Abstract: Thermochromic liquid crystal is one of the crystals that can reflect the temperatures by different colors.The special color shown by the thermochromic liquid crystal in its scope of the working temperature corresponds to a certain temperature.This paper describes the main structure of the thermochromic liquid crystal and the principle of the temperature measurement.It introduces the method of collecting the temperature images of the thermochromic liquid crystal and demarcating the hue of the thermochromic liquid crystal and the temperature.The correlation of the hue and the temperature is obtained.

Key words: thermochromic liquid crystal； temperature； hue； correlation；
