Abstract: An one-way homogeneous beam expanding screen (20) and a three-dimensional display device. The one-way homogeneous beam expanding screen (20) comprises a lenticular grating (22) and at least one linear Fresnel lens (21); the linear Fresnel lens (21) is located between a projection unit (10) and the lenticular grating (22); the linear Fresnel lens (21) comprises a plurality of tooth-shaped structures (211) extending in a second direction (x); the linear Fresnel lens (21) is used for deflecting a light beam emitted by the projection unit (10) and enabling the deflected light beam to be normally incident to the lenticular grating (22); a grating line (221) of the lenticular grating (22) extends along the second direction (x); the lenticular grating (22) is used for uniformly expanding a light beam emitted by the linear Fresnel lens (21) along a first direction (y), wherein the first direction (y) intersects with the second direction (x).

Abstract: Embodiments of the present disclosure describe a light-field display system including a rotatable display screen subsystem, a display screen positioning apparatus, an eye tracking subsystem, and a computer. The rotatable display screen subsystem includes a lamp pole. The lamp pole includes a lamp panel. The lamp panel includes a vector pixel array. The display screen positioning apparatus includes a plurality of lasers and a photosensor. The computer device is connected to the rotatable display screen subsystem and the eye tracking subsystem. The lamp panel controller is configured to determine a position of the lamp panel according to sensed data of the display screen positioning apparatus. Each vector pixel on the lamp panel displays display content in a display direction to achieve 3D image display.
