Abstract

A method and a device for driving a display panel, and a display device are provided. The method includes: dividing the display panel into at least two display regions, where each display region corresponds to a timing controller, and the timing controller is configured to control the corresponding display region to display; dividing each display region into multiple detection blocks; detecting whether a defect block exists in each display region; and enabling, when the defect block exists in only one display region, by the timing controller corresponding to the only one display region, a pattern detection function, and enabling, when the defect block exists in each of more than one display region, by the timing controllers corresponding to the more than one display region simultaneously, the pattern detection function.
