Display panel and pixel circuit thereof

A display panel, comprising:

• a first pixel circuit, comprising:
• a first driving transistor, coupled to a first light emitting device in series, and controlled by a first driving voltage to drive the light emitting device;
• a first switch, coupled between a control end of the first driving transistor and a first source line, and controlled by a first gate signal;
• a second switch, coupled to the first driving transistor and the first light emitting device in series between a power voltage and a reference ground voltage, and controlled by a second gate signal;
• and
• a third switch, coupled between the first light emitting device and a first setting/sensing voltage transmission wire, and controlled by a third gate signal;
• and
• a second pixel circuit, comprising:
• a second driving transistor, coupled to a second light emitting device in series, and controlled by a second driving voltage to drive the light emitting device;
• a fourth switch, coupled between a control end of the second driving transistor and a second source line, and controlled by the first gate signal;
• the second switch, coupled to the second driving transistor and the second light emitting device in series between the power voltage and the reference ground voltage;
• and
• a fifth switch, coupled between the second light emitting device and a second setting/sensing voltage transmission wire, and controlled by the third gate signal,
• wherein a data writing operation and a voltage resetting operation on the control end of the first driving transistor are performed by the same first switch when turned on, and a data writing operation and a voltage resetting operation on the control end of the second driving transistor are performed by the same fourth switch when turned on.
