Title: The Innovative Contributions of Jean N Perbet

Introduction

Jean N Perbet is a notable inventor based in Gif sur Yvette, France. He has made significant contributions to the field of technology, holding a total of eight patents. His work primarily focuses on advancements in image display systems and electro-optic devices.

Latest Patents

One of Perbet's latest patents is a system for the display of images in half tones on a matrix screen. This innovative system enables the creation of half-tones by utilizing control circuits that are not typically designed for this purpose, all while avoiding flicker effects. The system incorporates a memory image with multiple memory planes to store light information for each pixel, allowing for the sequential reading of these planes to produce half-tones. In the simplest case, two planes are used to generate images by extracting bits from each plane in a coordinated manner.

Another significant patent is a device for the modulation of illuminating light in an electro-optic system. This device consists of a liquid crystal screen illuminated by a light source, with an electrically controlled modulating device positioned between the source and the screen. The modulating device adjusts the illuminating intensity based on the electrical signals received, which can include a liquid crystal cell as a key component.
