Abstract

A driving method of a display panel includes: obtaining first initial voltage values respectively corresponding to N sub-pixels on a first data line and second initial voltage values respectively corresponding to the N sub-pixels on a second data line in a first initial picture, and third initial voltage values respectively corresponding to 1st to Mth sub-pixels of the N sub-pixels on the first data line and fourth initial voltage values respectively corresponding to the 1st to Mth sub-pixels on the second data line in a second initial picture following the first initial picture; calculating a voltage compensation value for the Mth sub-pixel based on the corresponding first, second, third, and fourth initial voltage value; calculating a target voltage value for the Mth sub-pixel based on the voltage compensation value; and displaying the second initial picture based on the target voltage value.
