US Patent 7933058 - CNT heater for thermochromic display

http://www.freepatentsonline.com/7933058.html

Thermochromic materials have a color  sensitivity to heat and have been proposed as a means to develop paper thin and flexible electronic displays. This patent from Hon Hai Precision (Foxconn) teaches a way to use carbon nanotube heaters to achieve this type of electronic display. Claim 1 reads:

1. A thermochromic component, comprising:

a thermochromic module capable of changing colors under changing temperature conditions;

a heater thermally coupled with the thermochromic module and comprising a carbon nanotube structure, the carbon nanotube structure being capable of applying heat to the thermochromic module; and

two electrodes electrically connected to the heater and configured to apply a voltage to the heater.
