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.
提出了一种具有高亮度和低串扰的自动立体3D显示器。该显示器由液晶显示器（LCD）面板、反射光源（RLS）以及视差屏障或柱面透镜组成。LCD面板后方的RLS由光源、导光板和反射腔组成。RLS可使光在反射腔内连续反射，并从腔表面的狭缝射出。这些狭缝的宽度比子像素的宽度窄，因此它们可提供低孔径比，这有助于获得低串扰。由于有反射腔，其光学效率高于使用单个屏障的情况。视差屏障或柱面透镜可将LCD面板上的视差图像投射到不同方向。然后形成3D图像。开发了具有高亮度3D图像和低串扰的所提出的3D显示器的原型。实验结果与理论吻合良好。
