Moiré-reduction method for slanted-lenticular-based quasi-three-dimensional displays

• A method to minimize moiré patterns in lenticular-based Q3D displays is proposed.
• The specific angle is determined based on the Fourier transform function.
• The designed film offers good 3D effect with stabilized 3D contrast and moiré-free.
• The proposed film can provide 3D images in both portrait and landscape modes.

In this paper we present a method for determining the preferred slanted angle for a lenticular film that minimizes moiré patterns in quasi-three-dimensional (Q3D) displays. We evaluate the preferred slanted angles of the lenticular film for the stripe-type sub-pixel structure liquid crystal display (LCD) panel. Additionally, the sub-pixels mapping algorithm of the specific angle is proposed to assign the images to either the right or left eye channel. A Q3D display prototype is built. Compared with the conventional SLF, this newly implemented Q3D display can not only eliminate moiré patterns but also provide 3D images in both portrait and landscape orientations. It is demonstrated that the developed slanted lenticular film (SLF) provides satisfactory 3D images by employing a compact structure, minimum moiré patterns and stabilized 3D contrast.
