ABSTRACT:
A thermal image producing device comprising an array of separately addressable thin-film resistors on a substrate with a heat sink at its near face and, so as to render the heat flux flowing through the substrate into the heat sink spatially and temporarily uniform, e.g. to avoid smearing, an array of compensating resistors, each beneath a respective one of the image producing resistors and separated therefrom by an insulating layer. Each compensating resistor is controlled so that, it and its associated image producing resistor together, produce a uniform total heat flux.
