Abstract
This application discloses a drive method and drive circuit of a display panel. The drive method includes: dividing the display panel into a plurality of charging areas in advance according to distances from a data driver chip, determining a unique code for each charging area, and pre-storing corresponding information of the charging areas and the digital codes into a timing control chip; detecting a charging area where a pixel to be charged is located, and outputting, by the timing control chip, a corresponding code according to the charging area; and outputting, by the timing control chip, the code to a gamma chip, receiving, by the gamma chip, the code, and outputting a gamma voltage corresponding to the code according to the code to drive charging work of the charging area corresponding to the code.
