Title: The Innovations of Charles Rosenblatt
Introduction
Charles Rosenblatt is a notable inventor based in Beachwood, OH (US). He has made significant contributions to the field of liquid crystal displays, holding a total of four patents. His work focuses on enhancing the performance of display technologies through innovative materials and fabrication techniques.
Latest Patents
Rosenblatt's latest patents include the development of an organic polymer O-plate compensator designed to improve gray scale performance in twisted nematic liquid crystal displays. This O-plate compensator comprises an organic liquid crystal polymer and involves methods for its fabrication. The compensator is characterized as a uniaxial birefringent thin film, with its extraordinary axis oriented obliquely to the film's surface. The oblique orientation of the liquid crystal director, which aligns with the film's extraordinary axis, is achieved by casting an organic thin film onto a specially prepared surface for orienting liquid crystals. This process can utilize either a solution of the liquid crystal polymer or a reactive liquid crystal monomer. The fabrication process ensures that any solvent used is evaporated, and the organic thin film is maintained at a temperature within its nematic phase. If a reactive monomer is employed, the film undergoes photopolymerization. Alternative embodiments of the organic O-plate also explore the use of smectic-A and smectic-C materials, with various fabrication techniques described.
