Classification: CPC G | IPC G

Claim 0:
1. A display device, comprising:
a display panel including a panel region, wherein the panel region includes a block, the block includes a pixel, and a wire is connected to the block;
a temperature sensor sensing a region temperature of the panel region; and
a temperature estimator estimating a temperature of the display panel, the temperature estimator including:
a stress calculator calculating an accumulated stress value corresponding to the block based on input image data;
a temperature potential calculator calculating a temperature potential corresponding to the block based on the accumulated stress value and a resistance of the wire; and
a temperature calculator calculating a block temperature by adding the region temperature and the temperature potential, wherein the temperature of the display panel is estimated based on the block temperature,
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 an accumulated stress matrix including the accumulated stress value.
