ABSTRACT:
A multilayered thermochromic display system is provided, wherein a thermochromic substance is applied to inert films in stacked layers with a non-invasive barrier between each layer of thermochromic substance. The thermochromic substance in each layer responds in a different temperature range so that as the temperature changes, the display exhibits repeated sequences of colors. The use of multiple layers with different temperature sensitivities enables the use of the displays over a broad range of temperatures.
