Abstract
The utility model relates to the good super-thin LED backlight of a kind of astigmatism, comprise the black and white double faced adhesive tape be cascading, upper water chestnut sheet, lower water chestnut sheet, diffusion barrier, light guide plate, glue frame and reflectance coating from top to bottom, described light guide plate top is provided with flexible circuit board, described flexible circuit board is provided with LED, described light guide plate is provided with salient point, described each water chestnut sheet distributes respectively some parallel water chestnut shape posts, and the direction of the water chestnut shape post on two water chestnut sheets differs 90 °.The super-thin LED backlight that a kind of light-dispersing effect is good, light extraction efficiency is good is provided.
Description
Technical field
The utility model relates to the good super-thin LED backlight of a kind of astigmatism, belongs to electric light source field.
Background technology
The light guide plate normally block surface plate of existing LED-backlit plate, light-dispersing effect is undesirable, and the brightening piece be positioned at above diffusion barrier is also planar structure usually, and light extraction efficiency is not good.
Because the cooling requirements of LED-backlit plate technique is higher, the thickness of LED-backlit plate light guide plate is in the market generally 0.6mm, LED thickness is 0.6mm, causes the integral thickness of LED-backlit plate comparatively large, has had a strong impact on radiating efficiency and the luminosity of LED-backlit plate.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, provides the super-thin LED backlight that a kind of light-dispersing effect is good, light extraction efficiency is good.
The utility model solves the technical scheme that its technical problem adopts: the super-thin LED backlight that a kind of astigmatism is good, comprise the black and white double faced adhesive tape be cascading, upper water chestnut sheet, lower water chestnut sheet, diffusion barrier, light guide plate, glue frame and reflectance coating from top to bottom, described light guide plate top is provided with flexible circuit board, described flexible circuit board is provided with LED, described light guide plate is provided with salient point, described each water chestnut sheet distributes respectively some parallel water chestnut shape posts, and the direction of the water chestnut shape post on two water chestnut sheets differs 90 °.
The thickness of described light guide plate is 0.25mm.
The thickness of described LED is 0.2mm.
Beneficial effect:
(1) on light guide plate, set up salient point, improve light-dispersing effect;
(2) brightening piece adopts double-deck water chestnut chip architecture, greatly improves light extraction efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Detailed description of the invention
The super-thin LED backlight that a kind of astigmatism is as shown in Figure 1 good, comprise the black and white double faced adhesive tape 1 be cascading, upper water chestnut sheet 2, lower water chestnut sheet 3, diffusion barrier 4, light guide plate 7, glue frame 8 and reflectance coating 9 from top to bottom, described light guide plate 7 top is provided with flexible circuit board 5, described flexible circuit board 5 is provided with LED 6, described light guide plate 7 is provided with salient point 10, the direction of the water chestnut shape post 11 described each water chestnut sheet distributed respectively on some parallel water chestnut shape post 11, two water chestnut sheets differs 90 °.The thickness of described light guide plate 7 is 0.25mm, and the thickness of described LED 6 is 0.2mm.
Directly be attached on light guide plate 7 after upper water chestnut sheet 2, lower water chestnut sheet 3 and diffusion barrier 4 superpose, then black and white double faced adhesive tape 1 overlayed on the superiors, be bonded at above glue frame 8, compress.Black and white double faced adhesive tape 1 one aspect is used for shading, is used on the other hand pasting liquid crystal display.Reflectance coating 9 is positioned at the bottom, by double faced adhesive tape bottom glue frame 8.
Should be appreciated that specific embodiment described above only for explaining the utility model, and be not used in restriction the utility model.Still be among protection domain of the present utility model by spirit institute's apparent change of extending out of the present utility model or change.
