Abstract
The invention discloses a diffusion film incident light reflection side noise reduction structure comprising a light source, a light-out surface, an upper brightness enhancement film, a lower brightness enhancement film, a diffusion film, a light guide plate, a mesh layer, a reflective film, and a black ink block. The light source is disposed at one side of the reflective film, and directly faces the light guide plate. The light guide plate is disposed between the diffusion film and the mesh layer. The mesh layer is disposed under the light guide plate. The reflective film is disposed under the mesh layer. The lower brightness enhancement film is disposed on the diffusion film. The upper brightness enhancement film is disposed on the lower brightness enhancement film. The light-out surface is disposed on the upper brightness enhancement film. The black ink block is disposed on the light guide plate, is connected with the diffusion film, and is disposed at the incident light reflection side of the light guide plate. The diffusion film can diffuse light softly in the main area of the center of a backlight source, and the black ink block on the edge of the incident light reflection side blocks part of light and absorbs part of light, so that the edge light is weakened, and diffraction of light at the edge of the diffusion film is reduced. Light at the incident light reflection side is processed, which significantly reduces visual stimulation to people.
Description
Technical field

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 matters to be solved by this invention 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 present invention solves above-mentioned technical matters by following technical proposals: the anti-incident side denoising structure 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.
