Claim 1:
2. The display panel according to claim 1, wherein:
a length of a channel region of the first driving portion is L1, a length of a channel region of the second driving portion is L2, and a length of a channel region of the third driving portion is L3;
L3/(L1+L2)≥ΔVs1d2/(ΔVgd2+V0)−1 and 0≤V0≤ΔVs1g×½; or
L2/(L1+L3)≥ΔVs1d2/(ΔVs1g+V0)−1 and 0≤V0≤ΔVgd2×½;
wherein ΔVs1d2=|Vs1−Vd2|, ΔVs1g=|Vs1−Vg|, and ΔVgd2=|Vg−Vd2|, in a light-emitting stage of the light-emitting element, Vs1 is a voltage of the first source of the driving transistor, Vd2 is a voltage of the second drain of the driving transistor, and Vg is a voltage of the gate of the driving transistor.
