Case for portable terminal using color liquid crystal

Image Number 4 for United States Patent #7236364.

A case for a portable terminal using a color liquid crystal uses a Peltier device to vary the color of the case by means of electrical heating and cooling the interior of the case. The case includes a temperature control apparatus for emitting electrical heat, when an electrical current is applied thereto, and simultaneously cooling the opposite side; a liquid crystal application agent positioned on the upper portion of the temperature control apparatus and adapted to vary the color by means of the electrical heat; and a cooling unit positioned opposite to an upper portion of the temperature control apparatus to cool heat-generating devices inside the terminal.
