OPTICAL DEVICE ARRAYS WITH OPTIMIZED IMAGE RESOLUTION

摘要

Optical devices comprising addressable pixels are tiled in an array (210) configured for generating an image line. The addressable pixels are grouped into center pixels (214) and addressable sub-pixels (218) are grouped at the ends (215A, 215B, 216A and 216B). 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 to generate image lines for display and print applications. The optical devices can be any light valves including MEM devices such as diffraction grating light valves and LCD devices.
