the LGP groove;
The mode of the size of adjustment site or density made the zone of dark space increase brightness when prior art often adopted network point distribution, still, adopted this kind mode often to cause Luminance Distribution inhomogeneous.
The utility model content
The purpose of the utility model is to provide a kind of module backlight of side light inlet, is locating from beginning to end near light source or the LGP groove has the technical problem of dark corner to solve in the prior art LGP.
In order to address the above problem, the utility model provides a kind of module backlight of side light inlet, comprises a LGP and at least one lamp source, and said lamp source is arranged at the side of LGP; The bottom surface of said LGP is provided with some sites, and the certain characteristics piece is set on the said site.
Preferably, said characteristic block is a polygonized structure.
Preferably, said site is evenly distributed on the bottom surface of LGP.
Preferably, said characteristic block is arranged on the site of locating from beginning to end near the lamp source.
Preferably, said characteristic block is set in place on the site of LGP groove.
Compared with prior art, there is following technique effect in the utility model:
The module backlight of a kind of side light inlet of the utility model, the light that the lamp source produces sees through LGP and penetrates, and the characteristic block that increases when distributing through light guide plate mesh point carries out optical refraction and radiation, to promote the brightness of dark space.
Description of drawings
Fig. 1 is the structural representation that LGP produces the dark space in the prior art;
Fig. 2 is arranged on the structural representation on the site of locating from beginning to end near the lamp source for the utility model characteristic block;
Fig. 3 is arranged on the structural representation on the LGP groove site for the utility model characteristic block.
The specific embodiment
The utility model provides a kind of module backlight of side light inlet, comprises a LGP and at least one lamp source, and the lamp source is arranged at the side of LGP; The bottom surface of LGP is provided with some sites, and the certain characteristics piece is set on the site.In the utility model, the light that the lamp source produces sees through LGP and penetrates, and the characteristic block that increases when distributing through light guide plate mesh point carries out optical refraction and radiation, to promote the brightness of dark space.Below in conjunction with accompanying drawing, lift a specific embodiment and describe in detail.
A kind of module backlight of side light inlet comprises a LGP and at least one lamp source, and the lamp source is arranged at the side of LGP, and the bottom surface of LGP is provided with some sites.The certain characteristics piece is set on the site, and characteristic block is a polygonized structure.The utility model does not limit the structure of characteristic block, and the user can come specifically to be provided with shape, size and the particular location of characteristic block according to the structure of network point distribution size and bottom surface of light guide plate.
In the present embodiment, the site is the bottom surface that is evenly distributed on LGP.
Please refer to Fig. 2, when site 30 distributes, at the head and the tail place of LGP 10 near lamp source 20, be provided with characteristic block 1, present embodiment is not limit the number of characteristic block 1.In the present embodiment, this characteristic block 1 is the triangular form structure, and the length of this characteristic block 1 is 10-30 millimeters, and width is 1-5 millimeters, and in the utility model, the shape of characteristic block 1 and size are not limited thereto here.LGP 10 distributes site 30 through technologies such as printing/ejaculation and is made on the LGP 10, and characteristic block 1 is arranged on the site of locating from beginning to end near lamp source 20 30, makes LGP 10 20 improve dark area effect when luminous in the lamp source.
Please refer to Fig. 3, when site 30 distributed, characteristic block 2 50 was arranged on the groove of LGP 10.In the present embodiment, the number of characteristic block two is relevant with the number of the groove of LGP 10, and present embodiment is not done concrete restriction to the number of characteristic block 2 50, can decide according to actual conditions.In the present embodiment, this characteristic block 2 50 is a quadrilateral structure, and the length of this characteristic block 2 50 is 10-30 millimeters, and width is 2-6 millimeters, and in the utility model, the shape of characteristic block 2 50 and size are not limited thereto here.LGP 10 is made in site 30 distributions on the LGP 10 through technologies such as printing/ejaculations, and characteristic block 2 50 is set in place on the site 30 of LGP 10 grooves, makes LGP 10 20 improve dark area effect when luminous in the lamp source.
More than a disclosed specific embodiment that is merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
