The utility model discloses a diffusion barrier can very soft spreaing in the main region in center of backlight, and the light side of turning over simultaneously blocks partly light along black printing ink piece and absorb partly light that the reduction marginal ray reduces diffusion barrier marginal ray diffraction to go into the sidelight line and handle counter, showing the stimulation that reduces people's vision.
Description
Technical field
The utility model relates to a kind of diffusion barrier, particularly relates to the anti-incident side denoising structure of a kind of diffusion barrier.
Background technology
Light guide plate (lightguideplate) is the acrylic/PC sheet material utilizing optical grade, then with having high reflectivity and the hitech materials of not extinction, stamps light guiding points at the acryl plates bottom surface UV screen printing technology of optical grade.Utilize optical grade acryl plates to draw the stop of light on optical grade acryl plates surface sent from lamp, when light is mapped to each light guiding points, reflected light toward all angles diffusion, then can destroy conditioned reflex and is penetrated by light guide plate front.By various density, light guiding points not of uniform size, light guide plate uniformly light-emitting can be made.The purposes of reflector plate is that the light exposed bottom surface is reflected back in light guide plate, is used for improving the service efficiency of light; With in homalographic luminosity situation, luminescence efficiency is high, low in energy consumption.One side micro structure array light guide plate generally adopts the manufacture craft of ejection formation.
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 anti-incident side edge.The peripheral vision weak effect of backlight.
Summary of the invention
Technical problem to be solved in the utility model is to provide the anti-incident side denoising structure of a kind of diffusion barrier, overcomes the problem that light source that LED can not send by existing diffusion barrier carries out edge treated, significantly reduces the stimulation to people's vision.
The utility model solves above-mentioned technical matters by following technical proposals: the anti-incident side denoising structure of a kind of diffusion barrier, it comprises light source, exiting surface, upper brightness enhancement film, lower brightness enhancement film, diffusion barrier, light guide plate, mesh layer, reflectance coating, black ink block, light source is positioned at the side of reflectance coating also just to light guide plate, light guide plate is between diffusion barrier and mesh layer, mesh layer is positioned at below light guide plate, under reflectance coating is positioned at mesh layer, lower brightness enhancement film is positioned on diffusion barrier, upper brightness enhancement film is positioned in lower brightness enhancement film, exiting surface is positioned at above brightness enhancement film, black ink block is positioned at above light guide plate, black ink block is connected with diffusion barrier, black ink block is positioned at the anti-incident side of light guide plate.The light source that LED sends, biography light is carried out by light guide plate, the site of site, light guide plate back side layer and reflectance coating is utilized to carry out reflection source, spread by diffusion barrier again, added lustre to by lower brightness enhancement film and upper brightness enhancement film, form backlight and provide light, diffusion barrier anti-light inlet design and printing black ink block for film, the diffusion barrier marginal ray of anti-light inlet is weakened, reaches Noise Reduction.
Preferably, the thickness of described exiting surface is greater than the thickness of brightness enhancement film.
Preferably, the thickness of described upper brightness enhancement film is equal with the thickness of lower brightness enhancement film.
Preferably, the thickness of described lower brightness enhancement film is less than the thickness of diffusion barrier.
Preferably, the thickness of described diffusion barrier is less than the thickness of light guide plate.
Preferably, the thickness of described reflectance coating is less than the thickness of lower brightness enhancement film.
Positive progressive effect of the present utility model is: design a black ink block at the anti-light inlet of diffusion barrier, make diffusion barrier can very soft disseminating in the center main region of backlight, stop the light of a part at anti-incident side edge black ink block simultaneously and absorb a part of light, weaken marginal ray, reduce diffusion barrier edge-light diffraction, and to counter enter sidelight line process, significantly reduce the stimulation to people's vision.
