Abstract:
An optical element comprising a stacked liquid crystal (LC) structure for rotating polarization (e.g., handedness) of an incident circularly polarized light over a broad wavelength and incident angle for head-mounted displays (HMD)s display application is proposed. The stacked LC structure has a dual cell structures, which includes at least a first LC cell and a second LC cell, and the stacked LC structure rotates the polarized light for a broad band of light (e.g., visible spectrum) over a given field a view. The performance of designed dual LC cells structures may be optimized for narrow band wavelength and a narrow incident angle for different application cases.

Claim (Index 1):
A stacked liquid crystal (LC) structure comprising:\n a plurality of LC cells configured to rotate a polarization of a broadband light over a range of wavelengths and a range of incident angles, the plurality of LC cells are arranged in a stack such that the broadband light passes through each of the plurality of LC cells consecutively, wherein an amount of phase adjustment caused by the plurality of LC cells stack is wavelength independent over the range of wavelengths and the range of incident angles and the plurality of LC cells are oriented relative to each other such that a cumulative rotation of the polarization for all bands of light within the broadband light is from a first polarization to a second polarization.
