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

Abstract— 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, moiré 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.
