Drive compensation method and system of a display panel, and display device

A drive compensation system of a display panel, wherein the display panel comprises:

• a plurality of pixel units sequentially arranged in a row direction and a column direction respectively;
• and a plurality of signal lines extending in the row direction and the column direction respectively;
• wherein the plurality of pixel units comprise first pixel units sequentially arranged in the row direction, and the plurality of signal lines comprise first signal lines extending in the column direction;
• and
• wherein the drive compensation system comprises:
• a variation curve determination module configured to determine at least one of an impedance and capacitive reactance variation curve of one of the first signal lines in the column direction and a charge rate variation curve of the first pixel units in the row direction;
• a compensation coefficient determination module configured to determine a compensation coefficients for a respective pixel unit of the plurality of pixel units in the column direction and/or the row direction according to the impedance and capacitive reactance variation curve of the one first signal line in the column direction and/or the charge rate variation curve of the first pixel units in the row direction;
• and
• a drive compensation module configured to compensate the compensation coefficient for the respective pixel unit in the column direction and/or the row direction to a drive signal of the respective pixel unit to drive the respective pixel unit.
