Abstract: A multi-backlight collimated system at least comprises a plurality of light sources, a plurality of reflection elements, and at least a collimation element. The light sources are for providing light. Each reflection element has a reflective surface corresponding to one of the light sources and is disposed to reflect light from the corresponding light source. The reflective surface reflects light being emitted in a predetermined direction by the corresponding light source to form a projection area on a screen. The adjacent projection areas on the screen are joined at adjacent side edges. The collimation element is disposed on the screen for altering a path of light penetrating the screen and emitting light in a specific direction The multi-backlight collimated system is easily fabricated into large sizes and is beneficial for products having large display areas.

Abstract: A three-dimensional display device including a collimated backlight module, a first display panel, a second display panel, and a lens array is provided. The collimated backlight module has a light-emitting surface and provides a light with a divergent angle smaller than 10° from the light-emitting surface. The first display panel having a plurality of first pixels is disposed on the collimated backlight module. The second display panel has a plurality of second pixels corresponding to the first pixels. The first display panel is disposed between the second display panel and the collimated backlight module. A depth distance is formed between the first display panel and the second display panel. The lens array is disposed adjacent to the second display panel and has a plurality of lenses corresponding to the second pixels. Therefore, the three-dimensional display device is capable of providing a wide visual angle and desirable depth characteristics.
