Abstract :
A 3D display based on a microsphere-lens (MSL) array is proposed. This 3D display uses the MSL array to project the parallax images on a 2D display panel into different spatial directions. Each MSL can work as a conventional micro-lens. However, the MSL has a much shorter focal length than the conventional micro-lens. The shorter focal length is helpful for increasing the viewing angle. A prototype of the 3D display is developed. Experiment result shows that the proposed display has a large viewing angle and the crosstalk is also limited in a low level.
