Abstract
The utility model discloses a diffusion barrier is gone into light side and is fallen structure of making an uproar, it includes preceding light source, back light source, go out the plain noodles, go up the blast mould, lower brightness enhancement film, under expand the membrane, the light guide plate, the site layer, the reflective membrane, the black piece of gluing, preceding light source, back light source lies in the both sides of reflective membrane respectively, preceding light source, back light source is all just to the light guide plate of membrane, the site level is below the light guide plate, the reflectance coating is located the below on site layer, expand the top that the membrane is located the light guide plate down, brightness enhancement film is located the top of expanding the membrane down, it is located brightness enhancement film's top down to go up brightness enhancement film, it lies in brightness enhancement film's top and lie in the top of whole membrane to go out the plain noodles, a black top that is located the light guide plate of gluing, black glue the piece and expand the membrane down continuous. The utility model discloses it softly spreads in the main region in the center of backlight to enable the diffusion barrier to block the partly light of partly light and absorption in income light side reason, the reduction marginal ray reduces the effect of diffusion barrier marginal ray diffraction, and the stimulation to people's vision is reduced to apparent landing.
Description
Technical field
The present invention relates to a kind of diffusion mechanism, particularly relate to a kind of diffusion barrier incident side denoising structure.
Background technology
Be well known that at present, diffusion barrier can very soft disseminating in the center main region of backlight, but have a large amount of light diffractions at incident side edge.The peripheral vision weak effect of backlight.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of diffusion barrier incident side denoising structure, which overcomes the problem that light source that LED can not send by existing diffusion barrier carries out edge treated, reduces into the stimulation of sidelight line to people's vision.
The present invention solves above-mentioned technical matters by following technical proposals: a kind of diffusion barrier incident side denoising structure, it comprises front light-source, rear light source, exiting surface, upper blast mould, lower brightness enhancement film, lower expansion film, light guide plate, site layer, reflective membrane, black blob of viscose, front light-source, rear light source lays respectively at the both sides of reflective membrane, front light-source, rear light source is all just to the light guide plate of film, site layer is positioned at below light guide plate, reflectance coating is positioned at the below of site layer, lower expansion film is positioned at the top of light guide plate, lower brightness enhancement film is positioned at the top of lower expansion film, upper brightness enhancement film is positioned at the top of lower brightness enhancement film, exiting surface is positioned at the top of brightness enhancement film and is positioned at the top of whole film, black blob of viscose is positioned at the top of light guide plate, black blob of viscose is connected with lower expansion film.The light source that LED sends, biography light is carried out by light guide plate, the site layer at the light guide plate back side and reflectance coating is utilized to carry out reflection source, spread by lower expansion film again, added lustre to by lower brightness enhancement film and upper brightness enhancement film, form backlight, two light are provided, black blob of viscose is added in described diffusion barrier light inlet design, the diffusion barrier marginal ray of light inlet is weakened, reaches the effect of noise reduction.
Preferably, the thickness of described upper blast mould is equal with the thickness of lower brightness enhancement film.
Preferably, the thickness of described upper blast mould is greater than the thickness of lower expansion film.
Preferably, the thickness of described lower expansion film is greater than the thickness of site layer.
Preferably, the thickness of described site layer is greater than the thickness of reflective membrane.
Positive progressive effect of the present invention is: the present invention adds a black blob of viscose at diffusion barrier light inlet, make diffusion barrier can very soft disseminating in the center main region of backlight, and an incident side edge barrier part light and absorb a part of light, weaken marginal ray, reduce diffusion barrier edge-light diffraction, process entering sidelight line, and reduce the stimulation to people's vision significantly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Present pre-ferred embodiments is provided, to describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of diffusion barrier incident side of the present invention denoising structure comprises front light-source 1, rear light source 2, exiting surface 3, upper blast mould 4, lower brightness enhancement film 5, lower expansion film 6, light guide plate 7, site layer 8, reflective membrane 9, black blob of viscose 10, front light-source 1, rear light source 2 all lays respectively at the both sides of reflective membrane, front light-source 1, rear light source 2 is just to the light guide plate 7 of film, site layer 8 is positioned at below light guide plate 7, reflectance coating 9 is positioned at the below of site layer, lower expansion film 6 is positioned at the top of light guide plate 7, lower brightness enhancement film 5 is positioned at the top of lower expansion film 6, upper brightness enhancement film 4 is positioned at the top of lower brightness enhancement film 5, exiting surface 3 is positioned at the top of brightness enhancement film 4 and is positioned at the top of whole film, black blob of viscose 10 is positioned at the top of light guide plate 7, black blob of viscose 10 is connected with lower expansion film 6.The light source that LED sends, biography light is carried out by light guide plate 7, the site layer 8 at the light guide plate back side is utilized to carry out reflection source with reflectance coating 9, spread by lower expansion film 6 again, added lustre to upper brightness enhancement film 4 by lower brightness enhancement film 5, form backlight, two light are provided, black blob of viscose 10 is added in described diffusion barrier light inlet design, the diffusion barrier marginal ray of light inlet is weakened, reaches the effect of noise reduction.The thickness of upper blast mould 4 is equal with the thickness of lower brightness enhancement film 5.The thickness of upper blast mould 4 is greater than the thickness of lower expansion film 6.The thickness of lower expansion film 6 is greater than the thickness of site layer 8.The thickness of site layer 8 is greater than the thickness of reflective membrane 9.The effect of above-mentioned thickness structure is best, saves material most, and cost is low.
Above-described specific embodiment; the technical matters of solution of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
