Claim 19:
20. A method for driving a display substrate, comprising: a power-on period and a power-off period;
wherein the power-on period includes a plurality of display cycles; in each of the plurality of display cycles,
along an extension direction of data lines of the display substrate, writing first scanning signals into a plurality of gate lines of the display substrate one by one, wherein effective level periods of the first scanning signals input into adjacent gate lines partially overlap;
in two adjacent sub-pixel rows of the display substrate, when the first scanning signal written by the gate line corresponding to a preceding sub-pixel row is at an effective level and the first scanning signal written by the gate line corresponding to a subsequent sub-pixel row is at the effective level, turning on data writing transistors included in various sub-pixel driving circuits in the preceding sub-pixel row, to transmit a data signal written by the corresponding data line to which each of the data writing transistors is coupled, to a gate electrode of a corresponding driving transistor to which the each of the data writing transistors is coupled; meanwhile, turning on sensing transistors included in various sub-pixel driving circuits in the preceding sub-pixel row, to transmit a reset signal written by the corresponding sending signal line to which each of the sensing transistors is coupled, to a first electrode of corresponding driving transistor to which the each of the sensing transistors is coupled;
in the two adjacent sub-pixel rows of the display substrate, when the first scanning signal written by the gate line corresponding to the preceding sub-pixel row is at an ineffective level and the first scanning signal written by the gate line corresponding to the subsequent sub-pixel row is at the effective level, turning on the driving transistors and the sensing transistors in the preceding sub-pixel row to charge the corresponding sending signal line to which each of the sensing transistors is coupled;
in the two adjacent sub-pixel rows of the display substrate, when the first scanning signal written by the gate line corresponding to the preceding sub-pixel row is at the ineffective level and the first scanning signal written by the gate line corresponding to the subsequent sub-pixel row is at the ineffective level, turning on the driving transistors in the preceding sub-pixel row, turning off the sensing transistors in the preceding sub-pixel row, light-emitting units in the preceding sub-pixel row emitting light.
