Display device

A driving method for a display apparatus, the display apparatus including

• a display unit that includes a display area including display elements arranged in a two-dimensional matrix and is configured to display an image in the display area based on a video signal, the display elements each including a current-drive-type light-emitting unit, and
• a correction signal generation unit configured to generate a correction signal that accelerates a change with time for a display element having a small change with time and performs one of a slowdown and a stop of the change with time for a display element having a large change with time, based on one of a value of the video signal for each of the display elements and a value of the video signal for each predetermined area in the display unit and based on time-varying characteristics of a luminance of each of the display elements,
• the driving method comprising:
• displaying, by the display apparatus, when the display apparatus is not used after a normal image is displayed based on the video signal, a corrected image based on the correction signal to equalize a degree of the change with time of each of the display elements.

A display apparatus, comprising:

• a display unit that includes a display area including display elements arranged in a two-dimensional matrix and is configured to display an image in the display area based on a display signal, the display elements each including a current-drive-type light-emitting unit, the display signal being a video signal when a normal image is displayed and being a correction signal when a correction image is displayed to equalize a degree of luminance deterioration of the display elements;
• and
• a correction signal generation unit configured to:
• determine a cumulative luminance deterioration amount for each of the display elements based on values of the display signal for the respective display element and on one or more corresponding luminance deterioration functions;
• generate the correction signal based on the cumulative deterioration amounts such that display of the correction image accelerates luminance deterioration for those display elements having a small cumulative luminance deterioration amount and slows down or stops luminance deterioration for those display elements having a large cumulative luminance deterioration amount.

• and
• a correction signal generation unit configured to:
• update a cumulative luminance deterioration value for each of the display elements when a value of the display signal is input to the respective display element by:
• determining an incremental luminance deterioration value for the respective display element based on the display signal and on one or more corresponding luminance deterioration functions;
• and
• incrementing the cumulative luminance deterioration value for the respective display element by the incremental luminance deterioration value for the respective display element;
• and
• generate the correction signal based on the cumulative deterioration values such that display of the correction image accelerates luminance deterioration for those display elements having a small cumulative luminance deterioration value and slows down or stops luminance deterioration for those display elements having a large cumulative luminance deterioration value.

An electronic apparatus comprising:

• a display unit including a display area;
• and
• a battery unit,
• wherein the display area is configured to display a normal image and a correction image, and
• wherein the correction image is displayed during charging the battery unit.
