7.2 Typical Application

The DLP991U DMD is a 4096 × 2176 resolution DLP digital micromirror device. When combined with the TI DLPC964 industrial controller and other electrical, optical and mechanical components the DLP991U DMD provides a superior solution for industrial direct imaging and 3D printer applications. Figure 7-1 shows a typical single-chip system application using the DLP991U DMD.
