Abstract: A light-emitting display device includes first and second sub pixels each of which includes a driving transistor including first and second electrodes and a gate electrode, and being configured to control an electric current flowing from the first electrode to the second electrode according to a data voltage applied to a gate electrode, a light-emitting element connected to the second electrode, and a first capacitor disposed between a first sub supply voltage line to which a first supply voltage is applied and the second electrode. The first sub supply voltage line is disposed to overlap the second electrode. A capacitance of a first capacitor of the first sub pixel versus a capacitance of a first capacitor of the second sub pixel is selectively determined to correspond to an amount of the overlap between the first sub supply voltage line and the second electrode.

Abstract: Systems and methods are provided for a display device that includes a display unit. The display unit includes scan lines and pixels coupled to the scan lines. A timing controller operates in a first mode and a second mode and generates a start signal, based on a vertical synchronization signal provided from the outside. A scan driver generates a scan signal, based on the start signal, and sequentially provides the scan signal to the scan lines. The timing controller generates the start signal immediately after a pulse of the vertical synchronization signal is applied in the first mode, and generates the start signal before a pulse the vertical synchronization signal is applied in the second mode.
