    • A multi-view autostereoscopic display device comprises: a backlight having a plurality of backlight areas arranged in a width direction of the display device; a spatial light modulator arranged over and in registration with the backlight, the spatial light modulator having an array of display forming elements arranged in rows and columns for modulating light received from the backlight; and a view forming layer arranged over and in registration with the spatial light modulator, the view forming layer having a plurality of view forming elements arranged in the width direction of the display device, each view forming element being configured to focus modulated light from adjacent groups of the display forming elements into a plurality of views for projection towards a user in different directions. The backlight is switchable to activate different ones of the backlight areas in different portions of a driving cycle of the display device so that, in the different portions of the driving cycle, modulated light from the active backlight areas is incident on each view forming element with respective different angles of incidence. In this way, the overall viewing angle or the effective three dimensional display resolution may be increased.

    • An optical system that can add an optical depth information to a two-dimensional image (72) represented by substantially collimated light, e.g. by using a collimated light source in front of a LCD display. The optical system includes a first array of optical lenses (70) arranged at a first distance in front of the two-dimensional image (72), and a second array of optical lenses (71) arranged at a second distance in front of the two-dimensional image (72), the second distance being larger than the first distance. Optical properties, e.g. focal length, can be adjusted for the optical lenses of the first and second array of optical lenses (70, 71) in response to the optical depth information. The optical system can serve as an optical front for 3D multiview displays. Depending on embodiment, both horizontal and vertical angular resolution can be obtained, and the front end exhibits only a small brightness loss. Preferably one lens per pixel is used in case of a pixelized image. In one embodiment, a stack of several arrays of on/off switchable optical lenses are arranged at different distances in front of the two-dimensional image, wherein a depth is applied by turning on one lens corresponding to the desired depth distance. In another preferred embodiment two arrays of continuously adjustable lenses are used to generate a depth by adjusting the lenses so as to provide an apparent position in between the two arrays. Preferably, a diffuser is positioned in front of the second array of lenses. Different shapes of lenses may be used such as spherical lenses, lenticular lenses, Fresnel type lenses or “horse-saddle” shaped lenses. The arrays of lenses may be implemented using GRIN lenses or fluid-focus lenses. Preferably, the lenses of each array of lenses are individually adjustable.
    • 一种光学系统,其可以将光学深度信息添加到由基本上准直的光(例如)表示的二维图像(72)。 通过在LCD显示器前面使用准直光源。 该光学系统包括在二维图像(72)的前面以第一距离排列的第一光学透镜阵列(70),以及第二阵列的光学透镜(71),其布置在两个前面的第二距离处 维数图像(72),第二距离大于第一距离。 光学性质,例如 可以根据光学深度信息调整第一和第二光学透镜阵列(70,71)的光学透镜的焦距。 该光学系统可以作为3D多视图显示器的光学前端。 根据实施例,可以获得水平和垂直角分辨率,并且前端仅表现出小的亮度损失。 在像素化图像的情况下,优选使用每像素一个透镜。 在一个实施例中,可以在二维图像之前的不同距离处布置多个开/关可切换光学透镜阵列的叠层,其中通过打开与所需深度距离对应的一个透镜来施加深度。 在另一个优选实施例中,通过调整透镜来使用两个连续可调透镜阵列来产生深度,从而在两个阵列之间提供明显的位置。 优选地,扩散器位于第二阵列阵列的前面。 可以使用不同形状的透镜,例如球面透镜,双凸透镜,菲涅尔型透镜或“马鞍”形透镜。 透镜阵列可以使用GRIN透镜或流体对焦透镜来实现。 优选地,每个透镜阵列的透镜可单独调节。
