  • Directional backlight, a multiple view display and a multi-direction display
    Patent number: 8154686
    Abstract: A directional backlight, a multiple view display and a multi-direction display A multiple view display (18) comprises a directional display device (19) for displaying a first image or sequence of images so as to be mainly visible from a first range of directions relative to the device and for simultaneously displaying a second image or sequence of images so as to be mainly visible from a second range of directions relative to the device different from the first range. The display (18) further comprises a directional backlight (20) for directing light through the display device (19) at least mainly in the first and second ranges. Since the directional backlight (20) directs light through the display device (19) at least mainly in the first and second ranges, the display provides users located in the first and second ranges with images of greater intensity than a conventional display.
