A gamma debugging method includes: according to a duty cycle and gamma data corresponding to a first display brightness level, and a duty cycle corresponding to a second display brightness level, or according to the duty cycle and the gamma data corresponding to the first display brightness level, and gamma data corresponding to the second display brightness level, determining maximum brightness corresponding to an inserted display brightness level and a duty cycle corresponding to the inserted display brightness level; and determining whether a binding-point grayscale at the inserted display brightness level is greater than a preset grayscale threshold, and when the binding-point grayscale at the inserted display brightness level is greater than the preset grayscale threshold, calculating, according to a preset calculation formula, a gamma register value corresponding to the binding-point grayscale at the inserted display brightness level.

Gamma debugging method and apparatus

A display panel and a display device. The display panel includes a first area and a second area, and a plurality of first pixel rows and a plurality of second pixel rows, each of the first pixel row and the second pixel row includes a plurality of pixels. The number of the pixels of each first pixel row is greater than the number of the pixels of each second pixel row. The pixels in the first pixel row are display pixels, and the plurality of pixels in the second pixel row are display pixels and virtual pixels. The display pixel includes a display pixel circuit, the virtual pixel includes a virtual pixel circuit, and the virtual pixel circuit includes a compensation unit.
