Abstract

The present application provides a grayscale calibrating method for a display panel and a display device. The grayscale calibrating method for a display panel includes obtaining a screen image to be displayed of the display panel, and determining whether the screen image to be displayed exists in an abnormal display region; when the screen image to be displayed exits in the abnormal display region, increasing the grayscale of each of the first sub-pixels located in the first display region by changing a white balance component to improve the display effect of the abnormal display region.
