MURATest-MVP Applications

 

For Emissive applications

MURA MVP is useful to analyze light emission of displays at pixel level. All the defects related to the pixel structure can be detected and quantified (homogeneity within pixel, punctual defects, alignment defects...). The dispersion at pixel level in terms of color and luminance can be quantified.

Color & luminance measurement on 15’ LCD display: The luminance of each type of pixel is measured in ON state and OFF state;
The impact of the spacers on the contrast is observed.

 

 

For Reflective applications

With optional integrated RGB illumination, reflective properties can be checked at pixel level. The structure and homogeneity of the diffusing mirror generally used in these devices can, for example, be observed directly . Also micrometric structures of optical components like, for example, BEF films can be visualized and quantified.
