Claim 12:
13. A method of driving a display device, the method comprising:
sensing a region temperature of a panel region of a display panel;
calculating an accumulated stress value for a block of the display panel based on input image data, wherein the block includes a pixel;
calculating a temperature potential corresponding to the block based on an accumulated stress matrix including the accumulated stress value, an inverse conductance matrix representing a resistance model related to a heat diffusion within the display panel, and a resistance of a heat dissipation plate of the display panel; and
calculating a block temperature based on the region temperature and the temperature potential; and
calculating a temperature potential matrix including the temperature potential by multiplying the inverse conductance matrix by the accumulated stress matrix and the resistance of the heat dissipation plate to obtain the temperature potential.
