Claim 9:
10. A temperature estimator, comprising:
a stress calculator calculating an accumulated stress value corresponding to a block of a display panel based on input image data, the block including a pixel;
a temperature potential calculator calculating a temperature potential corresponding to the block based on the accumulated stress value and a resistance of a wire connected to the block; and
a temperature calculator calculating a block temperature by adding a region temperature of a panel region of the display panel and the temperature potential,
wherein the display panel further includes a rear surface and a heat dissipation plate disposed on the rear surface, and
wherein the temperature potential calculator calculates 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 by an accumulated stress matrix including the accumulated stress value.
