Claim 17:
18. The display panel according to claim 16, further comprising: n rows of pixel circuits;
for a light emission control module in any one of pixel circuits, the light emission control module is configured to be turned on at the light emission stage under a control of a first light emission control signal corresponding to an i-th row where a pixel circuit to which the light emission control module belongs is located and under a control of a second light emission control signal corresponding to the i-th row where the pixel circuit to which the light emission control module belongs is located so that the driving branch is turned on;
wherein the first light emission control signal corresponding to the i-th row where the pixel circuit is located is a light emission control signal output from a shift register at an i-th stage in the first light emission control driving circuit, and the second light emission control signal corresponding to the i-th row where the pixel circuit is located is a light emission control signal output from a shift register at an i-th stage in the second light emission control driving circuit, wherein a starting point of a first extinguishing signal of the first light emission control signal within one frame is earlier than a starting point of an extinguishing signal of the second light emission control signal, and the period of the initialization stage within one frame is equal to a period difference between the starting point of the first extinguishing signal of the first light emission control signal and the starting point of the extinguishing signal of the second light emission control signal;
wherein the third initialization unit comprises a double-gate transistor, a first gate of the double-gate transistor serves as the control terminal of the third initialization unit, a second gate of the double-gate transistor serves as an additional control terminal of the third initialization unit, and the additional control terminal accesses the first light emission control signal; and
within one frame, the first light emission control signal comprises a plurality of extinguishing signals, and the second light emission control signal comprises one extinguishing signal.
