Enclosed migration imaging system
Abstract
Abstract A DISPLAY SYSTEM WHICH RESPONDS TO A LIGHT IMAGE TO FORM A VIEWABLE IMAGE. THE SYSTEM IS SEALED AND IS FILLED WITH A FLUID CARRYING A DILUTE SUSPENSION OF ELECTRICALLY PHOTOSENSITIVE PARTICLES BETWEEN TWO CONDUCTIVE PLATES. IF AN IMAGE IS FOCUSED ONTO THE SPACE BETWEEN THE PLATES AND A VOLTAGE ESTABLISHED THEREBETWEEN, THE PARTICLES IN CONTACT WITH THE INNER SURFACE OF THE CONDUCTIVE PLATE WILL MIGRATE FROM LIGHT STRUCK AREAS OF THE PLATES. AFTER THE FLUID HAS BEEN CIRCULATED FOR AN APPROPIATE TIME AFTER IMAGING, THE FLUID CIRCULATION IS DIRECTED THROUGH A FILTER, WHICH REPLACES THE FLUID BETWEEN THE PLATES WITH FLUID HAVING THE UNDEPOSITED PARTICLES REMOVED. VARIOUS PROVISIONS FOR VIEWING THE IMAGES FORMED WITHIN THE DISPLAY SYSTEM ARE DESCRIBED.
