Abstract
A driving method of a display device includes receiving a deterioration amount for a target pixel, calculating a first compensation amount for the target pixel based on the deterioration amount for the target pixel, receiving a gaze angle of a user with respect to the target pixel, selecting one of the first compensation amount and a second compensation amount based on the gaze angle, and calculating an output grayscale for the target pixel by applying the one of the first compensation amount and the second compensation amount to an input grayscale of the target pixel, where the second compensation amount is calculated based on the gaze angle, and the first compensation amount is calculated regardless of the gaze angle.
Claims20
A driving method of a display device comprising:
- receiving a deterioration amount for a target pixel;
- receiving a gaze angle of a user with respect to the target pixel;
- selecting one of a first compensation amount corresponding to the deterioration amount for the target pixel and a second compensation amount corresponding to both the deterioration amount and the gaze angle;
- and
- calculating an output grayscale for the target pixel by adding the one of the first compensation amount and the second compensation amount to an input grayscale of the target pixel, wherein
- the first compensation amount is selected regardless of the gaze angle.
A display device comprising:
- a plurality of pixels which display an image based on output grayscales;
- a gaze angle sensor which senses a gaze angle of a user with respect to a target pixel among the plurality of pixels;
- and
- a deterioration compensator which selects one of a first compensation amount corresponding to a deterioration amount for the target pixel and a second compensation amount corresponding to both the gaze angle or being calculated based on the deterioration amount and the gaze angle, and calculates an output grayscale for the target pixel by adding the one of the first compensation amount and the second compensation amount to an input grayscale of the target pixel, wherein
- the deterioration compensator selects the first compensation amount regardless of the gaze angle.
