Patent Images
1. A display device comprising:
- a display panel;
a pixel on the display panel, the pixel comprising at least one light emitting element;
a timing controller configured to receive an image data signal of the pixel and to compensate for a gray value of the image data signal based on the number of light emitting elements of the pixel to generate a compensated image data signal; and
a data driver configured to select a compensation data signal corresponding to the compensated image data signal from the timing controller and to apply the compensation data signal to the pixel.
