Multiple view directional display with parallax optic having colour filters.

摘要

A directional display, such as an autostereoscopic display or dual view (right and left image) display, comprises an image display device having picture elements 8 and a parallax optic comprising an array of colour filters 13. The colour filters may transmit more than one primary colour and each picture element may emit light of a primary colour. The set of picture elements or pixels 8 may be illuminated by an array of light sources, which may emit light of a secondary colour. The colour filters may be aligned with the picture elements, have opaque 14 or transparent (15, Figure 10) regions for blocking or transmitting light of all three primary colours, be of a secondary colour, and may be arranged in apertures in the parallax optic. A periodically repeating pattern of colour filters may be provided. Filters may be arranged such that a region at 90 degrees or perpendicular to the display appears dark (see region 26 in Figure 7(c)). Filters may overlap - see Figure 17a for example.
