Spatial light modulator and directional display

摘要

A spatial light modulator comprises a plurality of picture elements arranged as rows and columns. The columns are arranged as adjacent groups, for instance for association with an element of a parallax device to provide an autostereoscopic 3D display. Adjacent picture elements disclosed in each row and in adjacent columns of each group overlap horizontally so that there are overlapping regions and non-overlapping regions. The vertical extent of each picture element is substantially constant throughout the non-overlapping region and is substantially equal to the sum of the heights of the adjacent picture elements throughout the overlapping regions.
