Abstract:
A thermochromatic device includes an insulating substrate, a color element, a heating element, a first electrode, and a second electrode. The color element is located on the insulating substrate and includes a color-changeable material. A phase of the color-changeable material is changeable between a crystalline state and an amorphous state. A temperature phase change of the color-changeable material is above 40° C. A first reflectivity of the color-changeable material at the crystalline state and a second reflectivity of the color-changeable material the amorphous state are different. The heating element is located adjacent to the color element and includes a carbon nanotube structure. The first electrode and the second electrode are electrically connected to the heating element. A thermochromatic display apparatus using the thermochromatic device is also related.
