Abstract
A light source device of backlight module of the utility model is provided with a light guide plate and a plurality of point light sources; each point light source receives light from a side edge of the light guide plate; each point light source is provided in the side edge of the light guide plate in a non-equal distance; the point light source is condenser in at least one outside adjacent to the light guide plate; the distance between each point light source decreases from the central position of the light guide plate to one of side edges of the light guide plate, such that the brightness in the central position of the backlight module can be promoted in order to improve the uniformity of light of the backlight module and reduce the utilization number of the point light source.
Description
Technical field
The utility model relates to a kind of light supply apparatus of backlight module, is intended to promote the briliancy of this backlight module central position, improving the uniformity of backlight module light, and can reduce the light supply apparatus of spot light usage quantity.
Background technology
Press, backlight module be LCD (Liquid Crystal Display, one of vital part LCD) is not because liquid crystal itself can be luminous voluntarily, so need behind liquid crystal panel, to add that external light source so that sufficient brightness and the light source that is evenly distributed to be provided, makes its normal show image; And the light source that backlight module often uses be CCFL with three-wavelength (Cold Cathode FluorescentLamp, CCFL) or light emitting diode (Light Emitting Diode, LED); Wherein as shown in Figures 1 and 2, it then is the backlight module framework that is applied to side-light type by light emitting diode, mainly by light emitting diode 11, LGP 12 and plural optics matrix 13 are formed, each light emitting diode 11 is with arranged evenly in the side 121 of LGP equally spacedly, each light emitting diode 11 is by side 121 light inlets, this LGP 12 receives the light that light emitting diode 11 sends, the light reflection that its bottom surface 122 will import, scattering, formation is along the homodisperse scattered beam of all directions, this exiting surface 123 should be derived LGP 12 by homodisperse light, the guiding display panels is to reach the effect that display panels shows.
And each light emitting diode is done equally spaced arrangement, and can influence the briliancy performance of whole backlight module, wherein its brightness value is low more the closer to both sides, so the uniformity of whole backlight module light is not good.
The utility model content
In view of this, the utility model is to promote the briliancy of this backlight module central position, improving the uniformity of backlight module light, and can reduce the light supply apparatus of spot light usage quantity.
For reaching above-mentioned purpose, the light supply apparatus of a kind of backlight module of the present utility model, it is provided with LGP and complex points light source, and each spot light is by the side light inlet of LGP; The side of this LGP is formed with first, second outside, and the spacing of each spot light by the LGP central position towards the outside wherein decrescence;
A kind of light supply apparatus of backlight module, this backlight module are provided with LGP and complex points light source, and each spot light is by the side light inlet of LGP; Each spot light is arranged at the side of this LGP with non-equidistance, and comparatively intensive near at least one outside of LGP.
The beneficial effects of the utility model are: backlight module is provided with LGP and complex points light source, each spot light is by the side light inlet of LGP, each spot light is arranged at the side of this LGP with non-equidistance, and it is comparatively intensive near at least one outside of LGP, that is between each spot light apart from wherein an outside is decrescence towards this LGP side by the LGP central position, can promote the briliancy of this backlight module central position, improving the uniformity of backlight module light, and can reduce the usage quantity of spot light.

The specific embodiment
The light supply apparatus of the utility model backlight module, as shown in Figures 3 and 4, this backlight module is provided with LGP 21, light supply apparatus (being provided with complex points light source 22) and plural blooming piece 23, and each spot light 22 is by side 211 light inlets of LGP 21, and this spot light 22 can be light emitting diode; Wherein, each spot light 22 is arranged at the side 211 of this LGP with non-equidistance, and it is comparatively intensive near LGP 21 at least one outsides, among the embodiment as shown in the figure, the side 211 of this LGP is formed with first, second outside 212,213, and between each spot light 22 apart from by LGP 21 central position towards the outside wherein (among the figure be example with first outside 212) decrescence, that is D2＜D1.
Moreover, between each spot light 22 apart from also can be towards first, second outside 212,213 decrescence, shown in another embodiment of Fig. 5 by LGP 21 central position; Among each embodiment of the present utility model, each spot light is arranged at the side of this LGP in the non-equidistance mode, can promote the briliancy of this backlight module central position, briliancy with the balance backlight module middle position and two outsides, improving the uniformity of backlight module light, and can reduce the usage quantity of spot light.
As mentioned above, the utility model provides side light type back light module another preferable feasible light supply apparatus, and the application of novel patent is offered in the whence in accordance with the law; Only, above implementation and graphic shown in, the utility model preferred embodiment person, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc. such as, identical person all should belong to of the present utility model founding within purpose and the claim.
