Abstract
A pair of viewing glasses, a three-dimensional (3D) display system and an image beam adjustment method are provided. The adjustment method includes determining an adjustment angle according to an image beam emitted by a display screen; detecting a relative spatial orientation of the viewing glasses and the display screen; determining a compensation angle according to the relative spatial orientation; and adjusting the polarization direction of the image beam according to at least one of the adjustment angle and the compensation angle, so as to change the polarization direction of the image beam to a target polarization direction parallel or perpendicular to the polarization axis direction of a polarizer of the viewing glasses.
