20090040431 | Liquid crystal display panel with improved image contrast - The present invention relates to a liquid crystal display panel with improved image contrast comprising an array of pixel regions and a sequence of a recycling backlight structure comprising broadband rear interference polar (RI-Polar) having a transmission axis AB with preset orientation, a spatial intensity modulation structure comprising a broadband front interference polar (FI-Polar) having a transmission axis approximately parallel to the transmission axis AB, a spectral filtering structure, and antireflection means. Each said pixel region spatially encompasses a plurality of subpixel regions. The RI-Polar and FI-Polar are multilayer structures of stacked layers. At least one layer of each structure is optically anisotropic, made by means of Cascade Crystallization Process and characterized by a globally ordered biaxial crystalline structure with an intermolecular spacing of 3.4±0.3 Å in the direction approximately parallel to the transmission axis AB. Said layer is transparent in the wavelength band of visible light, and is formed by rodlike supramolecules, which represent at least one polycyclic organic compound with a conjugated π-system and ionogenic groups. | 02-12-2009 |
20140081070 | Biodegradable Multilayer Constructs - Embodiments of the present invention relate generally to the field of tissue repair and regeneration. More specifically embodiments of present disclosure relate to devices or constructs and methods to prepare various devices or constructs useful in directing cellular repair and controlling tissue regeneration to prevent or minimize postsurgical or post traumatic adhesions, excessive scars and/or fibrotic reactions of injured tissues. | 03-20-2014 |
20140242347 | Graft For Directed Vascular And Lymphatic Regeneration And Methods To Guide Endothelial Cell Assembly - Embodiments of the present invention relate to a therapeutic device (graft) comprising a collagen membrane having an aligned uniaxial or biaxial structure such that mammalian cells plated on the membrane align mainly along the direction of the collagen fibrils. In a further aspect, a graft comprising a substantially tubular body, wherein the body has an exterior surface, an interior surface, and at least one lumen extending therethrough such that a fluid flow through the lumen can direct mammalian cell migration. In a further aspect, mammalian cells or growth and angiogenic factors can be optionally attached to the exterior and/or interior surface of the substantially tubular body. In various aspects, the graft can be used as a vascular prosthesis, a stent, or a nerve regeneration scaffold. Methods of preparing and implanting same are also provided. | 08-28-2014 |
