Abstract
The invention relates to a brightness enhancement film for a flat panel display, which is formed by directly impressing patterns on an optical film. The structure directly impresses the patterns on the optical film, reduces the difference between the refraction index and light transmittance caused by different materials between the optical film and a coating, and improves the brightening degree. In addition, the material cost is reduced due to needing no coating. In order to produce the brightness enhancement film for the flat panel display, a production method is to directly treat optical film plastic particles, and then directly impress the patterns on the formed optical film. The method reduces production steps. Moreover, products produced by the method only relate to a material, so the brightening degree is improved, and high-quality products are obtained by fewer steps.
Description
Technical field
The present invention relates to a kind of optical thin film and manufacture method thereof, be specifically related to good optical film for plane display of a kind of light enhancing effect and manufacture method thereof.
Background technology
A kind of brightness enhancement film through ridge type pattern is arranged in the market, and this pattern increases effective sunlight by collecting light source, reaches the purpose that strengthens optical thin film brightness, is widely used on the display.But its shortcoming is: the production of this kind brightness enhancement film is one or more layers coating of coating on a kind of plastic film substrate, on coating, carry out operations such as embossing again, replant the inconsistent of the light transmission of plastic material and coating and refractive index, cause the variation of light trend and the reduction of transmittance easily.
Summary of the invention
Main task of the present invention is to provide a kind of optical film for plane display and manufacture method thereof, specifically is good optical film for plane display of a kind of light enhancing effect and manufacture method thereof.
In order to solve above technical matters, a kind of optical film for plane display of the present invention is made of optical thin film, and its innovative point is: impression has pattern on the described optical thin film.
In order to make this product, a kind of method of making optical film for plane display, its manufacturing step is as follows: a, select materials: with the plastic pellet of optical thin film: toughner: levelling agent: opening agent=98-99:0-1:0-1:0-1; (weight ratio) b, send to after above-mentioned raw materials mixed and extrude slobbering machine and heat, be waterfall shape and flow out, form the optical thin film blank from the hydrostomia die head to molten condition; C, with the optical thin film blank through the laggard capable decorative pattern compacting of cooling just after, promptly cool off the mold pressing embossing once-forming.The temperature of plastic pellet molten condition is in the described b step: 240-300 ℃.
First cooling process in the described C step for the optical thin film blank through two minute surface steel riders suppress optical thin film, in pressing process, realize cooling just.
The described temperature of cooling just is: 200-260 ℃.
The thickness 30um-240um of described optical thin film.
Decorative pattern in the described C step is compressed to: the optical thin film after will just lowering the temperature is suppressed formation again between two pair rollers.
Described two pair rollers are that a minute surface steel rider and a surface have the steel rider formation of pattern.
The advantage of above product and manufacture method thereof is: at first, product is by original other coatings that is coated with on optical thin film, the blank of imprinted pattern becomes and now directly the plastic pellet of optical thin film is handled on coating then, directly prints off pattern then on optical thin film.
The advantage of this product is: direct imprinted pattern on optical thin film, reduce the refractive index that causes because of material not of the same race between optical thin film and the coating and the difference of transmittance, and improve the blast degree, in addition, owing to do not need coating, the minimizing material cost.
The advantage of this product processes is: adopt this method to produce product, only need carry out the processing of optical thin film plastic pellet, then directly on the optical thin film that forms imprinted pattern get final product, the product that production stage reduces, also produces owing to this method only relates to a kind of material, therefore, the blast degree improves, and with less step, has obtained the more product of high-quality.

Fig. 2 is a process chart of the present invention;
Fig. 3 is the structural representation of pattern on the optical thin film of the present invention.
Embodiment
As shown in Figure 1, the present invention constitutes for impression on optical thin film 1 has pattern 2.In order to make the brightening effect of this optical thin film 1 better, can be chosen in direct imprinted pattern 2 on the optical thin film body 1, guarantee the unicity of optical thin film material; And pattern 2 is designed to the tapered pattern of platform that the top is a sphere, as shown in Figure 3.Utilize the platform cone body and the spherical surface body of pattern 2, multidirectional gathering light source is collected more effectively light, reaches brightening effect.
It below is the manufacture method of product of the present invention.As shown in Figure 2, production stage is as follows: at first, select materials earlier: with the plastic pellet of optical thin film: toughner: levelling agent: opening agent ...=98-99:0-1:0-1:0-1 weight ratio.The plastic pellet of optical thin film in the present embodiment: toughner: levelling agent: opening agent ... send to extrude after=98-99:0-1:0-1:0-1 fully mixes above-mentioned raw materials then and heat in the slobbering machine to molten condition, this moment, temperature was between 240-300 ℃, then plastic pellet is extruded and be waterfall shape and flow out, form the optical thin film blank from slobbering machine die head 3; Again the optical thin film blank is passed through a pair of minute surface pressure roller A, B to being pressed into the optical thin film of thickness at 30um-240um, in this process, temperature drops between 200-240 ℃, has realized first cooling process; At last, the optical thin film of cooling just had between the pair roller that the steel rider C of pattern forms from minute surface steel rider B and surface again suppress, on the one side of optical thin film, form press pattern, be cooled to normal temperature, form finished product.
