2.7 Driver Requirements - DLP4621Q1EVM

The DLP4621-Q1 chipset, used with LED illumination, requires illumination modulation. This LED modulation turns off the light output during micromirror reset, which improves system contrast. For the system timing specifications of the DLP462`1-Q1 electronics EVM, see Figure 2-7
