Abstract
Optical devices comprising addressable pixels are tiled in an array configured for generating an image line. The addressable pixels are grouped into center pixels and addressable sub-pixels are grouped at the ends. The optical devices are tiled in staggered rows with addressable. sub-pixels and/or pixels overlapping along the array. To optimize the quality of the image, addressable sub-pixels are selectively operated and/or disabled to remove artifacts and maximize pixel density in the image line generated by the overlap regions. Arrays of optical devices, in accordance with the invention, are used generate image lines for display and print applications. The optical devices can be any light valve including MEM devices such as diffraction grating light valves and LCD devices.
