Image-storage panels based on field-effect control of conductivity

Abstract

A bsrroct-Using the principle of 6eld-effest conductivity control, a new method of image storage bas been demomtmted. Based 011 this a new type of solid-state image panel bas been developed capable of prodwing a stored 1mn;noSCent image. This m p b y s an -e n t powder layer for generation of the ootpot image and a ZnO powder layer for control and storage porposes In operation the exposed ZnO sorfpce is 6rst uniformly corona charged to a negative potential to reduce L d u c t i v i t y and "erase"
