Abstract: A display panel including a first current source and a first pixel unit is provided. The first pixel unit includes a first switch and a first light-emitting diode. The first switch is coupled to the first current source and receives a first scan signal. When the first scan signal is enabled, the first switch is turned on and receives a first current provided by the first current source. The first light-emitting diode is coupled to the first switch. When the first switch is turned on, the first current passes through the first light-emitting diode to turn on the first light-emitting diode.
