Patent ID: 8885123

Claim:
A three-dimensional (3D) display apparatus, characterized in that: the 3D display apparatus comprises a display and a liquid crystal cell module, and the display comprises a polarizer, and the liquid crystal cell module comprises a ferroelectric liquid crystal cell for retarding a phase of the light emitted from the display and corresponding to a display frame, as well as forming a left-handed circularly polarized light and a right-handed circularly polarized light of the display frame; wherein the liquid crystal cell module comprises the ferroelectric liquid crystal cell and a ¼ wave phase retarder, and the ferroelectric liquid crystal cell has a ½ wave phase retardation, and the ferroelectric liquid crystal cell and the ¼ wave phase retarder are bonded to a light-output surface of the display, and a 22.5 degree angle is therebetween an absorption axis of the polarizer of the display and the orientation of the ferroelectric liquid crystal cell, and the ¼ wave phase retarder is parallel to the absorption axis of the polarizer of the display, and an electric field is applied across the ferroelectric liquid crystal cell to alter a polarization direction thereof.
