Title: Arthur Berman: Innovator in Liquid Crystal Technology
Introduction
Arthur Berman is a notable inventor based in San Jose, CA (US). He has made significant contributions to the field of liquid crystal technology, holding 2 patents that showcase his innovative approach to stereoscopic displays.
Latest Patents
One of his latest patents is the "Achromatic Liquid Crystal Shutter for Stereoscopic and Other Applications." This inventive shutter features high dynamic range, good transmission, and high speed. It effectively reduces the phenomenon of 'ghosting' that often occurs in conventional plano-stereoscopic CRT displays. The shutter minimizes crosstalk, allowing for comfortable fusion of images. In a preferred embodiment, the shutter system is driven by a carrier-less voltage signal, which simplifies the driving circuit and reduces power consumption. Additionally, a pair of these achromatic shutters can be utilized wirelessly as a selection device for field-sequential stereoscopic electronic display systems.
Another significant patent is the "Method and System Employing a Push-Pull Liquid Crystal Modulator." This system employs a push-pull modulator for stereoscopic image selection. It includes a pair of surface mode liquid crystal cells with orthogonal rub axes and a linear polarizer. The modulator is characterized by high speed, good transmission, and symmetrical dynamic range. It allows for the transmission of field-sequential stereoscopic video images, which can be viewed using passive spectacles with circular polarizing filters.
