Classification: CPC G | IPC G

Claim 19:
20. An operating method of a display device, the method comprising:
receiving an input image signal and a current operating frequency;
outputting an output image signal based on the input image signal and first accumulated stress;
calculating a first accumulated frame weight based on the current operating frequency;
when the first accumulated frame weight is greater than or equal to an update reference value, outputting an enable signal of an active level;
when the enable signal is at the active level, converting the output image signal into current stress; and
when the enable signal is at the active level, calculating second accumulated stress based on the first accumulated stress and the current stress and storing the second accumulated stress in a memory,
wherein the second accumulated stress stored in the memory is provided as the first accumulated stress.
