  • Patent number: 7379130
    Abstract: An electro-optical display includes a light source and a Polarization Separation Element (“PSE”) coupled to the light source. The PSE generates a first output having a first polarization state and a second output having a second polarization state. The display further includes a Hetero Polar Light Guide (“HPLG”) that includes a first region optically isolated from a second region and coupled to the PSE. The first output of the PSE is directed into the first region and the second output of the PSE is directed into the second region, and the first region and second region output light in substantially the same direction.

  • Patent number: 7375784
    Abstract: A method is provided that allows simultaneous control of macroscopic azimuthal and zenithal liquid crystal alignment (?, ?) across a liquid crystal layer by controlling the area ratios between first, second and third different types of alignment region (T1, T2, T3) in a patterned alignment layer, the three different types of alignment region (T1, T2, T3) tending to induce liquid crystal alignment in the liquid crystal layer in three different respective, non-coplanar, principal orientations (z, x, y). In the illustrated example, the first type of alignment region (T1) tends to induce substantially homeotropic alignment (in the z direction) and the second and third types of alignment region (T2, T3) tend to induce substantially planar alignment in different, orthogonal, principal orientations (in the x and y directions).
