    • A projection device is disclosed. The projection device comprises a plurality of LEDs (202, 204, 206) each generating light of a known wavelength, a light path associated with, and receiving the light from, each of the LEDs, each light path comprising a VA wavelength retarder (213, 223, 233), a first optical selection means (243, 253, 263)) providing orientation of a known direction to light applied thereon, the first optical selection means further reflecting light having an orientation not in the known direction, an LCD panel (232, 234, 236, and a second optical selection means (245, 255, 265) providing orientation of light applied thereon substantially orthogonal to the first known direction, and a recombination cube (240) in communication with each of the light paths for recombining the light received from each of the light paths, wherein the orientation of light received from at least one light path is substantially orthogonal to the orientation of light received from the remaining light paths.

    • 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.
    • 一种可切换的自动立体显示装置,包括:具有用于产生显示的显示像素阵列的显示面板,所述显示像素以行和列排列; 布置在所述显示面板上方的用于引导所述显示像素的光输出以提供立体图像的透镜元件的阵列,所述透镜元件包括电光材料,所述电光材料的折射率可通过选择性地施加电场 保持光输出定向功能的第一值和去除光输出定向功能的第二值; 以及设置在透镜元件上方和下方的电极布置,用于跨越透镜元件施加电场。 电极装置中的至少一个包括由电介质层隔开的第一和第二电极层,并且每个电极层包括由间隙分开的多个平行细长电极。 每个电极层的电极与另一个电极层的间隙对准。 以这种方式,减小了间隙对透镜元件中的电场的影响。
