A display for digital/analogous visualization of computer stored and bitmapped, in the form of still or moving patterns, (e.g., text or images) or the like, on or by way of at least one visualization medium. The display consists of one matrix including at least two sets of electrodes, wherein the electrodes cross each other. The electrodes are distanced from each other by at least one resistive and/or inductive spacer, and are connected to at least one control device for multiplexing, scanning or pulsating the control signals. The electrodes are individually addressable in accordance to electric signals from a control unit and are provided so that when selected electrodes in both sets of the electrodes are energized, a temperature change (heat) is conducted towards the medium. The medium includes a thermosensistive indicator (e.g.) a layer, or a body. The surface/surfaces in the display are provided to transform the temperature change to visible dots.

[ What is claimed is:] [1.]1. A display for digital/analog visualization of computer stored and bitmapped still or moving images on or via at least one visualization medium, the display comprising:a matrix comprising at least two sets of individually addressable electrodes, the electrodes being arranged in rows and columns with overlapping regions defined by the overlapping parts of a row and a column;a set of at least two resistive spacers positioned in the overlapping regions and electrically connecting the sets of electrodes;at least one control unit electrically coupled to said electrodes for applying, multiplexing, scanning or pulsating first and second control signals to the set of at least two resistive spacers via said electrodes to obtain a temperature variation in the overlapping regions; anda thermosensitive material covering the electrodes and transforming the temperature variation to a visible dot,wherein:the control unit applies the first control signals comprising a plurality of low voltage and short duration pulses of electric current until the desired temperature is reached; andthe control unit intermittently applies the second control signals to the electrodes with an amount of energy per time unit to maintain the desired temperature, so that the visible dot remains until a next update of the display, wherein the second control signals are spaced apart further in time compared to the first control signals.
