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.

Abstract: A Mura correction driver which corrects Mura detected in a detection image obtained by photographing a display panel. The Mura correction driver uses Mura correction data including a position value of a Mura block for a display panel and coefficient values for the Mura block, and corrects display data corresponding to the position value of the Mura block, by using a Mura correction equation to which the coefficient values of the Mura block are applied.

Abstract: A Mura correction system which performs correction of a Mura pixel in a detection image obtained by photographing a display panel. The Mura correction system may detect an individual Mura pixel and realize correction on the detected one Mura pixel, and may realize block-based correction on Mura pixels of some region of a Mura block.
