Claim 0:
1. A driving controller comprising:
a compensator which receives an input image signal, calculates a compensation value based on first accumulated stress, and outputs an output image signal 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 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 provides the first accumulated stress to the compensator and the accumulation stress calculator; and
an operating time calculator which receives a current operating frequency and outputs the enable signal of an active level based on the current operating frequency.
