The periodic structure of liquid crystal display pixels and the cylindrical lens array often leads to generating Moiré patterns within a specific range of cylindrical lens tilt angles in three-dimensional light field displays. These patterns overlay display contents, significantly degrading the viewing experience. A common approach to mitigate Moiré involves adjusting the tilt angle of the cylindrical lens array. To identify optimal tilt angles for suppressing Moiré, this study proposes a Moiré pattern visualization simulation method based on the segmentation analysis of cylindrical lens array units. Using geometric optics principles, the imaging characteristics of individual cylindrical lens units are analyzed, and the resultant imaging outputs are simulated. The simulated images are then stitched to reconstruct the complete light field display, enabling Moiré pattern visualization. Experimental results demonstrate that the proposed method effectively visualizes the overall light field display and its local structures. Additionally, the tilt angle of the cylindrical lens array can be adjusted within the range of 0° to 90°. The simulation accurately predicts Moiré patterns for various light field display devices and provides valuable guidance for determining the optimal tilt angle of the cylindrical lens array.
