Abstract
A display device includes a pixel emitting light based on input image data, an age data calculator configured to generate age data of a light emitting element included in the pixel in consideration of a power voltage supplied to the pixel, and a compensator configured to output age compensation data by determining a grayscale compensation value corresponding to an input grayscale of the input image data, based on the age data, and applying the grayscale compensation value to the input image data.
Claims21
A display device comprising:
- a pixel emitting light based on input image data;
- an age data calculator configured to generate age data of a light emitting element included in the pixel according to a power voltage supplied to the pixel;
- and
- a compensator configured to output age compensation data by determining a grayscale compensation value corresponding to an input grayscale of the input image data based on the age data and applying the grayscale compensation value to the input image data,
- wherein the age data calculator comprises a degradation calculator calculating degradation data based on the age compensation data, and
- wherein the degradation data is determined based on a luminance acceleration coefficient of the light emitting element and a luminance ratio determined by the age compensation data.
