Abstract
A Mura correction system which detects and corrects Mura in a detection image obtained by photographing a display panel. The Mura correction system detects a Mura block by checking, based on a brightness value, detection images obtained by photographing test images displayed on a display panel, generates coefficient values of coefficients of a Mura correction equation, and generates Mura correction data including a position value of the Mura block and the coefficient values of the coefficients of the Mura correction equation.
