1. A gamma debugging method, applied to a display panel, wherein the display panel comprises a first display region and a second display region, and the second display region has a pixel density lower than a pixel density of the first display region, and the gamma debugging method comprises:
obtaining a predetermined gamma data set of the first display region;
selecting a test display region in the first display region, taking part of sub-pixels in the test display region as test sub-pixels, and performing gamma debugging on the test sub-pixels to obtain a first gamma data set by causing the test sub-pixels to light up and sub-pixels in the test display region other than the test sub-pixels not to emit light and adjusting analog data voltages provided to the test sub-pixels, where the test sub-pixels positionally correspond to sub-pixels in the second display region;
controlling all the sub-pixels in the test display region and all sub-pixels in the second display region to emit light, and detecting a target luminance and a target chrominance of the test display region that correspond to a corresponding grayscale;
performing gamma debugging on the second display region, such that at the corresponding grayscale, a luminance of the second display region is the target luminance, and a chrominance of the second display region is the target chrominance, and accordingly obtaining a second gamma data set; and
obtaining, based on the second gamma data set, the first gamma data set and the predetermined gamma data set, a third gamma data set applied to the second display region by obtaining a difference gamma data set based on the second gamma data set, the first gamma data set and the predetermined gamma data set.
