Abstract
A display comprises a backlight (-) and a spatial light modulator () such as a liquid crystal device for modulating light from the backlight (-). The backlight has a light-output surface () with a first set of regions in the form of parallel evenly spaced strips (). In a multiple-view mode of the display, these strips () emit light whereas the remainder of the output surface () is dark. In a single-view mode of operation of the display, the whole of the output surface () emits light substantially evenly across the display area of the modulator ().
