Moiré interference in multilayered displays

Moiré interference in multilayered displays Abstract— Multi‐layered displays contain a pair of parallel liquid‐crystal‐display panels spaced apart from each other. The viewer sees objects displayed on the front and rear layers to form a three‐dimensional image. Each layer has an array of pixels arranged in an RGB striped configuration. When imaged on the retina, the layers interact to produce a beat pattern referred to as moiré. This pattern can be distracting to people seeking to use a multi‐layered display. To solve this problem, the high‐frequency components on the rear most display are attenuated using an interstitial optical diffuser. Given the characteristics of the diffuser and imaging planes, a function is derived to calculate the amount of residual moiré interference present. A measurement device and methodology was constructed to quantify the amplitude of the beat pattern and the blur on the rear image plane in terms of the human visual system. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Society for Information Display Wiley

Abstract

Abstract— Multi‐layered displays contain a pair of parallel liquid‐crystal‐display panels spaced apart from each other. The viewer sees objects displayed on the front and rear layers to form a three‐dimensional image. Each layer has an array of pixels arranged in an RGB striped configuration. When imaged on the retina, the layers interact to produce a beat pattern referred to as moiré. This pattern can be distracting to people seeking to use a multi‐layered display. To solve this problem, the high‐frequency components on the rear most display are attenuated using an interstitial optical diffuser. Given the characteristics of the diffuser and imaging planes, a function is derived to calculate the amount of residual moiré interference present. A measurement device and methodology was constructed to quantify the amplitude of the beat pattern and the blur on the rear image plane in terms of the human visual system.
