摘要： A method of fabricating an electrically-controlled birefringence cell. The cell has a cell gap no more than 20 micrometers. The cell has an alignment layer arranged to impart a pretilt on liquid crystal in contact with the alignment layer. The method comprises processing the alignment layer to achieve a surface anchoring value between the liquid crystal and alignment layer of less than 1 mJ/m2.

摘要： There is provided a driver for a spatial light modulator comprising a plurality of pixels. The driver is configured to receive a hologram of a picture and drive the spatial light modulator to display the hologram on a group of pixels of the plurality of pixels. The driver is further configured to apply a series of phase offsets to the spatial light modulator displaying the hologram, wherein each phase offset of the series of phase offsets is applied to each pixel of the group of pixels for a respective predetermined period of time.

摘要： There is provided a display device comprising a substrate; a spatial light modulator and a sealing element. The spatial light modulator is mounted on the substrate and comprises a light modulating region and an electrical connection region adjacent to the light modulating region. The sealing element comprises a primary portion comprising a first material and a secondary portion comprising a second material. The primary portion of the sealing element extends around at least a portion of a perimeter of the light modulating region and the secondary portion of the sealing element extends over the electrical connection region. The first material has a first coefficient of thermal expansion that is greater than a second coefficient of thermal expansion of the second material.
