Abstract
The utility model provides a light guide plate having multi-ring-type screen dots. The light guide plate having the multi-ring-type screen dots includes a light guide plate substrate. The light guide plate having the multi-ring-type screen dots is characterized in that a plurality of screen dots composed of at least two notch ring structures, two bulge ring structures or two concave-convex ring structures are formed on the lower surface of the light guide plate substrate through hot press molding. The light guide plate having the multi-ring-type screen dots provided by the utility model has improved reflecting efficiency and reflecting intensity, and improves the luminance of a backlight.
Description
Technical field
The utility model relates to a kind of LGP.
Background technology
Along with development in science and technology, LCDs, LED lamp are also more and more universal.Usually its backlight is divided into side-light type back light and direct-light-type backlight according to light source position.Its product thickness of direct-light-type backlight is thick, and volume is big, seldom adopts at present.Its light source of side-light type back light is placed on LGP one side, can effectively reduce the volume of LCDs, LED lamp, and can obtain light source relatively uniformly, has been that the sector institute generally adopts at present.
Existing side-light type back light is made up of LGP, diffusion sheet, prismatic lens, light source, reflector plate, backlight usually.When backlight is worked; The light that light source sends is behind the side end face entering LGP of LGP; When total reflection back and forth between lower surface and two sides above that, the current site that is mapped to lower surface, reflected light is to all directions scattering and destroy total reflection condition; Make reflected light have an opportunity to transmit LGP, become output light from upper surface.To export light through diffusion sheet and spread and make light even, and diffusion light compiled, and improve and penetrate light intensity, improve brightness through prismatic lens.
At present, forming the site on its lower surface that LGP adopts realizes the reflection of light and destroys total reflection condition.Adopt usually the site is the reflection that concave point or salient point are realized light.Its reflective surface area of concave point one by one or salient point is limited, and incident light is more weak through the light intensity that this site reflects away.
Summary of the invention
The utility model technical matters to be solved provides a kind of LGP that can improve reflection strength.
For solving the problems of the technologies described above; The technical scheme of the utility model provides the LGP of a kind of polycycle site; It comprises the LGP substrate, it is characterized in that the lower surface of said LGP substrate hot-forming several at least by two hollow toroids, two bulge loop shapes or two sites that concavo-convex loop configuration is formed.The polycycle lattice point structure can improve the reflective surface area of site; Incident light is reflex time back and forth in upper and lower surfaces and side end face; Reflection projects upper surface through the site to have more rays, has improved the reflection efficiency and the reflection strength of LGP, makes back light source brightness higher.
Prism structure arranged in that the upper surface of said LGP is hot-forming.Go out prism structure in the hot pressing of LGP upper surface, make LGP and prism structure integrated, the assembling process and the separate prisms sheet manufacture process of separate prisms sheet and catheter plate exempted from letter, saved manufacturing cost.
Upper surface at said prism structure scribbles one deck diffusion layer.Diffusion layer, layers of prisms and LGP are combined as a whole, form the LGP that has prism structure and diffusion structure, it has greatly simplified the assembling procedure in the backlight assembling process, has also simplified the description that starting material are prepared, and has reduced production cost.
The LGP of the utility model, it forms prism structure and polycycle site through hot pressing respectively at the upper and lower surfaces of LGP simultaneously, and its manufacturing process is simple, has simplified manufacturing process, has reduced production cost.

Embodiment
To technique scheme, lift a preferred embodiment at present and combine graphic specifying.Wherein:
Embodiment 1
LGP 1, referring to Fig. 1, it comprises light guide base plate 10, light guide base plate adopts the plane light transmissive material to make.In hot-forming several sites of the lower surface of light guide base plate 10, each site is made up of a concave ring structure 20 and a bulge loop structure 21.Be positioned at the distolateral light source incident LGP of LGP 10 1, its incident light can pass through and project LGP 10 upper surfaces after concave ring structure 20 reflects respectively with bulge loop structure 21.When the upper surface of LGP 10 throwed, the light of its scattering carried out the upper surface that optically focused penetrates LGP 10 through prismatic lens again, improved the brightness that light transmits.Because concave ring structure 20 is a loop configuration with bulge loop structure 21; The reflective surface area of the site of its composition is bigger than the reflective surface area of simple concavity site or convex site; Can realize making the reflecting surface reflection of the incident light process ring-type of more crossing and project the LGP upper surface, improve reflection efficiency.
A site also can be formed by two concave ring structures in the site of the utility model, also can form a site by two bulge loop structures, also can be by combining to form a site greater than the concave ring structure more than 2, bulge loop structure or concavo-convex ring structure.
Embodiment 2
In order to simplify the technology of backlight assembling, on the basis of embodiment 1, the LGP 10 of the utility model referring to Fig. 2, has prism structure 30 through mould in that the upper surface of light guide base plate 10 is hot-forming downwards.Upper surface at prism structure 30 is provided with one deck diffusion layer 40.This diffusion layer 40 can pass through technological formings such as coating, ejaculation in the upper surface of the prism structure 30 of LGP 10 upper surfaces.Make incident light after the reflection of this LGP 10, the prism structure 30 on LGP 10 carries out optically focused, disperses atomizing through the diffusion layer that is coated on the prism structure again, makes acquisition output light light luminance good, and light is even.Because prism structure utilizes hot-pressing technique directly on light guide base plate, to form prism structure, it has practiced thrift the material cost of making layers of prisms; Diffusion layer is directly the integrated prism structure upper surface that is coated on the LGP, omitted the packaging technology of LGP, prismatic lens, diffusion sheet, reduced the assembling processing cost.
The process for making of the LGP of the utility model: through making mould up and down; Mold has prism structure; Bed die has the polycycle lattice point structure; Light guide base plate 10 is placed on up and down between the mould through mould heat pressure up and down, and once the upper and lower surfaces in light guide base plate 10 forms polycycle site and prism structure respectively.The manufacture craft that it has greatly reduced catheter plate has reduced the processing cost of LGP.
Claims (3)
1. polycycle site LGP, it comprises the LGP substrate, it is characterized in that the lower surface of said LGP substrate hot-forming several at least by two hollow toroids, two bulge loop shapes or two sites that concavo-convex loop configuration is formed.
2. polycycle according to claim 1 site LGP is characterized in that prism structure being arranged in that the upper surface of said LGP is hot-forming.
