Abstract
A holographic display apparatus and a holographic display method are provided. The holographic display apparatus determines a representative depth from 3D image data; calculates a computer generated hologram (CGH) corresponding to the representative depth on the 3D image data; obtains the modulated CGH by modulating a phase of the CGH to increase an eye box; modulates a light according to the modulated CGH and generates a hologram image; and forms the generated hologram image at the representative depth.
