Solid state circuit

An indicating device for representing information, comprising a solid state circuit which has a plurality of integrated circuit elements each having at least a pair of connecting terminals, and means for activating each of said elements, said means comprising

• (a) means forming a first, insulating layer on said solid state circuit and having arranged on it the pairs of terminals of said elements, said insulating layer insulating all of the terminals from each other;
• and
• (b) means forming at least one second layer arranged on said insulating layer and covering at least the respective pairs of terminals of said elements, said second layer having, at least in the regions where it covers respective pairs of element terminals, optical characteristics which are selectively variable in dependence on the potential difference between the pair of terminals of each respective element.

A picture converter comprising a solid state circuit which has a plurality of light-sensitive integrated circuit elements each having at least a pair of connecting terminals, and means for providing an indication of the impingement of light on each of said elements, said means comprising

• (a) means forming a first, insulating layer on said solid state circuit and having arranged on it the pairs of terminals of said elements, said insulating layer insulating all of the terminals from each other;
• and
• (b) means forming at least one second layer arranged on said insulating layer and covering at least the respective pair of terminals of said elements, said second layer having, at least in the regions where it covers respective pairs of element terminals, optical characteristics which are selectively variable in dependence on the potential difference between the pair of terminals of each respective element.

A picture amplifier comprising a solid state circuit which has a plurality of light-sensitive integrated circuit elements each having at least a pair of connecting terminals, and means for providing an indication of the impingement of light on each of said elements, said means comprising

• (a) means forming a first, insulating layer on said solid state circuit and having arranged on it the pairs of terminals of said elements, said insulating layer insulating all of the terminals from each other;
• and
• (b) means forming at least one second layer arranged on said insulating layer and covering at least the respective pairs of terminals of said elements, said second layer having, at least in the regions where it covers respective pairs of element terminals, optical characteristics which are selectively variable in dependence on the potential difference between the pair of terminals of each respective element.
