Systems and methods for increasing spatial or temporal resolution for dual modulated display systems

摘要

Dual modulation display systems comprising a first modulation layer and a second modulation layer are disclosed, such that the first modulation layer and the second modulation layer are offset by a desired distance. In one embodiment, the offset distance may be an actual spatial offset distance in one, two or a preferred direction. In another embodiment, the offset distance may be a rotational offset between the two layers. In yet another embodiment, the offset may be a temporal offset between the images appearing on the first modulation layer and the second modulation layer. In yet another embodiment, the offset may be a combination of spatial, rotational and/or temporal offsets. The display system may comprise a controller capable of mapping input image data onto the first and second modulation layers via intermediate signals and the intermediate signals may be some function of the offset.

1. A display system, said display system comprising:
a first modulation layer; a second modulation layer; wherein said first modulation layer capable of transmitting a first modulated light to said second modulation layer and wherein further said second modulation layer capable of transmitting a second modulated light; wherein further said first modulation layer is offset from said second modulation layer by a first distance; a controller, said controller capable of receiving input image data and sending intermediate signals to said first modulation layer and said second modulation layer; and said controller capable of mapping said input image data into said intermediate signals as a function of said first distance.
