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 ().

Display including backlight operable in 2D and 3D modes

A display is provided having first and second direct view modes of operation. The display comprises a liquid crystal display panel and a backlight which is illuminated during the first mode so that the displayed image is visible throughout an extended viewing region in front of the device. The display also comprises a holographic element and a front light source, which is switched on for the second direct view mode. The holographic element redirects light from the front light source into part of the extended viewing region so that an image displayed by the device is visible in only a restricted portion of the viewing region.
