<p>The screen has a base plate (1) and a flexible plastic film (3) provided with respective electrically conducting covers (2, 4), where one of the covers is divided into cover fields (8) that reach to edge of the film and/or plate. An electronic control and evaluation device determines a position at which the covers are brought in electrical contact with one another. Operating fields (7) are operated independent of each other by fingers to produce different signals such that respective operating positions on the individual operating fields are determined when the operating fields are operated.</p> |
