Abstract: A display device includes a display panel including a plurality of pixels, each of the plurality of pixels having a light-emitting element that emits light based on current that corresponds to a data voltage, and a timing controller configured to set level of a supply voltage of the display panel for displaying input image data, set an automatic current limit (ACL) value of the display panel based on the level of the supply voltage, and adjust a luminance gain of the input image data based on the ACL value to generate the data voltage.
