Abstract
An SLM-based video receiver (,) receives a video input of some standardized format at a signal interface unit (,) and passes the input to a processor (,). The processor (,) performs analog-to-digital conversion if the pixel data is analog and also performs other enhancements to prepare the pixel data for loading into a video memory (,). The pixel data from the processor (,), representing a field of pixel data, is stored into the memory (,) for loading into rows of pixel elements of a spatial light modulator (,). The spatial light modulator (,) receives the pixel data in rows and each individual pixel element responds accordingly. The pixel elements of the spatial light modulator (,) emit light or reflect light from a source (,) and generate a video frame for display on a screen (,). By exploiting the addressing functions of the spatial light modulator (,), the SLM-based video receiver (,) displays a video frame using a field of pixel data.
