    • A switchable autostereoscopic display device comprising: a display panel having an array of display pixels for producing a display, the display pixels being arranged in rows and columns; an array of lens elements arranged over the display panel for directing the light output of the display pixels so as to provide a stereoscopic image, the lens elements comprising an electro-optic material whose refractive index is switchable by selective application of an electric field between a first value that maintains the light output directing function and a second value that removes the light output directing function; and electrode arrangements provided above and below the lens elements for applying the electric field across the lens elements. At least one of the electrode arrangements comprises first and second electrode layers separated by a dielectric layer, and each electrode layer comprises a plurality of parallel elongate electrodes separated by gaps. The electrodes of each electrode layer are aligned with the gaps of the other electrode layer. In this way, the effect of the gaps on the electric field in the lens elements is reduced.

    • An autostereoscopic image output device comprises an image panel having an array of image pixels (5) defining an image, the image pixels being arranged in rows and columns. An array of parallel lenticular elements (11) is positioned over the image panel, the lenticular elements having optical focal axes that are slanted at an angle (φ) to the image pixel columns. The image output device is operable in first and second modes, with the image panel and lenticular element array rotated by 90 degrees between the modes, thereby providing a landscape mode of operation and a portrait mode of operation, the slant angle φ in the landscape mode satisfies: 1≧tan φ≧1/2. This enables a 3D image device to be used in both the landscape and the portrait mode, while maintaining a good view-distribution and image pixel structure.

    • An autostereoscopic display device comprising a view forming module in registration with an image forming means. The image forming means has an orthogonal array of display pixels spatially defined by an opaque matrix. The view forming module provides at least two optical functions, namely a view forming function and a brightness non-uniformity reducing function. The view forming function modifies the direction of outputs of the display pixels such that the outputs of groups of the display pixels are projected in respective different directions as a plurality of views. The view forming function is provided by an array of parallel lenticular lenses arranged across the view forming module and having a first pitch. The brightness non-uniformity reducing function spreads the outputs of the display pixels such that brightness non-uniformities caused by imaging of the opaque matrix are reduced. The brightness non-uniformity reducing function defines a second pitch across the view forming module less than the first pitch, and further defines an effective spreading angle in a plane perpendicular to axes of the view forming elements substantially equal to or less than the angle between adjacent views projected by the view forming function. The brightness non-uniformity reducing function is provided by an array of lenses or a diffuser. In the case of an array of lenses, these lenses may be integrated with the lenticular lenses providing the view forming function in the form of lenses having a polygonal cross section.
    • 一种自动立体显示装置,包括与图像形成装置对准的视图形成模块。 图像形成装置具有由不透明矩阵空间限定的显示像素的正交阵列。 视图形成模块提供至少两个光学功能,即视图形成功能和亮度不均匀性降低功能。 视图形成功能将显示像素的输出的方向修改为使得显示像素的组的输出在各个不同的方向上投影为多个视图。 视图形成功能由平行双凸透镜阵列提供,横列于视图形成模块并具有第一间距。 亮度不均匀性降低功能扩大显示像素的输出,使得由不透明矩阵的成像引起的亮度不均匀性降低。 亮度不均匀性减小功能限定视野形成模块的第二间距小于第一间距,并且还在垂直于视图形成元件的轴线的平面中限定有效扩展角度,该平面基本上等于或小于相邻 由视图形成功能投影的视图。 亮度不均匀性降低功能由透镜阵列或扩散器提供。 在透镜阵列的情况下,这些透镜可以与提供具有多边形横截面的透镜形式的视角形成功能的双凸透镜一体化。
