P‐3.5: Research on Reducing Moiré Patterns in Naked‐eye 3D Displays through Optimizing Lenticular Lens Tilt Angle

Abstract

In the domain of Naked‐eye 3D display technology, the periodic interference between lenticular lens and screen subpixels frequently results in the generation of moiré patterns, which significantly impair image quality. This study proposes a strategy to reduce moir é artifacts by adjusting the tilt angle of the lenticular lens. Relying on the human eye sensitivity function, we have conducted a thorough analysis of the moiré patterns caused by the interference between the lenticular lens and the screen at various tilt angles. After extensive research, it has been discovered that the analytical method which applies spectral sensitivity weighting subsequent to the consideration of the human eye sensitivity function aligns more closely with the actual perception of moiré patterns by the human eye. This approach enables a more precise determination of the optimal tilt angles for lenticular lenses and screens, thereby substantially minimizing the moiré effect. The implications of this finding are significant for the realization of high‐quality, high‐definition naked‐eye 3D image displays, and may positively contribute to advancements within this technical field.
