Title: Joseph John Bianconi: Innovator in Optical Technologies
Introduction
Joseph John Bianconi is a notable inventor based in Saint Paul, MN (US). He has made significant contributions to the field of optical technologies, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
Bianconi's latest patents include a "Method for stacking surface structured optical films" and an "Optical waveguide with diffuse light extraction." The first patent describes a display that incorporates an optical film with a structured surface designed to enhance brightness. This structured surface is bonded to a second film using an adhesive layer, which penetrates the structured surface to a depth less than the feature height. This innovative bonding method not only strengthens the films but also minimizes the risk of damage during assembly. The second patent details an optical waveguide featuring a core and cladding, where the inner surface of the cladding is roughened non-uniformly to facilitate the extraction of diffuse light. The core is made from a light-transmitting material, and the cladding surrounds it with a lower index of refraction. The roughened inner surface of the cladding, which can be created through various methods, helps to extract light effectively from the core.
