Method for compensating mura of display device and mura compensation system

摘要

A mura compensation method for a display device in which a data driver and a scan driver disposed at a first side of a pixel unit, includes capturing an image of the pixel unit based on a predetermined first sample gray level; calculating mum luminance of diagonal mura corresponding to the first sample gray level by sharpening the diagonal mura based on light components of the captured image for a first sample area including the diagonal mura; calculating target luminance based on the mura luminance and a luminance distribution of the imaged first sample area; and calculating a first compensation value corresponding to the first sample gray level and a pixel corresponding to the diagonal mura in the first sample area by using the first sample gray level, the mura luminance, and the target luminance.
