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.
