Abstract: A pixel of a display device includes a light-emitting diode and a pixel circuit that provides a current corresponding to a data signal to the light-emitting diode in response to a plurality of scan signals and a light emission control signal. The light emission control signal includes a first section and a second section, the second section includes a light-emission-on section and a light-emission-off section, the light emission control signal has an active level in the light-emission-on section and has an inactive level in each of the first section and the light-emission-off section, and the light-emission-on section and the light-emission-off section of the light emission control signal may vary depending on a light emission ratio of a dimming mode.

Abstract: A display apparatus includes: a foldable display panel to display an image; a gate driver to output a gate signal to the foldable display panel; and a data driver to output a data voltage to the foldable display panel according to a driving current. The driving current is changed according to a display mode that corresponds to a folded state of the foldable display panel.
