Abstract
A display device includes: a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area; an image data corrector adjusting a limit grayscale of first image data corresponding to the first pixel area based on a dimming level defining a maximum luminance at which the pixel unit is able to emit light, and correcting the first image data based on the limit grayscale; a data driver supplying data signals to the pixel unit based on the corrected first image data and second image data corresponding to the second pixel area; and a scan driver supplying scan signals to the pixel unit.
Claims20
A display device comprising:
- a pixel unit including first pixels disposed in a first pixel area and second pixels disposed in a second pixel area;
- an image data corrector configured to adjust a limit grayscale of a first image data corresponding to the first pixel area based on a dimming level defining a maximum luminance at which the pixel unit is able to emit light, and correcting the first image data based on the limit grayscale;
- a data driver configured to supply data signals to the pixel unit based on the corrected first image data and second image data corresponding to the second pixel area;
- and
- a scan driver configured to supply scan signals to the pixel unit.
An image data corrector that corrects image data of pixels of a first pixel area of a pixel unit including the first pixel area and a second pixel area, the image data corrector comprising:
- a limit grayscale controller configured to determine a limit grayscale of the image data based on a ratio between a dimming level defining a maximum luminance of the pixel unit and a preset reference luminance of the first pixel area.
