Display device and method

A display device comprising:

• a display panel provided with a plurality of pixels;
• and
• a display controller configured to drive the pixels based on a pixel signal for displaying an image in a predetermined gradation to display the image,
• wherein:
• based on a pixel image for displaying a first image in a first gradation, the display controller is configured to drive each of the pixels with first luminance during a first subframe period of a plurality of subframe periods into which a one-frame period for displaying the first image is divided and drive each of the pixels with second luminance during a second subframe period other than the first subframe period of a plurality of subframe periods into which a one-frame period for displaying the first image is divided to display the first image in the first gradation;
• based on a pixel image for displaying a second image in a second gradation, the display controller is configured to drive each of the pixels with third luminance during a third subframe period of a plurality of subframe periods into which a one-frame period for displaying the second image is divided and drive each of the pixels with fourth luminance during a fourth subframe period other than the third subframe period of a plurality of subframe periods into which a one-frame period for displaying the second image is divided to display the first image in the second gradation;
• a luminance difference between the first luminance and the second luminance is equal to or less than a predetermined value;
• a luminance difference between the third luminance and the fourth luminance is equal to or less than the predetermined value;
• and
• a magnitude relationship between the first luminance and the second luminance when the second subframe period is later than the first subframe period is equal to a magnitude relationship between the third luminance and the fourth luminance when the fourth subframe period is later than the third subframe period.

A method executed by a display device comprising a display panel provided with a pixel and a display controller configured to drive the pixel based on a pixel signal for displaying an image in a predetermined gradation to display the image, the method comprising:

• driving the pixel with first luminance during a first subframe period of a plurality of subframe periods into which a one-frame period for displaying the image is divided;
• driving the pixel with second luminance during a second subframe period other than the first subframe period of the plurality of subframe periods, based on the image signal;
• and
• displaying the image in the predetermined gradation corresponding to the first luminance and the second luminance,
• wherein a luminance difference between the first luminance and the second luminance is equal to or less than a predetermined value.

A method executed by a display device comprising a display panel provided with a plurality of pixels and a display controller configured to drive the pixels based on a pixel signal for displaying an image in a predetermined gradation to display the image, the method comprising:

• based on a pixel image for displaying a first image in a first gradation, driving each of the pixels with first luminance during a first subframe period of a plurality of subframe periods into which a one-frame period for displaying the first image is divided;
• based on a pixel image for displaying the first image in the first gradation, driving each of the pixels with second luminance during a second subframe period other than the first subframe period of a plurality of subframe periods into which a one-frame period for displaying the first image is divided;
• displaying the image in the first gradation corresponding to the first luminance and the second luminance;
• based on a pixel image for displaying a second image in a second gradation, driving each of the pixels with third luminance during a third subframe period of a plurality of subframe periods into which a one-frame period for displaying the second image is divided;
• based on a pixel image for displaying the second image in the second gradation, driving each of the pixels with fourth luminance during a fourth subframe period other than the third subframe period of a plurality of subframe periods into which a one-frame for displaying the second is divided;
• and
• displaying the image in the second gradation corresponding to the third luminance and the fourth luminance,
• wherein:
• a luminance difference between the first luminance and the second luminance is equal to or less than a predetermined value;
• a luminance difference between the third luminance and the fourth luminance is equal to or less than the predetermined value;
• and
• a magnitude relationship between the first luminance and the second luminance when the second subframe period is later than the first subframe period is equal to a magnitude relationship between the third luminance and the fourth luminance when the fourth subframe period is later than the third subframe period.
