Claim 6:
7. A display device, comprising:
a display panel including a display area, a peripheral area partially surrounding the display area, a rear surface, and a panel region;
a heat dissipation plate disposed on the rear surface of the display panel;
a temperature sensor disposed on the heat dissipation plate or the peripheral area and sensing a region temperature of the panel region of the display panel; and
a temperature estimator estimating a temperature of the display panel based on a temperature potential corresponding to input image data and the region temperature, wherein the temperature potential is added to the region temperature and wherein the temperature potential is determined based on a resistance of the heat dissipation plate,
the temperature estimator including a temperature potential calculator calculating a temperature potential matrix including the temperature potential by multiplying an inverse conductance matrix representing a resistance model related to heat diffusion within the display panel by a resistance of the heat dissipation plate and an accumulated stress matrix including an accumulated stress value.
