1. A display device, comprising:
a first pixel, comprising:
a first sub-pixel, comprising a first emission control switch and a first light-emitting unit, wherein the first emission control switch is electrically connected to the first light-emitting unit;
a second sub-pixel, comprising a second emission control switch and a second light-emitting unit, wherein the second emission control switch is electrically connected to the second light-emitting unit; and
a third sub-pixel, comprising a third emission control switch and a third light-emitting unit, wherein the third emission control switch is electrically connected to the third light-emitting unit;
a first emission signal line, electrically connected to a gate electrode of the first emission control switch and a gate electrode of the second emission control switch; and
a second emission signal line, electrically connected to a gate electrode of the third emission control switch,
wherein the first emission signal line is configured to provide a first emission signal to the gate electrodes of the first emission control switch and the second emission control switch to turn-on the first emission control switch and the second emission control switch, so that the first emission control switch and the second emission control switch provide a first driving current and a second driving current to drive the first light-emitting unit and the second light-emitting unit, wherein the second emission signal line is configured to provide a second emission signal to the gate electrode of the third emission control switch to turn-on the third emission control switch, so that the third emission control switch provides a third driving current to drive the third light-emitting unit, wherein a duty ratio of the first emission signal is greater than a duty ratio of the second emission signal.
