1. A method for driving a display panel, comprising a plurality of picture update periods, wherein at least one of the plurality of picture update periods comprises a first data write stage, a second data write stage, and a data retention stage;
at least one of the first data write stage precedes at least one of the second data write stage;
at the first data write stage, a gate scanning signal is provided for and a first data voltage is written to a pixel unit;
at the second data write stage, the gate scanning signal is provided for and a second data voltage is written to the pixel unit, wherein the first data voltage is less than the second data voltage, wherein theoretical brightness corresponding to the first data voltage is greater than theoretical brightness corresponding to the second data voltage.
