Beschreibung
Zusammenfassung:	A display device and a driving method thereof are provided. The display device includes a first light-emitting diode, a first controller, a second light-emitting diode, and a second controller. The first controller has a first current source. The second controller has a second current source, wherein the first current source is coupled to a coupling point of the second light-emitting diode and the second current source. When the first light-emitting diode is normal, the first current source provides a first driving current to drive the first light-emitting diode. When the first light-emitting diode is open, the first current source stops providing the first driving current, and the second current source provides a second driving current to drive the second light-emitting diode.
