Title:
DISPLAY DEVICE AND METHOD FOR VISUALIZING COMPUTER GENERATED IMAGE INFORMATION
Document Type and Number:
WIPO Patent Application WO1999060550
Kind Code:
A8
Abstract:
A display for digital/analogous visualization of computer stored and bitmapped still or moving images on or via at least one visualization medium, the display comprising: a matrix including at least two sets of individually addressable electrodes, the electrodes being arrange in rows and columns having crossing points; at least one resistive spacer separating and electrically connecting the sets of electrodes; at least one control unit electrically coupled to said electrodes for applying, multiplexing or scanning first and second control signals to said at least one resistive spacer via said electrodes to obtain a temperature variation in the crossing points of the electrodes; a thermosensitive indication means 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 until the desired temperature is reached; and wherein the resistive spacer consists of a conducting material exhibiting a resistance change at a predefined temperature.
