The authors present an energy-efficient integral imaging system with suppression of pseudo images, which are caused by a leakage of rays from each elemental image to the adjacent elemental lenses. The leakage of rays can be decreased when the lens is paired with a segmented backlight with limited aperture, which consumes less electricity. To remove the leakage of rays completely without damaging the image to be presented, three modifications are implemented. First, a lens with a larger focal distance is used to decrease aberration. Second, a lens array composed of thick elemental lenses is used so that the leakage of rays can be blocked by the rough surface on the side of the thick lens. Third, the aperture of the segmented backlight is expanded to avoid loss of light in the right image.
