Abstract
A method and device for increasing the effective horizontal resolution of a display device. One embodiment forms a cardinal array of digital micromirror elements by staggering alternate rows in an array. According to a second embodiment, an ordinal pixel array 57, is converted to a cardinal pixel array, by grouping SLM elements 59, 61, 63, and 65 into a pixel block 58. All of the elements in a pixel block are controlled in unison such that the pixel block acts like a single pixel. Rows of pixel blocks 67 and 69 are offset to provide the effect of a cardinal array of pixels without the decrease in efficiency sometimes associated with cardinal pixel arrays.
