GAMMA DEBUGGING METHOD AND GAMMA DEBUGGING DEVICE

摘要

A gamma debugging method and a gamma debugging device. The gamma debugging method is applied to a display panel, the display panel is provided with a first display area (AA1) and a second display area (AA2), and the light transmittance of the first display area (AA1) is greater than that of the second display area (AA2). Said method comprises: selecting, in a second display area, a test area having the same shape and size as a first display area (110); acquiring a first current brightness value of the test area when the test area corresponds to a specified register value under a specified gray scale (120); determining, according to the first current brightness value and a linear relationship between the register value and the brightness of the display panel, a plurality of first target brightness values of the first display area when the first display area corresponds to a plurality of register values under the specified gray scale (130); and performing gamma debugging on the first display area according to the plurality of first target brightness values (140). The gamma debugging method and the gamma debugging device can improve the brightness consistency of the display panel.
