Abstract
In this paper, we describe a powerful solution for efficient LED wall calibration through the use of a quality 2D-luminance meter : the MURATest and a dedicated applicative software. The intended calibration allows adjusting individually the intensity of each LED so as to obtain a good uniformity on the module. Furthermore the intensity of each module can be adjusted one to the others so as to obtain a good uniformity on a complete display and maintain it even after module exchange for display maintenance needs.
