Electrochromic contrast plate
First Claim
1. Electrochromic contrast plate (6), consisting of a pair of transparent glass or plastic sheets (5, 9), which are provided on one side each with an electroconductive, transparent coating (7, 8), and which are joined together at the sides of their conductive coating via a sealing ring, and in which the volume formed by the two sheets and the sealing ring is filled with an electrochromic medium (10), characterized in that the electrochromic medium (10) is a liquid, a gel or a polymer.

Abstract
The invention relates to an electrochromic contrast plate which is either arranged as a discrete unit in front of the screen or is connected to the outer surface of the screen through a common sheet, consisting of a pair of transparent glass or plastic sheets which are provided, on one side each, with an electroconductive, transparent coating, and which are joined together on the sides of their conductive coating via a sealing ring, and in which the volume formed by the two sheets and the sealing ring is filled with an electrochromic medium, characterized in that the electrochromic medium is a liquid, a gel or a polymer. The invention furthermore relates to an electrochromic contrast plate with integrated touch screen which has a larger base area than the area of the screen, and, at at least one of the faces of the outer sheet (outer plate) of the electrochromic contrast plate, a radiation source is arranged whose light enters the outer plate and illuminates it, and, at the inner sheet (carrier plate), in the region which projects beyond the screen area, a photodetector is mounted in whose photosensitive solid-angle region part or all of the carrier plate is located, if it projects beyond the screen area. The invention furthermore relates to electrochromic side-chain oligomers or polymers which can be used as electrochromic media.
