Latest Patents
John Havens holds a patent for "Plastic substrates for active matrix liquid crystal display incapable of." This patent describes a method for forming bright-polarizer-free active-matrix liquid crystal displays (AMLCDs) on plastic substrates. The display consists of a pixel circuit fabricated on one plastic substrate, an intervening liquid-crystal material, and a counter electrode on a second plastic substrate. The pixel circuit includes one or more thin-film transistors (TFTs) and a pixel electrode that can be either transparent or reflective. The fabrication process is designed to occur at temperatures below 100 degrees Celsius to prevent damage to the plastic substrate. The liquid crystal material used is a commercially available nematic curvilinear aligned phase (NCAP) film. The counter electrode is made from a plastic substrate coated with a transparent conductor, such as indium-doped tin oxide (ITO). This innovative coupling of the active matrix with NCAP allows for high-information content in a fully plastic package, making it suitable for low-cost portable electronics that require rugged displays.
