Papers Time-Division Quadruplexing Parallax Barrier with Subpixel-Based Slit Control

This paper presents a full-HD autostereoscopic display with a wide viewing zone based on time-division multiplexing slanted parallax barrier with subpixel-based slit control. A slanted directional diffuser placed between the barrier panel and the image panel suppresses moir_ by mixing light from RGB subpixels. By constituting the parallax barrier along with this slanted diffusion line, control of the barrier by subpixel unit is enabled. By introducing subpixel-based phase shift and slit width control to time-division quadruplexing parallax barrier, viewing zone free from crosstalk is enlarged notably. Theoretical viewing zone is calculated and compared with the experimental results using a prototype hardware. The overall crosstalk of the prototype is also measured to confirm the effectiveness of the proposed method.
