1. A display apparatus, comprising:
a display panel that includes a pixel;
a driving controller that
generates an age compensation value using both of a sensed age generated based on sensing data received from a light emitting element of the pixel and an accumulated age generated based on compensated grayscale values of input image data,
generates a final age based on the age compensation value and the accumulated age, and
generates the compensated grayscale values of the input image data based on the final age and input grayscale values of the input image data, wherein
a data signal is generated; and
a data driver that converts the data signal to a data voltage and outputs the data voltage to the display panel,
wherein a first cycle that generates the sensed age differs from a second cycle that generates the accumulated age.
