    摘要： A 3D projection display comprises an autostereoscopic image producing unit which directs light beams corresponding to respective 2D views in different directions towards a projection lens. The projection lens co-operates with the image producing unit to image the light beams at respective different regions in the aperture of the projection lens. A light-transmissive screen co-operates with the image producing unit and the projection lens to image the views at the screen. The screen may comprise a Fresnel lens, or where a magnified image of increased angular spread is required, a double lenticular screen angular amplifier.

    摘要： A three dimensional display is provided which can. operate in an autostereoscopic mode, requiring no viewing aid, and a stereoscopic mode, requiring a viewing aid such as polarized spectacles. In the autostereosocopic mode, light from illuminators is imaged by lenses through LCD display panels at regions where the left and right eyes of an observer are located. Thus, a two dimensional image displayed on one panel is visible to the right eye of the observer whereas a two dimensional image displayed by the other panel to visible to the left eye of the observer. In the stereoscopic mode, light from the illuminators through the LCD panels is visible throughout an extended region by both eyes of the observer. However, the light from the panels is polarized in mutually perpendicular directions and the spectacles comprise polarizers for the left and right eyes which substantially pass only light corresponding to the left and right images, respectively.

    摘要： A directional display comprises a display arrangement such as a spatial light modulator and a rear parallax barrier illuminated by a suitable backlight. The spatial light modulator and the parallax barrier cooperate to produce Fresnel diffraction which results in spatially non-uniform brightness across viewing windows of the display. Also, where the spatial light modulator has pixels of non-constant vertical aperture, further variations in the intensity profile at the windows occurs. In order to compensate for this, a mask is provided, for instance between the parallax barrier and the backlight. The mask cooperates with the parallax barrier to produce an intensity pattern having variations which are the inverse of the variations in intensity pattern produced by the parallax barrier and the spatial light modulator. The variations are superimposed and substantially cancel each other out so as to result in viewing windows which have substantially uniform light intensities.
