Abstract
A driving method and a driving apparatus of a display panel are provided. The driving method includes: detecting voltage change delay times of data lines in a fan-out area; controlling data output signals of the data lines according to the voltage change delay times; and adjusting a scan line driving voltage signal according to the data output signal and thereby making effective charging times of pixels driven by different data lines be consistent.
