Abstract
A flat panel display device includes an electron emission substrate; an image forming substrate spaced apart from the electron emission substrate; a spacer disposed between the electron emission substrate and the image forming substrate; a detector coupled to the electron emission substrate for detecting a temperature value of the flat panel display device; a temperature controlling part for receiving the receiving the temperature value and for controlling a temperature of the electron emission substrate based on the received temperature value; and a cooler for cooling the flat panel display device to be at the temperature controlled by the temperature controlling part.
