Abstract
A method for Gamma debugging. The method for Gamma debugging is applicable to a display panel including a first display area and a second display area. A light transmittance of the first display area is greater than that of the second display area. The method includes: selecting, in the second display area, a test area having a same shape and size as the first display area; obtaining a first present brightness value when the test area corresponds to a specified register value under a specified grayscale; determining a plurality of first target brightness values when the first display area corresponds to a plurality of register values under the specified grayscale, according to the first present brightness value and a linear relationship between register values and brightness of the display panel; and performing Gamma debugging on the first display area according to the first target brightness values.
