1. A display panel, comprising:
a display region;
a non-display region at least partially surrounding the display region;
a plurality of sub-pixels, wherein the plurality of sub-pixels is located in the display region, each sub-pixel of the plurality of sub-pixels comprises a pixel circuit and a light-emitting device, and each pixel circuit comprises:
a drive module configured to generate a drive current according to a voltage of a control terminal of the drive module to drive the light-emitting device to emit light;
an initialization module configured to simultaneously write an initialization voltage into both the control terminal of the drive module and an anode of the light-emitting device;
a data write module configured to transmit a data voltage to the drive module; and
a storage module configured to store the voltage of the control terminal of the drive module; and
at least one reused signal line; and,
for each sub-pixel of the plurality of sub-pixels, an input terminal of the initialization module in the pixel circuit and a cathode of the light-emitting device are electrically connected to one reused signal line of the at least one reused signal line; and each reused signal line of the at least one reused signal line is configured to;
in an initialization stage, provide the initialization voltage for the initialization module connected to the respective reused signal line; and
in a light emission stage, provide a cathode voltage for the cathode of the light-emitting device connected to the respective reused signal line, wherein the pixel circuit of each sub-pixel of the plurality of sub-pixels further comprises at least one light emission control module, the at least one light emission control module further comprises a first light emission control transistor, a second light emission control transistor, and a third light emission control transistor, a first electrode of the third light emission control transistor is connected to the cathode of the light-emitting device, a second electrode of the third light emission control transistor is connected to the at least one reused signal line, and a gate of the third light emission control transistor is connected to a light emission control signal line.
