For example, a Zion pigment that changes color based on a threshold temperature may be applied to the heating display unit 500, and the temperature of the heating display unit 500 changes in response to the heat generated by the heating unit 400. Accordingly, a pattern of a specific color, pattern, letters, and numbers applied to the heating display unit 500 may appear or disappear.
