Abstract
A driving method and a driving apparatus of a display panel and a display apparatus are provided. A position information of a current sub-pixel and a driving data for driving the current sub-pixel are obtained. A judgment parameter corresponding to the position information is found from a first parameter look-up table. The driving data whether needs to be compensated is determined. A compensation driving data corresponding to the driving data is found from a second parameter look-up table corresponding to the position information if it needs to be compensated, or else the driving data is directly outputted. Bright and dark stripes or grid phenomenon in a liquid crystal display panel can be effectively eliminated consequently.
