Abstract
A display device according to an exemplary embodiment includes a display panel that includes a plurality of pixels, and an image shifter that corrects an image corresponding to input image data to be shifted based on age data with respect to the plurality of pixels and an input grayscale of input image data and outputs corrected image data, wherein a shift range of the image is reduced when an age value of the age data exceeds a threshold value.
Claims18
A display device comprising:
- a display panel that includes a plurality of pixels;
- and
- an image shifter configured to correct an image corresponding to input image data to be shifted based on age data with respect to the plurality of pixels and an input grayscale of input image data and outputs corrected image data,
- wherein the image shifter is further configured to increase a shift range of the image when an age value of the age data increases to an increased age value and the increased age value is below a threshold value, and the image shifter is further configured to reduce the shift range of the image when the age value of the age data exceeds the threshold value.

A method for displaying an image of a display device, comprising:
- calculating degradation weight values with respect to a plurality of pixels included in a display panel based on input image data, and calculating degradation data of one frame;
- generating age data by accumulating the degradation data;
- and
- generating corrected image data by shifting an image corresponding to the input image data based on the age data and an input grayscale of the input image data,
- wherein a shift range of the image is reduced when an age value of the age data exceeds a threshold value, and
- wherein the shift range of the image is increased as the age value of the age data increases to an increased age value, wherein the increased age value is below the threshold value.

A display device comprising:
- a display panel that includes a plurality of pixels;
- and
- an image sticking compensator configured to determine a grayscale compensation value corresponding to age data with respect to the plurality of pixels and input image data, and to output age compensation data by applying the grayscale compensation value to the input image data,
- wherein the image sticking compensator is further configured to divide the display panel into a plurality of blocks, set block weight values with respect to the respective blocks, apply the block weight value to the age data, and determine the grayscale compensation value based on the block weight value-applied age data, and
- wherein the image sticking compensator is further configured to reduce block weight values of a block and the neighboring blocks of the block when an average of age values of pixels included in the block along the plurality of blocks exceeds the threshold value.
