Measurements on Displays and Backlights
Optical parameters of displays and its components can be measured into the laboratories but also into the production e.g. for white balancing.
New display technologies require special methods of light-technical evaluations. E.g. the evaluation of mechanical stress of displays due to mounting is being done by measurements of gradients of light (BlackMURA).

Know-How - BlackMURA Rating of Visual Effects
The analysis of display screen quality according to the Automotive OEM workgroup BlackMURA standard of the DFF is based onto visual ratings of local and global non-uniformities.
Into the video, the background of visual perception is being discussed:
- How do non-uniformities appear visually
- Using spatial frequencies into perception models
- Options to rate global and local non-uniformities

Display Uniformity

Angular ISO-Contrast and ISO-Color
Conoscopic measurements of Luminance and Color for viewing angles of ±60° on displays and diffuse materials

Sticking Images
