Claim 0:
1. A display panel, wherein
the display panel comprises N types of display areas, and the N types of display areas comprise a g-th type display area, an i-th type display area and a j-th type display area;
a light-emitting time period of the g-th type display area, a light-emitting time period of the i-th type display area and a light-emitting time period of the j-th type display area at least partially do not overlap with each other, wherein N is an integer greater than or equal to two, each of g, i and j is an integer greater than zero and less than or equal to N, and g, i and j are not equal to each other;
the display panel comprises M display parts, wherein M is an integer greater than or equal to two;
the M display parts comprise a first display part and a second display part, the first display part comprises at least one i-th type display area, and the second display part comprises at least one i-th type display area;
at least one g-th type display area and one j-th type display area are arranged between the at least one i-th type display area comprised in the first display part and the at least one i-th type display area comprised in the second display part;
the display panel comprises sub-pixels and a pixel driving circuit
the pixel driving circuit comprises:
a pulse width modulation module, configured to output a pulse width setting signal to a first end of a light emitting control module based on a sweep signal;
a driving transistor, configured to output a driving current based on a signal of a gate of the driving transistor and a signal of a first end of the driving transistor; and
the light emitting control module, configured to control the sub-pixels to emit a light in response to the driving current under control of a light emitting control signal, and output the pulse width setting signal to the gate of the driving transistor to control a light emitting time of the driving transistor;

among the N types of display areas, sub-pixels in the same type of display area share the sweep signal and the light emitting control signal;
the N types of display areas comprise an h-th type display area and a k-th type display area, wherein each of h and k is an integer greater than zero and less than or equal to N, and h is not equal to k;
in a same display frame, a start time instant of an effective time period of a sweep signal of a sub-pixel in the h-th type display area is earlier than a start time of an effective time period of a sweep signal of a sub-pixel in the k-th type display area;
each of the M display parts comprises a fourth display part, and the fourth display part comprises at least one h-th type display area and at least one k-th type display area; and
the display panel comprises a power supply voltage input terminal, wherein in the fourth display part, the h-th type display area is arranged on a side of the k-th type display area away from the power supply voltage input terminal.
