Abstract
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.
