Claim 11:
12. A pixel driving method, applied to the pixel driving circuit according to claim 1, the pixel driving method comprising: a frame period including a scanning phase and a working phase, the scanning phase including a plurality of row scanning periods, wherein
in each of the plurality of row scanning periods, the pixel driving method includes:
writing the first data signal to the driving signal control sub-circuit under the control of the first scanning signal terminal, wherein the first data writing unit is turned on under the control of the first scanning signal terminal, so that the first data signal received at the first data signal terminal is written into the first driving unit; and
writing the second data signal with the set working potential to the driving duration control sub-circuit under the control of the second scanning signal terminal, wherein the second data writing unit is turned on under the control of the second scanning signal terminal, so that the second data signal with the set working potential received at the second data signal terminal is written into the second driving unit; and
the working phase includes:
providing, by the driving signal control sub-circuit, the driving signal to the driving duration control sub-circuit under the control of the enable signal terminal, the driving signal being related to the first data signal and the first voltage signal provided by the first voltage signal terminal, wherein the first control unit is turned on under the control of the enable signal terminal, so that the driving signal is transmitted to the driving duration control sub-circuit; and
receiving, by the driving duration control sub-circuit, the second data signal with the potential varying within the set range under the control of the enable signal terminal; and transmitting, by the driving duration control sub-circuit, the driving signal to the element to be driven, the duration for which the driving signal is transmitted to the element to be driven being related to the second data signal with the set working potential and the second data signal with the potential varying within the set range, wherein the second control unit is turned on under the control of the enable signal terminal, so that the second data signal with the potential varying within the set range is written into the second driving unit, the second driving unit is turned on, the driving signal is transmitted to the first control unit, and the driving signal is transmitted to the element to be driven by the first control unit.
