ABSTRACT:
A solid state circuit which has a plurality of integrated circuit elements, each having at least a pair of connecting terminals. The operability of the individual elements is determined by providing an arrangement including an insulating layer on the solid state circuit, this insulating layer having arranged on it the pairs of terminals of the individual elements with the insulating layer insulating all of the terminals from each other. At least one further layer is arranged on the insulating layer and covers at least the respective pairs of terminals of the elements. This further layer has, at least in the region where it covers respective pairs of element terminals, optical characteristics which are selectively variable in dependence on the potential difference between the pairs of terminals of each respective element. The arrangement may be used as a picture producer, converter or amplifier.
