Abstract

A method and device for increasing the effective horizontal resolution of a display device. One embodiment of the invention forms a cardinal array of digital micromirror elements by staggering alternate rows in an array. According to a second embodiment of the claimed invention, an ordinal pixel array, is converted to a cardinal pixel array, by grouping SLM elements into a pixel block. 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 axe offset to provide the effect of a cardinal array of pixels without the decrease in efficiency sometimes associated with cardinal pixel arrays.
