For example, when a light ray 93 is incident on the substrate 91 at a relatively large incident angle with respect to the second surface of the substrate 91 (that is, the light ray 93 is less perpendicular to the second surface of the substrate 91), the light 93 can smoothly refract the prism unit 92 that emits the first surface of the substrate 91.

Further, as shown in FIG. 4a, in the composite concentrating sheet 1 having diffusing particles according to another preferred embodiment of the present invention, the first inclined surface 12a and the second inclined surface of the curved prism unit The face 12b (i.e., at least one curved extension surface) may be further selected to form a plurality of side ridges 121 having interdigitated shapes to selectively exhibit a continuous change, the same surface curvature change, or a different surface curvature change. Referring to FIGS. 3 and 4 again, the substrate u sin and curved prism unit 12 of the preferred embodiment of the present invention may be fabricated by the same transparent material of the same transparent material; or the substrate 11 and the curved prism The unit 12 can also be made of different light-transmissive materials by lamination, stamping, rolling or molding to meet different characteristics or manufacturing requirements, and to increase the scope of application and manufacturing margin of the invention. . For example, the substrate 11 can be obtained from various flexible transparent substrates selected from the group consisting of polyethylene terephthalate (PET), polyethylene (PE), and polyethylene naphthalate. At least one of ester (PEN), polycarbonate (PC), polyvinyl alcohol (PVA), polyethene (PVC), and other high molecular polymers or a composition thereof. The tube prism unit 12 is preferably available from a UV curable glue (UV glue). Referring again to FIGS. 3 and 4, a preferred embodiment of the present invention is shown with reference to a 500-fold photomicrograph of a microscope having a composite concentrating sheet having diffusing particles according to a preferred embodiment of the present invention. For example, the diffusion particles 13 are randomly mixed in a predetermined ratio in the material of the curved prism unit 12, and the weight ratio of the diffusion particles 13 to the curved prism unit π is preferably about 1% to 35%. Between, especially between ι〇 / ◦ to 25%. This diffusion C:\Linda\PK PatSPKlOI32. doc — 11 — 130, 1 30, No. 95138641, the patent specification. - the particles 13 are preferably made of a material different from the curved prism unit 12, 'for example, from an acrylic material and/or a glass material, the vitreous material may be further selected from the group consisting of oxidizing materials.矽(Si〇2), bismuth oxide (Al2〇3), oxidized (B2〇3), calcium oxide (Ca〇), magnesium oxide (Mg〇), silicone resin, polyester resin ( At least one of p〇iyester resin) and styrene-type isU^styrene resin or a composition thereof. Therefore, at the time of preparation, the present invention may be blended by any conventional blending method, for example, an acrylic material or a vitreous material may be appropriately mixed in an amount of 1 to 35 weight units per 100 weight units of the ultraviolet curable adhesive. A structure of the curved prism unit 12 doped with the diffusion particles 13 is prepared. Furthermore, the average particle diameter of the diffusion particles 13 is preferably maintained between 〇5//m (micrometer) and 3 (^111, especially the average particle diameter is between 〇.5/zm (micrometer) to l〇. /zm ^, at least one of or in combination with an elliptical shape, an elliptical shape, an ellipsoidal shape, an ovate shape, and an irregular polyhedral shape. Referring to Figures 3, 4 and 5, in the preferred embodiment of the present invention In the light sheet 1, the first inclined surface 12a and the second inclined surface 12b of the curved prism unit 12 may be the same or different, but at least one of the first inclined surface and the second inclined surface 12b is selected from a curved shape. Extending the curved surface, which can form a regular or irregular undulating curvature, in a yield, which is advantageous for guiding at least two-dimensional refraction of the ray 14 or 15 emitted by the second surface 11bt of the substrate. The materials are different, and the secrets 13 of the present disclosure are not mixed or regulated in the curved: curved prism unit 12, and the intersection of each of the diffusing particles 13 and the curved prism unit 12 is C:\Lincta\PK Pat\ PKI〇|3i doc —12 — 130130 Patent Specification No. 95138641 Correction This interface (not labeled) provides a light fold The interface causes the light 14 or 15 to form a variety of refractions and scattering by the interface to increase the probability of diffusion and angle change. Therefore, as shown in FIG. 5, the light 14 is opposite to the substrate 11 The two surfaces lib are incident on the substrate η at a large incident angle (that is, the light 14 is less perpendicular to the second surface Ub of the substrate U), or the light 15 is opposite to the second surface Ub. a smaller incident angle (less than 6 to 9°) is incident on the substrate 11 (ie, the light 15 is perpendicular to the second surface of the substrate u), and the light rays 14 and 15 can be diffused by the diffusion particles. 