TrueMura License for TrueTest Software

TrueMura™ License for TrueTest™ Software – the TrueMura license was developed to perform automated visual inspection of displays to accurately identify JND—artifacts just noticeable by a human observer. TrueMura measures display mura (areas of non-uniformity) and defect severity using algorithms that can ignore mura that is imperceptible to human observers and identify various types of mura that can be passed and failed based on evaluation criteria. Efficiently perform image-based measurements for luminance, chromaticity, and add specific tests to evaluate over 15 types of display mura such as black mura, blobs, corner light, line and spot mura, and more.
