Abstract
The utility model discloses a non-woven fabric diffuser with a coating. The diffuser comprises the surface optical coating and a non-woven fabric body, wherein the surface of the non-woven fabric body is uniformly coated with the surface optical coating, or the surface optical coating is penetrated into the non-woven fabric body via the surface, and the surface optical coating is a vinyl acetate coating, an acrylic acid coating or an OCA coating. Due to the above mode, the non-woven fabric diffuser with the coating provided by the utility model is excellent in light diffusion uniformity, low in light intensity loss, low in weight, convenient to install and high in cost performance, and can be widely applied to the fields as display backlight, light illumination, and billboard lamp boxes.
Description
Technical field
The utility model relates to light diffusion sheet field, particularly relates to a kind of nonwoven fabrics diffusion sheet of coating.
Background technology
The Main Function of liquid crystal display backlight is to provide a planar light source uniform, stable, that have certain brightness.The core light source of internal light source is generally light emitting diode (LED), and inhomogeneous pointolite LED being sent through light guide plate and diffusion sheet is converted into uniform area source.
As critical piece, the effect of diffusion sheet in backlight is obvious, and what most liquid crystal display adopted is the diffusion sheet for former material by other transparent polyester film of optical grade (PET).In order to optimize the optical property of diffusion sheet, generally all can carry out some surface treatments on transparent polyester film diffusion sheet surface, the most common mode is some optical coatings of coating, reach the object of optimizing its optical property, but transparent polyester film diffusion sheet complex process, cost are higher, and adopt the integral thickness of the liquid crystal display of transparent polyester film diffusion sheet to can not get further control.
In addition, in lighting (desk lamp, ceiling light, outdoor lighting etc.), being used for the material of uniform light mostly is atomization glass (ground glass) or frosted acrylic cover plate, the starting material that advertising lamp box cloth uses mostly are organic glass colour table or pvc plate, volume is thick and heavy, cost is high, installation and renewal cost are large, and security is not high, poor optical properties.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of nonwoven fabrics diffusion sheet of coating, and quality is frivolous, and light diffusion uniformity is good, and cost is low, and light intensity losses is few.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the nonwoven fabrics diffusion sheet that a kind of coating is provided, comprise: surface optics coating and nonwoven fabrics matrix, described surface optics coating is uniformly coated on the surface of nonwoven fabrics matrix or infiltrates into nonwoven fabrics matrix inside by surface, and described surface optics coating is vinyl acetate coating, acrylic acid coatings or OCA optical cement coating.
In preferred embodiment of the utility model, described surface optics coating is coated on the one side of nonwoven fabrics matrix or two-sided.
In preferred embodiment of the utility model, described nonwoven fabrics matrix is the nonwoven fabrics that single kind synthon or multiple fiber are mixed.
In preferred embodiment of the utility model, the thickness of described nonwoven fabrics is 0.05mm ~ 1mm.
In preferred embodiment of the utility model, the thickness of described surface optics coating is 0.001mm ~ 0.5mm.
The beneficial effects of the utility model are: the nonwoven fabrics diffusion sheet of a kind of coating that the utility model is pointed out, good to the diffusion uniformity of light, light intensity losses is little, can be widely used in the fields such as display backlight source and lighting, billboard light box, quality is slim and graceful, easy for installation, cost performance is high.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of nonwoven fabrics diffusion sheet one preferred embodiment of a kind of coating of the utility model;

In accompanying drawing, the mark of each parts is as follows: 1, surface optics coating, 2, nonwoven fabrics matrix.
Embodiment
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model embodiment comprises:
A kind of nonwoven fabrics diffusion sheet of coating, comprise: surface optics coating 1 and nonwoven fabrics matrix 2, described surface optics coating 1 is uniformly coated on the surface of nonwoven fabrics matrix 2 or infiltrates into nonwoven fabrics matrix 2 inside by surface, and described surface optics coating 1 is vinyl acetate coating, acrylic acid coatings or OCA optical cement coating.
The nonwoven fabrics diffusion sheet pattern of a kind of coating of the utility model has two kinds, distinguishes and is coated on the one side of nonwoven fabrics matrix 2 or two-sided for described surface optics coating 1.Fig. 1 is the nonwoven fabrics diffusion sheet of one side coating, the nonwoven fabrics diffusion sheet that Fig. 2 is double spread, and practical application is more flexible, suits measures to local conditions, and saves manufacturing cost and use cost.
Enter one, described nonwoven fabrics matrix 2 plants for single the nonwoven fabrics that synthon or multiple fiber are mixed, and quality is slim and graceful, with low cost, and THICKNESS CONTROL is flexible.
Enter one, the thickness of described nonwoven fabrics is 0.05mm ~ 1mm, be widely used in the fields such as mobile phone, liquid crystal TV set display backlight source and lighting, billboard light box outer cover.
Enter one, the thickness of described surface optics coating 1 is 0.001mm ~ 0.5mm, according to actual needs, makes the diffusion sheet of multiple optical property, meet various customer requirements.
In sum, the nonwoven fabrics diffusion sheet of a kind of coating that the utility model is pointed out, compared with transparent polyester film diffusion sheet, technique is simple, with low cost, and quality is frivolous, contribute to reduce the thickness of liquid crystal indicator, be applied in addition illuminating lamp shade or advertising lamp box field, can improve transmitance and the homogeneity of light, reduce the weight of device, easy construction, security performance is high.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
