Abstract: The present invention provides: an extracellular matrix of which the biocompatibility is greatly increased through fat removal and decellularization and which contains growth factors so as to control physiological activities of cells; and a method for preparing the same. In addition, the extracellular matrix may be effectively obtained through a solvent extraction process using supercritical fluid, and a preservation solution comprising the extracellular matrix may be preserved for a long time by preventing contamination, and has increased manageability so that usability of the extracellular matrix may be greatly increased.

Abstract: Provided are a complex optical film and a light source assembly including the same. The complex optical film includes a first substrate, a light shielding layer formed on a bottom surface of the first substrate, an optical pattern layer formed on a top surface of the first substrate and including concavo-convex portions, a second substrate disposed on the first substrate, and a first adhesive layer disposed under the second substrate, wherein the light shielding layer includes a binder and organic particles and inorganic particles dispersed in the binder, the convex portions of the optical pattern layer at least partially penetrate into the first adhesive layer to be combined with the first adhesive layer, and a low-refraction area having a lower refractive index than the optical pattern layer and the first adhesive layer is defined between the first adhesive layer and the optical pattern layer.

Abstract: An integrated light guide panel for use in a backlight unit for an LCD and a method for manufacturing the same are disclosed. The integrated light guide panel includes a light guide panel for guiding light, to form surface light, a reflective coating layer arranged beneath the light guide panel, to reflect light emerging from a lower surface of the light guide panel such that the light is again incident to the light guide panel, a diffusive coating layer arranged over the light guide panel, to diffuse light emerging from the light guide panel, a prism coating layer arranged over the diffusive coating layer, to concentrate light emerging from the diffusive coating layer, and low refractive coating layers respectively arranged between the light guide panel and the reflective coating layer and between the light guide panel and the diffusive coating layer.

Abstract: A prism sheet having a concave pentagonal structure is disclosed. The prism sheet comprises a base layer, and a prism array disposed on and supported by the base layer. The prism array is composed of a plurality of prisms aligned in parallel and one beside the other. The transversal cross-section of each prism has a shape of concave pentagon, which is symmetrical about a vertical line passing the apex. The interior angle ? of the apex is 30°???120°, the exterior angle ? formed by the upper slant side and the lower slant side is ?<180°, the interior angle ? of the lower vertex formed by the lower slant side and the base is 5°???85° and the length w of the base is 30 ?m?w?100 ?m. Preferably, the interior angle ? of the apex may be 40°???100°, the exterior angle ? formed by the upper slant side and the lower slant side may be 160°???179°, and the interior angle ? of the lower vertex formed by the lower slant side and the base may be 30°???60°. Preferably, the length w of the base may be 40 ?m?w?60 ?m.
