A Demura system of display and a Demura method thereof are provided. The Demura method includes the following steps. Capturing a display panel of a display by a camera to obtain a plane data of the display. Generating a first baseline data by a processor of a host using the plane data. Masking the first index data by the processor using at least one mask pattern to generate a second baseline data. Superimposing the first baseline data and the second baseline data by the processor to generate a third baseline data. Calculating a coefficient data by the processor using the third baseline data. Setting a lookup table of the display by the processor using the coefficient data to set the display effect of the display.
