The invention provides a Mura phenomenon compensation method. A brightness correction coefficient formula is utilized for calculating the brightness correction coefficient of each position on an LCD display panel, thereby correcting brightness data of the LDC display panel at different gray scales according to the calculated brightness correction coefficient, wherein the brightness data are acquired through photographing by a camera, and furthermore obtaining the corrected brightness data. Furthermore Mura compensation data are acquired according to the corrected brightness data. Finally Mura compensation is performed on the LCD display panel according to the Mura compensation data. Therefore the Mura phenomenon compensation method has functions of preventing an adverse effect on Mura compensation effect caused by photographing angle of the camera, and improving product quality of the LCD display panel.
