Measuring and modeling per-element angular visibility in multi-view displays

— Multi-view displays employ an optical layer which distributes the light of an underlying TFT-LCD panel in different directions. Certain properties of the layer create specific artifacts, such as ghost images, moire patterns, and masking. The layer was modeled as an image-processing channel, and the display parameters related with the model were identified, which are importantfor the design of image-processing algorithms for artifact mitigation. The identified parameters are interleaving pattern, angular visibility, and frequency throughput of the display. A methodology for deriving these parameters for an arbitrary LCD-based multi-view display are presented, which does not require precisely positioned measurement equipment. As a case study, measurement and modeling results for a particular multi-view display are also presented.
