摘要：
A display panel control method, a display panel control device, and a display panel. The control method comprises: obtaining a first polarity of a drive voltage of a first pixel column, a second polarity of a drive voltage of a green pixel column, and a third polarity of a drive voltage of a third pixel column (S10); when the second polarity is opposite to the first polarity and the third polarity, determining a voltage compensation value of each of green sub-pixels according to a preset common voltage value and the current common voltage value (S30); and reducing the corresponding first voltage according to each of the voltage compensation values (S40).
