摘　　要：We propose a one-dimensional integral imaging （1DII） display that consists of a display panel and a gradient-aperture parallax barrier. The gradient-aperture parallax barrier is symmetrical, and its slit widths gradually increase from both sides to the middle. The leftmost and rightmost slits are used to fix the viewing angle, whereas the other slits are used to increase the optical efficiency. A prototype of the proposed 1DII display is developed. Its optical efficiency is higher than that of the conventional display, but the viewin~ an^les are the same.We propose a one-dimensional integral imaging （1DII） display that consists of a display panel and a gradient-aperture parallax barrier.
