    摘要: The present invention relates to a method for preparing an optical sheet comprising the steps of: (a) preparing a transfer film having a single roughened side by coating one side of a first substrate with resin component comprising 100 parts by weight of binder resin and 70 to 130 parts by weight of spherical organic polymer beads, followed by drying; (b) laminating the transfer film preparing in step (a) with an ultraviolet-curable (UV-curable) resin-coated layer, which prepared by coating one side of a second substrate with UV-curable resin, such that the roughened side of the transfer film is facing the UV-curable resin-coated side of the second substrate; and (c) forming a roughened diffusive layer on the single-side of the second substrate having refractive index of 1.41 to 1.59 by curing the laminate obtained in step (b), followed by separating and removing the transfer film, wherein the roughened side of the transfer film has a segment angle of 130 to 150°. The optical sheet prepared by the method of the present invention has high brightness, which can also provide masking of prism sheet pattern, and is safe from surface stains and interface scratches between the sheet and the polarizing plate positioned underneath, thus, can be used as an optical sheet in backlight unit of LCD.

    摘要: Disclosed is an LED lighting system comprising a housing equipped with a transparent substrate as an illuminating side, an LED light source located in the housing, and a haze-changeable film attached to the transparent substrate, wherein the transparency of the haze-changeable film changes depending on the application of electric power and the haze-changeable film has a haze on light varying with the intensity of an applied voltage/current. The LED lighting system may be useful for interior emotional lighting because a direct/indirect lighting and a mixed lighting thereof can be provided with a single system and various correlated color temperatures can be produced with a single LED light source.

    摘要: The present invention provides a composite light guide plate having a thickness of more than about 1 mm, for use in LCD backlights or in general illumination devices. In the fabrication method of the present invention the extrusion roll molding process is combined with coating and lamination steps to enable a cost effective roll-to-roll or roll-to-sheet manufacture of the thick composite light guide plate wherein one or both principal surfaces of the light guide plate contain a pattern to enable extraction and redirection of light by the light guide plate from a light source or multiple light sources placed at one or multiple edges of the light guide plate. The composite light guide plate comprises a patterned film and a pre-cut sheet joined together by an adhesive layer. In order to attain good light extraction efficiency the adhesive layer and the two constituent layers of the light guide plate must be optically matched such that the refractive indices of any two of the three materials of the composite light guide plate can differ by no more than 0.01.
