Abstract

Abstract An arrangement e.g. for image generation and/or reading has first and second light element arranged substantially in two dimensions, control and addressing devices for activation of light or picture elements wherein at least the first light elements are real and form a thin matrix and the second light elements form a denser matrix wherein the position of each first light element at a given time corresponds to the position of a second light element. The addressing devices are spatially arranged or connected to at least each first element, and first as well as second light or picture elements are activated via said control and addressing devices. Activation of the second light or picture elements which at the given time are located at a distance from a first light or picture element which maximally corresponds to the distance between two adjacent first light or picture elements by the respective addressing device is through effective real or fictive displacement of the matrix formed by the first light or picture elements.
