Autostereoscopic 3D display with high brightness and low crosstalk

An autostereoscopic 3D display with high brightness and low crosstalk is proposed. This display consists of a liquid crystal display (LCD) panel, a reflective light source (RLS), and a parallax barrier or lenticular lens. The RLS behind the LCD panel consists of a light source, a light guide plate, and a reflection cavity. The RLS can make light reflect continuously in the reflection cavity and exit from the slits on the cavity surface. The widths of these slits are narrower than those of the subpixels, so they can provide a low aperture ratio, which is helpful in obtaining low crosstalk. Because of the reflection cavity, the optical efficiency is higher than that using a single barrier. The parallax barrier or lenticular lens can project parallax images on the LCD panel into different directions. Then 3D images are formed. A prototype of the proposed 3D display having high brightness 3D images and low crosstalk is developed. The experimental results agree well with the theory.
