Abstract
Provided are a display panel, a driving method thereof and a display apparatus. The display panel includes bias signal lines and pixel circuits. A pixel circuit includes a drive module and a bias module. The bias module is connected between a first terminal of the drive module and a bias signal line. A display region of the display panel includes a first display region and a second display region. The bias signal lines include a first bias signal line and a second bias signal line. Bias modules in the first display region are connected to the first bias signal line. Bias modules in the second display region are connected to the second bias signal line. In at least part of turning-on stages of bias modules, a voltage transmitted by the first bias signal line is different from a voltage transmitted by the second bias signal line.
