Image data can be loaded into parallel flash memory to load to DDR2 memory at startup to be displayed, or can be loaded over USB or the SPI port directly to DDR2 memory to be displayed. Binary (1-bit) or grayscale (8-bit) patterns can be displayed. The memory will hold 960 binary patterns or 120 grayscale patterns.
Binary (1-bit) patterns can be displayed at up to 5000 binary patterns per second. These patterns assume a constant illumination and do not depend on illumination modulation
Grayscale (8-bit) patterns assume illumination modulation in order to achieve higher pattern rates. When the pattern rate requires that the lower significant bit(s) be shorter than the rate that the DMD can be switched, these bits will require the source to be modulated to achieve the shorter time required. The trade-off is dark time during these bits. At the maximum 500 Hz grayscale pattern rate, the dark time approaches 75%.
