US Patent 11450276 Display device and method of controlling pixel circuit

A display device includes a pixel circuit and a control circuit configured to control the pixel circuit. The pixel circuit includes a light-emitting element, and a driving thin-film transistor configured to control the amount of current to the light-emitting element. The control circuit is configured to apply a stress current higher than a maximum current for the light-emitting element to display images to the driving thin-film transistor but not to supply current to the light-emitting element in a period other than light-emitting periods of the light-emitting element to display an image.
