Spatial light modulator and directional display

摘要

A liquid crystal spatial light modulator comprises columns and rows of picture elements (24-26). The columns are arranged as groups of columns, for instance under respective parallax generating elements in an autostereoscopic 3D display. The picture elements (24-26) are arranged as sets to form colour picture elements such that the picture elements (24-26) of each set are disposed at the apices of a polygon, such as a triangle (21), and are disposed in corresponding columns of the groups of columns.
