Abstract: An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.

Abstract: A backlit light display comprises a light guide panel (3), a prismatic film (12), an asymmetric top diffuser (15) and a LCD (10). A linear light source (2) is disposed along a side face (33) of the light guide panel (3). Light from the linear light source (2) is transmitted though the light guide panel (3) where it is spread and uniformly output through a front face (31) to the prismatic film (12). Light (4) incident on the prismatic film (12) is redirected more along a first direction than along a second direction. This light (4) is directed more normal to the LCD (10). An asymmetric diffuser (15) is applied between the prismatic film (12) and the LCD panel (10) to smear the periodic information from the prismatic film (12) and eliminate the Moiré fringe pattern resulting from interference between the periodic structure of the prismatic film (12) and the periodic arrangement of pixels in the LCD (10). The asymmetric diffuser (15) is aligned with respect to the prismatic film (12) such that it scatters and spreads light more in a second direction than the first direction.

Abstract translation: 背光灯显示器包括导光板（3），棱镜膜（12），不对称顶部扩散器（15）和LCD（10）。 线状光源（2）沿着导光板（3）的侧面（33）设置。 来自线状光源（2）的光通过导光板（3）传播，在其中被扩散并且通过正面（31）均匀地输出到棱镜膜（12）。 入射在棱镜膜（12）上的光（4）沿着第一方向比沿着第二方向更多地被重定向。 该光（4）更直接地指向LCD（10）。 在棱镜膜（12）和LCD面板（10）之间施加不对称漫射器（15）以从棱镜膜（12）上涂抹周期性信息，并消除由棱镜膜（12）周期性结构之间的干涉引起的莫尔条纹图案 膜（12）和LCD（10）中的像素的周期排列。 不对称扩散器（15）相对于棱镜膜（12）对准，使得其在比第一方向更靠第二方向上散射和扩散光。
