Abstract
A prototype autostereoscopic three-dimensional (3D) light-emitting
diode (LED) display using a cylindrical diffractive optical elements
(C-DOEs) sheet as the optical steering element is proposed. The operation
of the system and the calculation method of the system parameters
are described in detail. The DOEs sheet is placed from a distance
from the LED display panel which is five times smaller of the existing
technology, and the column spacings of the pixels of the LED display
panel are nonequal in order to equalize the distance between the viewing
zones. The prototype has a 1.33 m
$^2$
display panel, 384
$\times$
144
resolution and a horizontal field of view of 60
$^{\circ}$
. The experimental result shows that the proposed method is a potential
autostereoscopic technology for the large area LED displays.
