The invention discloses a method for evaluating a brightness measurement accuracy of a Demura equipment by generating a noise-added image by adding a random number to an original grayscale image and obtaining a measurement value corresponding to the added random number via the noise-added image displayed by the Demura equipment. The brightness measurement accuracy of the Demura equipment is evaluated based on a correlation between the measured value and the originally added random number to measure a brightness extraction performance of the Demura equipment. The method provided by the invention provides a quantitative and measurable determining method that may better reflect the actual performance of the Demura equipment.
