Abstract
The utility model discloses a backlight source with diffusion points, which comprises a rubber frame, a light source placed inside the rubber frame, a FPC circuit panel, a light guide plate, a diffusion film, a brightness enhancement film and a shading film as well as a reflection film laid on the back of the rubber frame, wherein a plurality of fine and compact atomization points in a certain small area are arranged and distributed on the light guide plate at a light source lighting mouth. In the utility model, an original major structure of a backlight module needs not to be changed basically, no complicated process needs to be added, light rays at the LED lighting mouth are diffused and scattering is realized, thus spot size is effectively decreased and relatively good visual effect is reached.
Description
Technical field
The utility model belongs to backlight source module field, especially relates to a kind of backlight of the band diffusion point that can effectively eliminate LED light outlets hot spot.
Background technology
At present, along with the development in epoch, people show and require the motive force of development and direction more and more higher, highlighted, ultra-thin, that large scale becomes the continuous lifting of industry technology backlight mobile phone.
Mobile phone display backlight module is side incident type structure now, and light source is the side that is positioned at exiting surface.LED is similar to spot light, very high near the brightness of LED light-emitting area part, as bad in backlight module optical treatment, before LED light-emitting area, can produce hot spot.Because thin-type LED brightness at present cannot meet highlighted demand, the LED of 0.6T or main flow, but the thickness of critical piece LGP backlight is but more and more thinner, conventionally in 0.4T left and right, so more increased the difficulty of optical treatment, this is also one of factory backlight of current each family technological difficulties.
LGP is to be whole luminous medium of backlight module by LED point luminescent conversion, and LED light by site, diffuse reflection occurs after injecting in LGP, upsets the original round of light, and light is vertically penetrated from exiting surface as far as possible.LGP is as most important optics in backlight module, the quality of its processing is directly affected and wants backlight group of final illumination effect, and the lattice point structure most important optical texture that is LGP, conventional site arrangement method is difficult to meet the vision requirement that client is more and more higher, especially thin light guide panel is used the backing structure of thick LED, and LED light outlets hot spot is difficult to eliminate.
Utility model content
The purpose of this utility model is to provide a kind of backlight with diffusion point, effectively eliminates LED light outlets hot spot, solves the defect that prior art exists.
For achieving the above object, the technical solution adopted in the utility model is:
With a backlight for diffusion point, comprise glue frame, be placed in light source, FPC wiring board, LGP, diffusion barrier, bright enhancement film, photomask in glue frame, and be laid in the reflectance coating at the glue frame back side; It is characterized in that: described LGP is positioned at light source luminescent mouth position and is placed with thin and close some atomization points of certain zonule.
Further, described atomization point is for equidistantly arranging.
Further, described light source is LED light source.
Further, described diffusion barrier is one deck, and described bright enhancement film is two-layer, and two-layer bright enhancement film is all laid on diffusion barrier.Described diffusion barrier can be also two-layer, is respectively diffusion barrier and lower diffusion barrier, and described bright enhancement film is two-layer, and two-layer bright enhancement film is laid between lower diffusion barrier and upper diffusion barrier.
The utility model, by be positioned at arrange thin and close some atomization points of certain zonule of light source luminescent mouth position at LGP, can effectively be eliminated LED light outlets hot spot.The utility model does not need to change the agent structure of original backlight module substantially, does not need to increase complicated operation, and the light of LED light outlets is spread, and plays the effect of scattering, thereby effectively reduces spot size, reaches good visual effect.Effectively solve a difficult problem that always perplexs industry in prior art, there is good prospects for commercial application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of atomization point part.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 and 2, the backlight of the band diffusion point described in the present embodiment, comprise glue frame 1, be placed in LED light source 3, FPC wiring board 4, LGP 2, diffusion barrier 5, upper bright enhancement film 62 and lower bright enhancement film 61, photomask 7 in glue frame, and be laid in the reflectance coating 8 at the glue frame back side and reflect gum 9, reflectance coating 8 is fixed by double faced adhesive tape 91 and the glue frame back side; FPC wiring board 4 is pasted fixing by PFC double faced adhesive tape 41; LGP is positioned at light source luminescent mouth position and is placed with thin and close some atomization points 21 of certain zonule, and atomization point is for equidistantly evenly arranging.Described diffusion barrier is one deck, and described bright enhancement film is two-layer, and two-layer bright enhancement film is all laid on diffusion barrier.Certainly, described diffusion barrier can be also two-layer, is respectively diffusion barrier and lower diffusion barrier, and described bright enhancement film is two-layer, and two-layer bright enhancement film is laid between lower diffusion barrier and upper diffusion barrier; Can realize equally goal of the invention of the present utility model.
The design of arranging in site: use site to arrange after design software arranges conventional site to have designed, corresponding socket Position Design atomization point arranges in design drawing.Atomization point is arranged as equidistant, dense arrangement.
The processing of site: laser processing can realize multiple processing conditions and process on a die simultaneously, conventional site is set to respectively to different processing conditions from atomization point, rear processing before processing.Because there is certain absorption effects site own, for not affecting backlight luminescence brightness, atomization point need be little and shallow, and therefore laser energy is adjusted and must be significantly smaller than conventional some energy.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
