Abstract
Electro-optical instrument where the electromagnetic radiation absorption characteristics can be selectively altered by means of a suitably controlled electric field. The reproduction region (A) consists of a transparent front panel (1), made from glass or a suitable plastic material. The inside surface (2) of the front panel has an X-Y system of discrete regions (3) of an electrochrome (EC) material. This is used as a light modulating material. There is a counter electrode, and an ion conducting material, which is in contact with the electrochrome material and counter electrode. The reproduction unit is addressed by modules which incorporate direct current pulse sources and elements to maintain the direct current during the period after the addressing.
