Abstract
The present disclosure relates to a display device and a method of compensating pixel deterioration thereof, capable of determining deterioration of pixels and sensing illuminance of a surrounding environment. The pixel deterioration compensation method compensates for deterioration of the pixels with a target compensation level varied according to illuminance. Accordingly, image quality and lifespan of the pixels is improved by mitigating or preventing acceleration of deterioration of the pixels without deteriorating image quality such as afterimages.
Claims18
A display device comprising:
- a display panel in which a plurality of scan lines and a plurality of data lines intersecting with one another and a plurality of pixels are arranged;
- a deterioration determination unit configured to determine deterioration of the plurality of pixels;
- a sensing unit configured to sense illuminance of surrounding environment of the display panel;
- and
- a compensation block configured to receive a deterioration sensing value or a deterioration predicted value from the deterioration determination unit and receive illuminance data from the sensing unit to compensate for the deterioration of the pixels with a target compensation level varied according to the illuminance.
A method for compensating pixel deterioration of a display device including a display panel in which a plurality of scan lines and a plurality of data lines intersect with one another and a plurality of pixels are arranged, the method comprising:
- determining deterioration of the plurality of pixels;
- sensing the illuminance of surrounding environment of the display panel;
- and
- compensating for the deterioration of the plurality of pixels with a target compensation level varied according to the illuminance.
