Abstract
The utility model relates to an ultrathin light guide plate light guide structure of a backlight source, which consists of a circuit board, a reflecting membrane and a light guide plate, wherein the reflecting membrane, the light guide plate, a diffusion membrane, a lower brightening membrane, an upper brightening membrane and an anti-dazzling screen are arranged on the right side of a bracket from bottom to top; the light guide plate is designed into a stepped structure; an LED is arranged on the right side of the light guide plate; a circuit board is arranged below the LED; and the height of the light guide plate at light incidence position is equal to that of the opening of the illuminating part of the LED. The ultrathin light guide plate light guide structure has a simple structure, is easy to carry out, and is suitable for batch production. The flat light guide plate is designed into the stepped light guide plate, so as to facilitate guiding all the light source emitted by the LED into the light guide plate, and solves the problem of the existing structure that the light source emitted by the LED can't be fully guided into the light guide plate.
Description
Technical field
The utility model relates to a kind of LED-backlit source ultra-thin light guide board light guide structure, is applicable to LED-backlit source industry.
Background technology
Present known structure, LGP is an one flat plate, when light guide plate is less than LED light outlets thickness; Partly light source can not import LGP and lose, and in order to reach the brightness of backlight, can only increase the quantity of LED; Also just increase cost accordingly, increased business burden.
Summary of the invention
The purpose of the utility model is said so will provide a kind of backlight ultra-thin light guide board light guide structure, and its difficulty overcomes the existing existing problem of above product.The purpose of the utility model is to realize like this; Backlight ultra-thin light guide board light guide structure; Comprise that wiring board, reflectance coating, LGP form, it is characterized in that: support the right be disposed with from bottom to up reflectance coating, LGP, diffusion barrier, down brightness enhancement film, on increase film, anti-dazzling screen; Described LGP is designed to ladder-type structure, and the right of LGP is provided with LED, and the below of LED is provided with wiring board; The LGP height of light inlet equates with LED illuminating part open height.The utility model is simple in structure, and is easy to implement, is fit to produce in batches.Flat LGP is designed to the stepped appearance LGP, all imports LGP, solved the problem that existing structure can not all not import the light source that LED sends LGP with the light source that makes things convenient for LED to send.
Description of drawings
Fig. 1 is this practical structural representation;
1. wiring board, 2.LED, 3. reflectance coating, 4. LGP, 5. diffusion barrier 6. descends brightness enhancement film, increases film on 7., 8. anti-dazzling screen, 9. support.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further; But the claim of the utility model is not done any qualification.
Backlight ultra-thin light guide board light guide structure comprises wiring board 1, reflectance coating 3,4 compositions of LGP, it is characterized in that: support 9 the right be disposed with from bottom to up reflectance coating 3, LGP 4, diffusion barrier 5, down brightness enhancement film 6, on increase film 7, anti-dazzling screen 8; Described LGP 4 is designed to ladder-type structure, and the right of LGP 4 is provided with LED2, and the below of LED2 is provided with wiring board 1; LGP 4 height of light inlet equate with LED2 illuminating part open height.During practical implementation,, select suitable material for use, calculate the height of LGP 4 according to the backlight requirement; Design LGP 4 ladder, general ladder chamfer length is 1.5 millimeter, the LGP 4 of light inlet highly equals LED2 illuminating part open height; According to designing and manufacturing LGP 4 moulds,, again LGP 4 is assembled in the backlight through injection mo(u)lding; Energising makes LED2 send light source, passes light through LGP 4, utilizes reflectance coating 3 to carry out reflection source; Spread by top diffusion barrier 5 again, by brightness enhancement film 6 and last brightness enhancement film 7 are added lustre to the formation backlight down.
Claims (2)
1. backlight ultra-thin light guide board light guide structure; Comprise that wiring board (1), reflectance coating (3), LGP (4) form, it is characterized in that: support (9) the right be disposed with from bottom to up reflectance coating (3), LGP (4), diffusion barrier (5), down brightness enhancement film (6), on increase film (7), anti-dazzling screen (8); The right of described LGP (4) is provided with LED2, and the below of LED2 is provided with wiring board (1).
2. backlight ultra-thin light guide board light guide structure according to claim 1 is characterized in that: described LGP (4) is designed to ladder-type structure, and the LGP of light inlet (4) height equates with LED (2) illuminating part open height.