13 changing the angle causes a diffusion effect, and the rays 14 and 15 also generate a myriad of diffusion splitting by the diffusing particles 13 to correct the exit angle and the concentrated light, so that the first tilt of the curved prism unit 12 can be smoothly refracted. The surface 12a and the first inclined surface 12b' can simultaneously reduce the haze and the modified structure, and the diffusion particles 13 of the present invention can effectively reduce the probability of the total anti-f of the light. Furthermore, the curved prism unit 12 - the inclined surface 12a and the second inclined surface 12b may also The curvature of the surface is curved to reduce the total reflection of the light, and the scattered light that has been diffused by the primordial, thereby increasing the brightness of the concentrating sheet, thereby showing the preferred embodiment of the present invention as shown in FIG. "Comprehensive concentrating of expanded particles" - secondary light transmittance and reflectivity 2-line diagram. The present invention can significantly increase the ray 14 and 15 times: by efficiency and reducing the light loss rate, that is, By using the existing UV curing material to mix the diffusion particles, the small angle of the person can pass the light through the expansion particles, and the (4) her single correction angle and set C:\LiiHta\HC P»t\PI {|〇|3a d〇c —13 — 13 Ο'15ΐ4β· 30 Patent specification No. 95138641 corrects this β • + light, and then emits from the first surface to increase the “secondary light: f transmittance” The light that is reduced in small angles is "total reflection", which reduces the "light loss rate" and obtains at least two-dimensional polyhedron. As shown in FIG. 7, the composite concentrating sheet 1 having diffusing particles (the curved prism unit 12 including the diffusing particles 13) of the preferred embodiment of the present invention in FIG. 5 and the conventional concentrating of FIG. 2 are disclosed. A comparison chart of the primary light transmittance of the sheet 9 (prism unit without diffusing particles). Compared with the conventional concentrating sheet 9 of Fig. 2, the increase in the secondary penetration efficiency of the condensing sheet 1 of the present invention is between about 1% and about 9%. At the same time, it can also improve the uniformity of the light source and modify the light source, increase the uniformity of luminance, increase the half-luminance angle of horizontal and vertical, increase the viewing angle and the high luminance of the large viewing angle, and modify it with higher haze. The fine structure of the condensing sheet 1 is reduced in order to improve the yield of the finished product and to reduce the manufacturing surface. In particular, since the condensing sheet 1 alone can uniformly scatter the human light, if a illuminating sheet i of the present invention is used in a backlight module (not shown), the δ can be set to any diffusion. The film may reduce the need for the diffusion sheet, so that the invention also has the advantages of simplifying the backlight module and reducing the assembly cost of the rear stage. Please refer to Figures 8 and 9 for comparing the concentrating sheets of the preferred embodiment of the present invention (the present invention in Figures 8 and 9) and a conventional concentrating sheet containing no diffusing particles (8th and 9th). In the case of the previous figure, the horizontal and vertical viewing angle luminance values in the state in which the two sheets are superimposed. As shown in Figures 8 and 9, the experimental results are as follows: in the state of "only the lower diffuser", the luminance value is the lowest value; 'through the mixing of different proportions of the diffusion particles, the state of the "double sheet" in this case That is, there is an optical brightness performance and diffusion capability superior to that of the "front case double + lower diffusion sheet", and since the condensing sheet of the preferred embodiment of the present invention has a higher "haze" C:\Linda\f1C Pet\PK10l3adoc — 14 — Ofi/11/30/11:20 , \Η 13015481.30 Amendment to Patent Specification No. 95138641. 'Advantages, so you can additionally achieve the effect of modifying the "structure 暇疵"; similarly, . Through the mixing of different proportions of diffusing particles, compare "double sheet + upper diffuser -" and "front case double + upper and lower" In the state of the diffuser, the luminance value curve of "double sheet + upper diffuser in this case" has an upward trend; in addition, the brightness value reaches the highest value in the state of "two cases in the case + the former case - sheet". That is to say, the use of "one case + the previous case - Zhang" has better photonics than other states, and the effect of the conventional concentrating film can be achieved without using the lower diffusion sheet. In this case, the double-frame structure can be used without the use of Shang, Lu #, to achieve the effect of the conventional concentrating film, including the function of modifying the fatigue and scavenging the light source.

The concentrating sheet 9 used in the second embodiment is more likely to be re-exposed from the second surface of the substrate 91 due to the total reflection of the light 94, thereby reducing the short-passing efficiency of the light 94 and increasing the light loss rate.
