Claim 11:
12. The display device of claim 11, wherein the driving controller includes:
a compensator which calculates the compensation value based on first accumulated stress, and to output the output image signal obtain by compensating for the input image signal with the compensation value;
a stress converter which converts the output image signal into current stress in response to an enable signal;
an accumulation stress calculator which outputs second accumulated stress obtained by adding the first accumulated stress and the current stress in response to the enable signal;
a memory which stores the second accumulated stress and to provide the first accumulated stress to the compensator and the accumulation stress calculator; and
an operating time calculator which calculates the accumulated frame weight based on the current operating frequency and to output the enable signal of an active level when the accumulated frame weight is greater than or equal to the update reference value.
