Display apparatus and method of compensating deterioration of display panel using the same

A method of compensating deterioration of a display panel, the method comprising:

• storing a luminance reduction rate of a pixel according to a deterioration time;
• calculating a deterioration ratio between a sensing current of one or more pixels in a high deterioration region where the luminance reduction rate is at a first level and a sensing current of one or more pixels in a low deterioration region where the luminance reduction rate is at a second level lower than the first level;
• storing the deterioration ratio and the luminance reduction rate corresponding to the deterioration ratio;
• and
• generating a data signal based on the luminance reduction rate.

A method for compensating a display apparatus, comprising:

• receiving a first sensing current of a pixel in a high deterioration region of a display panel;
• receiving a second sensing current of a pixel in a low deterioration region of the display panel;
• calculating a deterioration ratio based on the first sensing current and the second sensing current;
• determining a luminance reduction rate which corresponds to the deterioration ratio;
• generating a prediction function based on the deterioration ratio and the luminance reduction rate;
• and
• generating a data signal based on the prediction function.
