Title:
HOLOGRAPHIC DISPLAY METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/062306
Kind Code:
A1
Abstract:
A holographic display method and device. The holographic display method comprises the steps of: obtaining an Nth diffraction order region corresponding to an eye position; calculating a holographic complex amplitude distribution corresponding to an Nth-order diffraction window according to the Nth diffraction order region, and obtaining window hologram information; encoding the window hologram information; and performing loading and display in the Nth diffraction order region according to the encoded window hologram information. By means of the holographic display method and device, the complex amplitude of a hologram is adjusted according to the eye position of an observer, to present a hologram on multiple diffraction orders, thereby expanding the window holographic visible range.
